Need some 29 inch tires.  What's the longest lasting tires you guys have seen on a tracker?  Toyo MT last long on my dodge, but does not come in the tracker size

The longest lasting tires are of harder rubber, and therefore do not grip as well as softer tires.  The more aggressive tires will not last as long as All Terrain tires, and really aggressive tires do get noisy.  Getting tires for what you really use them for will get you the most out of them.
We had a set of Kumho tires on our Desert racer (that were used when we put them on) that held up good enough that we passed them on for further use.  I also had a set of them on my Tracker in 30x9.50x15 for years before up grading to 33's.
With the lower weight of Suzuki's most of the Truck tires are going to wear longer than average (with good alignment).   
Craigslist has produced some very good tires for the price for me.  My last set, 5 Toyo MT's like new (one was) for $650 and new would have been over $300 each.

And there lies my problem; I have a 99 4 door auto 2 inch BL and 2 inch coil spacers.  I wanted 235 75 15s or 29x9.5,  no trimming and decent power, but after having 33x12.5 on my 93 2 door 5 speed I really want the big tire. Big tire, more area so it has to last longer. The only thing holding me back is fuel economy. Gas is stupid expensive and the company is struggling.   Maybe 31x10.5?  I don't know about the rear door fitting either.  No re gear anytime in near future so i would have to live with the stock gears.

31" tires or larger will be a huge reduction in your engines ability to turn them.  MTs are heavier and not just larger diameter and they can be even more difficult to spin because they bite into the terrain really aggressively.  Unless you re-gear your diffs, you may not be happy with 31" or larger tires.  Larger tires are of little use if you don't have the power to turn them.

Toyo Open Country MTs wear very well, bite very well and they are incredibly quiet on the hard ball given their aggressive tread design.

Kelly Safari TSRs are decent tires and although not a pure mud terrain, the Cooper Discoverer S/T are pretty damned good multi-purpose tire as well.  I've been running the S/T for about two years now.  They have been good on dry roads, snow, and regular old dirt and mud.   The Cooper tires generally have a deeper tread lug than standard passenger tires so you can put some miles on them and still have more tread left on them than another branded tire comes with new.

Go to a 16 tire  and get some 245 75 16 Cooper tall and skinny, get a set of Grand Vitara wheels and there a 30" tire

Picked up 31x12.50 swamper boggers for $500 on Craigslist. 

33/9.5 .....tall and skinny. I have a set of federal contouer mt i  30/9.5/15and love the tire would buy them again great mud tire

Tall and skinny tires are good.  You can still air them down when needed, just like any other tires.  Hooking up requires traction and traction requires tread and ground pressure. 

Long ago I drove the M151A1/A2 series "jeeps" that the US military used predominantly.  They had biased ply 16" tires on them that had 7 inch wide tread.  I drove those trucks into streams, up streams, over logs in the streams, out of streams, up steep river banks, in various types of mud, in packed sand, in deep sand and also occasionally cruised on the highway at 65MPH (which violated the 55MPH speed limit).  Those little trucks would go where you pointed them, but... driver's skill was still required to keep from "sticking" them.  I still preferred the M151s mobility to the HMMWVs  when it came to cross-country mobility.  Probably for the very same reasons I like these Suzuki vehicles today.

There will always be places and terrain where four wheeled vehicles won't go and where inexperienced drivers will get them stuck.  The head-space between the ears is an indispensable asset and every bit as important as the vehicle's capability.

I've been pretty happy with my Kumho Road Venture KL71 MT tires. I've probably got 15,000-20,00 miles on them. Still going strong.
