What PSI in BFG 245/60's

[Hood]

After fifty years I'm now driving on my first set of radial tires on my Cuda. Man, what a major difference from bias ply tires, for the good! My question is how much air pressure should I set them at...I have them at 33 PSI.
BFG 245/60/14

[Filthy Filbert]

That sounds like a good pressure to start at.

what is the width of the rims ??   I have 235x60x14 tires on my Chally with 8" rims.   I used to keep my air pressure between 33-35 and the tires wore on the inside way more than the outside.   I have since reduced my pressure to 28 psi.

Inside vs outside sounds like an alignment issue of some sort.   Incorrect tire pressures will usually result in uneven wear in the middle vs edges.  Too much pressure, the tire balloons out and wears down the middle of the tread, too little pressure and the middle 'sinks in' and the wear is on the edges.

I understood it to mean the center(inside) of the tire is worn more then the outside(s) of the tire = over inflation

33 sounds high. Wheel width plays a big part. If it's on a 7 inch rim I would initially try 28 front and 26 rear.

35 is max pressure for ta's.I leave them at 35 because my car is not driven that much and the tires will lose pressure over time.

I run at 35psi... and yes BFG's

Run nitrogen in the tires. It removes moisture from inside the tires, their larger molecules penetrate the inner liner  at a much slower rate reducing pressure loss. They are less affected by temperature the way that regular air does. Air from a compressor also contains moisture(water). The percentage depends on the compressor and how ell it is maintained and filtered. Always haveyour own, quality air gauge.
That tire size is a couple of sizes larger than stock from a load carrying standpoint and can run less air because of that and still be safe. Depends on the rim width, and the way you drive. Regular cruising...26-28 lbs would be just fine. Good ride and wear.
Spirited driving(fast) run a few lbs more. This will tighten up cornering and steering wheel response. 30 + lbs of pressure is really more than you would ever need unless you do a lot of hi-speed driving and carry a lot of stuff in the trunk or tow.
You can get an idea of how the tire wears by taking some tire chalk and drawing a line across the tread on each tire. Drive a normal route you drive and then check the lines. If it is worn off on the outside edges, increase the pressure slightly and recheck. If it is worn down the center  (and not the rears from spinning them), decrease the pressure slightly and retest. Every car and every driver are different.
Your front tires because of the extra width over the stock size will have a tendency to wear on the outer edges because of scrubbing, especially if you corner a lot.
Be sure to get a good alignment now that you have a new set of tires so they develop a good wear pattern right away.
Once you tires develop a wear pattern it is very difficult top correct it since the rubber is worn off.
78% inert<100%  Both are acceptable but 1 is better. You just decide which one you prefer.

This is general advice and it doesn't matter what brand of tire you use. Contrary to a few peoples opinions

Run nitrogen in the tires.

Well if you just fill the tire with regular air that would be 78% nitrogen......jus sayin'

Well I would inflate them to around 250 -500 PSI but from a distance though  [ where is the guys running for his life emoje ? ] at least that way you car shouldn't get damaged while driving on them  & when they splode put real tires on ....

I ran BFG`s for 27+ years, around 28 psi on the street and dropped to 15 psi for the dragway - never an issue and wore great.
