i really want 20's, but afraid of the powerloss and MPG loss if any..which from my experience is always happens.

i can get these 20" DIP wheels(D65 in chrome) with tires locally for $1150 out the door. let me know if i should do 18 0r 20's???

 

i would do the 18 for sure that what i ended up getting

 

well the 18's are $935 with tires so i figured for another $215 i can get 20's with tires...really just need some MPG estimates

 

im not sure about the mpg but i know the ride sucks with the 20s real bad, very rough

 

well i have had very low profile tires on 20's on much heavier cars like an 87 Cutlass and a 99 Monte, i never thought 35 series rode bad...ever

 

Mine rides fine with the 20's. It's a little bit more stiff than factory, but it's far from intolerable. I still get 400-450 miles per fill up with the 20's on and that's about 85% highway driving.

Ok, here is the deal! This is only my opinion...and it counts for nothing LOL. If you are going to go off stocks..you gotta go with 20"s. I Have 20" DHP wheels with 225/zr20 90w toyo tires. Go BIG..Go WIDE!!! I lowered it 2'' in the front 2.5'' in the back and have a 100lbs of speaker box in the back, roll the fenders a little, do it yourself..but carefully.The wider tires look great to me, it brings the tires to the edge of the wells. The ride is not bad, but it is not like stock. You have to give a little for the appearence. So, to go safe with the better ride... go 18"s, Todd (Uma)
