Adding a tow car will not change the rear or tag axle pressures required as all weight that's added should be less than 100#'s total.
Diesel = 7.15#'s/US gal
Water = 8.35#'s/US gal
On our DSDP I have about 13,200 on the front axle and run my 305/70's at 100 psi.
Rear axle is just under 19,000 on 275/70's, I run 90 psi.
