What does 700x45c mean?

The second measurement type (700x45c) is a 45 mm wide tire that also fits on a rim with a 622 mm bead seat diameter, the 700c is an old French sizing nomenclature based on the final external diameter being 700 mm for width class of tire (e.g., a, b, c widths).

What does 700x45c mean on a bike tire?

Breaking it down, we have: “700” = the nominal diameter of the tire. “x” = just means 'multiplied by' “45” = the nominal width of the tire (when you stand facing the front or rear of your bike and look at the tire) “c” = this is a tire width code, using the historical French system.

What does 42c mean?

The c number, as in 42c is a marketing number, so it tells you what the manufacturer thinks you want to hear, which is probably going to be fairly accurate when interpreted as millimeters. Tires also have ISO numbers, and sometimes a tire will even list two widths, i.e. for the casing and the tread.

What does the C stand for in 700C wheels?

700C tires

The "700" refers to the rough outer diameter of the tire, although the actual outer diameter will vary greatly, depending on the type of tire and tread pattern. The "C" means NOTHING; it does not stand for "centimeters." Think about it--a 700-centimeter tire would be HUGE, over 21 feet tall!

Is 29er the same as 700C?

29" (ISO size 622) is actually the same rim diameter as 700C, although most 29" tires will not fit 700C road rims because they're too wide.

Review: WTB Riddler 45C Gravel Tire

Can I put 29er tires on 700C rims?

700c is the same rim bead-seat diameter ETRTO-622 and the same as road 28" and the same as MTB 29" (29er). So yes, you can fit 29" tyres on a 700c rim (of course, subject to the tyre and rim width compatibility What is the maximum or minimum tire width I can fit on my bicycle).

Is 622 the same as 700c?

The standard modern road bike wheel has an ISO diameter of 622 mm and is referred to as 700c (makes sense, right? /s).

Is 27.5 the same as 700c?

That's changed over the past decade, so the majority of modern mountain bikes now come either with 29in or 27.5in wheels. These two sizes are equivalent to 700c and 650b wheel sizes expressed in the European ETRTO wheel size designations and have the same bead seat diameters.

What is the difference between 650b and 700c?

The difference between 650b and 700c is the diameter of the rims. 650b wheels measure 584 mm in diameter. 700c wheels measure 622 mm in diameter. 650B wheels are 38mm (about 1.5”) smaller than 700c.

Is a 28 inch tire the same as 700C?

28”/700C/29er

The tyres can differ, but the 28”, 700C and 29er are all the exact same rim diameter. The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches. This is the most common wheel size, so look out for familiar markings (such as 28x1.

Will a 27.5 tube fit 700C?

However, tires that are close in bead diameter may use the same inner tube. For example, an inner tube for an ISO 630 tire (27-inch) will also fit an ISO 622 (700c) tire. The inner tube should also match the tire width, but, because inner tubes are elastic, one inner tube may fit a range of tire widths.

What is the wheel size of a 29er?

29er rims have an interior diameter of 622 millimetres (24.5 in) and the average 29" mountain bike tire is (in ISO notation) 59-622 – corresponding to an outside diameter of about 29.15 inches (740 mm).

Can I use 29er wheels on a road bike?

Like Shiggy said. If you have a normal road bike with 700c rims, you could take the wheels off and slap some 29 x 2.1 tires on them, no problem. (Road bike rims are narrower, but the tires will still fit). Of course, you won't be able to get the wheels back on the bike...

Which is faster 27.5 or 29er?

27.5 in. wheels have faster acceleration while 29ers are more efficient on longer rides. Smaller wheels accelerate faster than larger wheels. This is due mostly to where the weight of the wheel is distributed.

Can I use 27.5 wheels on a 29er frame?

Building up a set of 27.5+ wheels is a great way to turn your 29er into a dual-use rig ready to handle everything from XC racing to adventure riding to fast, technical descending.

Is 35c the same as 35mm?

35c means that the tire is roughly 35mm wide.

What does 700x35c mean on a bike tire?

700x35c is the dimension of your bicycle tire, as measured using the 'French system'. Breaking this down, 700 is the nominal diameter of the bike tire in millimeters. The next number, 35, is the nominal width of the tire (again, this is measured in millimeters).

Is 40mm enough for gravel?

If you're new to gravel tires, pressure is key. I'm normally 80-85 psi in 25 mm tires and my 40 mm tires are perfect in the 28-33 psi range. They feel rough on anything but pavement near 40 psi. Yes - the right tire size.

What does 700x23 28c mean?

“700” is the overall diameter of the bike tire, measured in millimeters. “28” is the width of the tire, again in millimeters and “c” refers to the width code of the tire (like you'd see when you look at your bike either from behind or in front).

What is the difference between 700x25 and 700x25c?

All those tire sizes you list are the same. If there were different prices for the "700x25" and the "700x25c", it's because there was some other difference between the tires, like model, threads per inch, bead type (wire or kevlar), etc... The other widths were designated 700a, 700b, 700c... you get the picture.

What does 700x23 25c mean?

Some manufacturers (e.g., Specialize) offer two width measurements (e.g., 700x23/25c) to indicate that the carcass is 25 mm wide, but that the tread patch is equivalent to a 23 mm tire.
