Inflating tires below the recommended minimum PSI pressure

    Hello,

    Last fall I purchased a pair of Specialized Armadillo 700x25mm tires. Their PSI range is 110 to 125. Really good tires, works great of paved road and packed dirt roads.

    But since their minimum PSI is 110, it shakes way too much when riding on a loose gravel road section. Of course I slow down considerably when riding in loose gravel/dirt, but even when riding slowly the ride is still way too shaky.

    Now, what if I inflate them below 110 PSI? Something like 95 at the front and 100 at the rear.

    Is that dangerous? Can they wear down in a way that they will get fragile or unstable?

    Thanks.

    I run Vredestein Fortezza Tricomp 23mm at 90/95 and Vittoria Open Pave 25mm + Hutchinson Fusion 3 23mm (tubeless) between 80/85 and 85/90 – never had an off moment as far as tyre integrity goes, the Open Paves could probably go a fair bit lower if the surface warranted it.

    Yes, I like them. They are wearing well, even through the winter. There is a new version with better puncture resistance.

    Are you happy with your Schwalbe Durano?

    Do you sometimes go on dirt roads?

    As long as the tyre doesn’t bulge too much at the bottom I doubt the tyre would roll off the rim. I use Schwalbe Durano 25mm and run about 95-100 psi. Your other option is go 28 or 32mm if your frame allows.
