Tires OEM BMW or Hifly

I have old michelin 185hr15 on mine, but for 14 inch the closest That was cheap and available was HiFly 195/70r14 for $90 a piece

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.

Awesome bike, but swap out the stock tires asap.

Swapped my wifes Z4 from runflats to normal.

Pros: better ride, less likely to crack rims, cheaper tyres.

Cons: no spare tyre.

Before I switched I had 4 sidewall tears, one bent wheel, and one cracked wheel. $3000 in damage. After I switched, zero issues a year and a half later. Smoother ride and less road noise too.

I have hiflys they’re fine

Hiflys will be fine

I sell a fair bit of them, only complaint I get from customers is they get a little noisey toward the end of their life. But they do their job and do them well enough

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.

It was a commonly traversed dirt road, a little soggy after a rain storm and I backed my dad\u2019s brand new 2008 335i into a small mud depression with the right rear only. Result? Absolutely dead immobile
