20x9 with 275/40-20 on a stock RS?

[Master Shake]

New user here!

I want to upgrade to 20's from the stock 18's. Most places are selling 20x8.5 with an option for 20x9 or 20x10 for the rear, if you want to go with staggerd.

My question is can I use the 20x9 on all four wheels? Or will it cause any type of rubbing or caliper interference, etc.?

The wheels I am looking at are the Sport Muscle CM5 chrome -- which is very close to the OEM SS chrome wheels. The offsets are +40mm and I would use 275/40-20 tires on them.

Thanks!

Edit: Sorry, Not RS. :-) I have a base model LS.

The 9 inch will fit. As long as you have the right offesets obviously and you stay close to overall tire diameter. No problem. The set-up you are talking about should work just fine.

But there are no stock 18s. Only 19s.

Uh... LS and 1LT both come with 18x7.5 wheels stock.

Shake, for starters, WELCOME!! and YES you can. the stock 20"s are 9" wide and have a 40 mm offset. you can EASLY run the REARS all thge way around and put 275's on all four corners......there are quite a few of us have done that and they fit and work fine. I too have a LT and I am running that combo.
