About a 3900 lb truck, magnum 360, still stock stall atm(rated at 1670 rpm w/stock engine but only a [email protected] cam vs 194 @.050 stock) Compression bumped .25 approx. BUT 4.88 gear set.

The tires are the 295/55/15's and I'm guessing the weight distribution is around 65/35. Shouldn't have a lot of traction problems yet don't think it will bog either. What would be a good guess of a pressure to start with for a decent contact patch keeping the rolling resistance down?

May have given to little or too much info, not sure :)

I'd suggest starting at 19 and working down (or up) as needed.

^ Agreed. I usually suggest 20lbs starting off. The more air you can put in them, the faster you should go.

Ok, thank you. I'll start at 20 and work my way up. Traction should be plenty even with stock suspension and stock stall. Should have went smaller but was planning on the 408 I machined/assembled to be in it. It's sold now unfortunately.
