Replacing 155r12-76 Automotive Tires on a Trailer  

A trailer wheel measuring 15" in diameter by 4.5" wide is a rather uncommon wheel size as most 15" diameter trailer wheels are either 5" or 6" wide. Unfortunately we do not have a tire suitable for your…

A 155/12 tire will be about 6.1 inches wide. The closest match is a 145/12 at 5.7 inches wide. I have included a link to all of the tires and tire/wheel combos we have in this size. A 155 isn't a trailer tire size (unless it has an ST in…

Typically a 1-3/4 inch outer diameter axle is going to have a 2,000 lb capacity. Based on that and the wheels you have that would be a pretty safe assumption.

Thank you for all of the info! I'd be more than happy to help out. For an axle that meets your specs I recommend going with our etrailer Trailer Axle #e37YR which has the 58" spring-center measurement, a 72" hub-face measurement, has an…

To answer your first question, technically you can put truck wheels on your trailer, there are just a few things you will need to look out for. First, automotive grade wheels tend to have more of an offset than trailer wheels, meaning the center of…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

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…

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 difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

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…

From my research on the Harbor Freight 4x8 folding trailer uses 4.80-12 tires on a 12 inch wheel for the 1195 lb capacity trailer and a 5.30-12 for the 1720 lbs capacity trailer. It is a good idea to check your existing tires to see which size they…
