Tires OEM BMW or Continental

typical time on GP5K 28mm is 45mins with a dead shortest time of 32mins with a strong tailwind. Both bikes set up to have nearly identical geo relationship between saddle, primary grip area, and bottom bracket and thus identical posture.

I notice it everywhere in my riding- turns, takeoffs, climbs, I *definitely notice it* on multi hour rides… and I’m no pro.

I went from Kenda to Conti GP 5000s and it felt like I got a new bike. And my speed increased by several mph. You just can't get upgrades like that with any other component

When I switched to Conti GP4000sii, those were 12.2 watts per tire. Total of 24.4 watts.

The difference between them obviously 40 watts (depending on conditions). Yeah, that is a big deal. And you can feel it. One is like pedaling through mud in comparison to the other floating over the road.

DWS06 on all my cars. By far the longest lasting and best performing tire and cheaper than the competition.

My brother has dsw06s on his Focus RS. They're awesome tires but have a short lifespan. I got Conti PureContacts and haven't had a single complaint, they've never lost traction or hydroplaned (not for lack of trying), and are quiet except on perfectly smooth pavement.

I like my DWS06+ set. Not terrible in snow and pretty good in rain.

DWS06+ user here. Amazing tires, especially in the rain.

The stock kinergys are quite bad new and once they start approaching 1/2 life left, became honestly dangerous in the rain from my experience. I replaced them with Continental Extreme Contact DWS06+’s well before the tires were worn out and haven’t looked back. 100% worth it.

Now my experience with the ECS02s vs my typical 200tw Yoko AD09s is they do not have the same ability to grip and I have to brake earlier and carry less speed into the apexes or they slip/push a bit.

just FYI I tried the Conti DWS on my 2009 335i and couldn't keep them on the car. every time I hit a pothole the sidewall would crack and the worst part was despite the fact that I knew how it happened every time each road hazard claim was denied due to "improper installation".
