Between GP5ks and Corsas, for fewer punctures I'd go with the former. I have both, and I LOVE the Corsas - at the same pressures, they're so much smoother riding that I sometimes look down to see if they're flat. The problem is, occasionally they are, a little bit more often than the Contis on the same roads.

I should note that where I ride sidewall cuts are generally not an issue, but glass bits are. And rocks that cause pinch flats, because I am a pothole and rock magnet. If there's a bump, a pothole, or a rock, I'll find it.

25's are for wimps. Real men ride 23's pumped up to 140 psi.

If a tire ruptures, it isn't the fault of the inner tube. By itself the tube cannot contain high pressure, rather it is the job of the tire to contain the inner tube. A gunshot type failure is a result of either a failure of the tire casing or of the tire bead blowing off the rim.

genejockey 

Yeah, two of the 3 incidents described are tire failures, not tube failures.

Though it's unclear what Michelin has done with the Power series of bike tires. Going by Michelin's bike website, a lot of the previous "Power" series tires aren't shown anymore (Power Endurance, Power Protection, Power All Season, etc)

And they’re sew-ups that you glued on yourself.

Only little baby-men run clinchers.

I always wondered if part of leg-shaving was because the glue for tubulars gets in your leg hair and is a mess to get out.

I just retired a Corsa with under 300 miles because of a cut that won't seal completely and started bulging. Upon inspection I found multiple other cuts, although they were holding their shape and air. Too bad, because I really liked the ride quality on them. I don't think I have ever used Conti 5000's but I don't see why they would be much different considering they have the same purpose in mind. I don't ride on gnarly roads, but they're not perfect either. For that reason, I just bought a set of American Classic "armor" Timekeepers to try, and if I don't like them will go back to the trusty Gatorskins because too many flats really take the joy out of riding.

I rarely get flats. The GP5K ride slightly faster. The Corsa G+ are slightly more comfortable, and easier to install.

I thought real men ride 23 mm tires mounted on 622 x 21C wheels at only 110 PSI so that they cannot be accused of having light bulb shaped tires.

Haha touche...

I blame my word choice I guess, but really since long before I made this thread - whole years in fact - I've just wanted a zero drag roll.. and in my head feeling the road ... Grundle on under my tyres is part of a sensation of .. surface ignorant speed... I give up lol

20's

the wimpy guys over 70 rode the 23's ...

Greatestalltime

What are some opinions on Pirelli P Zero? TlR or clincher? Some YouTube guys say they like them better then GP5000 for great all around tires.

tajimirich

I would have got them in a heartbeat but they cost double what gp5000s and vittorias do where I live... The specialized ones that are apparently also really good simply aren't here (Japan)

I'm currently running the TLRs in 28mm - I've posted about them in the Favorite Tubeless Tires thread.

They're certainly in the conversation for the best all-arounders that I've tried and I'd say that it's splitting hairs when it comes to ride characteristics (I don't think they're as supple as the Pro One Evo Addix, but I think they're the most grippy that I've tried in the last few years, tests show that they give up a couple/few watts to some of the others). They installed easily and seated with just a floor pump. I've got about 2k miles on them - the rear is starting to square, but I don't think that it'll have a problem getting to 3k, which is good for a high performance tire for me.

I haven't tried the Conti - the previous TL isn't compatible with my rims and I haven't gotten around to the S TR, yet.

Greatestalltime

Thanks! Good to know they’re easy to mount. The GP5000 do not go on Bora’s easily at all. I think I’ll give them a try next time after years on Conti.

I found them here for less than the 5000s. Even with shipping to the USA.

WhyFi

FYI, most, if not all, of the new performance tires that are coming out are ETRTO compliant, so mounting experience should be similar - I've been able to mount them all with just a floor pump. The GP5k TL are not compliant, which is why (I think) the S TR refresh came through relatively quickly.

PeteHski

Yeah, the latest GP5000S TR mount very easily. At least on my DT Swiss rims anyway. I believe the previous generation (which I never had) was widely criticised for being difficult to mount.

PeteHski

I liked them (Race TLR 30 mm version), except for me they punctured too easily and I had to retire both very early in their life (under 500 km I think from memory). I could have just been incredibly unlucky, but I haven't had such issues with other similar tyres. I'm currently using GP5000S TR and they are unscathed after 1400 km on rough roads. Nice feel and solid grip too.

Greatestalltime

Yeah. Might just stay with GP 5000. I just switched out a pair and no flats 3-5 k miles. And I had an easier time mounting the new ones.

At 25 mph, the difference is closer to 100 watts (combined RR of two wheels). Unless you cruise around slowly all the time, they make a big difference. About as big as aerodynamics.

I love the gp5000 in 23/25/28mm ( what ever is on sale ) if I am trying/wanting to go fast. I can't ride them daily, too many flats tubes or tubeless. I prefer gravel king slicks 32mm for daily solo rides.

t2p

Is the GK slick more puncture resistant than the GP 5000 ?

and is 23/25/28 mm to 32mm a good direct comparison ? (for your use - answer might be yes almost entirely due to increased size of the GK slick ?)

Have no experience with GP 5000 (but do currently have a pair on the way) - but was not overly impressed with the tread thickness and reports/reviews on the GK slick (and purchased GK SS instead)

Ramshackle

I replaced both Vittoria Corsa G+ 2.0 tires because they both had sidewall punctures. Both tires also had lots of tread left. Comfortable tires but weak sidewalls. Never had that problem with Conti 4000s.
