Changing tire size and removing body lift?

Thanks man. I'd rather go to a CHEAPER tire to buy (and less maintenance) rather than putting MORE money into re-gearing. I think 265/75/16 is stock size for our trucks. I think my dad went 285 on his.

I think 265/75/16s sound good. They are 31.6" in diameter. My OEM tires are about 32" (on 18" rims). By using the larger 34.6" tires, you are losing about 10% of the effective force your engine is capable of exerting on the road to get you moving and keep you moving.

I just measured my tires and they are 33.5" and my dads 285-75-16 tires are 32". Why does the height of the tire change when the only difference in the tire size (as indicated by the side wall) is the width of the wheel.

You are correct in that the difference in the sidewall size is the width of the wheel, but the second number denotes the height of the side wall as a percentage of the width, so even though the number is the same, the sidewall is larger because the tire is wider.
Does that make more sense now?

Hahaha....Yes it does. I found the formulas to figure everything up on tirerack.com. I think by trying to set a world standard they made it confusing for some people...like me

Thanks again
