The only problem with Diamondback is the same as with Coker. EXPENSIVE TIRES. I have GT Qualifiers on my car with red lines that were applied by a guy who used to do whitewalls and redlines on any tire. They lasted almost 10 years. I think I am going to get a set of 4 Goodyear Integrity thin white line tires for about $280 and put the red lines on myself.
