Michelin Pro3 and trainer + burning rubber?
 

Hello guys, I'm new to the trainer scene but got a Cycleops Magneto (from 2008) on craigslist and I have mounted on my bike the Pro3 from Michelin... I did an aggressive 30 minute interval training this morning and most of it smelled rubbery... I turned the knob so there's enough friction on there to replicate what I feel my gears output on the road.

The tires are inflated to about 110psi and I use the skewer included w/ the trainer. Afterwards I checked my tire and of court it's pretty slick and there's a line of rubber on the trainer's roller. I tried to research this and it appears that the trainer is NOT tight enough or my inflation if off? Any advice would be appreciated :)

Thanks

Honestly best thing to do is buy a cheap spare wheel and use it on the trainer. Either put a trainer tire on the spare rim or just use old worn out tires.

Trainers tend to eat your good tires too fast.

1) Put more pressure in your tires.

2) Put enough force between your roller and your tire so your tire doesn't slip when you accelerate the wheel.

There are two things to this. If you are smelling rubber, it means there is slipping between the tire and the roller. The goal is to eliminate slipping. You do this two ways. First, you inflate the tire as much as you dare. I go to about 115 or 120psi. Then you crank down on the tightening knob until you can jerk the wheel with your hand and not have it slip relative to the roller. Some people try to decrease their tire pressure, apparently with the intent on maximizing friction to the roller. This does trick only works on rough surfaces where the problem is with the tire bouncing on the ground. On smooth surfaces, you want as much pressure on the tire to roller interface as you can, and this is wholly controlled by tire pressure. The more tire pressure you have, the more pressure you can put on the tire with the roller and the more friction you'll get out of the tire.

My Nashbar fluid trainer has no pressure setting for the contact between tire and roller. It is the rider weight that determines this. I weigh 165lb and have never had a problem with tire slippage. I just use normal inflation pressures, around 100 psi.

Michelin pro 3's are really soft tires, couple that with the friction of trainers is asking for a very short tire life.

I had heard this proclaimed almost universally. So when I bought my trainer a couple years ago, I also got a cheap spare wheel and started using an old tire. Problem is, I'm still on the same tire. No unusual wear and lots of life left in it. So...now I've starting using my "good" tires on my Powertap wheel. Still no noticeable wear. They get a little shiny, but that's it.

Trainer is a Kurt Kinetic Rock n Roll. Tires are Hutchinson Fusion tubeless.

FWIW. YMMV.
