Excellent, Chris! My 58mm G-One Speeds had some self-steer, where they’d try to climb the crown of the road, or suddenly get grabbed by a crack in the asphalt. The BQs you’re getting explain the physics of the runner, I think. I only noticed it on a low-trail bike, and not all the time; high trail bikes didn’t do that. It makes sense that low tire pressure causes or contributes.
I switched to RH 55mm knobbies, and haven’t noticed it again. I think the less rubber area keeps the tire from steering the bike. On dirt, I never noticed any of the self steer.
