My previous career was 17 years in the tire industry. I thought I might throw a few things in for you to consider
1. Buy the best tire you can afford. Premium tires are always less expensive in the long run.
2. Consider the service after the fact. I think this is very important. Where will you get a flat fixed? What if I put a stick through the side of the tire? Buying online can save you alot of money and i probably will when i buy tires for the FJ. But then i can fix my own flats. The 2 places in the PNW that have the best service after the fact are Discount Tire and Les Schwab.
3. You wont go wrong with the BFG. That tire has been proven over and over again
4. You cant go wrong with the Aftermarket Toyo or Nitto. Toyo and Nitto are like GMC and Chevrolet. the same on the inside and look different on the outside. Most Toyo's and Nitto's are made in the same factory with the same casing. The Mold for the tires are different. Toyo like all manufacturers will make tires for Original Equiptment cars and trucks to the car makers specification. They had a bunch of O.E. tires on some toyotas that were wearing out extremely fast. More than likely because of a specification from toyota.
6. You wont go wrong with Michelin All Terrains. They do not look the most off road out of the bunch but is a very good tire. That is what I currently have on the FJ because they came with it.
5. General's, Cooper's, Falken's are all good upper middle quality tires.
6. Almost always Ride Quality, life of the tire, etc will go down as the price goes down, but be wary of a tire that carries a premium price but does not look premium. Also be wary of a premium name brand tire that is considerately less at one place than it is at another. Some places will order tires that have less tread so that they can compete on price alone. for example tire store A has a tire for $212 and Tire store B has the same tire for $182. Tire store A's tire has 21/32 of tread and tire store B's has 10/32 of tread.
7. Take into consideration how the tires will look. I have put tires on vehicles that were too big, heavy etc simply because they looked good. And i wanted that look more than i wanted gas mileage, low noise, driveability etc. That being said I am considering the Milestar Patagonia for the FJ, A tire i have only seen youtube, just because it looks good.
