I put the Firestone Transforce ATs (Load Range E) on my 00 Expy EB when I needed new tires a few years ago, with the forethought that I would eventually want to tow a travel trailer with the Expy. It was around that time I puchased and installed a Prodigy P3 brake control (EXCELLENT unit). The tires have way more capacity then my Expy does, but I like a good stiff sidewall tire for trailer towing.
At any rate, I really like the Transforce's. They are NOT noisy on the highway at all, and provide good wet weather traction and the tread is VERY Deep! I expect they will last me a LONG time.
The ride quality is understandably harsh compared to the P series tires the Expy came with, but I really don't care. It's not my everyday driver. To those of you who say the sidewalls ballon, I have not seen that, how much weight are you running when you see that?
The one poster said he was running his at 45PSI? WAY too low in my opinion. These tires have an 80PSI max cold tire pressure, so I run mine at 70PSI. I don't know what your owner's manual or Firestone calls for, tire pressure wise, but I would bet 45 is under-inflated for a Load Range E tire.
I have no experience with the Grabbers.
Good luck!

Mine were at 80psi from the factory, aired them down to 60psi to make the unloaded ride bearable. My Goodyear Wrangler Duratracs didn't balloon out nearly as much as these Transforce Tires. The Duratracs were ran at a lower pressure as well, I ran them at 45 to 50 psi on an F-150. There's roughly 1500 lbs difference between my F-150 and RAM 3500. Even at a full 80psi, the Transforce tires seemed to balloon out far more than the Duratracs ever did. I also don't notice so much ballooning on other tires equipped on other HD trucks. However, I'm thinking that was intentional as the ride is plyant and the truck doesn't wallow or bob around in the turns.
