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

Did I ruin my tire?

I used my cyclops trainer for the first time yesterday and now my back tire is flat, but not meaning deflated. It's flat about 1/4 inch all around from the friction of the trainer. Did I have the tension too tight? If the tire ruined for riding? Should I be looking for a spare wheel to use on the trainer? Lastly, should I be replacing this tire before my Saturday ride?

Thanks,

flatten rear tire is ok to an extent once it is felt while riding i would change it. I have the Continental Hometrainer tire on a spare wheel with a free cassette i got so i don't waste my GP4000 S. Thats the recomended route if you do a lot of trainer miles.

On a side note you probably had the tension a little too high.

Thanks for the advise. I will be using the trainer more for time constraints to get in a workout rather than due to sleet and snow. Looks like I'll be getting a cheap back wheel...

A trainer will cause your rear tire to wear out more quickly. Most people buy an cheap rear wheel and mount their old tires on it for use with their trainers.

If you got a flattened ridge in one session on your traininer, yes, you set the tension too high. The tension should be no more than it takes to keep the tire from slipping when you jerk it with your hand. Any more than this and you'll be going through tires like it's out of style.

The cycleops has a large roller, so if you have it set up properly, your tire should be seeing only slightly more wear than it would with equivalent miles on the road.

It might be that you only noticed the flat ridge now but it was there before? Not criticizing, just asking.

I ride all the time on trainers due to weather, work, etc. I typically go 40-50-60 hours before I see noticeable wear on my normal tires (no "trainer" tires). They get a silver sheen but that's it. I do some hard efforts so the tension is cranked enough to get 1000 watts transferred to the roller.

I have a tire I've used for 3 years or so for training outside and the trainer and it has a noticeable flat bit in the middle of the tread. Still fine for outdoor use though.

hope this helps,

More likely too low, causing the tyre to slide against the flywheel.

Done correctly, a tyre will wear on a functional turbo not much more than it would on the road.

My experience, in helping to run weekly club turbo sessions for people of a very wide ability range, is that more people have trouble with too little deflection on the tyre. Aim for about two to three mm of indention, though your turbo may vary.

Failing that, don't bother with one of the trainer tyres. Use some old worn out tyre. Ask around if you've not gone one to hand. I've got a stash of nearly-worn-out tyres that are just a bit to sketchy for my liking for actual riding, but still are technically ok - they're all waiting to be finished off on the turbo.

I think its too low tension.

Make sure you have enough air in your tire first.

If you have a bunch of little black things below your trainer now, your tension was too low, causing slippage.
