I recently purchased a '15 C300 4MATIC with the Sport package and noticed the tires are 245/40R18 all around instead of the staggered OEM sizes. The front tires should be 225/45R18. Is this an acceptable setup and any handling issues or anything else I should be concerned about? Tires are mounted on the factory AMG wheels.

 

As long as it drives fine and does't rub you should be fine. I actually rather have it that way so you can rotate the tires.

 

having a squared tire set up is okay but are the wheels squared as well though, is the question, so you can do full tire rotation.

 

That's a great question. Will have the wheels off on Monday and I'll know then. So it sounds having the 245/40 up front really shouldn't be an issue with steering or handling?

 

Hey RunawayOneSix, did you ever find out what were the size of your wheels rims? I'd imagine something like 18x8 on both fronts and rears right?
