I'm riding on my first pair of 700c (Mavic Aksium) wheels, 23mm Gatorskins (500 miles on them). When I had Gatorskins on my 27" wheels I never got a flat from glass. However now riding in the same areas I used to I've gotten about 6 flats from glass in the last month plus a thorn that went right through it - just seems like these aren't nearly as robust as the ones on my other wheels.
Was talking to another rider who said he bumped the tire up to 25mm and then 28mm and now doesn't get flats but got them constantly on the 23mms. I was wondering if the width of the tire means thicker tread which would make it more flat resistant. I'm also thinking about going to Armadillos but a friend has them and it really does feel like you're dragging an anchor. Not that I'm a speed demon or weight wienie by any stretch but I am doing a few 145 mile rides and that weight will catch up with me. Then again stopping to fix four flats will probably piss me off too. So I'm wondering if I should get a 25mm or 28 mm rear tire, deal with a flat or more a ride, or bite the bullet and go with Armadillos.
I'm a Clyde at 270 but I keep the tires inflated max and even a bit over (between 130-135).
