265/70R16's work on a 2003 Z71?

Stock tire size is 265/75R16, so I would be dropping a little in height. Anycomments good or bad?

I know it would affect my speedometer and so forth, but could I just get Allen to adjust my tune?

They will work fine. Allen can adjust your speedo for you. He did mine when I put 4.10s and 20s on my truck.

It will also have the effect of having a lower gear....your 3.73 is going work like a 3.85.

A small amount of increased multiplication of your engines power. A very minor increase in rpm. Kind of the same effect of swapping gears from 3.90 to 4.10s.

i just put 255/65r16 on they look a little small but the 265/70r16 should look just fine. your speedo should not be that far off if you old size is close to the size u will be runnin

I&#39;m running 265/60&#39;s and they do just fine.
