Coker tyre - life

I wonder if they changed the rubber in the different batches of Coker
tyre?

I'm sure my first Coker tyre lasted over 2000km before all the knobs
were gone.

My second Coker tyre was almost half-worn through after a day's riding.
All up it lasted just over 1000km I think. Most of that was on quite
steep riding during the Alps Unitour.

My third tyre lasted about 106km before I threw it way. The bead
snapped- I had to superglue it to the rim, and in the end decided it's
not worth the risk of blowing the tyre out in the middle of nowhere.

I'm on my 4th tyre now.

I don't know why I'm getting so much less use than you....I don't have
much side-to-side wobble when riding although I tend to use lower
pressure than most people. The roads here in NZ are pretty rough too.

Thats very interesting. I ride very much on grawel. Use 32 - 33 psi
pressure. Maybe tarmac destroying the tyre much quicker. I think as you
say it must be a difference in the rubber in the different batches of
tyres.

would have thought gravel would have worn it more... tarmac is
smoother....

Gravel moves when you turn where pavement grinds on the tire. I don't
know what my mileage is but I get one season before the belts show
themselves.

yeah but i would have thought gravel would pop it more easily, so once
the thread isnt as good, it would just pop it... but hell i'm proabbly
wrong

The tyre has less grip on gravel, thus less friction, thus less wear.

i guess that makes sense.... also if you want your tyre to last longer,
just inflate it as much as you can.....
