You may not have to go to a fat tire. If you are running "around 100#"
on a 406x28 Stelvio I think you are borderline underinflated. I
recommend keeping that tire at 120PSI and no less than 110PSI. The
Gp's I keep at 120PSI, no less than 110PSI. My experience with
Stelvios indicates that they cut easily, both on the tread and
sidewall. I have even had 2 of the folding 406X28 Stelvios have belts
separate internally causing visible warping of the tire. On the rear I
have stopped using the Stelvios. I have had good look with a heavier
Conti Grand Prix 559X25 (26X1). I ran a 559X32 Primo racer for 2600
miles with only one flat and retired it after 4 flats in the last 200
miles for a total of 2800 miles. On a T-Bone I am running a Michelin
Ironman 700x25 (110PSI)for 1500 miles and only one flat. In the last
6,000 miles I have had 8 flats, I think. I have never considered going
to fat tires because of flats. Try a different skinny tire and keep it
inflated to the recommended max PSI. Good luck.
I am looking for a different 406X28 or 406 X25 tire. The question I
have is: What other 406X25 or 406X28 tires are people using?
