how much power loss will i experience going from 285's to 315's on an 07 H-3? thanks

 

A pretty good amount? Noticable off the line, Eway on ramps, and passing.

I have pleanty of friends running 35s, and they do not seem to be bothered by it too much, we all know H3 aren't fast any way.

IMHO, I would run 305s on the I5s and 315s only on the Alphas, but that is just me. With 33" tires, you get the best of both worlds.. a compromise sure, but isn't it always. As much as we like to go wheeling, most of our miles are logged on road.

 

Thanks, i think 33,s are enough for the 3.7 to handle. 315,s look good but like you said H-3,s werent overpowered.
