I’ve found fat tires in general can feel very different depending on pressure. It can take some trial and error to get it right. Usually for me there isn’t a pressure that is good for both trails and roads. I tend to run it kinda low – more like 1 bar – for extra grip, but that makes it handle like a tank on the road. At lower pressures, those wide tires can swallow bumps. You barely notice them.
2 bar is pretty high for muni and extremely high for a plus size tire. If you look at some of the older tire threads, you’ll find people trying ridiculously low pressures – almost flat – in order to roll over big bumps that they can’t get over otherwise. So try a wide range and take your time figuring out what you like.
