Tires MICHELIN or OEM BMW

Defender 2 is excellent and reasonably priced

I use Michelin 235 40 18 4S on my MK7 with Neuspeed RSe12 8"x18" and the grip is a tick better than the standard size. This combo is also lighter than the stock wheels and tires...and along with the suspension modifications, it's a difficult subject to try to quantify. I am always concerned with wheel and tire weight...that drives my decision making...if you like the look of a 19" rim, go for it. I think that you will find a larger variable between tire types and widths where ultimate grip is concerned...steering response is in theory better with a lower profile tire, but sidewall construction will also affect steering response with a similar tire size range.

I just put the Pilot Sport 4S tires on my 21 3.3 Sport Prestige and I absolutely love them. I had kuhmos on it before and they were absolutely trash tires compared to these. These new ones are way stiffer and way better performance in turns and just all around feel like a better tire.

Michelin Cross Climate 2's unless off roading.

I like my Michelin Pilot Sport All Seasons. Grippy, great wet performance, and it won't break the bank.

Michelins for the best wear. Not nearly as soft as khumos though so won't grip quit as well. I got 75k out of my last set

New X-Ice are great in snow and ice. They wear quite quickly in warm weather.

Have to say I have been impressed with them so far in all conditions. I had assumed they would be noisy, but no more so than a more conservatively treaded tire.

Another vote for Michelin Pilot A/S 4. I had them on my 2016 Mazda6. They were quiet and decently grippy for a non-sport all season tire. I hate them. They’re not as noisy as the OE Dunlops on the 2016 but when cornering they’re like driving on mush.

The best I've had are the Dunlop Direzza Star Specs (I and II) for summer. For winter ofcourse the Bridgestone Blizzak WS90s for the Michigan winters. I've had a set of Kumho Ecsta MX's and they weren't bad either, but the worst by far were the MICHELIN PRIMACY all-seasons. Noisy, tread lasted less than 20k miles and obviously it's unsafe to wait until 2/32" so not even replaceable under warranty (which claims 80k miles treadwear ....pfft). Never again.
