Tyres - How Long Do They Last?(14 posts)

Tyres - How Long Do They Last?Bananaman
Sep 26, 2003 1:22 AM
I have a set of Michelin Axial Pro's on Ksyrium SSC's which have done 4000km and are still going strong without noticeable wear. These are a good durable set of tyres but unfortunately they dont make them anymore since they were replaced by the Prorace which are inferior. Anyone got over 5000km on a set of these tyres?
How's that?filtersweep

ProRace inferior?

Frankly, I found it the other way around.

Life is too short to bleed every inch out of a tire. You will likely soon blow a rear sidewall for no apparent reason. The wear might not be "noticeable"- but I'd guess if you took it off, it would be paper thin in spots and weigh substantially less than when you put it on new.

The Ksyrium/Michelin is a nice combo- nothing inside the wheel to puncture the tube!

There's no way that a rear tire won't have substantial wear after that many miles. I can get up to 5000km out of a rear Conti GP3000 and 2-3 times that from one on the front. By 5000km the rear tire has a very flat profile and it's paper thin.

I'm at about 4000 on my pros and the rear is getting very flat looking. Tread is good but they are losing their rigidity. Still a great tire.

Perhaps I was being too generous....I should have said that there werent any signs of thread coming through the rubber as everything looks OK. I had a set of Prorace but I found the rubber compound too soft and vulnerable to cuts. I've bought my next set already,specialised 'S' works in red and black. Cool!

the softness is what give the tire its nice ride- I think the Pro Races ride like garden hoses compared to a "real" tire like a Veloflex- and the Specialized will definitely seem like a garden hose compared to the Pro Races. It is the catch-22 of tires- you either have a nice ride/handling or durability- but not both.

Wow, very impressive, I never got anymore than 500km out of my two ProRace tires. Both tires blew out on the sidewall and had to be trashed. Needless to say, Michelins won't be hitting my rimms for a while now.

I can only hope to see that kind of mileage on a tire.

Asking for mileage or years is subject to way too many variables.

For ex:

1) Tread compound and how fast it wears.
2) Sidewall and casing construction and how susceptible it is to cuts and penetration.
3) Rider weight
4) Riding style - some serious power to the pedals will wear the tire out much faster than a gentle roll.

I ride about 3-5,000 miles a year. The treadwear is important to the extent that if you wear the tread down too far, the tire is more vulnerable at the point of contact.

But I usually have to replace a tire due to cut sidewalls or other casing damage rather than due to treadwear.

A good example is Conti GP3000 vs Michelin ProRace. They are both good tires. Maybe the Conti rides a little nicer when new. But the Michelin sidewalls seem a bit more robust. Just my opinion from experience.
Oh, and I get about 2 to 4,000 MILES on a rear tire...Fez

Fronts usually have hardly any wear, but can still have minor cuts and scrapes. Anytime there's anything deeper than superficial, it gets replaced, period.

After 4,000 miles the rear still looked fine, but I replaced it just to be safe. My current Conti GP3000 rear will be lucky to see 2,500 miles

I never wear them all the way down. Like someone said, life is too short to worry about stuff like that.
Nothing like that for me :-(Zman

I get about 700 miles out of a rear GP3 and 1500 miles on a front GP3

burn the pavement under you and could probably smoke me.

Maybe my good luck with tires is because I go so slow and put out such little power.

Same poor results for me with the GP3000bimini

I quit using them the GP 3000 for that reason. Switched to Vredstein Tri-Comps. So far so good at 1500 miles (very slight flat spot on the rear). Also the 23 cm is higher pressure and smaller diameter the the GP 23 cm. Ride feels less harsh (unless I pump them all the way up to 145)

Next pair will be another pair of Vreds.

So I'm pretty sure I'll be buying them again. The back is squaring off but still good life left. Front is hardly worn at all.

That's a good record without a flat so far. You must be using latex tubes like me. So far only one flat due to a nail which would have gone through any tyre. Latex tubes lose air very quickly but they certainly help reduce frequency of flats and I would say they give a smoother ride. I'd even say they help prolong the life of the tyre but I think someones gonna shoot me down with that remark!
