I've already seen your post, but the big problem is that I live in Europe, and there is less shops that sell that type of tires...
I only know
Cheap Tyres Discount Tyres Buy Tyres Online & Japanese Import Car Parts Spares Tuning Performance Servicing Accessories , nearest and cheapest shop I know in Europe... But they don't have the size I want. :/
I'll try to find a UK Forum, but I'll stay here, there are so many informations on this forum! I will need weeks to read everything.
