How wide are my tyres?

Tyre width is a hot topic at the moment. There are arguments as to what tyre width is fastest, which width offers greatest grip and also issues with fitting certain tyre sizes into specific frames and forks.

A major factor that needs to be considered when choosing your tyre size is the width of the rim and how this affects the tyre. At Hunt wheels we offer wider rims which give a number of benefits including greater stiffness and improved aerodynamics. However the biggest advantage is the effect the wider rim has on the tyre. Using a wider rim offers the tyre much more support and gives a much rounder tyre profile when compared to a narrower rim profile. The benefit of a rounder tyre is greater and more predictable grip in corners and better alignment with the rim which improves aerodynamics. Using a wider rim also effectively increases the tyre size without the extra weight from moving up to a wider tyre.

A good example is a 23mm Schwalbe One Pro tyre fitted to our Race Season Aero Wide wheelset which has a 19mm internal width actually makes the  tyre 25.3mm wide. So effectively by fitting a 23mm tyre to our Aero Wide rim you are making it perform like a 25mm tyre in terms of stable cornering, improved grip and lower rolling resistance whilst saving 40grams per per pair in weight. The 23mm Pro One tyre measuring at just over 25mm also aligns perfectly with the Race Season Aero Wide rim creating an even smoother aerodynamic profile (as shown in the image below) no unstable light bulb shaped tyre here!

The width increase is even more noticeable with our carbon wheelset. Our 55Carbon Wide Wheelset has an internal width of 21mm which increases a 23mm Schwalbe tyre diameter to 26mm. If you are more of a long distance rider and comfort is a priority then why not fit a 28mm Schwalbe One Pro tyres which measure in at 29.3mm on our MasonxHunt 4 Season Disc wheelset and 31mm on our 38 and 50 Carbon Disc wheelsets. Imagine all that grip when you have to haul your powerful disc brakes on at short notice, plus loads of rough road munching comfort.

We have created a tyre width guide which lists all our current wheelsets and the actual measured tyre sizes. This guide will help decide which the best tyre size will be for you in terms of both performance and bike clearance.

    Great article..

    With this in mind may I please change my 25mm Schwalbe pro tubeless option to 23mm on my aerolight disc order ? As I understand there is a delay with 25mm? However I’m informed you have both 23mm and 28mm in stock ready to be fitted?

    Thanks
