I've got 2500 miles (4000km) on a rear GP4000 and it's just started to square off. If I rotated them I could probably get 8000km out of them.

This Continental Ultra ll run tubeless at *2700 miles rear .. 180's weight for me ..riding flat bar.
Lots of rubber left.. Conti uses same compound for all the road tires I believe reading their site.

For sure.. the Orange Endurance is doing it's job. :thumbup:

One guy Tx had 3800+ on a set w similar wear indications.. same weight.

*Corrected from 3000.. which is likely correct. Went thru logs and data readings... figure re-posted to show minimum mileage..
at least. Like my stats correct........

Stan's Race is just Stan's with less water and larger particles.
It doesn’t smell the same, and can be removed by hand when dry. There must be something more than just that, but ok I’ll try Orange!

Nope, more like 85kg.

Brand new 25's. Got a wicked cut on the rear. Pissed out some stans, slammed a Co2 and it sealed right up.

Good job :thumbup:

One note if you havent already, I'd replace that Co2 with air when you can - I find that Co2 seems to make my sealant go off quicker.

That would mostly be from coagulation caused by lowered temps. CO2 also diffuses through membranes like tire casings faster than air, but I'm not sure how that would cause sealant to dry out faster. You should mostly be fine if you use CO2 with the valve in the 12 o'clock position...whereas normally you would want to pump up your tubeless tires with the valve at 8 or 4 o'clock.

Might be a stupid question but why at 8 or 4?

Mavic Ksyrium Pro Carbon UST 2019 and impossible to fit (I am able to fit ANY other tyre and I know all the tricks) Gave up too and returned the tyres. Maybe the 25 mm version is too narrow for the wide inner channel of my rims (21 mm internal 27 external). 28 mm or 32 mm version will be better? Worth a try? (I hate Mavic Yksion UST since too fragile)
Thanks

So any sealant dripping down the sides of the rim doesn’t end up in the valve and any sealant in the valve can drip out.

People have observed that the tire beads will stretch over time, meaning they were hard to put on when new but easy to take off when worn. If you have a non-TL rim you could try mounting the tire on the non-TL rim and inflate it with a tube. Let it stretch for a week or two. Worth a try.

thanks nice hint indeed but have already tried as last resort (have to admit have unmounted after only 8 hours :) because both I was too curious to see if worked and also had to return tyres fast as possible to the shop) But I believe that trick works with normal clincher tyres only since tubeless ones are "famous" for having strong beads that is the most important part of the tyre to assure not blow off the rim :(

Any tubeless tire that has beads that permanently stretch is a poor tubeless tire. Beads shouldn't do that for both safety and ability to air them up easily.

That’s why I don’t use tubeless tires
