How To Determine If I have a 15" Wheel with 5 on 4-1/2" or 5 on 5" Bolt Pattern

Question

Question:

I am unsure as to the size rim I need. I have measured according to the website but when I try to match it to a 4.5X15 rim the holes do not line up. Can I send pictures of the rim with measurements and perhaps you can help?

Thanks for the pics Russ.

Based on your pic showing center to center measurement between the two holes being 3", you have a 5 on 5" bolt pattern, and not a 5 on 4-1/2". Since you have a 15" diameter wheel you'd need a wheel such as the # AM20428 which is a 15" wheel with the 5 on 5" bolt pattern.

I'd double check that measurement, as it's kind of hard to judge from a picture.

@Russ # A225R65WS would be the closest option we have for you. It's the correct size wheel (Bolt pattern and diameter), but the tire is a little bigger as 205/75R15 is the smallest 15" tire for a trailer. The 205/70R15 tires you have are not a trailer size.

@SamuelC thank you. I am assuming a 5% aspect ratio difference should have no impact on a tandem trailer with free wheeling axles.

@Russ It should not, as the trailer did not come with those size tires. you're talking about a 3/4" overall difference, so as long as you currently have at least an inch or two between the tires, and about the same between the top of the tire and the fender, you'll be fine.

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

You can add larger wheels and tires to a trailer as long as you have enough room for the larger size. The main clearance issues we find when putting larger tires and wheels on a trailer is from the top of the tire to the fender and from the inside…

Karrier and Loadstar are two different brand names used by Kenda. There's no difference in quality or function between the two brand names. For a ST175/80-13 Radial trailer tire in load range D, I'd recommend part #AM10210 if you're…

Answer 9

The two tire sizes you referenced, 4.80-12 and 5.30-12, both fit 4-inch wide rims, but they differ in their overall diameter. A 4.80-12 tire/wheel when fully inflated will have a diameter of 20-1/2-inches while the 5.30-12 size will be just under…

Hey Medic, so the Kenda ST235/75R15 Radial Off-Road Trailer Tire #KE68JR was designed for off-road traction but it is going to do really well in the wet and snowy conditions. Based on what you are looking for these are going to work well.
