Hey can anyone tell me what tyre sizes are needed on BMW X3 M40i with 20" alloys?

I believe I have run flats on mine, and just looking to work out replacement costs

Cheers

What speed rating etc? I'm guessing Y

Also, any tyre recommendations if I were to get a replacement set? Run flat or non run flat?

Think mine are W.

They are RFT PZeros. I think they are ok for run flats. I will be changing mine soon. Like you, looking for any recommendations.

I am also toying with the idea of running all season tyres - any experience with them appreciated!

Front 245/45 R20 103W
Rear 275/40 R20 106W

This is on a 30d, not sure if a 40i would have higher speed rating or not.

Same as on my M40i
