At my heaviest, 305 I was riding on Schwalbe Durano plus 25's. Max rec pressure was 115. I ran them at 125 on some bad roads and they were fine. I can not recommend these tires highly enough. Yes they are heavier but they are outstanding for durability. I don't necessarily agree that you have to give up a pure road bike cause your over 200 lbs. I don't weigh 300 anymore but I always enjoyed this style of bike over any other kind out there.
