Best Tire for Cobblestones?(5 posts)

Anyone have a good recommendation for a tire to handle a cobblestone course? I've got a TT coming up that will include much of the course on the 'stones and want to make sure I don't blow out in the first 100yds.

Any thoughts on PSI settings would be great too.

Try 28 or 32 @ 75-90 psi

I just don't do cobbles enough to tell.

As for tires, obviously the 150 gram 20mm ultralights aren't going to cut it.
If these are true cobbles, meaning there's gaps between, but no sharp edges, I'd recommend a 23mm reasonably tough tire. Something like a Panaracer Stradius Pro or Extreme - I've had no problems with my Pros, and I know I've nailed broken glass and plenty of gravel. They'll take 150 psi, as well, though I wouldn't recommend it. Depending on your weight, I'd say 120-130 is plenty.
If we're talking really rough, like pave type riding, with sharp stone edges or rocks set in the dirt, then 25mm tires are called for. The Axial Pro 25 is very good, comfortable and fairly damage resistant. Pressures around 90 psi should prevent pinch-flats. If it rains, drop that to 85 or even 80 if you're light. These are wide treads, but they need to spread out a little for wet traction - they were made for Paris-Roubaix, after all.
Also, make sure your bike position is comfortable, and consider a little extra padding for your saddle. Personally, I'm still swapping things around on my TT bike, but right now, I have a WTB SST-K on there, and it's ugly, but very comfy in a tuck, and padded enough to smooth out the nasty roads around here (central PA). If you can, you might want to spread the arm-rests and perhaps even the aerobars, for more stability while hitting the bumps. It'll make you less aero, yes, but you'd lose more time in a crash.
Good luck out there, and like I said, if it rains, be careful. Not much slicker than a wet rock to a skinny tire.
