Going up in tyre size??

Post by Gidanski »

As per thread title I am wondering what the effects of going up in tyre sizes on my NC31 would be. Bike needs new tyres for RWC and am looking at all options.

Thinking of doing the following

Front Rear
110/70-17 > 120/70-17 140/70-17 > 150/70-17

I am aware of the obvious speedo calibration error. But from what I have read online if the tyres are designed for the rim then as long as the tread isn't a V shape then all that will happen is sharper lean in?

It's best to do that as you don't get anymore "grip" from a bigger tyre only a bike that handles worse.

120 at the front will result in an unstable front end from my experience, but 150 at the rear is fine.
