I live in the end of Hartford with giant grinders. I try to follow suit by putting giant tires on my bike. A little more than a year ago I bought this lot of a couple dozen (or maybe more) tires. There were a lot of downhill tires, which aren't much use to me because the front fork of my Stumpjumper is the only place with clearance for them. None the less, I really enjoy putting a giant tire on there. For awhile, I had a super tacky 2.5" Maxxis High Roller. It was pretty good, but I knew I could do better. A couple months ago while wasting time on eBay, I spotted 2.8" Bontrager Big Earls at a good price. So, I bought them. I finally took it out yesterday and it's quite the experience. And, it has surprisingly low rolling resistance. However, I think I've met my match in terms of tire width with rim brakes (or at least V-brakes), because under heavy braking, the left arm hits the outside knobbies.
