Today my dad to the S to the dealership today to get new rear tires for free because we bought the car with oem tires that were worn out already. Today the put on Falken Ziex 512 tires with a size of 225/50/16. Is this size right for the rear or should they have put on 245/45/16?

It still has stock rims and we originally had stock tires.
BTW this is a used car dealership we bought the car from.

 

Check out the thread at the top of this forum. They gave him the wrong rear tire size.

 

you have made a mistake my man. 245's

 

Those cheap bastards at the dealership. They should have given you something better....that is a bunch of crap sticking you with the Falkens. You bought the car used? They made a at least a few thousand on you, the least they could do was give you some good tires.
