I have a 99 chevy 2 door tahoe and iv planning on getting a 4 inch body lift or so. right now i have really expensive tires but they are not big enough. i have goodyear wrangler 275/70R/17 i think there like 31 inch tires. I have heard good things about BFG off road tires but which one and how many inches are good? My vehicle is used for street to so id want a tire thats big enough to match my lift, good at off roading as well as driveable on the street. im looking to spend about 160-170 on each tire. thanks.
