The tires are 285s and are on AOR steel spacers at the moment. If you guys remember AOR, they were the only company I had found to machine steel spacers. Without the spacers on stock 16x7 rim, it rarely rubbed. With the spacers, the rubbing is bad but tolerable. I really do need a re-gear; my acceleration suffered quite a bit with the extra weight and larger tires, that is somewhat offset by the supercharger and the 7th injector, but of course gas mileage suffers if I want to go anywhere fast or up a hill. In the city, I'm down to 12 miles per gallon easily if I try to drive it like it was stock. Up large hills, I use a lot of boost and mainly drive with overdrive off / ETC power on.
On the other side, having the torque from the supercharger and higher gearing gives me fantastic gas mileage on relatively flat roads. Not a very strong analogy, but its like a v8 idling at 2500 RPMs at 80 mph. I get 18-19 mpg on flat highways. A re-gear is definitely in the plans.
Phatman, the tonneau does not keep rain or snow out indefinitely. Each post that the rack is connected to required a square flap to be cut out. In addition, when I installed the gas lift springs there was two additional 1 foot slits I had to cut. While it does a good job of keeping the water out, a small amount of water does get in. Without holes cut into the tonneau, it keeps rain out well though dust always gets in somehow. I only keep items which have a bag or box inside the truck bed because of the water and dust permeability. I was thinking of velcro sewed at all the flaps and slits, but again that will only reduce the amount of water into the bed. It doesn't concern me too much since it doesn't rain much down here.
It would be neat to see someone using a hard tonneau to mount their tent on top of that, though I'm not sure I trust the fiber glass ones alone to support the weight of the tent. It would be much easier then to un-snap a fabric tonneau.
