Which tire size - 205/75R15 or 225/75R15

I'm looking to upgrade my TT tires and wheels from 14" to 15" and am undecided on whether to get 205 or 225 (75R15's). In my case I have ample room for either size. I know the 225's are rated for a higher load capacity. Is there anything I should consider as to highway performance, tire flexing, heat, turn radius problems, etc?

Also, with the 225's I have the option of load range D or E. Will LR E tires give too hard a ride? Other considerations?

Thanks guys!!
  • I have good luck with 225 75R 15 E tires and recommend at least E's.

    However, if you have plenty of room and are going to up size your rims, I would suggest going with 16". Adds many more tire possibility's, including several Light Truck tires.
  • If room allows, and the rims are rated for the higher air pressure, I would probably go with the 225's in the next higher load range myself. You can look on the backside of the rim, possibly on one of the spokes for a weight rating. The tire with the comparable weight rating will be the highest you want to go.

    You will have a slightly higher rolling resistance, but at ~10mpg regardless the difference probably won't even be noticeable!!!

    Good luck!!!
