Cheapist place to buy Yokohama AVS ST 285/60/18?

Thaks to eveyones advice, pics an input I have decided on Yok AVS ST's in 285/60/18's and need to have some input on best buy on these tires? Thanks...Now must decide how to solve this rim issue. Really want to rid myself of these chrome 18's and will never find the Borbet CW3's I seek.. If anyone interested in full set with stock tires in excellent shape LMK..These are a new set I recently got from dealer to replace originals that were bad at delivery.

I would recommend discount tire. One benefit I learned recently was the fact they pro rate for a replacement tire if you run over a bolt. I did not buy road hazard so my replacement NITTO was 70 instead of 170... Had I paid for road hazard it would have been free. I also get free balance for life of tires.
