I have a set of 5 Yokohama Geolandar X-AT tires from my old LR4 that I no longer need. They are LT295/70R17 tires which works out to about 33.5". They have 8mm of tread depth left.
I also have a set of 5 BFG KM3 tires in size 35x12.5x18 that I briefly had on my G-Wagen before I upsized to 38" tires. 1 is unused with 14mm tread depth, the other 4 have under 1000 miles on them and 12mm tread depth. They are mounted on Mercedes wheels which I don't need but if it's easier for you I could have them unmounted.
