Default New Tires

I have been using Conti GP 5000s regular tube required. I get huge mileage out of them say 5000-6000. I put a new set on today because they seem to be squared pretty good but I could still get a glimpse of the wear indicators.. They were wore down to the end but not totally disappeared. I think I could have gotten more miles but the back tire had a small sidewall type mark but nothing drastic or popping out.

Well I road the new ones and I sure could tell my cornering and handling was better. Did I imagine this or should I have gotten more miles out of the other tires. I guess my feeling it they are what meet the road don't be cheap with it?

I couldn't understand when you said that you were getting 5,000 miles on those tires before since I could barely make 2,500, Using Michelin Pro4 of Vittoria Corsa G+ I get much better wear. I will say that the GP5000's do corner a lot better and if you want very good wear and cornering the Continental 4 Seasons are very good but very expensive. The Pro4's corner very nearly as well as the GP5000.

But yes, new GP5000's do corner remarkably better than worn one's that have had the rubber age hardened. Though it used to be that you age hardened some tires to get them to corner well. (GP4000's?) As soon as the 5000's start getting flats it is time to replace them.

I do a lot of climbing on the tires and descending they get a combination of high speed on lousy California pavement so perhaps this is why I would wear them out so rapidly.

And like Joerg points out, do not use any tires with possible sidewall blowout problems. That can lead to a tire being thrown off of the rim. The reason that tubular tires were so popular in racing was because with the tire glued onto the rim you couldn't throw the tire off.

Used to get, about 2k on various road tires, with the gravel tires get fair
bit less, maybe 1.5k.

Probably as gravel is abrasive plus the tires tend to be softer.

If you blow a side wall on any tire, even a tubular that’s going to be game
over, a puncture no you can still keep on rolling, sidewall rip? Not so
sure I’d be confident you could.

My point wasn't that you could keep rolling but that you wouldn't lose control and go down. I've had both clincher and tubeless come off the rim. Really screws the rim up and luckily this never happened when I was using carbon rims.

Glued on or not a tire with a blown out side wall is probably asking to jam
in the fork, I agree the general reasoning which is that tubs can be run
flat, though as clinchers are apparently closed and overtaken in terms of
rolling. The argument not to use tubless + sealant is looking weaker.

I ran tubies for many years when that was the only good tires you could get and I never once saw a slashed sidewall. I had one of those plastic stacking boxes full of tubies and a couple of years ago I put an add in Craigslist free for the taking and a dozen people contacted me within hours. And these weren't even racing tires - they were training tires.

Life is too short to ride crappy tires. IMO the GP5000 are the best allround tire at the moment. Continental seems to be doing something right for more than a decade now. My gravel bike was delivered with WTB Riddler tires. They are good on gravel but I noticed that they suck on tarmac. My feeling was confirmed by RR measurements I found on the web. I put Continental Terra Speed tires on and that was a significant and very noticeable difference.. That Black Chili compound as Continental call it is some magical stuff.

IME not on their Gatorskin tires. They were expensive but three out of
the four that I tried failed prematurely with sidewall blowouts. Ok, I
milked 2500mi out of the lone survivor but at $45 that is still worse
than the 1200mi out of a $18 Vittoria Zaffiro and those never blew their
sidewalls on me. So Zaffiro are my go-to tires now for the road bike.
I've also tried CST but those were no good, less than 1000mi and the
rubber on the sidewalls began showing lots of little cracks.

To me reliability is key, with everything. Getting there without a flat
or blowout is much more important than cornering, rolling resistance or
other road-handling performance. My experience with a lot of bike parts
is that you do not always get what you pay for.

I haven't blown a sidewall on either the Gatorskin or the Zaffiro. I think the Gatorskin has better flat resistance than the Zaffiro and better wet traction, except that the Zaffiro has a tread pattern that offers better grip on grass/leaves, etc. Wet traction differences on smooth pavement are minimal. I don't know any tire that really outperforms on wet pavement. The Michelin Pro4 Endurance and the 4Season were good. I've got some Power Endurance, but I haven't ridden them in wet weather yet.

I'll admit to being a lousy judge of bike tire traction, especially in
the wet.

I wouldn't test traction while cornering. Ever since some bad
experiences as a teenager, I've been pretty careful at cornering. Except
on a mountain bike, I can't remember ever sliding out.

I suppose wet weather braking would be a test, but I do relatively
little riding in the rain, and then I brake about as cautiously as I corner.

I do remember one fun incident, climbing a steep grade (maybe 15%) with
a friend on the back of the tandem. He and I were working hard on the
climb and came to a place where a trickle of water ran across the road.
We spun the rear wheel a bit as we crossed the wet patch.
