Hi,
Why are fine cracks in the tread rubber a problem ?
The rubber has hardened somewhat I guess so somewhat
less grip, but if the carcass is fine whats the problem ?
I guess if the sidewalls have hardened it won't roll as well, but
if they are thin good rolling types will it make much difference ?
According to Sheldon Brown "
Cracks in the tread are harmless."
Why needlessly change a tyre for such tiny cracks ?
They are tiny and appear to be very surface only.
There is loads of tread and life left in that tyre.
rgds, sreten.
S.B. :
" Many cyclists waste money replacing perfectly functional tires
simply because they're old, or may have discolored sidewalls.
If you just want new tires because the old ones look grotty,
it's your money, but if you are mainly concerned with safety/
function, there are only two reasons for replacing old tires:
- When the tread is worn so thin that you start getting a lot of flats from
small pieces of glass and the like, or the fabric shows through the rubber.
- When the tire's fabric has been damaged, so that the tire has a lumpy,
irregular appearance somewhere, or the tube bulges through the tire.
