245 Tires at the back.

[marlboroplug]

I noticed my car has 245 tires front and back. Should i leave it as it is or should i get 275 at the back? 2015 F06

Are your wheels the same width, or did somebody put the same size tires on staggered wheels?

I have a feeling wheels are staggered, car is RWD and the rims should be OEM. Will have to check later since the car is not with me at the moment. Panel on the driver side column said 275 at the back.

Have you decoded your VIN? If yes, what is your wheel style (or wheel style number)? Without knowing what wheel is being discussed...the forum is in the dark. We don't know if you have a square or staggered setup. Help us help you better...give us enough info to work with.

Ah...thanks for the update.

That is a staggered set of 20" Style 373 wheels that came from the factory with

• 245/35/20 (front tires)
• 275/30/20 (rear tires)

So either the previous owner or the vendor changed the rear tires (or did they change the wheels, too?).


style 373 wheels & 20" summer tire run-flat recommendations: (see wheel specs below)

You should definitely measure the wheel widths before just having somebody put on wider tires.

I will certainly do so. Thank you for your help.

Thank you for your thorough reply, I really appreciate it. I will take some quick measurements just to make sure, and then get some 275’s at the back.

If you dismount the wheels…you can also just check the BMW part numbers & specs which will be located on the backside of the wheel’s spokes. That is another way to verify which size you have.

You can see what the part nbrs & specs are in the pics posted above from the part database for the wheels. And you can also see an example of the rear wheel’s part nbrs and wheel spec info that you should find on the back side of the spokes in the pics below (looks like the last 7 digits of the BMW part nbr is used instead of the complete 11 digit part nbrs. This is normal…sometimes its the complete 11 digits, but sometimes only the last 7 digits are given:

Good idea. Just looking at the wheels without taking them off i can clearly tell the rim is too wide for the tire as it sticks out. I will check the part number like you said and change them later. Thank you.
