Buy that new tire with pride :-) It's also not odd for r.b.* posters to tire of threads even more quickly than that ;-) |

I think even the best tires are only good for maybe 2,000 miles on the rear and 3,000 on the front. I wore out my MTB knobbies at about 4,000 on the rear, while the front is still in use as a spare in my bike shed. I haven't got enough miles on my road bikes 27" and 700cm to comment yet. Bill |

I submit that on or about Sat, 01 Oct 2005 08:23:57 -0700, the person
known to the court as Bill made a statement in Your Honour's bundle) to the following effect: It would have probably gone with a resounding 'Boom' at 100 PSI or so. More of a crack than a boom. DAMHIIJKOK? I think even the best tires are only good for maybe 2,000 miles on the rear and 3,000 on the front. I wore out my MTB knobbies at about 4,000 on the rear, while the front is still in use as a spare in my bike shed. I haven't got enough miles on my road bikes 27" and 700cm to comment yet. Maybe. I have got 5,000 miles out of a Michelin Club Tourist back in the day, but 1,500 is good going for a Stelvio on the 'bent. Overall I find that real touring tyres like the Conti Top Touring and Schwalbe Marathon last much longer than no-name tyres or performance tyres like the Vredestein s'Lick. The most disappointing tyre I used was a Panaracer Pasela slick - wore out in no time and punctured if you so much as hinted that there might be a stone in the next county somewhere. But the Panaracer Pasela TourGuards we had on the triplet (as in three seats) were barely worn after something over 2,000 miles. If you are really concerned about tyre life, ask a tandem rider for a recommendation. My tandeming friends are mainly on Conti Top Touring at present, I think, but some are experimenting with Marathons. Guy -- May contain traces of irony.

I don't ride my 700cc roadie that often, so its tires are still pristine...
However, I ride my 27x1.25 Hybrid at least 60mi per week, so I can comment... Both tubes are "slimed" and the rear has at least four (sealed) punctures that I can find... The tires were puchased in Dec. last year (merry Xmas, me) and although the rear tread hasn't worn thru yet, it's very definitely wearing thin. Will probably swap the front tube AND tire for the rear tube AND tire. (downside of slimed tubes -- the tubes get STUCK to the tires.) |

Tires are tires, and would wear similarly hybrid or road bike, afaik. Unless you're riding on other than asphault, such as sand or packed dirt or crushed granite. I'd think the abrasive shear (just picking a term) would be the greatest on the hardest surface. On packed dirt I'd think a tire would last a very long time, more than a year's worth of 100mile weeks. On concrete/asphault, apparently it's about 8 months. Might be greater for heavier riders; pressure, friction has to be higher for heavier riders. Both tubes are "slimed" and the rear has at least four (sealed) punctures that I can find... Uh, not related, istm - I'm talking about grinding down the rubber of the wheel down the centerline over time. The tires were puchased in Dec. last year (merry Xmas, me) and although the rear tread hasn't worn thru yet, it's very definitely wearing thin. Ok, that's interesting - how do you know it's wearing thin if you can't see tread. Just curious. I think one way to tell is the width and depth of the 'flattened' center strip. Newer medium narrow tires (25c for example) almost have a slight 'peak'. When that wears down it become a 1/4" wide flattened part. When it reaches about 1/2", then the thread starts to show, ime. Will probably swap the front tube AND tire for the rear tube AND tire. (downside of slimed tubes -- the tubes get STUCK to the tires.) Yeah, I think I'd spring for new tires rather than muck around with that stuff. Never had a flat since I bought the original tires. Even with frequent flats, I think I'd avoid slime. How much does your bike weigh? Wouldn't be surprised if the slime added a pound. Thanks to all commenters. jj |

A better idea, is to put a new tire and tube on the front, and put the old front tire and tube on the rear. While front tires last much longer, rotating the tires, means you now have a crappy old tire on the front, and a front tire blow out, usually results in a loss of control, and that is not something you really want.

Walking a mile or two I can handle, but a blowout 20 miles from home would really ruin my day. Even slime can't help a worn out tire if you have ridden it through the cord. Bill |

I was on a ride and heard something flapping... like something was stuck to my tire. I thought it was one of those maple seedlings or some other junk.. when I stopped I saw it was a piece of tire peeling away. Looked sort of like a sharks tooth, and the tube was exposed and bulbing out. I thought "that's not cool!" And decided to head home, hoping that nothing would happen. The next day I got a new tire. |

That's true, actually a good idea, is to replace a tire BEFORE you get to the cords. When you get a tire to the point where it should be retired (yeah the pun is intended), take it off the back, put the front tire on the back, put the new tire on the front, throw the old one in the garage or basement, as a spare. If you already have a spare, take it to the bike shop or a automotive shop, and see if they recycle tires. W |
