Tan sidewalls deteriorate faster than all-black sidewalls?
Do tan-sidewalled tires deteriorate faster than all-black sidewall tires, in
your experience(s)? Or am I just seeing more deteriorated tires from when tan sidewalls were more popular? -- Phil, Squid-in-Training |

Phil, Squid-in-Training wrote: Do tan-sidewalled tires deteriorate faster than all-black sidewall tires, in your experience(s)? Or am I just seeing more deteriorated tires from when tan sidewalls were more popular? We had a thread covering this some while ago. I was complaining that IRC Road Winners and Tandems are now manufactured only in black wall. If the blackwall is carbon rubber, it will block UV light better, unlike the plain transparent rubber of a tan skinwall. So, if you leave your tires out in the Texas sun, as Chalo did, it seems the tanwall will deteriorate faster. However, for most of the rest of us, none of this matters. There are only old Conti self-destructing sidewalls (or chafing strips, as it apparently turned out to be), and everything else which lasts just fine. The rest of the tire will go kaput before you've finished with either tanwall or blackwall. In theory, since carbon is an energy-sucking material, blackwall tires should have greater rolling resistance. In practice, who cares, it's all mighty thin. It boils down to looks and the tan sidewalls win big there, the all-black being quite ugly, a perfect match to today's extraordinarily ugly fashionable bikes. Hard to imagine anything uglier but then they do manage to outdo themselves every year. Conti Ultra 4000s are available even in metallic colours now, man will you look good. No carbon but they do claim to add a UV filter, no reason a plain tan wall couldn't have that too. |

IME all coloured sidewalls deteriorate fairly quickly. Way back I had some
Michelin Bi-Sports with orange side walls on my training bike and the surface of the side walls split after a 1000 miles or so. I ride my racing bike on Vredstein TriComps with red side walls. These split after only a couple of months and soon look like crazy paving. I run them at 10 bar or 145psi and they will continue in service until the black centre tread part completely wears out. In total I have clocked up over 6000 miles on TriComps in this condition without a single flat and no noticeable deterioration in performance. My view therefore is that the rubber on the sidewall contributes very little to the performance or life of the tyre. "Phil, Squid-in-Training" wrote in message news:6dZ4f.5430$vk1.463@dukeread04...

Depends on the black sidewalls coating as well--some just have a little
skim coat of material coating the threads, others, like the 28mm cheapo Hutchinson Flashes I run in the city, have a thick coating of rubber over the sidewall threads for abrasion durability as well. As to the ugly/not debate: I find tan sidewalls to be visually messy, just like overly frilly lugs. They get grubby pretty quickly--I'll take solid black any day. Same goes for bikes--I like smooth top leather saddles w/o stitiching or "schvans-ports" like Turbos, and frames like Gunnar does 'em--nice smooth welds, traditional where it makes sense, and a little more modern where it doesn't. |

That's their max rating. If you believe rolling resistance is inversely
proportional to tyre pressure then that should be minimum rolling resistance. If you believe the risk of flats is lower at higher pressures then could that be the reason I have never had a flat with these tyres? The bike handles fine and the ride is comfortable. Centuries are no problem. So I have never bothered to experiment with lower pressures. If you can offer me any positive benefits from running them lower I am willing to give it a try.

I don't think tan or coloured sidewalls last much better than black, it's just that black hides the aging better. It's the casing, not the coating that matters in road tire sidewalls. -- waxbytes |

If you park your bike out in the Sun at work all day, as I do five days a
week, then the sidewalls of tyres without rubber on the sidewalls do perish more quickly. On my other bikes that live in the garage when they're not being ridden, the sidewall outlasts the tread.
