Tested all the tires in the FAQ and ended up with PMT e-fire (https://www.pmt-tyres.it/en/shop/e-fire-10-x-2125/).
- they're made from real rubber, not nylon
- operational pressure is much lower (2 BAR), so their contact with pavement is the same like 10x3. this combined with softer rubber causes that they're much more comfortable and dampen much better.
- stability is also great even in 60km / h
- mileage is slightly better than 10x3
- traction is greatly improved, even on wet surfaces
- only disadvantage is possibility of speed wobble, because of softer dampening, but can be mitigated by pressurizing to 2.5 BAR or slightly higher.
