Continental

Long time GP, GP 4000, and now GP 5000 TR tire user. For the weight, these are the most durable tires, long wearing and great grip. I'm 185 lbs and ride in the PNW, often crummy road surfaces and sometimes wet. I'm running 700x30 on 25mm internal width rims at 58/62 psi. These are still comfortable (I down sized from 32s) but, handle better on high speed turns, as I don't feel the tire flexing between the road and rim. The right tire, rim and PSI is crucial, and these are my numbers. I've ridden Schwalbe G1, Vredestein, Maxxis High Road, and top end Vittoria tires, but always go back to Continental GPs. Great tire, great ride.

Probably the best tire I've used in the 30+ years of cycling. I've used Michelin for years and turned to Conti's after recommendations. Going from tubed to tubeless was the next best choice in the evolution of the tire. These Conti GP 500 AS TR have been a welcome change and have performed well over 7000 miles of use. I'm getting about 4k miles on the tires. There has been only one negative, but I'm not sure if it was the tire or a one-off. While stopping for a rest, at my vehicle, the bike in the full sun, on asphalt, about 80 degrees, the front tire spontaneously had a blow out. Latex (Stans) was everywhere. Probably just a one-off.

I bought these tires because Panaracer decided to quit making their Small Knobs in 43mm. The Continentals say 45mm, but they look to be the same width as the SK 43s. I've only had them on the bike for two months but so far so good. They were a little pricier than the Panaracers and I gave them 4 stars just because I haven't had them long enough to know how durable they are. Grip is good, slightly more aggressive than the SKs, but still low profile enough to roll well when on pavement.

32mm Gatorskin tires just barely clear on my Trek 1800c road bike, it was designed for 28mm OEM tires. At 265 pounds I need something stronger than the 25mm tires that were on the bike when I got it and they rode too rough. Every bump was harsh and I was concerned when I learned my 20/24 spoke rims were known to be prone to cracking. I measured my tire clearance and picked up an almost new pair of used 32mm Gatorskins to try out. They ride so much smoother and at a lower pressure than the old tires.

These tires might be 100 grams heavier than regular road tires, but at 50 pounds overweight I do not notice any difference in speed, they might actually be a little faster for me as they ride so much smoother. They also allow me to bike more often which helps my effort to lose weight. Without these tires I probably would have resold the bike and gone to a used touring bike or a new gravel bike for more tire clearance and better comfort. Now I don't have to do that.

So far no flats and no problems. With new tubes from BTD they do not leak much air either, I check the pressure before every ride and go. I top off the pressure about once a month.
