I wanted an Avon AV55 Storm Ultra to replace the Battlax that was getting a bit bald on the rear, as I had got an Ultra on the front and found it to be pretty good.
However when I tried to get one from my usual supplier (mytyres.co.uk) they only listed the AV56 and AV57. Looking through the listing supplied I noticed that there was a Nangkang priced at £70.50, which I thought was a bit too cheap. I've had Nangkang tyres on various cars and always found them to be very good, both in terms of grip (dry & wet) and longevity. (And, of course, price)
So I decided to give it a try. It's described as a dual compound rubber, hard in the middle and softer on the edges, along with some technical jargon which I assume to mean it's built terribly well and will be almost indestructible!
Some tyres, when first fitted, feel a bit skittish on corners as the silicon mould release, used in manufacture, takes a while to rub off. But this tyre felt superbly sticky from the first ride, which was a good thing seeing as I overcooked a tight bend coming home from work, going a bit faster than I should have been, and having to crank the bike right over to get myself out of trouble!
Quite how long it's going to last is another story, just as long as it's more than the 4000 miles the Battlax lasted.
If you fit your own tyres, like I do, with tyre levers, washing-up liquid, blood and exotic swear words, you shouldn't find it too much trouble as the tyre is extremely well made and very flexible.
