I am interested in trying out my new tires they measure a little over 29" (even though the size is 30x9.50) now that I look back I should have kept the buckshots I had, those were 30x9.50 as well but the measured 31" so that would have given me an extra inch of lift. and where the lift counts is the tires, you can have a 10" lift but if your tires are 30" tall, you will only have so much room between the rear axle and the ground, only way to move that up higher is with taller tires.

BUT then you DO need the suspension and or body lift to make those bigger tires fit. Thats why I say the sky is the limit (well your wallet is your own personal limit!!)
