hi guys just bought a 2009 clc200 cdi sport yesterday shes a gem just have a query
front tyres are 225/40/18 and rears are 245/35/18 why are these different?? is that normal and if so why do they do this. many thanks in advance

You will find out what the correct tyre size should be in the handbook. Many cars have different sizes front and rear. You have the fatter shallower ones (245/35) on the rear and the slightly less fatter deeper ones (225/40) on the front. This seems as if it could be correct, with 18" wheels, the reason for these sizes will probably be looks (more agressive) and perhaps wheel arch clearance. I just don't know, but having 18" tyres will be more expensive to replace them.

Just found the same model as yours on a web site, technical details shows the same size tyres as yours. Still expensive though.

thanks for the info mate yeah cant look any data up in the manuals as car dealer has lost them at the moment hopefully should get them next week just thought it was strange having different sizes and wondered if there was a purpose for this rather than cosmetics ie. something to do with rear wheel drive

You must have staggered wheels witch would explain the different size tyres

The tyre wall depth on the fronts are less than those on the back. 85.75mm on the front as opposed to 90mm on the back.
