To replace existing silent tread. Experimental Test Report. We have run this type of tread on 19-G-IV. and at present have a set running on 25-EX. Sales have done a considerable mileage on the 40/50. Road Test Report. These are a compromise between the triple stud and silent tread. They are definitely more noisy than the existing silent tread, as one would expect, but a better non-skid.
