Tyre Size Guide
Tyre Size Guide
Whether you are replacing a worn out tyre or want a performance upgrade, it is essential that you choose a tyre that is compatible with your bicycle as well as your riding style.
To find out which size tyre you will need have a look at the sizing information on your existing tyre. You can find this information on the side wall of the tyres, either in coloured print or embossed in the rubber itself. Both rim diameter and tyre width are shown in the size info.
Road bike tyre sizing
700 x 23c
A standard 700c road bike rim with a 23mm tyre width.
MTB tyre sizing
27.5 x 2.3
A 27.5” mountain bike rim with a 2.3” tyre width.
You will notice that road bike tyres tend to me measured in metric units while mountain bike tyres use imperial units.
What Size Tyre Do I Need?
Ypu need to knnow your wheel size and tyre width when chosing a replacement tyre for your bike
Wheel Size
Tyres are made to fit specific wheel sizes, so you need to know what size the wheel on your bike is.
The easiest way to do this is by looking at the tyres on your bike. On the sidewall you'll see a combination of digits such as:
700 x 28c (road bike wheel) or 27.5 x 2.4 (mountain bike wheel)
It’s the first figure that shows the diameter of the wheel or the wheel size.
The next figure is tyre width which is the other measurement you need to know.
Tyre Width
Inner tubes are designed to fit a range of tyre widths, so the next thing you need to know is the width of your tyre.
This is shown in the second number that’s printed on the side of the tyre.
700 x 28c (road bike wheel) or 27.5 x 2.4 (mountain bike wheel)
When choosing an inner tube you need one with a width range that covers your tyre width as well as exactly matching the size of the wheel. See the tables below for examples.
Note: Sometimes metric sizes are shown as c instead of mm. This is just a different way of saying the same thing. A 25c tyre is the same width as a 25mm tyre.
Traditional and ETRTO sizing
Sometimes the sizing info is listed in two different ways; the traditional sizing method shown above and ETRTO sizing which lists the tyre width first and the rim diameter second. The rim diameter size is measured differently with ETRTO, for example:
23-622
This is a standard 700c road bike rim with a 23mm tyre width, which is the same size as 700 x 23c.
We recommend that you use the traditional sizing method wherever possible as most tyres that we stock use this system.

What are the different types of bike tyres
While road, mountain and hybrid tyres have their own specific differences there are some features that are common to all tyres.
- Clincher tyres - most bike tyres have a bead which hooks onto the rim to keep the tyre in place. Traditionally this bead is made from wire which is tough but heavy. Premium tyres use a folding Kevlar bead which is equally as strong as wire but is much lighter weight.
- Tubeless tyres - while regular clincher tyres require an inner tube to keep them inflated tubeless or tubeless ready tyres form an airtight seal with a compatible rim so you don’t need an inner tube. These are most commonly found on mountain bikes as they can be run at lower pressures without risking punctures.
- Tubular tyres - These are specialist road bike tyres that have the tube built into the tyre and are then glued onto a compatible rim.
Frequently Asked Questions
What size tyre do I need for my bike?
Look at the side wall of your tyre for any printed numbers indicating the size and width.
How do I know my bike wheel size?
The easiest way is to look at the side of your tyre. The size and width are printed on the tyre.
How do I choose a bike tyre?
Once the compatible size is known, choose an appropriate tread for the conditions you ride in.
Can I fit wider Tyres on my bike?
Look at your fork and frame where the tyre passes through, measure any available clearance to gauge what width tyre will fit.
Is a 28 inch tire the same as 700c?
700c wheels have a diameter of 622mm. While most 28 inch tyres are for a 622mm wheel, some are not. Check the ETRO number on the sidewall to confirm.

Maxxis Tyre Guide
Maxxis Tyre Guide
Maxxis are perhaps the most popular MTB tyre brand with tread patterns and tyre technologies that are perfectly suited to each mountain bike discipline. Maxxis road tyres build on this technology to offer cutting edge performance. See the range of technologies that give their bike tyres a performance edge.
Protection
Double Down
Double Down is a dual ply casing designed specifically for enduro tyres. A butyl insert sits above the bead within the two ply casing. This offers extra strength where the bead meets the tyre for extra stiffness where it’s needed most as well as reducing the chances of burping. Double Down tyres are 15% lighter than the equivalent Downhill tyre.
Silkworm
This breaker layer sits under the tread and offers improved puncture and tear resistance. Silkworm features on selective Maxxis tyres.
SilkShield
This puncture and tear resistant layer is incorporated into the casing of the tyre and runs from bead to bead. As well as offering under the tread puncture protection like Silkworm, SilkShield provides an additional level of protection for sidewalls.
EXO +
Maxxis EXO+ construction features a layer of EXO protection with an additional layer of SilkShield, the two best puncture protection materials from Maxxis. Combined, these materials improve tread puncture protection by 27%, sidewall durability by 51% and resistance to pinch flats by 28%.
MaxxShield
Combining both a K2 (Kevlar Composite) under tread layer with SilkShield bead-to-bead protection, Maxx Shield represents the ultimate in flat protection.
ebike
Maxxis eBike tyres are designed to meet European ECE-R75 standards, guaranteeing performance and reliability for additional cargo capacity and increased speeds electric bikes can offer.
EXO Protection
EXO Protection tyres feature a cut-resistant and abrasion-resistant layer in the sidewalls. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tyre remains unaffected. Choose EXO Protection for exceptionally rocky trails where the chance of sidewall cuts and abrasions is high.
Butyl Insert
An extra piece of butyl rubber that extends from the bead of a downhill tyre up into the sidewall. Featured in Maxxis DH tyres, the butyl insert helps prevent pinch flats, protects the rim from hard hits and adds sidewall stability.
Rubber Compounds
3C Triple Compound Road
Triple Compound road technology utilizes three distinct silica compounds in different locations within the tread of the tyre. The centre compound is optimized for exceptional tread wear and low rolling resistance. The progressively softer shoulder compounds provide increased grip while cornering.
3C Triple Compound Mountain
Maxxis 3C Triple Compound mountain technology uses a harder, longer lasting base layer and two progressively softer top layers in order to optimize traction and stability. Maxxis offers three different configurations of our 3C Triple Compound mountain technology: MaxxSpeed, MaxxTerra and MaxxGrip.
3C MaxxSpeed
MaxxSpeed is the fastest rolling 3C tyre. Used primarily in cross country and xc race tyres, the two compounds in the outer layer are specially formulated to reduce rolling resistance and optimize tread wear and traction.
3C MaxxTerra
An intermediate compound configuration used in select mountain tyres MaxxTerra is the 3C compound that is ideal for trail and enduro riding. 3C MaxxTerra is softer and offers more traction than 3C MaxxSpeed, yet provides better tread wear and less rolling resistance than 3C MaxxGrip.
3C MaxxGrip
This is the grippiest Maxxis 3C compound.3C MaxxGrip uses the softest rubber compounds to offer the ultimate in grip and slow rebound properties for unparalleled traction in downhill applications.
Technology
Bead
There are three different types of bead on Maxxis tyres. Wire beads are strong but are not so flexible. Foldable beads are made from spun aramid or Kevlar fibres. These are also strong but are lighter weight than wire as well as being easier to transport. Carbon fibre beads are flexible with greater strength to withstand the forces exerted by a high-pressure road tyre.
Casing
Single-Ply Casing - One layer of nylon wrapped from bead-to-bead. A single ply casing conforms well to the terrain and is lighter weight.
Dual-Ply Casing - Two layers of casing material are used from bead-to-bead, providing additional protection and sidewall stiffness for enduro and downhill applications.
Threads Per Inch
The number of threads that cross through one square inch of a single ply of the tyre's casing. Lower TPI gives better puncture, cut and abrasion resistance but is heavier. Higher TPI conforms better to the terrain, offering a smoother, more comfortable ride while reducing the weight of the tyre.
Tubeless Ready (TR)
Tubeless tyres provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tyre; and less chance of flatting since there is no tube.
Liquid sealants should only be used in the following types of tyres: Tubeless Road, tubular, and tubeless Ready. The use of liquid sealants in any other Maxxis tyre will void the warranty.
