Does anyone know the recommended tire size for the Champion Motorsport RG5 rims? I have an opportunity to purchase these from my bosses best friend for kinda cheap....casual number thrown out to me was "a couple thousand". I know they need new rear tires, since last I saw them, they were very worn out. Thanks everyone for any thoughts on this.

 

I had the RG 19s and 97s with 295s. The edge if the rear lip is very exposed so I thing 315s will easily fit.
