Tires melting on trainer?!?!(7 posts)

Tires melting on trainer?!?!filly
Apr 13, 2003 9:53 PM
Just got a 1up trainer and used it tonight. Unfortunately, I don't have extra wheels, so I used and plan on using my standard bike setup for the trainer as I do on the road. Problem is, my rear tire now looks like it got about 500 miles added to it, and I only used the trainer for about 30 minutes. I even smelled rubber toward the end of my session. The unit got WAY hot, and it really chewed up the tire. Is this tire wear normal? How long do tires last on trainers?

Wow, that sounds really weird to me.

I just got a set of rollers, and I've done about 60km on them. I use a cheapo pair of slick tires on the rollers and these tires haven't even lost their mould lines down the centre of the tire! And you're talking of melting rubber? Sorry...I can't help you, but it really does sound unusual.

Cheers,
Tom.

If your spinning fast with low tire pressure and have nice(soft rubber compound)tires this is not uncommon.I usually have some rubber powder that collects at the rear wheel.If you dont want to spend the money on a training wheelset you could just get a rear wheel and mount a good "roller tire" back there.I would recomend a continental sport 1000.
I now you hate Performance but they sell them for $13.99.

I've owned rollers, a magnetic trainer and a fluid resistance trainer and never expereinced rapid tire wear.

Use a normal tire pressure of 100-110 psi. Most of today's trainers have a spring loaded device that automatically adjusts the pressure against the tire. If you have a manually adjustable model, only apply enough pressure to prevent slippage between the tire and the roller. I've been using a tire that's already seen 2500 miles of road use for that two winters and don't notice any significant wear.

I use tires on the mag trainer that are either worn out or cut so badly that I won't use them on the road. I'm amazed how long they last on the trainer. I suspect you have over-tightened the resistance unit or under-inflated the tire, or both to create that much friction.
Maybe you just dont have the power like me and filly! ; )the bull

Seriously I have noticed that when you use a tire with a soft compound it heats up more! I have slightly smelled rubber with tires like hutchinson carbon comps.They are so soft they even pick small rocks up and make them stick to the tire.
Assuming you have everything adjusted correctly try a tire like I mentioned you literally almost cant wear them out!
TRAINERS WEAR OUT TIRES FASTER!
Also the sweat you create will tear a frame up get a cloth that is made for catching sweat drops and ride with a fan!

I have a 1up that I've been using all winter w/ last season's Axial Pros. I do get a few rubber crumbs over time, but have not seen outrageous tire wear. At one point, though, I found that I was skidding on the floor, which did result in extra wear and tear (both on my legs and on the tires!). Like the others have said, you'll want to check the tire inflation (100-110), with the wheel tension just enough to keep from skidding when you mash it. Couple other things: first, the resistance unit does get hot, and 2) I use mine on the easier resistance curve (ball bearings toward the middle), and find that the resistance from the trainer is substantially harder than on the road, i.e. I had to swallow my pride and ride on the low end of the small chain ring. This makes for plenty of room to go nuts on intervals, however. Good luck!
