I'm running the Coker redlines on my car. No complaints really other that the "pizza cutter" lines that you get with these tires. I have had them for 8 or 9 years still working fine although I can't say I put much milaege on the car these days... sigh. I use a product called AutoGlym from England to clean grim from the redlines and they come up looking new every time. Dave when I got mine there was a Coker dealer on the mainland and made the purchase very easy.
