Mine is 3 tenths slower with Centerline Lexi's and 285/50/20's than it is with my Escalade wheels and 275/55/17's. The 20's are a bit taller too, and reduce my 3.42 gear even smaller. I've been 14.5x on motor on Escalades, and 14.8x on the 20's.

 

I didn't notice a loss with my 20" chrome SS replicas. I did install a HPP3 at the same time so I've never ran them on the stock tune. I know one thing for sure though, they don't cut down on the spinning at all! They're nice to have and they look amazing but on my next truck I'll buy some 17" Boyd Coddingtons and slap some drag radials on em' and drive it everyday, I think it looks just as good..

 

I my self run 20" in the summer. In the winter we get enough snow and my Z rated Bridgestones are **** poor. I also notice about a .5 sec slower E.T.s, Just wanted some input from others. Thank you guys for all the replys. I agree they do look way better and handle 100X better, But when it comes to smokin a car in a street race I can live with the way the stockers look from time to time, for a .5 sec drop in E.T., "thats about two car lengths".

 

I run on 20's when i just driving around town, but i put my drag tires on 18's and i dont feel a difference besides a little when im starting and stoping. but i think the looks are worth it.
