Right now Im running 225-35-19s. Becuase of my widebody Ill be pushing the wheels out about 1/2"-3/4". My rims actually stick out a fuzz further than the tire. Wondering how much of a diffrence a 245-30 will be from 225-35. According to WW's tire diameter prgram the speed difference is only .4% which is aboutt he smallest difference Ive ever seen between 2 different sizes. I also dont want the tires to bulge out over the rims that much.
