Hey guys I'm new to the site, i have an 89 gt with some mods, I have 17 inch cobra r's on it now and i just bought a set of pro stars off a friend they are 15 x 8 and have 4.5 backspacing, I need to figure out a size drag radial that will fit with no problems with stag shocks and fender lips, also I'm going to order the front pro stars 15 x 4 and am also looking for a good size to run on those, thanks

 

Welcome to CMOC.ca! Good luck with the tires.

 

Welcome to the forum!

 

Street tire, or drag tire, or slick?
And welcome aboard.

 

A very common size for the rear is 275/60/15 but you may want to get the fender lips rolled. I'm not sure for the front though.

 

Im new to welcome

 

Hope you find what you need and I have no doubt it will look great once you have them on

 

4.5" backspacing is going to limit how much tire you can get under there, 5 or 5.5" is more commonly used on the Foxes. I'm thinking that 235/60R15 is going to be about it. On the front, BFG has a 155/80R15 in the Radial T/A line, that would be OK on the 4". If you want something a bit wider, look for a 185/65R15 or 195/65R15, they could be squeezed on to a 4" wheel.
