I'm selling a couple of rear Toyos as well, but I've also got another full set mounted with TMPS on some bmw performance wheels. I only put about 35 miles on them, took them off for some winter tires, but now have to sell as I'm moving and can't take with.
I paid about $2400 for everything and is still all like new, BUT I curbed both the front wheels. Not super horribly and only noticable up close, but thus the huge discount. I can send photos to interested parties but I need to sell these within the next 5 days so if you're interested, please make an offer.
