Was using Vittoria Rubino Pro.Bought the 2 at the same time so presumably from the same batch.
Long story short but on my 1st ride at correct psi the 1st tyre split on smooth road. Sh1te happens I thought to myself. Then a couple of hundred kms later the other split again on a very smooth road.
Dropped an email to the shop and they without any questions refunded me.Bad batch I thought to myself.
Then this eve I noticed on the Ultremo's I picked up that there was another split in the rubber. Again was under the max psi .I had the tyre at 135 psi.
WTF is going on?????

Pics? Why are you riding at such a high pressure? What is your setup? Rims, tube, rim tape, bike, weight etc....


Being vague doesn't help anybody answer your question..

Why am I riding at such a high pressure?
The reason I like the Vittoria's is the fact you cam pump them up and I love them that way. Plus when I left the front wheel in for a spoke to be replaced on the Khamsin in my lbs he whacked the Vittoria up to 140 and said that they are best that way. He rides the same roads as me.
Will upload the pics in a bit.

what do you weigh? running pressures that high unless you are super big does not make a lot of sense.

120psi is plenty for a 200lb'er....however, don't think that fully explains your tire busting.

Definitely more to it than tire pressure but you should reduce. As Btompkins indicated around 120psi is better. Ou want your tire to be able to comfort to irregularities of the road rather than deflect off them...

Just an update.
The Rubino's split was a complete failure ie the thread and the carcass had split and was revealing the tube.
On inspection during full daylight of the Ultremo's - the inner casing was fully intact and it was just the outer rubber had split. Have reduced the ultremo's now to 120.

You do realize that adding your own weight on top of those 135psi, actually increases the pressure even more. So you at 95kg at 135psi is not the same actual tire pressure as somebody 75kg riding 135psi. Think of it like filling a waterballoon nearly full and then squeezing it 'til it bursts...

You need to use wider tires, 25-28mm at your weight, so you can lower the pressure without getting snakebites. 23mm isn't for everyone.

Pressure is pressure. Doesn't change based on how much someone weighs. But I agree that he needs wider tires and lower pressures.

In the case where the tire is filled to the point where it really doesn't deflect under pressure, doesn't squeezing it increase the pressure per square inch. The tire will try do deflect but there is just nowhere for the air to go, thus the tire will burst.

Think of it like placing a football in a vice grip, and squeezing it.
