IIRC I changed your cap and rotor when I did your clutch slave. Officially the interval is 12,000 on them.
Do you mean side wall, or in the tread? There is a repair that can be done on the tread which involves a length of rubber being threaded through the hole coated in adhesive, which is then trimmed back. It can't be done in the sidewall though.
Forgot about the fuel filter in my little list
I've got a couple of genuine Renault air filters if you want one
