Bike tire size question

I should get a couple of them for the tires. I'm going to buy two tires. Unless you are riding your bike off-road in rather heavy terrain I would suggest you use a 26 x 1.25" such as http://www.nashbar.com/profile.cfm?c...to%2026x1%2E75 Sheesh...that's almost BALD. Prolly good for you and your rides but I do want some tread. It seems like a good idea to have matching sizes, front and rear which is why I want 1.75 or 1.95 I like the tube though. On pavement: bald-good; pattern-bad. Even on mild off road stuff such as packed gravel or dirt bald is no impediment. Well, for better or worse, I ordered two tires....both Cheng Shin cheapos... Sold by: Niagara Cycle Works1 "Cheng Shin C783 City Tire 26 x 1.50 Wire BW" Misc.; $6.78 and 1 "Cheng Shin C215 Street Tire 26%1A x 1-3/4" Wire Bead BW" Misc.; $6.36 I also ordered two tubes... 2 "Standard Tube (Schrader Valve) -26 x 1.5 - 2.2" Misc.; $4.99 My challenge now is to do the replacements myself. Doesn't look too complicated. twitch |

Bike tire size question
On 3 Jun 2008 15:51:08 -0700, Twitchell
may have said: In article , Werehatrack says... On 3 Jun 2008 13:51:59 -0700, Twitchell may have said: I'm ordering some tires for a bike but some of the sizes are in fractions (1 3/4) and others are in decimal (1.75) Is there a difference? There sure is! The rim is 26 x 1" (outside diameter) and have been told here that it will take a 1.75" width tire. It currently has a tire that says 26 X 1.50 A 1" wide rim (outside measure) of typical designs will easily support anything from 1.50 to 2.00" sectional size. It is not unusual to see tires beyond that range installed on such a rim, and it usually works well enough for the average rider to have no problems. For more extensive info on bike tire sizes, see http://www.sheldonbrown.com/tire-sizing.html Both of you.... Would I be safe in ordering: Cheng Shin C1027 Raised Center Tire 26 x 1.95" Wire Bead BSW http://www.amazon.com/Cheng-Shin-C10...532851&sr=1-64 Safe, yes. Advisable; not so much. There's way more tread knobbiness on there than you need, and it's probably going to buzz a bit. or Cheng Shin C215 Street Tire 26 x 1-3/4" Wire Bead BW http://www.amazon.com/Cheng-Shin-C21...532851&sr=1-71 Will Not Fit! This tire is made for a different diameter of rim than what you have. Note that in the extended information one says 559 and the other says 571; those two numbers are the rim diameter in millimeters. It has to match the rim diameter of your bike or the tire will not fit. Since we already know that your bike has decimal-size tires now, we also know that it has 559 wheels; no question of it being anything else. or maybe even 26x2.125, Raised Center, Black, 40psi, Tire http://www.amazon.com/26x2-125-Raise...33152&sr=1-138 Better than the first, but not what I'd buy myself, which is this: http://www.amazon.com/Tire-Pyramid-2...2552465&sr=1-1 Alternate link: http://tinyurl.com/5mnb34 That's a 26 x 1.50 city slick tire which I've had good results with. Do inner tubes come in sizes like tires or is it one size fits all? They are specific to an extent, but when you have two sizes to choose from with close or overlapping specs, pick the one that has the larger high-end to its range of appropriate sizes. For instance, with a 26x1.50 tire, if the choices available are 26x1.0-1.75 and 26x1.5-2.25, you are generally better off with the 26x1.5-2.25. Remember: fractional and decimal tire sizes are DIFFERENT, they are used on wheels that have a different diameter, and they don't interchange AT ALL. 26x1.5 is NOT the same as 26x1 1/2. In math, they would be; this isn't math. One other thing: there are two types of valve used on bike tubes; Presta and Schrader. Schrader valves are what you are used to; they work like the valves on a car wheel. Presta valves are different; they are skinnier, and they have a locknut on the end of the valve core (which sticks out of the end of the valve). UInless the bike you have is already equipped with prestas, or you like having to fiddle with extra steps when airing up a tire, stick with Schrader-valve tubes. Most non-bike-shop sources will generally not have Presta-valve tubes, but Amazon's marketplace suppliers have both. I should get a couple of them for the tires. I'm going to buy two tires. Sounds like a plan. -- My email address is antispammed; pull WEEDS if replying via e-mail. Typoes are not a bug, they're a feature. Words processed in a facility that contains nuts. |

As we explained to you, fractional sizes (e.g., 26 x 1-3/4") use a different rim diameter that decimal sizes. Your bike has rims with 559 mm bead seat diameter. The 26 x 1-3/4" tire you ordered needs a rim with a 571 mm bead seat diameter. The Niagara web site states: *Note: This is NOT the same diameter as a decimal tire size, such as 26" x 1.75"* Art Harris |

Anyway, it's on it's way and since it's only $6.36, I'm not being killed. Any advise on my front forks? They're 1994 Manitou Eastons. Thom sent me a manual in PDF format. I couldn't tell by looking but apparently, they move up and down and the manual says they should be taken apart and reoiled EVERY THREE MONTHS....you can't be serious. .....so I looked at the manual to see how to do it. Seems like a lot of work just for some bike forks and to do it every three months seems excessive. twitch |
