I am looking for a tire recommendation. I recently bought a 1998 SS SLP. I have the original rims. On the car right now are Corvette wheels. Fronts are 275/40 R17 Cooper zeon rs3-a, the rears are 275/35 ZR18 Goodyear Eagles. I would like to get a softer tire to calm the ride down. I live in Rhode Island where the roads are not great. Any suggestions for a tire with a softer ride? Thank you very much.
