The Continental Hometrainer tire is specifically made for indoor use on rollers and trainers. Thanks to the special 'cold-running' compound, the Hometrainer doesn't experience the heat buildup of a road tire, nor does it suffer the tread separation that the road tire is prone to under the special loads occurring when in cycling and braking on the roller's revolving drums.
This tire will increase the life of the trainer and roller drums as well as the rim due to the lower heat buildup. Due to its's special indoor compound, the Hometrainer is not suitable for on road use.
I give this a solid three stars since I've had two very different experiences with this tire. Over a year ago, I'd read about people shredding trainer specific tires and heard that the Conti was super solid. So I bought two to use on my rollers. I rode the heck out of them trying to prepare for a good season. Did so again this winter and they look barely used after 60 hours. I recently got another when my girlfriend needed a trainer tire. She's now telling me it's shredding off bits of rubber and looks like it won't last much longer. She's probably used it 4 hours. So I guess it's a great tire if you get one from the right batch. Oh, and they are a serious pain to mount. Had to use metal tire levers and have punctured the tubes about four times. Recommend a dedicated wheel if you have one.
Cons: Doesn't last long
I RIDE ROLLERS OVER 5,000 MILES PER YEAR. IVE EXPERIENCED ALL SORTS OF TIRE FAILURES USING CONVENTIONAL ROAD TIRES ON ROLLERS. USUALLY I WOULD DESTROY AT LEAST 5 TIRES PER YEAR JUST ON MY DEDICATED "ROLLER WHEEL". AS SOON AS I FOUND OUT ABOUT THIS TIRE I ORDERED ONE AND HAVE PUT OVER 5,000 MILES ON IT. IT HAS PERFORMED PERFECTLY: NO SEPERATION, NO BUBBLES INSIDE THE CARCASS, NO DESTORTIONS OF ANY TYPE. I HIGHLY RECOMMEND THIS TIRE. IT SOLVED A NAGGING PROBLEM FOR ME!
