I wouldn’t be able to remove the speed governor on my truck anyways unless I bought a whole new unlocked PCM that could be flash-tuned with a tuner so my Michelin’s serve me well I spose. Besides, even tho my truck handles 108 mph just fine, and even though I know it’s much more capable of faster but, I wouldn’t wanna go much faster than that anyways. Back in the days of not having to worry about buying unlocked computers, the fastest I had my old 08 up to was about a 120 and that was a bit much for me. As I said, my new truck handles the higher speeds much better than my old truck but even 108 feels to me like right on the edge of being too much. lol.
But yeah, I was just wondering what pressures you run to maintain full tread patch contact even though the 305’s are only a little over an inch wider.
The only reason I was asking was because on my old 98 ram I once had, I was running a 285/75/16 on the stock 16 x 7 wheels when the factory tires for that truck was only a 245/75/16. Those were only just a little over an inch and a half wider than the OEM tire size but it was enough that I had to run a lot less tire pressure in my back tires in order to get the tread patch to make full contact with the road because it pulled in the side walls so much.

Moes is actually running a PCM swap/tuner deal right now that makes tuning ours a little easier. You can grab a hemifever engine/transmission tune from him in the deal as well. Much more economical than buying an unlocked PCM, or shipping yours off to get unlocked. You just have to send yours back to him once you get the unlocked one. Im looking at going that route pretty soon.
Back on the topic of tires, i wouldnt know the necessary pressure for the wider tires yet, i still have the factory goodyear wranglers on my truck, since theyve only got 5600 miles on them.
