OK to overinflate studded tires?
my not-fat friends who ride Marathon Winter studded tires say they are just as fast on bare pavement as regular tires. I experience a 10% or so slowdown, and I can tell I'm pedaling harder.
I'm wondering whether this is because my extra weight creates more tire drop, thus leading most of the spikes to touch the road whereas skinnier folks only get the center spikes. Marathon Winters are rated for 70psi, and my regular Marathons are OK up to 100. I'm wondering whether I should try pushing the Winters up to 80 or 90...will this damage the tire? I'm guessing not but thought I'd ask around before trying it... |
My MW's aren't as fast as my supremes but that's no prob for me. IMHO overinflation is not a good thing. Just think how much faster you reg tires will feel when the snow is gone.

I used to over inflate tires by up to 10% or so with no ill effects. That being said my Marathon Winters look like the cross tire with studs in them. I wonder if the slowness is due to the more aggressive tread and possibly a softer compound.

Another thing, studded tires can do a lot of damage to bare pavement, which is why they are illegal for cars in many places, so we are coming into the season where, we need to decide when to take the studded tires off. There are a couple of solutions, another bike which doesn't get studded tires, or another set of wheels without studded tires, where so you just swap the wheels rather then the tires. |
