How wide would these back tires be (in inches)?

Standard 20-inch wheels are wrapped with Goodyear Eagle F1 Supercar tires in staggered sizes of 285/30 up front and 305/30 at the rear.

12" rear.
11.22" front.

You really don't know how to figure this out on your own?

Go to tirerack.com (or almost any other online tire dealer)

Select Tires > By Size

Select a result to see that tire.

Select "Specs".

That's it.

Or, you can just click here... http://bfy.tw/4ohh

Thanks ZWA. Obviously I can calculate mm to inches but on a GM post they stated the rear tire was 12 1/2 inches wide. Which doesn't figure out. That's why I asked.

Open with that next time?

12.5" is quite realistic for the SECTION width, which is usually wider than the TREAD width, and they mean 2 different things. But, under normal circumstances - people mostly associate the term "tire width", with the tread width, not section.

Which, searching google would have still answered the mail. (Just having some fun, please don't take it personally - but really... google).
