Bridgestone potenza help

I need a bridgestone potenza 215/40r18 urgently. Told they are no longer made by every supplier. Anyone have one spare or know of any in the country?

Thanks
 
Checked all my usual sites - BlackCircles, Tyre Leader, CamSkill, Oponeo, My Tyres .... and couldn't find anything Bridgestone in a 215/40/18 other than some winter tyres.

Is 215/40/18 the standard size for Raiders?

Looks like there's loads available in 225/40/18 though....
 
i switched to continental sport contact 5 on my raider, best move i ever made, the RE050's are **** in the wet
