Getting ready for our yearly fishing trip and trying to decide if I need to spring for a new 35 for my spare. Really dont want to spend the 200$ for a spare, but messing up my drive train fer sure isnt a option. So any helpful input would be nice. Thanks..

I've heard different things from different people on this subject. I used to have an XJ w/33" and used the stock 28" spare a couple times. I always used the spare in the rear (because your steering goes wacko w/two different sized tires on the front). And NEVER use the locker - you'll either get non-stop tire chirp or worse mangle your rear dif. I don't know what the FT 4WD will do w/a different tire, but I can't imagine in an emergency situation it would kill you.

Why not also carry around a simple tire fix kit. They are $5 at wallyworld and if you have an air compressor you can fix most flats on the trail in no time at all.
