I got a set of 245 75 17 tires for free. They are pretty much new my friend only put about 4000 miles on them before getting some off road tires. What will I need to do to use them on my TB? Will I need both wheel spacers and a lift kit or can I just get away with wheel spa ers? Also what size spacers will I need? And if I'm going to need a lift as well what size do I get? Thanks
