I was riding on my trainer tonight and starting feeling something strange with the real wheel. I got off and noticed that the rear tire had bubbled. The tube bubbled and popped the tire from the rim on one side. I took some air out, remounted the tire on the rim and reinflated. 5 minutes later I heard a huge pop and the tube blew out. Why would this happen? I pumped the tires to 110 before getting on the trainer. Maybe too much pressure from the trainer to the tire-cranked it too tight?? I have a Cycleops Fluid 2 if that helps at all.

That's why I use rollers. Was your tire seated properly?

Maybe you had some debris on the tire. I blew out my tire on the trainer that way. I have a small piece of glass that blew out my tire on the trainer

Not related to the trainer. Too much pressure in the tire. You don't need 110 psi to ride on a trainer.

Couple of years ago, I had a front tire blow out while on my rollers. Yeah, I went down.

I went to take my Cervelo off of the trainer last weekend to go for a ride and the back tire was flat, when i changed it i noticed a giant hole in the tube like it blew out pretty bad. Must have happened when i wasn't home. Weird.......

You don't need a lot of tension on the rear tire with the Fluid 2.....doing so can also cause them to leak. Once the tire touches the roller, it only requires 1-2 turns of the knob or so.

I have read elsewhere on BF that the rollers used on trainers can put extra stress on tires compared to use on a flat road. Rear wheel rollers are the one place solid tires make sense to me. Could you have a rear wheel just for the trainer? I am impressed that some people are riding indoors enough to blow tires, we do not need to ride indoors here ( ).

Continental actually makes a "trainer tire" that is much harder than normal road compounds (therefore, not suitable for road riding).

Sounds like the bead failed.

Are you leaving the flywheel of the trainer in contact with the wheel after you're done? The instructions on my 1Up trainer noted that the flywheel can get hot enough to melt/warp the wheel, and thus, lead to a tube blow out, especially with such a high tire psi.

Chopper1

Thanks for the feedback. I am not leaving the flywheel on the trainer, so I do not think that is it. As for debris, we will see. I inspected the tire and did not see anything. What pressure should I have the tire pumped to on a trainer?
