Going up to 20s

[jcevans7]

I have a 2003 denali wanted to know if I could put on 20s. As long as the bolt pattern is correct it should be good? Right.

The speedo will have to be reprogrammed anything else I should know or look into.

Yes... just when you go up in wheel size make sure your overall tire size is the same.

thanks. rim is bigger but OAL is the same.

You shouldnt need to reprogram the speedo if staying with tires with same diameter even if they were taller it would only effect the speedo by 1-2 mph, try gauging it with a gps you'll see there is little difference

[jcevans7]

Same size in over all length. Maybe actually faster proven no scientific data.

read the same OAL, im previous posts.
Was directed more to the extra weight of the 20's.
Mine are heavy as hell. almost need a 10 ton crane to move them around.
