Time to install tires on my truck camper setup

So far I like the Falken at3/w's they are snow peak 'certified'

I went with 37's but I also did not lift it either to maintain factory geometry. The tires are rated for 4000 lbs at 65 psi.

With the right wheels, you don't need a lift for 35" tires, proof since I am running 37's.
