Scirocco Central

You should have the Cambelt changed, and it’s well worth having the water pump done at the same time.
If the Cambelt fails, it could cause a whole bunch of damage so it’s not worth neglecting.

My R is the same age and I had my water pump and cambelt changed last summer.

ZR is the older way of saying it’s a high performance tyre capable of higher speeds than 149mph. The R bit is retained as it means it’s a radial tyre. Your new tyres probably have the letter later in the tyre code e.g. W, Y etc.
