You could test it on some black ice.
Ive been thinking about wear rate and how easy it would be to replace all the screws. I dont think it is a major job, about 2 hrs.
Each screw head is backed by a cut out square of inner tube and these would have to be removed and reglued (using Copydex rubber adhesive). I tried gluing a whole inner tube in place but it is easier with smaller bits.
