I am cuurently building on a second hand mountainboard i bought and the tyres are somewhat wore off. So i am thingking on replacing them But i have found Out they have horrible traction, especially the ones with motors. I mainly do offroading and the tyres are better at digging than pushing. I found this tyres
wich look like they have nice offroad traction so i was wondering ir anyone has tried them or can recomendad something else with nice traction Thank you very much
I’ve got similar tread tires - primo strikers… they also have ‘‘flat’’ middle section and some ‘‘grooves/ teeth’’ at the sides… they work okay on hard packed roads… but they struggled on the snow (single drive)…
I assume for pure off-road, perhaps, ‘‘knobby’’ tires would be the ones to go after… though let’s wait for someone else to step in… just thought to help out with pushing your thread in the front 
Thanks for the info. And the push. Were could you get those kind of tyres shipped to Spain ?
Check uk mountainboard sites. Trampa and atbshop should be your options
