I have a 02 jeep wrangler. I have 31" tires right now. They are almost shot. I want new tires and were going to do 33" bf goodrich all terrain. Are these true 33"s i have a 2" coil spacer lift with rubican coils which supposidly give you an extra inch. Will the all terrian tread fit? I hear 33" all terrain are really 32.5 and small enough to fit.
