Do a mild pre-runner setup. Do a 3" spindle drop and a 1 or 2" body lift, and you can get some 30" tires under there easy with plenty of clearance.
A 3" body lift will clear you 235/75-15's.
Look into a upper A arm drop, crank the t-bars, and a add a leaf. Won't break the bank and you can take it all out if you don't like it! And still get really good mileage out of it.
