tyres

[Frosties]

I had to have a valve replaced and the guy said my tyre was getting squred off or something like that, what of an issue is this?
The tread iss ok and I have not noticed anything whilst riding

Hiya fella, see piccy below for a squared off tyre

It depends on the brand/profile of the tyre and sometimes also the bike. When pointy profile tyres square off the handling can go off big time. The front tyre develops a shoulder which can make the steering feel vague and slower to turn in and if you push on past, it feels like the front is going to fold when cornering due to riding from a flat surface, over the edge and then a sudden increase in lean. The rear being squared off will increase the effect of a slow turn in developing into a sudden drop in. Squared off rears can also cause a high speed weave.

Tyres squaring off is normally down to a fair bit of motorway commuting, only gunning in a straight line or tyre pressures

Hope this helps fella
