gmw, am I reading that right? You put more air in the front than the rear when towing? I guess I had it backwards!
And you are right that I am not coming anywhere near the load limit on those tires, so I guess I can back down from my high pressure settings. I don't want to run the tires so low, however, that the sidewall flexes and heats up the tire during normal highway driving.
And on the third hand, more psi equates to better mileage, but too much psi will cause wear on the centers of the tread.
Yes, Dan you read that right. I hesitated to use the dually as an example, because the fact there are four tires in the rear makes it an apples to oranges comparison, and can sometimes just confuse the discussion. But that's the way it works....with four in the back to carry the load, and only two in the front, the pressures need to be lower back, higher front.
In your case, the added puncture resistance you will get with your new tires compared to your old ones is going to come from the much more robust construction. Compare the weight of your new tires to what your old tires were ( the weight will be on the BFG site or the tirerack site ). You'll see a major difference.
Also, go back to my previous post re my Frontier with the FF hooked up, and you'll see that it weighs nearly the same front and rear when I am set up to go camp. As a consequence, I run the same pressure F/R on that little truck, since the loads are essentially the same. I experimented with higher pressure in the rear tires of the Frontier, but all it did was wear the center more, so it was clearly too much.
Here's a suggestion: since your new tires are heavier, that means more unsprung weight. This may cause you to notice any deficiencies in the shocks, especially at speeds over about 40 mph. If you have not already done so, I would recco Bilstein 5100's for it. They are about the stiffest damped shock you can get for it.
