Dudes... I just came across a smokin deal on some Nokian Vativa tires. They are brand spanking new. Guy just put them on his truck and then blew the engine. Last I priced these tires at this size I think it was going to run me about 800 bucks.... guy said he would sale them to me for 350 bucks... they are 265/75/16... so i would need to get a set of 16 inch rims..thats about a 31.5x10.5 tire. what offset would i need?
