Yeah best bet is to go with the lower sidewall size and go with the Hankooks. Sure it's not 100% OEM fitment, but it's better than paying $2000+ for a new set of tires.
We're a Hankook dealer, we've got the Hankook ventus V12 Evo 2 tires in 245/35/21 and 275/30/21 for $864.06 + Shipping, $50 less than Tire Rack has them so if you want a set, let me know
