How to check your current tyre size?

Take a look at the sidewall of your current tyres and you’ll see one or two sets of figures;

One is the traditional size like 700x28c or 27.5x2.2. The first figure is the tyre diameter(size). The second is tyre width. Note: road bike sizes are in mm, MTB sizes are in inches.

The other set of figures you may see is ETRTO sizing like this 28-622. The first number here is tyre width while the second number relates to wheel diameter.

Here is a comparrison chart for traditional and ETRTO sizing to help you choose the correct tyre size.

Will this tyre fit my wheel?

Your new tyre must be the same diameter as your current one (to fit your wheel rim).

Then, you need a choose a tyre which will fit your frame.

Road bike tyres are generally 21 – 28mm wide

MTB tyres can range from 1.5”-5”

To make things complicated road tyres are measured in mm, while MTB tyres are in inches.

How wide is too wide

You want to leave at least 4mm clearance between your frame and tyres to prevent rub and allow for mud clearance.

Measure the following areas on your frame:

Fork crown (top)

Brake calipers (make sure you squeeze them)

Chainstays

Seatstays

Subtract 4mm and you’ll have the maximum width your frame can handle.

Continental Tyre Guide

 

Continental Road Bike Tyre Guide

With over 100 years of manufacturing experience, Continental road bike tyres have been tried and tested at the very highest level. See the range of technologies that give their clincher and tubular road bike tyres a performance edge.


Compounds

Black Chili Compound

Black Chili is Continental’s premium rubber compound for both road and mountain bike tyres. It offers more grip with less rolling resistance and even lasts longer than other rubber compounds.


Pure Grip Compound

Pure Grip is a performance rubber compound that sits just below Black Chili. An Activated Silica rubber compound, Pure grip offers excellent traction, is also long lasting and highly durable. Used on both road and mountain bike tyres, Pure Grip is produced in Continental’s Chinese factory.


Tyre Types & Protection

PlusBreaker

These tyres offer the highest level of puncture protection against objects piercing the tread. Plus Breaker is a layer of special highly elastic rubber sits just underneath the tread. This successfully stops all types of foreign objects from getting through to the inner tube below. Even a drawing pin can’t get through the PlusBreaker layer.


PolyX Breaker

PolyX Breaker is a densely woven Polyester fibre layer that sits beneath the tread of the tyre. The polyester fibre layer is tightly woven crosswise and is extremely resistant to foreign objects penetrating through the casing. This puncture reducing technology does not adversely affect rolling resistance.


Vectran Breaker

Vectran breaker represents the pinnacle in puncture protection. Highly resistant to puncture and cuts, Vectran breaker doesn’t slow the tyre down. Vectran is a liquid crystalline polymer (LCP) that is spun from Vectra liquid polymer and processed into a multistrand thread. Vectran has an enormous tear resistance at a very low weight and offers the ultimate under-the-tread protection.


DuraSkin

DuraSkin is an ultra-lightweight cut resistant sheath that wraps around the tyre casing. Designed to protect the sidewalls and tread from actual cuts and slashes on the road, this technology is found in all Gatorskin tyres. DuraSkin tyres stand out with their brown sidewalls.


Hardshell

With a wider PolyX breaker layer combined with DuraSkin sidewalls, Hardshell-ProTection offers outstanding puncture protection. The three-ply layer with 60 TPI carcass covers the entire tyre and makes it a real bastion against urban detritus. Hardshell tyres are the flagship puncture protection racing tyres.


Supersonic

Lightweight for maximum acceleration, Supersonic tyres are ideal for track and time trials.


NyTech Breaker

Sitting between the SafetySystem and PolyX Breaker, NyTech offers more effective puncture protection for performance tyres. The Nylon fabric is highly resistant to cuts and punctures but offers low rolling resistance and reduced weight.
