I like the look of a tire around the stock height, between 29-32" tall. You could go to a 32.2" tall 275/75 16 with a 4.10 swap and have the same result as a 3.42 with a 27" tire(see below) (3rd gear cause its a 1:1).

3.43 + 27" @ 75mph = 3200 rpm in 3rd
3.73 + 27" @ 75mph = 3480 rpm in 3rd

VS.

3.43 + 30" @ 75mph = 2880 rpm in 3rd
3.73 + 30" @ 75mph = 3130 rpm in 3rd
4.10 + 30" @ 75mph = 3445 rpm in 3rd

VS.

3.43 + 32.2" @ 75mph = 2685 rpm in 3rd
3.73 + 32.2" @ 75mph = 2920 rpm in 3rd
4.10 + 32.2" @ 75mph = 3210 rpm in 3rd

a little confused!! so you are saying if I have a 3.42 with some 27" is will perform like if I had a 4.10 gear??? sorry still trying to learn all this readings...

A 32.2" tall 275/75/16 with a 4.10 gear Is the same as a 27" tall 255/55/16 with 3.42 gear as far as Engine RPM

3.43 + 27.0" @ 75mph = 3200 rpm in 3rd
4.10 + 32.2" @ 75mph = 3210 rpm in 3rd

Know what I'm sayin?
