the reason i wanted this information was to determine if the 20's slow down the acceleration and decrease fuel economy. while fuel economy isnt a huge concern because it is a 5000lb brick with a 5.7L in it im just trying to take everything into consideration.
^^ I would like to know too. I think for this very reason I will not get 22's...and would be very interested to know how much damage 20" srt reps would do to the performance/fuel when compared to the stock 17"s?? + rep for first ACCURATE answer
^^ true that...BUT let's assume that there are no other variables...overall diameter of the 20" tire is close to stock 17"s (less than 3% lets say)...anyone know the exact weight difference? Either SRT's or reps will work, IIRC the reps are 1 pound heavier than the stock SRT's?
and according to tirerack the 245/65-17 sra is 32 lbs which puts the wheel at 28lbs.
have you ever heard of people running 20x9's on all 4 corners? if i go this route i think id like to have the 255's on all corners and that would be a little narrow for a 10" rim.
