Yes they will but only certain types of 13" rims. I got lucky finding these.
Be aware that most 13" wheels will be around 5.5" wide. If your running something like an 8" circuit slick, they really wont work to their potential and will wear terribly. Ive tried running the kumho F3 slicks 13x8's and they didnt sit very well. If their drag slicks than it wont matter as much.
I usually run toyo R888 GG's in 205x60x13. They bulge a bit but they have a stiff sidewall.
If you got the coin, there are many companies that make race wheels in 13" sizes with better widths and clear GT calipers. Youll also find 13" motorsport tires are significantly cheaper.
