air pressure

[hotrod68]

Testing my new to me dart tomorrow, tire size is 33x14.5 what's a good starting point for air pressure? This my 1st big tire car, square tube chassis 70 dart 440 B-1 headed koeffels motor. Thanks for any info it has taken me over a year to get this thing ready.

bias ply slick? maybe around 12, radial usually more. suspension type, convertor lauch etc etc will change that stuff a bit
