(Wheels and) tires are to bicycles what speakers are to hi-fi
Trying to improve performance by upgrading components can be something of an ethereal pursuit - sometimes it's hard to tell the difference; a lot of the time you can't help but "feel" a difference just because you expect it; and sometimes you can actually spend (a lot) of time and money and wind up backwards because multiple "upgrades" don't jive as a total configuration. But I am here to testify that - just as they say in hi-fi to spend your money on the best loudspeakers (and phono pickup) that you can afford, tires are where the rubber hits the road on bicycles. After riding for almost 4 months on the stock tires (Continental Contact 700x37) that came with my LHT complete bike, I finally managed to get a pair of Vittoria Randonneur Pro 700x32's. At first the ride differences were not so immediately pronounced as I had expected (considering the new tires look to be about half the size of the old ones), but the Vittorias straight up give a familiar ride about like I remember the 700x28 Randonneurs (60 tpi, non-Pro) that I used to ride on. But after leaning into a few turns, I am in 7th Heaven on these babies :-) These are my first ever non-wire bead tires. They mounted pretty easily. Because these are spendy tires and I don't want to wreck them, I stopped pumping at the sidewall recommended max 75 psi - even though I used to pump my 700x28 Randonneurs *well* past the recommended 80 psi (I think it was), and kept the 700x37 Contacts 5-10 psi above the recommended max 85. I'm sure the Contacts. BTW, are fine tires (costing almost as much as the Vittorias) - they rode decently enough as big hoses go, never slid out from under me, didn't flat too terribly much (never flatted the front), and don't show a lot of wear after at least a few thousand miles (the front looks practically unused). |

You might have found the stock Contis more charismatic if you underinflated them like you're doing with the Vittorias. Chalo |

Chalo I'm trying to remember something I read here before regarding comfort and efficiency on a bike. It was Fit, Fat, Fitness and ????? I'm sure there are lots of reasons to switch 28s for 32s or the other way around, change brands &c but if you want to make a big improvement on your cycling by changing something I doubt tires are the easiest way to do it. Me? I could drop 20 pounds. Cam |

Nonsense. With audio, the speakers are the only important part. With
bikes, tires are pretty much interchangeable. Any 23-25-28mm tire from any of the manufacturers will ride just about the same. You could not pick them out reliably in a blind test. Any 38-35-32 tire from any of the manufacturers will ride the same. Assuming similar inflation levels and tread pattern. 80-120 psi compared to 80-120 psi. Smoothish compared to smootish. Not smoothish compared to knobbies.

Bull****. Casing matters. I for one, can't stand the ride of the Contis with the gumwalls, like the Contact and the Countryride. I even tried a used pair of Speed Kings last week for the hell of it, and they rode like cheap nasty tires. Granted, they're cross tires, but still. Conti does make mtb tires with pretty nice supple casings, though. I replaced the Speed Kings with the spare IRC Tandems in the garage and the ride was much sweeter due to the finer casing. The Paselas on the other bike replace stock Kendas that weighed nearly a pound more each at the same width and also with gummy sidewalls instead of a quality casing. Night and day. I don't currently ride super skinnies, but the ride difference between 23mm Vredestein Fortezzas and cheaper low thread count skinnies is really palpable. |

The Conti's might have given you a decent ride if you didn't overinflate them. Let's consider your transducer comparison, would it improve your sound to stiffen up the phono stylus's suspension or drop another gram of tracking weight on it? That max pressure isn't even a recommended pressure maximum. I can't imagine why you'd want over 90 psi in a 37 unless you just really want to get on Mythbusters. "Is it true some moron blew the hell out of himself with a bike tire - we put it to the test." *The whole point of running a tire that fat is so you can lower the pressure. Assuming you use the recommended inflation pressure, casings differences can yield seriously different riding characteristics. The easiest example for me is a 28mm Bontrager Hardcase versus a 28mm anything else. Those Hardcase tires have endless belts and reinforcement and ride like a wheelchair tire. At lower pressures, they feel really sluggish. Now, they are super flat resistant, but comfortable and lively they are not. -- Jay Beattie. |

In the cartridge/stylus/tonearm/turntable days, this could be a HUGE difference. In the digital era ... not quite so much. Back to you.... |

Let's consider your transducer comparison, would it improve your sound to stiffen up the phono stylus's suspension or drop another gram of tracking weight on it? I'm pretty sure that neither of those changes would yield an improvement for my record player (quite the contrary), but it would certainly yield a change in performance, which is why I went out of my way to disclose the different inflation treatment I had given the (very) different tires under consideration. That max pressure isn't even a recommended pressure maximum. Okay then, the manufacturer's rated maximum pressure specification. I can't imagine why you'd want over 90 psi in a 37... Speed. ... unless you just really want to get on Mythbusters. "Is it true some moron blew the hell out of himself with a bike tire - we put it to the test." Gee, thanks :-) (The respect-o-meter just dropped precipitously.) *The whole point of running a tire that fat is so you can lower the pressure. The whole point of running a tire that fat in my case was that is what came on the bike; they worked okay; and I couldn't afford to replace them given the first two factors. Glad you're enjoying your bike. Let me suggest experimenting with pressure a bit. Ignore the some good, more better, too much just right thing you've been operating on and really test for what actually works better for you. Gee, why didn't *I* think of that? ;-) |
