I want to buy new wheels.

[Mityguy]

I have a LS camaro running 18 x 8 I believe, oddly enough thats kind of a tough wheel to find. But that doesn't really matter I want some bigger wheels anyhow. If I get 20 x 10; can I just get tires mounted and balanced and aligned? OR do I have go through an expensive process of something else?

You would just buy the wheels and tires you want and put them on the car. The question is, will the dealer be able to reprogram your speedometer for the new size wheels and tires or do you have to get an after market tuner to do it.

If you maintain the same ratio of size you dont need to do any speedometer recalculation.

Use this to figure out the size you can run.

One of the decent things GM did engineering wise with these cars is that no matter what trim level Camaro you bought, they all have the same diameter wheels which I believe is 27" so the 18" rims and tires are just as big around as the 20" rims and tires
