but i’m not totally sure what kind of bike we can mount on those tires, …why no 21 inch front ? Would be a total blast hooking up that 18 inch rear on some massive displacement mx 
I think i’ll pass on these for my Trials bike, too much danger of drowning while riding.
…edit that, your link has a 21 inch trelleborg available so I can fit these things. Now where would one go to ride with them on?
