XJ number 3, day 7...suggestions?

OK, I'm on my third XJ, a chilli red '99 4.0 Auto 8.25 w/3.55.

Got my C4x4 front hooks from Brown Santa only minutes ago. I'm going to get a rear hitch next, hopefully from the junk yard.

OK, tires. My old '99 Wrangler had 33" Swamper TSLs. My new '99 XJ has 235/75R15 baloney skin radials.

My family needs and wheeling needs require 30-31 inch mud tires. Throwing the kids up into the Wrangler wasn't high on anybody's list.

Would I be silly to get 30x9.5 Dunlop Mud Rovers or BFG MTs and see how they fit and flex? Should I just order T&T boomerangs and some spacers and be done with it? Should I get some retread MTs in 235/75R15 and skip the cheap bb since I know I'll never be satisfied now that I've tasted Swampers and will eventually be back in 33" land?

thanks in advance, rob

Very minor rubbing with no sway bar disco. The MT is supposed to be .5"taller if you believe BFG. I say run the tires and see how they work. If needs be, go up an inch.
