If so, probably a CYA after the SUV rollover mess they had. precisely what i was getting at. a vehicle should NOT roll because of a flat. period. ford knew it did. but they did the math on the costs of redesign and chose to ignore it as a cheaper option. and they bribed their way out of trouble when it eventually came. there should be jail and giga-fines for the "executives" that made those decisions. /way/ worse than enron. http://www.safetyresearch.net/Library/SRS046.pdf |

And I only had one bike then, and I kept it inside when I was at home. Folks who only ride on pleasant Sunday mornings when the temperature is between 60 and 85 degrees may fail to appreciate the prevailing conditions of a place where it can exceed 100 degrees every single day for almost three months running. Sheldon Brown used to point out that bike tires were still good for decades if not worn out or damaged, and I agree. I have NOS Goodyear tires for 20" bikes that are still soft and grippy after around 40 years in the wrapper. I'd be a fool to ditch them just because car tire makers want to sell more car tires more often. Chalo |

You're probably right. I hear you're the expert on all things bicycle. (Next to T. Sherman.) Been reading Ed Dolan? You don't need to read Ed Dolan the Great. Just read any of Mr. Sherman's explanations of various recumbent advantages. However, just because he is knowledgeable about recumbents does not mean he is equally knowledgeable about all things under the sun. Quite the contrary!

Dear Erness Wild:
On Apr 26, 8:03*am, Erness Wild wrote: .... Here's a photo of how bad this tire is: http://i44.tinypic.com/30clma9.jpg and I'm not complaining, really, just a bit puzzled over what makes a good tire (many of which don't seem to last anymore) and this old tire that keeps going even when falling apart. Understand that "accountants" force manufacturing to make choices based on economics. Having the tires fail "six months" after you buy the rest of the machine, does not denigrate the rest of the machine, and will not lose customers. I'm surprised car manufacturers don't ship their cars with four tiny spares like they put in the trunk now... My two cents. David A. Smith |

"circus clown equipment" would seem more appropriate for you. snip I live a couple days' ride north of Chalo and I have to back him up on this one. Between the UV and the Ozone tires don't last very long here. I have had to throw away tires that had less than 500 miles on them because the carcass had split from weathering and pollution, in all areas of the tire, tread, sidewall and near the bead. I have had tires go bad that I though were whitewalls until I demounted them and discovered a black bead that faded to chalky white. TX is running neck and neck with SoCal as the most polluted area in the US. SoCal levels are a tiny bit higher, but TX are over a much wider area. Opus |
