I have the TV in the driveway with a TT spare tire in the back so I went out and measured both tires.
TV 245/75R15 (Load Range E) - 29 1/2" high x 10.0" wide
TT 225/75R15 (Load Range C_ - 27 3/4" high x 8.5" wide
I've never up-sized on at TT before (have on several trucks), but I don't think there is anything that would impede a little more witdh (no wheel wells),
and 1 3/4" more height may be possible. I'll have to check the TT (at storage lot).
Any thoughts on up-sizing 225 (past 235) to 245 on TT.
Probably will be 235, but trying to consider everything if I can get an E rated 245.
You have to remember your only gaining half of the overall tire height in your wheel well. Also, your tire choices really are limited by your wheel lug pattern, wheither you have 5 lug or 6 lug wheels. If you have 6 lug I would look at maybe going to 16" tires and wheels as I've never heard anyone say oh I think I have too much tire for my trailer. As for my experience, I'm not afraid of ST tires as the 65mph speed limit for them doesn't bother me one bit. I think most people upgrade to LT tires so they can drive faster towing. I upgraded both my 5th wheels from 15" to 16" wheels with Maaxis ST tires.
