How critical is road bike tire pressure max?

That's a bit low for my taste. The Zafiro I have on there now says 100psi min and 130psi max which is more up my alley. By how much can a low max rating be exceeded? I like 100-115psi on my road bike in back. On the front I won't exceed the max because a blow-out would be nasty and that carries less weight anyhow. -- Regards, Joerg http://www.analogconsultants.com/ Is this some new California fad, riding offroad on narrow rubber? Whatever for? BTW, I have no problem with low- or zero-tread tyres because I ride mainly on tarmac, even in the narrowest lanes, but surely a mudplugger wants considerable mechanical grip. No fad but road bikes out here must cope with road sections that are either gravel or dirt. Part of life. There's a good reason not to blow up tyres over the max recommendation: It can get pretty nasty and expensive when overinflated tyres blow the rim apart. It is well worth reading Andy Blance, the designer of Sheldon's beloved Thorn bike, on tyre inflation: see page 36 at http://www.sjscycles.com/thornpdf/th...a_brochure.pdf It's a 30+ MB file and their server seems to be on an old dial-up line. I was a convert to comfortable suspension and inflation regimes already in my motor-racing days, and achieved the same results the same way in cycling: see http://thorncyclesforum.co.uk/index....16360#msg16360 (which is an extended version of a reply I first made on RBT to a query by Pete Cresswell) and read on in the ensuing very well-informed engineering discussion about ways of determining the optimum tyre inflation. In fact, there are all kinds of really good reasons for inflating bicycle tyres to the lowest you can get away with short of snake bites. Right, and then you get a pinch flat or snake bite which is often unfixable in the field. All it takes is one pothole. No thanks. Do you not carry a tube? You can squeeze one in next to the heart-lung machine, rope, winch and iron rail segment used for pounding in chain-pins with found fence nails. There should be room in your pannier somewhere. Yeah, I thought snake bite meant something else out there. Like through the rim or something. I guess a spare tube is a cop out or something. Myself, I carry two and I've hit a pothole before where I needed two. |
