DETROIT, Nov. 8 (UPI) -- A Massachusetts consumer safety group wants Washington to require easy-to-read "born-on" dates for vehicle tires, the Detroit News said Monday. Safety Research & Strategies cited 50 crashes resulting in 37 fatalities caused by older tires with very little wear and tear in its petition to the National Highway Traffic Safety Administration.

I just bought an older bicycle (1980s?) a few weeks ago, and its tires (27"😉 seem to be old, but in decent condition. Should I replace them anyway? -- Ben Pfaff email: [email hidden] web: http://benpfaff.org

Yes! over time the rubber loses it's oils and elasticity so there is no grip when you need to turn quick or stop on wet pavement. i had to learn this the hard way. -alan

Are there any cracks in the rubber or mold/mildew on the casing?
No mold or mildew. I don't know what qualifies as a "crack"; there are numerous short, narrow, very shallow striations parallel to the rim, but nothing deep enough that I'd call it an actual crack. -- "Now I have to go wash my mind out with soap." --Derick Siddoway

Interesting. I thought the braking was poor because it's a cheap older road bike; I certainly do get better braking on my 2003 Trek 2300. It hadn't occurred to me that tire performance could be an issue too. -- Ben Pfaff email: [email hidden] web: http://benpfaff.org

Chrome or alloy rims? Brake shoe condition/age?
I assume that a magnet would stick to chrome rims, but not alloy? Then they're alloy. The brake shoes are in good condition.
I guess the style of brake could be another factor? The Trek 2300 has Ultegra dual-pivot calipers and the old bike has "Weinmann 610 Vainqueur 999" brakes which according to a website found via Google are centerpull calipers. Actually according to the same website those brakes were made through the mid-70s, so maybe this bike is older than I thought.
This bike is also certainly heavier than the Trek: steel frame and outfitted with a rack and baskets. It's for commuting and grocery shopping mainly, whereas the Trek is just for fun. -- "How could this be a problem in a country where we have Intel and Microsoft?" --Al Gore on Y2K

Odd, my car has been on the same tires for 10 years. I asked our mechanic about them because they've got a lot of little surface cracks, and he said not to worry. (My mountain bike has been on the same knobbies for 10 years as well.)

What's odd? The fact that you drive on the same tires for 10 years or the fact that older tires, with very little wear and tear seem to present a greater risk of crashes? Obviously, you know that just because you're riding old tires don't mean the observations are wrong.

The oddity is that my mechanic and the "safety group" seem (SEEM) to be in disagreement, although the story clip doesn't actually specify the tire ages.

The full article, if I recall correctly, said that tires older than six years were considered to be "too old" in the study. -- Ben Pfaff email: [email hidden] web: http://benpfaff.org

Is your car kept in a garage? I would expect outdoor parking to cause more rapid ageing.

80% outdoors during their lifetime. I was a bit concerned about the age and surface cracking, but the mechanic said they were fine. They could easily go another couple years before the tread gets too low, but I may reconsider now.
However, I'll take my chances with my mountain bike knobbies.

The same tires for 10 years? I wish I could get 6 months out of my tires. I think it has something to do with the way I drive and especially the way I park. :-) The curbs jump up and hit my tires. I can't even imagine having tires 10 years unless I kept the car in the garage. http://hometown.aol.com/lbuset/

*Car* tires every 6 months? Dayum.
Rotate, and take some of the lead out of that foot.

I think it has to do more with the way I park. I can't seem to park a car without hitting the curb. I've been trying to master this for over 30 years. I am losing hope. :-( http://hometown.aol.com/lbuset/
