Recommended ST205/75R15 Tires for Boat Trailer and Determining Bolt Pattern Needed

Updated 10/18/2017 | Published 10/17/2017

Question:

I need to replace both of my trailer tires and rims. It is a 2008 Sun Tracker Fishing Barge with STP205/75R15, but I am having difficulty determining the rim size bolt pattern. It is a single axle trailer. Any help would be greatly appreciated.

We have a large selection of trailer tire and wheels available in the ST205/75R15 size you are needing.

Most likely the wheels on your trailer have 5 bolts. In order to determine the bolt pattern, you will just need to measure from the center of one lug to a point halfway between the two lugs directly opposite on the bolt circle. This measurement will give you the bolt pattern. I have also attached an article that explains this in a bit more detail that you can check out.

If you happen to have a 5 on 4-1/2 inch bolt pattern, which is the most common pattern for your tire size, I highly recommend the Westlake ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel - 5 on 4-1/2 - Load Range D
Item # LHAW121. This radial tire features a 2,150 pound maximum load at 65 psi and is mounted to a 15 inch steel. This tire and wheel combo also comes with a 5-Year warranty on tire and a 1-Year on the wheel.

I have attached a link that will take you to our available selection of ST205/75R15 tire and wheel combos that you can also look through if needed. If you happen to have a different bolt pattern, you can use the facets on the left side of the page to filter between the different options.
