Morning all,
FK452s aren't going offline in the short term. Yes, the 912 is a new pattern (asymmetrical rather than the directional 452). Asymmetrical tyres do bring a lot of advantages over dirctional tread patterns (quieter, better road holding, improved cornering grip) without losing the strengths a directional tyre brings - water dispersal, straight line traction.
The best place to find Falkens are through a wholesaler called Micheldever and their retail outlet Pro-tyre. The are the sole authorised importer of the Falken brand through Dunlop. Falken has one of the widest product ranges in the market, especially for a non-premium manufacturer, they sell pretty much every size from the good old mini 145R10 through to gangster SUV 22", unfortunately for us Zed owners, we are a very small percentage of their market with the niche tyre sizes that are fitted to our cars so when they're ordering containers of stock from Japan, our needs will only be a very small part of their demand.
I will happily make some inquires as to when stock is next coming into the UK - what area are you in?
