Recently replaced the rather ancient rear Toyo 18's on my C3 with a new pair of Michelin PS 5's (and all ready to go on the rear-end of the car).....once front end suspension/steering overhaul is completed.
Stock size tyre (215/70/15 for early C3) or 225/70/15 (later C3) relates to 26.9" diameter for early cars and 27.4" diameter for later cars.
My ancient rear Toyo's were 285/40/18 with 27" diameter This size is proving difficult (and expensive) to find currently. I've bought 275/40/18 sized tyres. These are currently relatively common place. used by many car brands and offered by multiple manufacturers. Diameter of tyre drops to 26.7" diameter a mere 1.5%/2% - a minimal change.
