Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Trainer is ruining my tire!

The trainer is causing my rear tire to wear down. The bike shop says it's inevitable, but I thought maybe someone here has come up with a clever way to avoid this problem. Any suggestions?

Also, is it safe to ride on the road on a tire that has been worn down from the trainer?

Do you have an extra rear wheel? If so, you can either use a trainer-specific tire or an old tire.

The only clever way of preventing tire wear on the trainer is to take your bike off of the trainer and ride it outside, where asphalt, grit, and glass will contribute to the wearing down of the rubber.

Anyway, the tire's worn when it's "squared off" and getting thin, and definitely worn when the cord shows through. At that point, it's definitely unsafe to ride outside.

always use old tires for the trainer if thats all you ride. Or just simply kill one set for trainer and one for the road. I don't know how much you like to remove tires.

+1

I save up my old tires for the trainer....I also have an older set of wheels that I use on the trainer. I keep the better wheels with the good tires ready for action if the weather clears enough to pull the old bike off the trainer for an outside ride.

Alternatively you could remove the resistance unit from your trainer. That should save on tire wear.

A lot of times I think people have the roller of the trainer pushed up too tight against the tire. This causes the sidewall to flex excessively and makes the tread hot. There are several reports that say their tire is hot to the touch after a trainer session. This shouldn't happen. To keep that from happening, I've found that if you inflate the tire up to 110 psi or so and tighten the roller against the wheel just enough that the wheel won't slip, you'll keep wear to a minimum.

I honestly don't see how the tire can wear that much faster than on the road. The contact patch is somewhat smaller, so the tire sidewall will deflect a bit more, but you'd think you could solve most of this problem by inflating the tire to a bit higher psi. Besides, all the grit you encounter on the road should more than make up for the decrease in contact patch size. The roller is smooth aluminum, so any wear would only be a factor of tire heating. I dunno. I'm kinda experimenting with this this season.

Regardless, if you adjust the tire pressure and the amount you tighten the roller against the wheel so that the tire doesn't get warm, your tire should last a fairly long time - theoretically about as long as riding the same number of miles on the road.

I use the Conti trainer tire, works great and doesn't destroy my ProRace2's. Only thing I hate about it is how difficult it is to mount, but I don't anticipate getting any flats while riding my trainer.

I picked mine up on eBay for $20 2 yrs ago.
