This last week I swapped my 08 2wd RCSB to AWD. I'm looking for something lighter and shorter (to gear me down a bit). My current wheel and tire combo weighs in at 75 lbs. I'd like to shed 20 lbs or so off each corner.


Has anyone ran any of the following sizes:

255/45/20
255/55/18

They both are about 29" tall and about 9" wide. Also they are quite a bit lighter than the 285/50/20 tire I am running now.

Does anyone the weight of GMT900 18" Z71 wheels and hybrid wheels? I know Centerlines can weigh in the low to mid 20s for 18" and 20".

 

My centerline 18's with 255/55/18 weighed 55lb 285/50/18 58lb. stock aluminum 17 with 275/60/17 55lb.

centerline 20's depending on tire size/brand can be 50-60lbs

 

The 18" Z71 wheels weigh about 30lbs.

 

Thanks.

Any one have any hard data on 1/4 mile performance when they swapped to a light weight set of wheels?

 

on my old truck i could knock .4 off my 1/4 mile time by taking my chrome SS 20s off and going to a smaller lighter stock rim/tire combo.

 

My centerline 20's with a 265/50/20 tire weigh 55lbs

 

I just had some 255/55/18's mounted up on Escalade 18s (54 LB combo). I'd love to see .4 off my 1/4 mile time. They knocked 20lbs off per wheel. I soon find out what difference it makes.

 

Factory 17" CC steelie with 265/70/17 Michelin LTX weighs 73lbs

 

Well I weighed them on a better scale. 58.8 lbs. Still 16 lbs a wheel lighter. It also knocked at least two tenths off my quarter time (could be more today was super hot).
