Attention: TDR Forum Junkies 
I have the Rickson steel 19. 5" x 7. 5" wheels and 265/70R19. 5 G Hankook DH01's. This combination of wheels and tires is HEAVY. I think they approximate the weight of the oem duals. BUT, they are also very strong (the wheels are rated at 5,000 lbs each and the tires at 5070 lbs each at 110 psi. They can safely handle far more weight than the oem SRW tires and wheels on the rear of a long bed pickup. They aren't quite up to the capacity of the dual rear wheel setup on the rears, but redeem themselves by being far more capable than the oems on the front axle. (I've heard that oem dually wheels singled out for use on the steer axle are only good for about 2800 pounds per wheel. ) They also maintain the size envelope of an SRW truck, which is nice in drive-throughs and parking lots. They are also far superior to a dually setup in snow or off road.
These heavy tires/wheels require much better shocks than the oem units. I have Bilsteins and they work very well. This setup yields a stiffer, more truck-like ride than the oem setup by far, but is far more capable of handling heavy weights and road hazards than the LT oem tires will ever be. These tires are 34. 5 inches tall and also work well off road, although they are by no means a sand tire. They offer no clearance issues on the steer axle, although they probably would if one attempted to chain-up the front axle. These tires work quite well in snow all by themselves. I have mine siped and spin balanced and then use Balance Master Centrifugal balancers on the front and Centramatics on the rear. (The Centramatics I tried to install on the front wouldn't fit properly, but the Balance Master unit intended as a dual wheel balancer worked wonderfully on the steer axle. No balance problems whatever in 30,000 miles. Concurrently with the install of these tires and wheels I also added dual steering stabilizer shocks to the oem unit so have a triple stabilized steer axle setup. I have no hint of shimmy or death wobble with this setup, even running the tall and heavy tires/wheels.
My setup handles a 40' 3 axle toyhauler with ease. Grossing between 23K and 26K depending on the water load and particular toys being hauled, these tires and wheels have proven to be essentially bulletproof. My pin wt is near 4500 lbs, which is also the capacity limit of Reese 18K hitch. This puts the rear axle wt at nearly 8,000 lbs, which is well below the axle, wheel and tire limits. Firestone Ride Rites at 70 - 75 psi make the truck sit level at this load and coupled with the Bisteins deliver a nice ride when loaded.
If I had it to do over, I'd do this wheel and tire setup again, which is a pretty good statement of the way I feel about them.
