Yes, I thought so. Another aspect of tire fit and these non hook edge rims is the usual lowering of the tire's max pressure rating. Without the rim's hook to help mechanically fit the tire's bead the bead can far more easily creep up on the rim's sides and blow off. I usually decrease max pressure by 10 to 20% with these rims.

That's a sweet Gitane.

Glad you fixed it!

Just one more data point / anecdote: I had a Continental Gatorskin that showed exactly what you've got in your video. I could not get that to be any better after deflating / reseating / inflating repeatedly. The bead and tube were seated just fine in the wheel, so I finally accepted it must be a messed up tyre, and I bit the bullet and just bought another one, which worked perfectly. Sometimes you can just have bad luck and get a bad tyre.

Thanks, I really like it! I just started riding again a couple of months ago. I had been a runner but have been sitting around getting fat. I thought it would be a good idea to go for a run, but my knees didn't think a 215 lb. guy running was so smart after all. So I started keeping an eye out for a bike. I got this at a yard sale. I put a chain on it, shifter cables, bar wrap, cleaned and adjusted everything. Oh, and the new tires and tubes. That really seems like all it needed. I'm going to go though the hubs just to be sure it's all good. It is an old bike, and I don't think much maintenance was done. The chain I took off was really stretched. I really don't know if there's damage to the cogs. But it's riding really well now. I just got back from a 22 mile ride up over a reservoir, around the lake, and up the other side. It rode great, and it's SO nice to have that hump out of the tire.

But I digress. Thanks again to everyone who helped me get this sorted out!
