Is 700x38c bicycle tire the same as a 26 bicycle tire?

Answer 1

700C means 622 mm, 26" can mean anything from 559 to 599 mm, with the latter being quite rare. The wheels might fit, but if it's a rim braked bike there's no way the old brakes are going to reach the new rims. Current MTBs (which are 26"/559 mm) can usually take 700C wheels with narrow tires. But you need them to be either disc braked or to use an adapter plate to get rim brakes to work. 700C(622 mm) in a frame meant for 27"(630 mm) often work out just fine, but you might have to switch to something called long-reach brakes though. 27" was an old road standard, so that's a fairly common swap.

Answer 2

If your rim width on the interior is 13 or 15, then yes, the tire should fit, however if your rim width is 17 or above, it probably will not fit correctly and you could wind up with tire or rim problems. the 700 x 25c is designed for rim width sizes 13, 15, and 17, while the 700 x 23 is only designed for the size 13 and 15 width rims. Both tires share the same rim diameter of 622mm (Which is the 700 in the size) so only your width is affected with the switch from the 25c to the 23 If you arent sure which rim you have, you can measure the width from the inside of the lip to the inside of the other lip, for your issue, it should measure 13mm, 15mm, or 17mm respectively for size 13, 15, and 17. Be sure to measure the lips inside to inside, because if you measure from the outsides of the lips, you will not get an accurate measurement and your tire width will come out bigger than it actually is! Hope this answers your question!

Answer 3

There's really no way of telling. A "true" racing bike is intended for thinner tires, and usually have very little clearance by the fork crown and the (rear) brake bridge/seat tube, there might simply not be enough room for a wider tire.

A somewhat more relaxed race bike might have room enough for wider tires. Basically you'll have to check to find out. Once you've figured out which size tires you have now, just look at every place where the tire is close to a part of the bike, see how much space there is. Then it's fairly easy to estimate if the CX tire will fit or not.

Answer 4

No. 700C translates to a Bead Seat Diameter(where the tire contacts the rim) of 622 mm, and the most common 26 inch is 559 mm - there's no way you can make them fit reliably.

Answer 5

No. The 700 size series tires have a 622 mm Bead Seat Diameter, while the most common 26" (there are several different) use a 559 mm Bead Seat diameter.

Answer 6

It's a size designation. Also known as 28" or 622 mm. With a (fairly thick) tire on, the diameter is about 700 millimeters, or 28".
