I run a pair of Conti Grand Prix 4 seasons tyres on my road bike.
They have lasted about 7-8 years easy as I do not ride as a pastime.
Only to commute sometimes.
Now the side wall meshing has started to fray altho the treads are still
strong as ever.
Recently however I got a pinch flat and changed the rear tube....within
a few days I got a pinch flat again. (I always ride with at least 100PSI
tyre pressure although sometimes I am lax in re-filling the tyres)
I this a sign that the tyres need replacing?
