Hancook Product Info PDF Includes pressure to weight table but the table does not appear to make a distinction between load range types.
Based on the available info for an A11 245/70R19.5 80 psi or maybe even 85 psi will keep the tires well above 14,500 lbs. 80 psi puts the limit at 14,540 lbs which might be a bit to close and easy to go past when you're running close to that limit while 87 puts you up into 15,580 lbs which is well past what is needed. Maybe 85 psi will be a good middle ground. Not too high but will allow for variation as the season air temps start to drop. Plus an easy to remember number.
