Hi everyone, I am looking for some help in deciding which tyre width to go for on my front wheel.
I would like to know at which speeds the wider tyre starts to cost you more watts.
I am currently running a 28mm tyre on a Parcours Chrono Max.
The tyre measures at 30mm and has a really clean fit with the width and shape of the wheel.
I tried a 25mm tyre on there which measured at 27mm.
The reason I ask is because when tine trialling I usually hold speeds of around 45kmh but during triathlon this is slower at between 36-41kmh.
Parcours suggest that with real world yaw angles the airflow attachment is better with the 28mm as the tyre fits the wheel better. My assumption is at the higher speeds the yaw angle will be less relevant. I also do not fancy changing tubules tyres every few weeks just to have the right width so I would like to go for the one that will be fastest all/ most of the time.
Thanks for your help in advance.
