I am purely a happy Lexus driver and not associated with the company below at all. But, I've just had three SP 9000 Lexus 'Made in Japan' delivered for £273. I think this was a good deal so though I should let you all know about it.

They are currently offering good discounts on the pucka SP 9000 Lexus tyre. Doesn't appear to make any sense to go for an inferior tyre when you can get them at this price.
Happy tyre buying!
