Tires OEM BMW or Cooper

Out of these options.

Cooper 10/10

Personally, I like Uniroyals but Cooper is good too.

Coopers are WAY better tires than the Uniroyal or Westlake...

Awesome bike, but swap out the stock tires asap.

The Cooper Zeon are significantly better, especially in the rain. I don't generally *try* to roast my tires, but there's been many situations where these Zeon tires have held grip where the Extensa would undoubtedly let loose.

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 ride the tires at 42 psi and currently w/ new Cooper Instincts at 44 psi returning comparable mileage.

I have a set of Cooper 225/60/18 snow tires that grip really well, but I don't like the way they drive. The skinniness makes turning feel loose, and it feels like the car is going to flip (though it definitely isn't).

Mine were horrible in the rain. I swapped them out for Cooper AT3s.
