Question:

15X6 6/5.5 Silver Mod Trailer Wheel

the info above is the wheels i am interested in that you sell.

when i measure my 6 bolt/lug wheel. i measured from the center of Hole #1, skipped Hole 2 and ended my diagonal measurement at center of Hole #3. i came up with 5.5" is that correct??

Answer:

When measuring a 6 bolt wheel you will want to measure the diameter of the bolt circle. So if you were to draw a circle through all of the bolt holes, the diameter of that circle is your bolt circle.

You will be Measuring the distance between the two holes directly across from eachother. ( Measuring from center of the bolt hole on one side, to center of the bolt hole on the other)

for a picture and complete instructions, view this page. Our 6/5.5 wheels are 5.5" from center to center as instructed above.

If you have any other questions feel free to ask!!

Hi Guys, ... will these fit an automotive rim, one that goes onto a trailer, to be towed at speeds approx 65-70 mph on the freeway, please advise. Thanks.

Answer:

12 Inch Beadlock Chrome A/t Wheel Covers
These wheel covers are designed for golf carts and some trailers. They are designed to snap into any standard steel trailer or golf cart rim. Because there are different styles of automotive steel rims, I cannot confirm or deny that this wheel will work. The wheel cover attaches the same way any other automotive wheel cover would. As long as the center portion of the wheel doesn't bulge outward ( as to affect where the Wheel cover would sit ) you shouldn't have a problem. Because it will fit a 12" steel rim no matter if its for a trailer or automobile, just as long as there is clearance.

The wheel cover sits inside the rim 3/4" - 1"

How to Know What Size Rim You Need for Your Trailer

2011-11-19T11:57:00.001-08:00

So you had a blow out, and your rim is absolutely ruined. Luckily you had a spare ( smart! ) , So you throw on your spare and carry on. But now its time to replace that spare. How do you know what size rim you need to buy? I mean the tire is easy ( as long as you can read ) but how on earth are you supposed to know what size rim to get?

Rims have several specifications that make each rim unique. Here is an example of a rim size:

15 x 5 5/4.5

Diameter Width Bolt Pattern

The first part is easy. Look at the tire size, the last number in the tire size indicates the rim diameter.

So for example: 205/75D15

The "15" indicates that you need a 15" rim.

Well that was easy. Hope I didn't loose anyone yet ;)

Next you need to determine the width of the rim.

Trailer wheels come if different widths, Some common widths are 15x5, 15x6, 15x7. My Point being you wouldn't want to mount your 205/75D15 tire on a 15x7 inch rim. Your Tire would be very stretched and wear unevenly.

At RecStuff.com, we often get questions regarding the bolt pattern of our customer's wheels. While a 5-Bolt on 4.5" is standard and by far the most common among trailer wheel 5-bolt patterns, there are times in which the trailer manufacturer uses a different pattern such as 5 on 5".

When purchasing a trailer, you will want to make sure that the bolt pattern on the wheels of the trailer are standard among the industry. This will ensure that in the case of flat tire or damaged wheel, you will be able to find a replacement when you need it.

Standard sizes include 4-bolt on 4", 5-bolt on 4.5", 6-bolt on 5.5", and 8-bolt on 6.5". If you're unsure about your 5-bolt pattern, we've put together a simple 'bolt pattern template' that makes it easy to ensure you purchase the correct trailer wheel for your trailer.

Measuring Bolt Patterns on a Trailer Wheel/Rim

2011-11-18T13:18:00.001-08:00

Measuring 4-Bolt Trailer Wheels

Measure a four bolt wheel from the center of a bolt hole, skip one bolt hole and then the center of the next hole. Basically your ruler goes across the center of the wheel.

Measuring 5-Bolt Trailer Wheels

Measure a five bolt wheel from the edge of one bolt hole, skip one bolt hole and then the center of the next hole. In this case the ruler is not across the center of the wheel and you measure from the edge of one to the center of the other.

Measuring 6-Bolt Trailer Wheels

Measure a six bolt wheel from the center of the bolt hole, skip 2 bolt holes and then the center of the next hole. Your ruler goes across the center of the wheel.

Measuring 8-Bolt Trailer Wheels

Measure an eight bolt wheel from the center of a bolt hole, skip 3 bolt holes and then the center of the next hole. Your ruler goes across the center of the wheel.

How to Determine The Age of a Trailer Tire

Trailer Tire Specifications

2011-11-18T12:52:00.001-08:00

Structure:

The structure of a trailer tire comes in two different forms, bias ply and radial. Each has it's own benefits. Read more about the differences and similarities at our Radial vs. Bias Ply Trailer Tires (What’s The Difference?) information page.

Ply Rating:

The ply rating on trailer tires typically varies between 2(A) and 10(E). This ply rating is intended to indicate the strength of the tires construction relative to other ply ratings. It doesn't necessarily mean that the tire is manufactured with this specific number of plys or layers. The strength or ply rating of the tire is positively correlated with the load capacity each tire can handle. A higher ply rating results in a stronger tire that can handle a higher load capacity.

Sidewall (In.):

The sidewall figure specifies the distance between the tire sidewall's outermost point when inflated. This metric is paramount when determining the amount of clearance you will have horizontally once the tire assembly is installed.

Outside Dia. (In.):

The outside diameter figure specifies the height of the tire when inflated. This metric is paramount when determining the amount of clearance needed vertically once the tire assembly is installed.

Load Capacity (65mph):

Unlike automotive tires, all ST tires are tested and rated at 65MPH. This 65MPH test allows the tire to qualify as a high speed tire. Every ST Trailer Tire you see on the highway goes through this exact same test regardless of tire size or manufacturer. The advertised load capacity on the sidewall of the tire is approved at this speed with proper inflation.

Max PSI:

The Max PSI is the maximum amount of air pressure the manufacturer suggests to be used in that particular tire. It is advised not to exceed this number as it can inhibit the structure of your tire and make it unsafe to operate.

Trailer Tire Sizing

The tires on a boat trailer might be labeled: ST175/80D13 C

*ST - These tires are for a trailer (Specialty Tire for trailer use only)
*175 - The maximum width of the tire is approximately 175 mm at the widest point
*80 - Indicates the height of the sidewall is 80% of the width (in this case 140 mm)
*D - This is a 'Bias' tire (D is for diagonal-the belts run diagonally from bead to bead or at about 45 degree angles to the center line of the tire.
'R' is for 'Radial' - the belts run radially from bead to bead or at 90 degree angles to the center line)
*13 - This tire fits 13 inch diameter wheels
*C - The load index (also tires can be labeled with a ply rating, typically a "C" load range is equivalent to a "6 ply" rated tire, "B" is a 4 ply and "D" is a 8 ply)

Bias Ply Vs Radial Ply

2011-11-18T12:49:00.000-08:00

At RecStuff.com, we often get the question ‘What’s the difference between radial and bias ply trailer tires?’. Naturally, the next questions tends to be, ‘Which is better?’, or ‘Which should I put on my trailer?’. The below information is meant to clear up the difference between the two, and assist you to make the best decision for your specific application.
It also must be noted that tires designed for cars, light trucks and trucks, are not meant for use on trailers, therefore not suitable for trailer applications. A radial tire meant for a car or truck is not the same tire in functional design as the tire used on a trailer. Please be sure the size specified on your tire’s sidewall starts with an ‘st’.

What is the difference between a radial and bias ply trailer tire?

The main feature that separates the radial trailer tire from the bias ply trailer tire is the tire’s belt construction. The cord material (often nylon and steel) also often differs between the two. The differences here affect many functional aspects of the tire.
A radial trailer tire is constructed with steel belts of the tire running at a 90 degree angle of the tread center line.

A bias ply trailer tire is constructed with nylon belts of the tire running at a 30-45 degree angle of the tread center line.

What are the benefits of choosing the RADIAL trailer tire construction?

Runs Cooler
Steel Belted – Results in tougher overall construction
Longer Tread Life
Wider Footprint

What are the benefits of choosing the BIAS PLY trailer tire construction?

Crosshatch construction provides stronger/tougher sidewalls
Due to the design of the tire’s construction, bias ply want to roll straight as the trailer itself often does
Generally Less Expensive

What is the best choice for my application?

Typically a trailer tire needs replacing due to ‘dry rot’ before the tire’s tread is exhausted. The Department of Transportation (DOT) recommends replacing tires (ALL Tires) at least every six (6) years. The key piece of information here is that the recommendation is based on ‘Years’ rather than ‘Mileage’. Please confirm your tires by checking the manufacturer’s date imprinted on the sidewall of every trailer tire. While we understand that some tires are rated and built for higher mileage, trailer tires are often not mobile, as the trailer doesn’t always come along with you everywhere you drive. The general rule of thumb for mileage you can get out of your trailer tire is about 25,000 miles.
So, if you’re trailer makes those longer trips with you on a regular basis, you will probably benefit from spending the extra money on a radial trailer tire to take advantage of the longer tread life. If your trailer spends a lot of time next to the garage, you might want to save yourself some money by going with a bias ply trailer tire.
We offer both Radial and Bias Ply Trailer Tires in our online store, RecStuff.com, at some of the best prices online. If the information above still leaves you with more questions, please feel free Contact Us or give us a call at (414) 617-5933. We’ll try to help you out as best we can.

How To Determine The Age Of A Trailer Tire

It's easy to identify the age of a tire. All tires sold in the US require a DOT code which is mandated by the U.S Department of Transportation. The DOT code indicates the tire meets all federal standards, these identification numbers are important if the product is recalled. The DOT code begins with letters followed by numbers and letters; this is the plant code identifying the manufacture of the tire. The last four numbers after the plant code represent the week and the year the tire was manufactured.
The Department of Transportation (DOT) recommends replacing all tires at least every six years. When purchasing new trailer tires discuss the vendors product turn over rate, to ensure the product that you are receiving has been recently manufactured. Below is an example of a DOT code that is found on a trailer tire.

Example:

DOT K3AP 4309
K3AP is the plant code identifying the manufacture of this tire
4309 is the week and year the tire was manufactured, this tire would have been manufactured the 43rd week of 2009.
Other numbers are marketing codes are used at the manufacturer's discretion.

Do Trailer Tires and Wheels / Rims Need to be Balanced?

2011-11-18T12:26:00.000-08:00

We often get questions on whether trailer tires need to be mounted AND balanced when being put on a wheel.

Typically trailer tire assemblies are not balanced out of the factory. If you balance your trailer tires and then pull the trailer unloaded for some distance, the trailer will tend to bounce due to the light load and more often then not, throw the weights from the wheels. Every time this occurs, the assembly would need to be ‘re-balanced’.

Along with this, tandem axle trailers tend to throw weights when backing sharply due to the stress put on the mounted assembly, so it becomes almost impossible to keep up with balancing your trailer tire assemblies.

Most people do not feel a difference between balanced trailer tires and non balanced tires. More often than not, the majority of people do not balance their assemblies, but it is left up to the preference of the owner of the trailer.

Our Tire and Wheel Assemblies at RecStuff.com are mounted but not balanced when they ship out of our factory.

The Anatomy of a Trialer Wheel or Rim

2011-11-18T12:13:00.000-08:00

The trailer wheel isn't thought of to be as a 'technical' piece of equipment all the time. While it's functionality is pretty straight forward, there are many critical parts of the wheel that are often overlooked when considering the best option for your application. See below for 'the anatomy of a trailer wheel'.

Wheel Offset - The distance between the wheel centerline and the mounting pad.
Backspace - The distance between the mounting pad and the outer most part of the wheel's drum side.
Wheel Centerline - The absolute center of the wheel.
Bolt Circle Diameter - The diameter of the circle that the bolt holes are drilled on.
Wheel Diameter - The wheel's diameter where the tire's bead mounts and creates a seal.
Mounting Pad - The portion of the wheel that butts up against the hub face.
Drum Side - The side of the wheel facing the trailer drum.
Street Side - The visible side of the wheel when mounted correctly.

The offset of the trailer wheel often is the difference between the wheel working/not working on your trailer. Some wheels are designed to give more space for the trailer's hub. Below is an explanation of the difference between a 'Positive' and 'Negative' offset.

Positive Offset - The wheel's mounting pad is adjusted away from the drum/brake side of the wheel's centerline.
Zero Offset - The wheels mounting pad is in line with the wheel's center line.
Negative Offset - The wheel's mounting pad is adjusted away from the street/wheel side of the wheel's centerline.

The above information can be vital when choosing the correct wheel for your application. Be sure to verify your measurements before you proceed in the replacement of your wheels.
