I’m planning to try 650b+ or almost + and this is what seems to be more or less available here in Poland. Do you have any experience with any of these tires?
Schwalbe Nobby Nic and Rocket Ron
Both available in 650bx2.8 and 3.0, but I was never tempted to use them in smaller sizes as there was always something better around. But I see some good comments here on NN, so maybe it is worth a shot.
WTB Trail Blazer x2.8, this one is tempting and for sure I can get it in a few shops here
WTB Trail Boss and Bridger, both in x3.0, but with only hint of availability
Panaracer Fat Nimble x3.5, available but said to be much smaller - more around x3 or even less
Maxiss Chronicle x3.0, available, but seems to slick for me
