Tires OEM BMW or LANDSAIL

i’ve got a 2.5 gen so i can’t say much on sizing, but check out land sail. i got ls588 UHPs on mine and ive never had a quieter, smoother ride with insane grip for sub $100 a tire.

i have landsail ls588 Ultra High Performance tires on mine 245/40 R18s. good price and very quiet while having insane grip

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.

but given they're landsails anyway i'd definitely replace them with something (better preferably) just for piece of mind

Landsail tires at 150mph. Yeah would not recommend...

Landsail tires should not be trusted at all, and Darwin will be having a meeting with you at that speed.

The run flat tires are terrible. They feel like they are made of concrete and the grip is very lacking.

I got my car from a dealership with Landsail tires on it. Complete garbage
