I recently bought my 95 Tahoe 4x4 stock height . I bought some 285/75/16 kumho road ventures pl78 brand new maybe 100 miles guy wants to trade me his Goodyear wrangler authorities 265/70/17 on soft 8s C rated tire with about 5000 miles and a fifth brand new tire. Fifth tire does not have rim just a brand new tire unmounted. Should I do the trade? Or better question would you do the trade if you were me?
