Thanks for the great thread OP.

I recently purchased a BMW F30 LCI that has 225/50R17 tires. Is this the original size? I was looking at some F30 brochures online (please see attachment), and it seems like it could potentially be 225/55R17s.

Secondly, aside from Primacy, can you recommend any other tires? Just wondering if there is a more wallet-friendly option if my priorities are handling>fuel economy>comfort. I don't drive this car outstation and seldom ferry more than 1 passenger.

Thank you!

Between MC6 v RE0003, I am leaning towards RE004. Is that a good choice?

MC6 is more of a touring tyre, although marketed as UHP.

RE004 is more performance-oriented. Sacrifices comfort for more grip.

Both are good tyres. 1 is a slightly extreme performance tyre while the other is more of an all-rounder.

I am going with MC6 in the end after going through OPs blog. It seems like MC6 is better “balanced” for a lack of better word.
