Best Tires for 2014 X5 35d

[BostonBC]

My original X5 35d tires have 47,500 miles on them and I am thinking of getting new tires. I live in Boston so want something good in snow/ice as well as regular driving tires for good peformance and quiet ride. Mostly drive around city and highways - no off roading.

I plan to have the car for another 3-5 years (40-50k miles) and want to only buy tires once. Current size is 255/50r19 Goodyear RunFlats.

Thanks for any insights.

I'm pretty happy with the factory scorpions we got on our '17 35d. I haven't had them in snow yet, so I'm looking forward to see how they do. If your factory tires got you 47K miles and your happy, maybe that's your answer.
