so i have a 435i grancoupe x drive and i am looking to to buy used michelin pss tires from a friend. the tires are off of a m235i rwd.

The tires are 225/40/18 front and 245/35/18

Will these fit on my 435i? or will they be too small?

What size wheels are you running? Are they OEM?

I believe they're a little small, and wrong profile. Check tirerack.com for correct size.

i currently have the stock continental 225/45R18 91V

does the profile size affect the speedometer?

Right, your tires are 25.9" in diameter and his are 25.1" or 3.3% smaller and your speedometer would be off by that amount. It would also mean that your car would have about a half inch larger gap between the tires and fender and ride about a half inch lower.
