Long-Term Updates - May 2013

Pro Comp Xtreme A/Ts
Admittedly, our tire testing in snowy terrains is minimal. We don't usually get to enjoy the white fluffy stuff as often as we should, but this year we changed that by sending part of the staff to brave the northwest for the winter. Along went our 2011 Super Duty on 37-inch Pro Comp Xtreme A/Ts. While we have no doubt that the 8,500-plus-pound weight of the truck helped, it was almost unbelievable how well our newer Xtreme A/Ts worked on ice and on snow-covered roads. The traction left us sure-footed and cruising along without chains for the entire trip. In fact, we've been pleased with every off-road circumstance of this tire leaving the pavement. Now for the bad: While this tire handles all terrains exceedingly well (including highways), we did see a noticeable dip of about 1 mpg when switching to these tires from a different 37-inch-tall tire. We attribute this to the fact that this is actually a taller 37 (generally speaking), and the fact that there is more tread depth and larger tread voids. But these are the same reasons that this tire excels in the dirt.

Power Tank Digital Inflator
We're guessing that you're familiar with Power Tank's CO2 tanks used for powering air tools and filling tires off road. But you may not be familiar with all the neat air accessories the company has available. We just ran into someone on the trail with a new digital inflator. We're told pressure readings are accurate to 0.01 of a pound, and it works to tell tire pressure regardless of if it's hooked up to an air source or not.

PSC Steering Kit
For years, we cobbled together steering kits using parts from multiple companies on our K5 Blazer. And the steering has never worked like we wanted. It has always been too slow, we could never get the belt not to squeal no matter how tight we made it, it didn't have the power it should, and we finally came to the conclusion that our collection of oddly matched parts needed to go. We replaced the entire system with a complete PSC hydraulic-assist kit after years of problems. We have not had a problem since. No leaks, no squeaks, and we haven't had to make any tweaks.

While it's generally known that a hydraulic-assist ram will slow down how fast you can steer, we saw no drawbacks with our complete PSC system (where we clearly had that problem before).
