OEM tire replacement options

So I have the stock OEM 18 inch wheels and tires on my M3.

I'm looking for replacements for just my rear tires. I have a few questions on options:

1. I know it's not preferred, but how bad is it for me to run different tread tires on the front and back? My front PS2 have plenty of life left, but let's say I run a different tread from a different brand in the back. What are some downsides? Is it simply a difference in rates of wear?


2. If number 1 is not preferred, I'm looking to expand out different width sizes in the rear. What other size combos can I run for front and rears without rubbing? I noticed there may be more options for tires narrower/wider than 265 40 18 such as 255 40 18 and 275 40 18

thanks.

Definitely not recommended to mix. Every tire has a little bit of it's own 'personality' in how it handles. For example: How much slip angle does it take to generate max grip? How does it respond to different temperatures? How does its wet traction compare to its dry traction? How fast does it respond to a change in direction?

Sometimes the mix is not that noticeable, but other times it can give some strange or unsettled handling feel. It tends to be more noticeable the better handling the car is (obviously very good in the case of the M3), and the more advanced of a driver you are.

If you did mix, you would be best advised to use another max performance summer tire with similar tread pattern and hope for the best, but again, 4 tires of the same type is always preferred.

What about sizes for 255 or 275 be okay in the rears?
