Appreciate you sharing your experience with us Mr Purple. Your sacrifice has helped others avoid the same experience.

Agreed. :)
They sound sh ite and are now classified as such.
Mr Purple had a bad run with them, but I've racked up almost same Kms with absolutely zero issues and barely any wear. Roll beautifully to me, and rate them better than the GP4000s they replaced.
They don't roll that well according to this comparison.

I'll stick with the GP5KTL

Yeah, I've seen that, though one can argue that such testing fails to translate into real world. My butt tells me that the Goodyears are at least as good as the GP4000s, but who am I to argue...

I'll take a measured comparison over user anecdote personally.
Not having a go and appreciate the feedback however. :)
A measured resistance is a valid comparison tool when tyres are measured the same way at the same pressure and the resistance is compiled.
Yeah I've heard a rolling drum is different to a road, Jan Heine likes to make that claim when marketing his Rene Herse tyres, but it is a valid enough tool to illustrate differences imo.
The Contis are a great tyre ime. Given there are options that measure closer to them in terms of measured rolling and puncture resistance the Goodyears are down the list.
Glad you are have had a good run from them though.

Does anyone use Maxxis High Roads clinchers?My local 99bikes have then at a reasonable $62.

2019 review:

https://www.bicyclerollingresistance.co ... -high-road
The Maxxis High Road is a fast-rolling tire but comes a bit short to challenge the top performing tires in the all-round category. It does offer a slightly better puncture resistance of the tread area when compared to the direct competition. Another positive is a very low weight for the puncture resistance and air volume it offers.


We rate the High Road 4 out of 5 mostly because rolling resistance is the dominant ranking factor on our site. We feel the High Road is an excellent choice if you're looking for an all-round tire and you don't need those last few watts to be competitive. If wet grip and durability turn out to be better than competing tires, the High Road can be an excellent tire.

Well after following this thread I bit the bullet and decided to try some 5000s. They just arrived today so will see how they go.

I put some on my new Kotavelo R21s today... bit of faffing around.

Tried the 28mm High Road on the rear first, but it measured > 30mm and wouldnt come close to fitting. So put on my 25mm gp5000... but theyre not as wide as the 4000s :(, which measure a good-ly 27mm on my bikes. The 5000s are exactly 25mm.

Still , wheels roll and handle nice. Not perfectly straight, but tight. Just have to get that asymetric bulge out of the rear tyre somehow.

So apparently I am a murderer of rear tyres. I'm tracking the mileage now, and these are 2300km old GP5000s.

Well that would explain the lack of grip. I'm not sure what the answer is, but suspect it's because I'm a violent climber and do a lot of it.

Gee, that's not much mileage for such wear.
I've come to the end of a stash of GP4000's. They've been lasting for about 7K in 23 and 25mm and remarkably, nearly double that on 28mm. I do ride with much less power than you.
About to replace a 25mm Schwalbe One rear tyre at 6000. I'll stick with them on that bike to match the red tyre stripes.
Someone recommended Conti Grand Prix as a good durable and reasonably performing tyre. Neither GP4000 nor GP5000, just generic GP.
Thinking I might try them next.

It was actually worse on the other side, big chunks out it everywhere.

The problem is lots of climbing is followed by lots of descending, and I'm not sure I'd want to run a harder tyre. I suppose one every three months is still only $280 per year.

I switched to the Grand Prix on the rear of both bikes in 25c and 28c. This was after the GP5k 25c rear was killed by a sidewall cut after just 700km. The 28c GP5k only lasted around 3500km and had numerous cuts. I've been happy with the Grand Prix on the rear. It has the Black Chilli compound of the GP5k but extra puncture protection. 25c has done 4500km and 28c over 4000km without issue,

I got to using the P-Zero Velo in 23mm size, they seem nice - I used them in dodgy weather conditions. They are on the Canyon Ultimate.

I just put a set of Velo in 28c on my disc brake bike with first ride tomorrow, so it will be interesting to see how they perform.

I am 76kg.
Do a bit of climbing but not as much as you.
4200k out of my rear GP5000TL.
Wear indicators gone but nothing like that :o
No punctures still and another on the rear.
7100 k on the front TL. Still fine.

I have P-Velo 4S in 28c and they've been really good. So easy to fit without levers as well.

Wider tyres which should last longer, but yep you are hard on tyres Mr Purple.
Must be smashing it up those climbs 8)

https://www.bicyclerollingresistance.co ... rance-test


There was some tyres sent in by users at the end of that link.
One bloke had 7 flats and wore out in 1800km.
I'd never use them again after that!
He reckoned his previous set lasted 8500k.

I'm thinking it's the 35km/hr+/6%+ big ring KOMs. Probably not the smartest thing to be doing it you're worrying about tyre life.

Might go back to the Pirelli P Zeros, I was using them before and they wore out but at least never delaminated.

Tubeless intrigues me but I might get it right on a gravel bike first.

The 5kTL are without a doubt the best tyre I have ever used.
Love em.

Unfortunately they have been replaced by the S TR.
I will use them after my TLs are done, but I don't see them being better. Thinner and lighter.
I am no weight weenie. Couldn't give a rats about a few gm of tyre weight. The TR don't roll any better and they are thinner so I don't see them lasting better.
We'll see.

90PSI, though I've since dropped back to 80PSI.

Most calculators say that's about right, and in Brisbane there are a lot of potholes for the inevitable pinch flats.

Half thinking I should go tubeless but simultaneously worried I'll just end up having to change those every 2000km too, and they'll be more of a pain.

6500 km on my GP5K TL's until I got a big hunk of glass in the front.
Rear was squared of so it was time to change anyway.

Changed brands only due to availability. Vittoria's went on easily, I do have compressor for inflation though.
I am a tubeless convert, two sets for 11500 km and the only time I had to stop for a puncture was the glassing.
Could have fixed on the road, but only 600m from home

Yeah I'm a convert also.
11300 on the roadie and haven't had to stop for a puncture.
Everything has sealed.
Even pulled 2 pieces of tyre wire out of the rear tyre.
Sealed no probs.
2 punctures with tubes.

Only 1600 on the gravelly, but I have had to throw a tube in there.
Pinch flatted the front tyre on an unseen rock.
Hole was up near the bead.
Has a patch on the inside now.

I still have plenty of tubes in stock from my tube days. They will all die of old age still in their boxes now :)
