Looking for advice on my rear tire replacements and I want to be educated. I have Cooper 295/50r15s now and they are over 10 years old and have very little traction(all they do is spin even at 45 mph just hitting the gas in third(5 speed TKO)) I do not intend on drag racing but the occasional fun on the strip/ street will happen. I have a 1971 GTX with a stroker 500( 585 hp and 620 torque) I drive it about 4000 to 5000 miles a year and avoid rain as much as I can. What do you guys or girls suggest?
