That's a good tire, you can start with 235s with
no lift, or 30s with a suspension lift and trimming
A less expensive way to lift the suspension would
be to get a set of coil spacers from Digger, front and
rear, a set of Ford Crown Victoria shocks (rear 98) for
the rear of your Tracker, and a pair of front extensions
that I'm working on right now, available in about 7-10
days, I can't remember what Digger gets for the spacers,
lets call it at $50, I think $50 for the Extensions and $40
for the shocks, so for about $150 you get a 2" suspension
lift, add tires and enjoy
As time and money permit add a rear locker and a body lift,
I would enjoy the trracker for a while, and as the tires wear
out, plan your body lift and replace the tires with 31s or 32s
along with the wheels with some more backspace, I would use
7" RockCrawlers, cool design, not too expensive (around $50ea)
and a backspace of 3" should work well with a 31 or 32 inch tire
