I BOUGHT A SET OF DUNLOP GT501 TIRES THAT SPLIT. I CALL THE MANAGER AT THE CYCLE GEAR STORE WHERE I PURCHASED THEM AND HE SAID UNLESS I BOUGHT THE PROTECTION PROGRAM THERE IS NATHING HE COULD DO BECOUSE THEY WERE ALMOST A YEAR OLD. SO I CALL DUNLOP AND WAS TOLD THIS IS NOT TRUE, THERE AI A 6 YEAR WARRENTY AND I SHOULD TAKE THEM BACK. SO I DID AND TOLD THEM WHAT DUNLOP SAID BUT STILL HE SAID THERE IS NOTHING HE COULD DO BUT DEAL WITH DUNLOP ON MY OWN. I CALL DUNLOP AGAIN TO SEE IF I COULD SEND THE TIRE BACK TO THEM TO FIND OUT WHY IT SPLIT AND WAS TOLD I HAD TO DEAL WITH CYCLE GEAR. ON CYCLE GEARS WEB SITE IT STSTES THAT IF YOU ARE NOT 100% SATIFIED WITH THE PRODUCT THEY WILL NOT MAKE YOU DEAL WITH THE MANUFACTURER. DISAPPOINTED WITH CYCLE GEAR.
