Tire shredding Kurt Kinetic& cyclcops

grom said:

Last spring i noticed my cyclops fluid trainer was shredding my rear tire, i thought it was because the unit was old (7 yrs)it blew it up, it was replaced - lifetime warranty , the new unit same thing so i sold it for fear of blowing it up and purchased a kurt kinetic , i have tried 3 different tires the pro race from last year, a brand new ricorso and a another brand new pro race just to make sure it was not the age of the first tire. anyone have this kind of problem? is there a preferred tire to use on a trainer?

Got a buddy that has the same problem, so he bought a new one and gave me the old one, I have not had that problem, I've used it all year just to warm up for races though, I do not train on it. I think he cranks up the tension way to much, I've seen him do it, I tighten it up some and use the gears for a harder workout. I would suggest emailing the company and ask them. Also make sure the roller is smooth & has no little pits and stuff.

One and a half turns is fine for me for most workouts. If I'm doing a sprint workout, maybe 2.5 turns. Nothing crazy.

Try the least roller pressure possible without slipping. You shouldn't really see any deformation in the tire.

I have a Kurt kinetic trainer and it scalps tires like nobodies business. I've tried varying the contact pressure but there is no change. I use a old wheel with an old tire on my trainer now.

Fluid2 using the recommended 2.5 turns tension and I've had no problems with tires (Schwalbe Stelvio and Conti Ultra 2000). The difference might be that I don't do sprints on the trainer... all my intervals are done in a way that I don't spin the wheel on the roller.

if you use a 28mm tire you won't need to tighten the roller as much because there is more contact surface, i do a lot a maxium intensity workouts and hardly need to tighten it because it doesn't ever slip.

I know I probably tighten it up too much. But even if I tighten it up as much as possible, I still can make it slip. Afraid even to try sprints on it. Been using Bontrager clinchers so will try something else this season.

My preference is to use old, worn-out, beater tires. There's no way I'd buy new race-quality tires to ride on my trainer. When trainer season rolls around, I put a crappy, old tire on my Powertap wheel, and my trainer doesn't even know the difference.

i always used the end of season tire as it was always pretty warnout so even if it shredds it just going to get tossed the smell of burning rubber for a couple of hours cant be good for my health either

The link above is to a UK company, but I would imagine you can get Continental tyres in the US also?
This tyre has been specially formulated for use on turbo trainers. I am still using up an old tyre on the trainer, so I cannot tell you from experience how it performs, but I wanted to make you aware of it.

I have started using the conti home trainer tires recently. they do seem to stay cooler than the others. I do a lot of computrainer climbs in the winter so if it's still in one piece by April it will be a success. Their other tires don't last more than a month or two at best.

It feels like greased snot to the touch - would be hilarious to try and ride it on wet pavement (if you were watching rather than riding).

[font=Century Gothic]If your using a tire thats too hard & the pressure between the tire & roller is too much you will have problems with shredding. Best thing you can do is look for a tire designed for the trainer, ride a 'round' wheel & keep the pressure at the minimum needed to avoid slipping. Both Tacx & Continental make tires for the trainer which will last a long time, improve grip & reduce the sound.[/font]
