Front and Rear Wheel Sizes

Hello all, I'm looking to invest in some new wheels for my '10 Challenger RT, link here... I have an option to buy 20x9's for the front and 20x10's for the rear, but I do not know if this is what I should go for. I am running 245/45's on front and rear, and I plan on using them on the new wheels as well. My question is, are the stock 20" wheels the same size front and rear, and should I save some money by buying all four 20x9's, or go for the 20x10 rear wheels?

The 10" is too wide for that 245.

The point of having two different widths is to have a staggered look.

I have 20", front is a 9" rear is 10" have 275/40 front and 315/35 rear.

So I'm assuming that the stock wheels are probably 20x9's, front and rear?

If they are stock R/T wheels then they should be 20 x 8.

I have 245/45-20s on the front and 275/40-20s on the rear of my 2009 SRT, equipped with 9" wide wheels. They look great (see attached photo). Why not go for this staggered "old school" look?

Also, if you are in the market for an excellent, reasonably priced and long-wearing all-season tire, you should consider the Cooper Zeon RS3-G1. I have them and they perform great.

OK, so knowing now that I'm moving from 20x8's to 20x9's, AND keeping the same 245/45 tires, will this cause any noticeable issues such as throwing off my speedo, changing my ride height, or rubbing in the front fender?

No. The 9" is the widest you should go with 245/45 though. The height will only change slightly, not noticeable, and no issue with rubbing etc. You can get 275/40's on there when you need tires
