Advice on tire size?

gavoci92 · 11-27-2015, 10:53 PM

Hey guys, I was wondering what would be the issues with going with either wider or thicker tires on my current set up: Running 8.5/9.5 with 235/40 and 265/35.

If I go thicker, with 235/45 and 265/40, what would be the issues?

or If I go with wider, 245/40 and 275/35?

Any issues such as rubbing, loss of comfortability, or steering issues?

From my point and experience;
Thicker give more comfort, but your rolling radius has increased,
wider, give more stability, less performance due to friction area, steering might be slightly harder
rubbing is all about the wheel offset more than tire thickness I guess, its better to measure the clearance of your current setup and see if you have room

Wheel specs would help.

Thick usually means more rubbing.

This. Running a taller tire will not only increase your rolling diameters but it will also increase the likelihood of rubbing. If you went with a taller sidewall, you would be about .46" taller in front and .52" taller in the rear.
