Lack of power with 20's

[splinter]

My 20"s rock.

You're good bro!

Heavy wheels suck and light weight 20's are expensive.
Either change gears, add a good amount of power, as in over 50tq to wheels.
Or just deal with it.

guess no one got the explanation about rolling resitance
all i know is my tahoe had 20s and now my suburban has the stock rims and the ride quality is so much better in the burban ill never get rims larger then 18s 20s and up yer ride quality turns to crap ive also noticed my alignment doesnt get outta wack so fast like it did in the thaoe

I had aftermarket 20's with Goodyear LS tires, went down to OEM 18's with Cooper AT's, new tires ended up being 11lbs heavier each than the old tires. Didn't really feel much difference

Mine seemed the same. Same tire size also
