road use
hi Nick ,
From reports and also personal experience , the OLYMPIC 900-13's are quite safe for the average MV restorer to use . The only problem with them is , I wouldn't drive around on them on a wet bitumen road at over 40 MPH due to the slick nature of the tread pattern , they tend to slide around a bit .
The latest production batch seem to be all 6 ply , but I have seen 8 ply examples over the years . The new ones I bought are not marked " agrigultural " or speed limited , but reports suggest that some have been marked like this in the past . It depends on the batch I think .
BTW OLYMPIC were still making 900-16 chevron directional WW2 type bar treads until the early 1970's . I wonder if they still have the moulds ?
Mike
