Thanks for the replies I had ordered a Mitas H01 from a local dealer a couple of weeks before christmas including fitment but after quite a few phone calls from me I was assured it was delayed by the christmas rush ,so in the new year I phoned again to be told it was on its way ,and then on Friday this week after another phone call from me I was told there was an account problem so it would not be delivered, I finished up going to another large tyre company and fitted an Avon tyre ,I must also say the tyre fitter was superb it took approx 30 minutes to remove the very old existing Firestone tyre as the side was were very stiff with age ,he then cleaned everything and refitted the new tyre ,all up more than an hour in total,from what I have found out Firestone were sold to Bridgestone in 1988 the tyre said heavy duty gum dipped but had no date code on it, my bike prior to me buying it had been off the road for 25 years
