This question has probably been posed before but I thought I would ask anyway. I am having real problems cutting the sidewalls of my tires. I have cut Schwalbe Ultremo ZX, Michelin ProRace3, Specialized Turbo, Mondo, and All Condition. I have had Conti GP 4000 S which I think did a bit better, but I think I cut those too. In fact, it is hard to remember all of the tires I have cut. I ride the same roads as Xela and he gets thousands of miles on tires. If I get 3 months (700 to 1000 miles) that's a long time for me.
I am 6 1 or 2 and weight about 220. I was thinking of going with a 25C tire. An article on Bike Radar said rolling resistance on a 25C is less than 23C anyway. I know of the Continental Gatorskins and some others. I am reluctant to speed 65 bucks a tire unless I am absolutely sure the thing is gonna make it. Any other suggestions? Any thoughts on how much tire weight affects things? 23C v 25C? Thanks for any input.
I was hoping maybe his tire guage was reading low and that maybe he was actually underinflating the tires. But I checked it against mine and that doesn't appear to be the case.
I'm thinking maybe the sidewalls on the tires he has chosen in the past is not stiff enough for a 220 lb rider resulting in more sidewall contact with the road. I do know that the Pro Race 3 pressure chart only shows weights up to 176 lbs and says to run 116 psi for greater than that.
What are some of the bigger roadies around here running?
I've close to 220 (just over) and have been experimenting with pressures due to my weight gain from surgery. I'm running Vittoria Zaffiro Pro tires @ 120 psi without incident.
I actually just picked up a set of Michelin 3s, now I'm doubting my purchase! I intend on dropping the weight quickly so it may not be an issue.
I think that if he's routinely breaking sidewalls that it may be a mechanical issue (rim wall deficienies/deformities?) leading to failure or maybe a repeated error in tire mounting or tube size selection/disconnect in sizing?
I am running a custom built set of HED wheels that are pretty much the same as the Ardennes. The wider wheels. Brake pads seem to be fine. I really think the problem is that I just hit chunks of gravel, etc. Of course the ideal solution is to not hit that stuff but.......... A local LBS just recommended the Vittoria Rubino Pro Tech. I went to their website and they also make a similar tire, the Zaffiro Pro Tech. Both have extra sidewall protection like the Conti Gatorskins. Thanks for the input.
I'm 6' and when I first started riding, I was over 220 lbs. I was riding with the Specialized Mondo tires at 120 psi and didn't have a problem.

no one has mentioned how many spokes for 200lb plus riders should have?
i thought it would 32/36 spokes. and what about the spokes gauge 14?
i wgt 195 an my bike,(tire forte mtero k 700x35c), has 36 spoke/14 g spokes and i'm glad it has them.
the bike paths around my area suffers froms lots of speed bump alias tree roots.
hit them at 15+mph has quite a jolt.
One last thing about the Zaffiro Pro tires. The sidewall patch/label is actually a separate piece of rubber bonded to the sidewall, rather than just printed. Mine are starting to peel away. At first I thought I had sidewall cracking, but it was just the patch/label peeling away.
