Trashing tyres?
Postby toolonglegs » Fri Aug 22, 2008 5:29 am
Anyway was a awesum ride as the other pics show!...apart from the 14 k descent that had a speed limit of 50kmph which was still probably too much on this tyre!...usually will hit 80-90 in parts .
C'est la vie!.
This was nice...
...this was starting to hurt!.
Lifes tough!.

I've had a similar problem with 26" Conti Sport Contacts on my old commuter bike, but just one time. The more common problem I seem to have is destroying sidewalls on my commuter, but that's more to do with my riding style (or lack thereof )

BTW Ultra Sport is a cheapie, so I'm assuming its just a training tyre.

Riding through France is just a wonderful thing, isn't it? I'm jealous as hell - not least because it's about 3º here today.

It's not surprising when you consider the air pressure involved and the surface area inside a tyre - the forces involved are HUGE. High quality tyres with high thread-per-inch counts are always going to resist internal damage better than a cheap low-TPI tyre. AFAIK, they distort this way when the reinforcing fibres (kevlar/nylon/cotton/whatever) stretch/break. IMO, once it's started to go you should toss the tyre as a blow-out at speed has become a real possibility.

On the tyre issue I feel your pain,none of mine lasted more then 2500km....there is just no answer, as I tried Vittoria,Michelin,Hutchisons......and none of hem lasted more then 2500km,but something similar happend to my Vittoria tire,it just exploded after 1000km......
BTW,you will get your arse kicked at handball today....

I concur here. Try the GP4000S, an excellent tyre. Even though the RRP is almost double that of the Ultra Sport you will probably get at least double the k's.Parrott wrote:Have never used an ultrasport. Have used attack/force combo, gp3000 and gp4000 with no problems. Good wear rates, good grip, compliant feel and only one puncture, difficult to get on the rim though.
Not trying to be rude here, but with a heavier rider the quality of the tyre used becomes more important especially when riding large k's and putting the tyres under duress on long climbs

...and yes it is tough riding here ...I was thinking while climbing yesterday if I built up a lightweight mtb with Ultegra cluster and derailleur I could get up here even in the snow

But the Bontrager only lasted a year. It replaced a Conti that had lasted several years. I've worn out two sets of Conti touring tyres and some other one-off brands, and NOTHING compares with the lifespan of the Contis. I feel like they make me work a bit harder, but the durability is worth it.

I just got a new tyre, i also stopped telling people how my tyre got a "S" shape kink in it, because i don't think many believed me:).

I am not sure about the mtb'ing...yes alot of private property signs everywhere but it is a pretty big sport here so can't be too bad...haven't replaced the mtb frame I snapped 2 weeks before leaving syd yet...winter riding gear is taking the money at the mo.
Yeah when I take my camera along it usually means I am cruising..not yesterday thou...on the climbing section my hr averaged about 175-80 and I only stopped for 5 sec piccies so it didn't drop below 145.
It is raining now but I am tempted to do a hard climbing ride tommorow... might even drive somewhere first.My favourite past time here is looking at maps...my local climb which I did yesterday is the Chartreuse de Portes ( http://challenge-big.eu/list/263.htm )...it has 4 ways here marked to climb it but there are about 8 totally seperate variations ...AND IT IS JUST THE FOOT HILLS TO THE ALPES !!!
