Upsizing Tyre Size

Not having done it myself I thought I would leave it to others to reply but you are probably feeling ignored!

I have done it with other bikes so my first question is WHY? There is no performance benefit to be had but you will subtly change the handling characteristics and maybe increase your rolling resistance too. You may find turn in needs a tad more effort but profiles vary between manufacturers and tyres so it is another variable. The main reason to do it is because you prefer a chunkier look. Just recognise it is aesthetic and not an 'upgrade' in any meaningful performance sense.......unless you have spectacular engine mods to feed.

Just remember clearance issues and the slight changes in circumference will minimally impact speedo and gearing .....but again, probably not enough to notice.

I leave it to others to argue for particular brands and sizes.

 

Don't we all!!

 

", just because you have a 50% larger contact patch, you will not suddenly get 50% more grip from your tyre. If you imagine trying to push a house brick across a table, you will need the same amount of force to move it whether it is placed on its widest or narrowest side. That is because the weight of the brick remains the same, and the amount of friction remains the same too, it is just spread over a larger or smaller surface area depending on which side the brick is in contact with the table. Grip works in very much the same way, regardless of the size of the contact patch."

MCN dont like the notion see below

I wouldn't change tyre sizes. I'd stick to manufacturers specified sizes. They are what they are for a reason.
