Tires OEM BMW or FEDERAL

Just the loudest tires on planet earth. Boy do they grip through!

I just went from Federal 595 RS-RR (very loud but performed well on street and autocross) to their 595 RS-Pro (waaaaay quiter, I love these tires so far).

I also own a set of these, I can confirm. Fits my BMW very well as they used to make airplane engines, and these sound like a Messerschmidt prop plane.

Federal 595 RS RR

Wear earplugs. They're great.

Regarding the X3M - I have about 9 months and 6k miles or so dailying mine. It is firm but I don't believe it's as punishing as most reviews mention. The thing is a monster man. I don't know why anyone would need anything more in a daily. It handles easily as good as my RS3 did and maybe even less body roll despite being much higher CoG and the RS3 didn't roll much either. It feels direct and definitely feels rear driven.

Federals will be really noisy after a few thousand miles. Almost like your wheel bearings don’t exist anymore. Had rs-rr and 615k+. 615k+ is better. Both are way off pace but great budget tires. 615k+ is actually a pretty good tire for hpde.

The next set of Federal 595 RS-Pro lasted 30k and looked like OP tires.

Chinese snow tires are hit or miss. I had a set of federals for a short while that handled snow great for what they were.

As others mentioned, run-flats are more suspectable to sidewall damage. They're also heavier and noisier. Also, you may have a wider selection of tires if you go with non-runflat.

I got the wheel and tire warranty when I bought my car. They’ve already replaced 4 run flats for free. I got 2 blowouts in the last 2 weeks hitting pretty average sized potholes that I’ve never had issues before with. Run flats suck.
