I know it’s slightly too big and the front are 215 I’ve seen a couple of picture of Sierra track cars that look like they are running a 45 profile with 17” wheels but I don’t know what arch work they have had done and the trouble is I want a tire like r888 or ns2r and they only seem to do them in a 205 40 17 and my rims are 7.5j so 205 is abit stretched which i don’t like but I did see a
sierra on here with 19” tsw pace wheels I think I’m just going to have to fit them and see what’s the biggest thing is when I do put my foot down being a 2wd the rear is really going to kick down on the wheels
