Question:

I currently have 14inch wheels with on my 2012 tandem axle trailer. Tire size is ST20575R14. my rim size is 5 on 4 1/2. 5 bolt pattern. Question is: can I upgrade to an ST22575R15 D range as long as I have the clearance which I do? Please let me know.

Expert Reply:

Yes, you can switch from 205/75-14 tires to 225/75-15 tires if you have the clearance all around the existing tires. You will also need to replace the wheels though because a 15 inch tire will not fit on a 14 inch wheel. I recommend going with radial tires since they track better and run cooler than bias ply.

For a 225/75-15 radial load range D tire and wheel combo with 5 on 4-1/2 bolt pattern I recommend # AM32545.

Please note that going to a higher capacity tire does not increase the capacity of the trailer. I have included a link to our help article on trailer tires for you.
