Anyone running bfg radial t/a’s on the front? How do they ride?

The best tire pressures are the ones that make the tires wear out evenly all across the face. If the rim size is a little too wide for the tires, it requires extra pressure to push the center ribs down onto the road. And if the rims are a little too narrow (as in my case), it requires LESS pressure, so the center ribs can pop up a little. The goal with expensive tires, is to get the maximum mileage out of them.
The starting place is usually to have a rim width that is the same measurement as the tread width. The trouble is that modern p-car radials are not measured by the trad with, but by the carcass width. And for long distance orders like yours, ordering the right tires for your wheels is a bit of a guessing game. And so that leads to tire-pressure experimentation.
It usually takes in the neighborhood of 3000miles for a pattern to show up on the treads, and then you make an adjustment.If you have a serious problem, you might havev to drop the pressure 5 psi to resolve it. A minor issue perhaps 2psi.
Pressures are always adjusted cold, that is before going out on the road. The tires have to be at ambient temp, for accurate results.If you bleed 2 psi out of a hot tire, you may find the next morning, that you actually let out 4.

You can speed the pressure search up by measuring the tread temp with an IR gun, after the tires have run steady-state in a straight line, long enough for the temp to have stabilized.. You will have to take several samples in each of the rows of treads, on similarly-sized blocks, and average them out; then do the same for each of the other ribs. And finally evaluate the cross-tread temp. and make a decision.
On a sticky performance tire the temp comes up fast on the working ribs and you can see the trend starting in a mile or less.
But BFGs are pokey in coming up, so don't hurry. I regularly travel 15 to 25 miles straight on concrete to anywhere I want to go. And so I used to get out several times on the trip to check.

Having said all that, this assumes your front tires are pointing dead ahead under cruising. If your alignment is out, it will heat the tires more on one side than on the other; so if you see that,don't get confused, get an alignment,lol.
Rear tires will usually show the trends sooner, cuz, well, you know; they are often putting on more miles than the odo is showing.

Our Canadian exchange was 1.33 the last time I bought something in the USA. That is 1 buck American cost me $1.33 to purchase.
Hang tuff, that might all change in the coming months.
