HELP ASAP....Screw in tire....get 4 new Hankook V12's or 1?
 

took the G to the dealer to get a screw removed from the middle of the tread and have it patched. called back and said it had 2 screws in it....1 in the middle of the tread and 1 near the side wall....obviously the 1 near the side wall cant be patched, so im going to need a new tire. he said my tires had 7/32's of tread left, so i could get away with buying just 1 tire. i was planning on getting new Hankook Ventus V12 evo K110 rubber all around when i needed to, but obviously this throws a wrench into those plans.

big question is, should i just buy 1 Hankook V12 from tirerack to replace the screw riddled tire, buy 2 Hankook V12's for the rears to keep things even, or just get all 4 right now since they have the $50 rebate until the end of May and just hold on to the front 2 until i need them?

dealer charges $286/stock Conti tire....4 Hankook V12's on tirerack shipped are $690 (-$50 rebate brings them down to $640) and the delivery estimate from tirerack is 5/14-5/15 (friday or saturday)
