I have always found Michelin tires to give the best ride. They have some styles that the sidewalls are so soft that they look underinflated , when they aren't. I wouldn't recommend them for offroading or on a construction site where you could pick up a lot of nails. If those things don't concern you you might go into a tire store that sells many brands and squeeze some sidewalls, find a cushy one,with tread design you like, in the price / warrantee range to fit your budget. Also running the widest recommended tire for your rim can provide more cushion. I have wished for cushy tires before , when I slipped a disc in my back and this is how I would choose. Just my$.02, bob Ps., you'll want some good shocks too. Maybe someone can recommend them.
