Hi can someone advise what tyres should be fitted to my car I have the 18"10 spoke alloy, these have 245 40 18 all round thanks

I think your rear tyres should be wider than your front ones if it's a sport model you have!

You should have 265/35/ZR18 on the rears.....

Thats what I thought probably previous owner has put 245 40 18 all round for cheapness, will this affect the car is anyway? Should I change rears to the recommended size

If you do decide to leave them alone, it would be worth a quick call to your insurance company, as the spec is no longer standard.

Funny buggers in the event of a claim, some of them.

Are they ok to leave alone or will this alter ride comfort etc

I would change the rears... Suppose to be 265/35, the rear alloys are wider so the current tyres will be stretched.

I would agree with that.

But I'd first remove a rear wheel and check it is in fact a 9J wider rim. It should be stamped inside the wheel.
If a previous owner changed the alloys, they could have gone for 8J 's all round to save money and therefore fitted all 4 tyres the same.

^ agree with the above, it could be more than just the tyres that are wrong.

The car is a sport from the factory so I wwould guess the wheels would be original I will be able to look and tell more once I pick it up on friday from dealership. I think someone has put the wrong size on to cut costs

 

[t-dawg1]

Why are you buying it from the dealer with wrong tyres on it? I'd get the dealer the change them for you as part of the purchase deal
