Tire size for 180 lb rider

Now before everyone starts laughing, which is pretty understandable, once must understand that this company is the largest bike tire maker in the world--so their quality spans the spectrum! Anybody who laughs at the statement that Cheng Shin (isn't there a 'g' in there?) tires last forever has never used them. Every one I've ridden refuses to show any wear whatsoever no matter how much riding nor how much abusing is done. The only reason to change them is if you want tires that ride/feel different. They're slightly tougher than cast iron, and slightly lighter. I've never gotten a flat through one, nor worn one visibly. Regulars may recall me pestering people for imformation about tyres a couple of months back. It's taken longer than I planned but I finally got rid of my Cheng Shins! The problem was I also needed other bits and pieces as well so every pay I'd look at my tyres and think, well, it's not like they're actually worn or anything so they can wait. The problem with Cheng Shins is that by that philosophy I'd still be putting off replacing them about three years from now. After much questioning and listening and reading and pondering I bought some Avocet Fasgrips Duro-Plus K 700x32s from the States. They arrived Wednesday and I put them on yesterday. (As an aside, I was very proud of myself given I haven't replaced a bike tyre for at least 25 years. At least now I know I could do it on the road if I had to). Talk about chalk and cheese. I only went for a short test ride because of the foul weather but I swore the bike felt lighter and more lively. Then I wondered if I wasn't just mentally justifying the expense, so I put one of the Cheng Shins on the scales. Bike tyres aren't the easiest things to weigh if you don't have hanging scales but by my estimate my old 700x40s that came with the bike weigh around 680-690 grams each! The Avocets nominally weigh 410 grams each, so I've just reduced the weight of my tyres by over half a kilogram! No wonder they feel lighter and more responsive. Going from 75psi to 90psi thus far doesn't seem to have changed the comfort. The only thing now I'm a tad nervous about is that I used the existing tubes. Because of the weather I couldn't be bothered walking up to the LBS to get replacements. They're also Cheng Shin (they seem to retain pressure OK) but the marking said 700x35-43 so they're a bit over-sized for the 700x32s. They seemed to go in OK but I'll get some new tubes as spares. What are the odds of a pinch flat? Am I asking for trouble? -- A: Top-posters. Q: What is the most annoying thing on Usenet? |

The only advantage to using the smaller size tube is that it weighs less. If you got the tire on without pinching the tube or catching it under the bead you're all set. _ Booker C.

The only thing to watch out for is the tube folding or creasing upon itself--so make sure you put a little air in it before you tuck it into the tire, then install the second bead, put a few more pounds in the tire, and bounce it a bit to seat everything before pumping up to full pressure. BTW, Cheng Shin makes a whole range of tires and to be sure, some of the "standard issue" ones can be a bit crapola--but I've found some real gems. I've put close to 1500 miles on the Nashbar Prima Plus Kevlars I bought a few months ago, and they're holding up great! One pinch flat--not the tires' fault since I didn't check the pressure before one ride. The ride is quite excellent and supple and you can't beat $10 for a utility tire! When I have 20 bucks or so per wheel to blow, I'll of course look for some Vredsteins or similar on sale, but at the lower price point, gimme Cheng Shins! |

Aren't I clever? :-) I put in just enough air for the tube to hold its round shape rather than collapse like a dead worm and fall out of the tyre before I got everything into place and it all came together like I'd planned it. then install the second bead, put a few more pounds in the tire, and bounce it a bit to seat everything before pumping up to full pressure.

I paid US$29 each for the Fasgrips and I'm more than happy even at this early stage. If the tyres last me a year or more then I'm happy to pay a little extra for seriously good tyres. I mean, $10 or $20 per year is not exactly a deal buster in the greater scheme of things. -- A: Top-posters. Q: What is the most annoying thing on Usenet? |

I wish I could get a year out of a tire. On the rear, I'm happy to get two months before it starts showing threads. -- terry morse Palo Alto, CA http://bike.terrymorse.com/ |
