So the junkyard has a huge stack of slicks and I was wondering if they would fit on my car. Not having a clue as to how to read drag slick sizes, I come here for help. The sidewall says 22.0x7.0-13. Will this fit on the oem stock rims(GSL)? Thanks.

 

Stock Tire Size = 185/70-13 (http://www.tirerack.com)

The slicks your looking at are a little small, but, YES they will fit!
22.0 x 7.0-13 = 178/64/13

You could go up to 23.2 x 7.3-13 or probably a little larger if clearance permits.

I believe it's: Outside Diameter x Width - inside diameter. I can't help you on whether they'd fit under your car, but they *should* fit your wheels, albeit with some deformation to the contact patch.
