got 20s?
 

What offset are you running with your 20” rims? I have a 5/7 drop right now. I just got my truck back from paint and the 15” aluminums have got to go. I'm looking at running a 35 series tire.

umm 20 on a 5/7 u better make sure before u drop the cash that u can turn wihtou out hitten the frt fender lip i had a 20 on my truck witha 5/7 and wasnt able to turn

Anyone else have this problem? Do I need to bag it first?

well u can but u can go i think 2 or 3 in the frt and be clear but u can always run a weird offset but then u got to worry abotu when u turnin and start to rub on stuff on the inside of the rims

Anybody runnin 20's on a 5/7 drop. If so details please!

Can you turn lock-to-lock with a 5/7 drop right now with your stock 15" rims?
Anyone running the '95(ish) Impala SS 17" rims with a 5/7 drop?

I can currently turn lock-to-lock with my 15x8's. I may not be a full 5" low in front. It could be just 4" or a little over.

I was when mine was running.

I don't have a problem with what I have now. 245/60/15. No rubbing. But with 20s, the overall height will increase. I'm worried it will rub.

your best bet then is to go with a 18"/20" combo 5" backspacing 9.5 " in the rear and 8" 4.5 Backspacing in the front, as long as you stay with 50 series or smaller (ie. 45 40's) you should be fine, but you can not make a full tilt turn, especially at high speed, it will drag on the fender well. I would make sure the suspension is tuned correctly. 5-7 with 20"s all the way around is impossible unless air bagged... :metal:

do you have this combo? Do you have pics?
