Tire wear, worse on trainer or rollers?(6 posts)

Tire wear, worse on trainer or rollers?regulajo

I've seen on this board how tires wear very fast on trainers, is this the same with rollers. Does anyone have experience with more or less wear? Thanks.

Well...trainer only contacts the rear wheel one time, while rollers contact the front wheel once(on some twice) and rear twice. Seems like rollers would wear them faster, but I don't have a trainer and don't use my rollers that often.

The trainer will be much harder on tires than the rollers. It is not the number of contact points, but rather the force dissipated through the contact points, the angle between the contact surface and the tires and the resulting amount of slippage between the contact points and the tire. While the force dissipation through the rollers and the trainer would be the same (if you're working just as hard) the trainer has sigificantly more slippage between tire and contact point. Trainers are essentially abrading the tire, all the more so if you don't have enough pressure on the tire. You'll find much more wear on a trainer than on rollers.

trainers force the contact pressure to be greater with the adjustment. With rollers it is just your weight and the bikes at the contact points, trainers add that to the pressure added when adjusting the contact at setup.
Well, maybe not COMPLETELY wrong ...Allez Rouge

I agree that a trainer will wear the REAR tire more than rollers. But with a trainer, the wear on the FRONT tire is zero. So a better question might be, will a trainer wear out a rear tire twice as fast as rollers would wear out both the front and rear tires? IOW, which device will give you the higher tire bill, overall?

(I suspect it is still a trainer, even though only the rear tire wears.)

My observation from experience:

The resistance trainer will wear tires much faster than the rollers, and probably wear them out faster than riding on the road, too! Rollers cause very little wear on tires.
