What is a good starting point on tire pressure for these tires, mine are 275/60/15.

I use 275/50's on my car, but several friends have them on there cars with assorted sizes and all range from 15-19 psi.

Mine run best at 16psi and I use one air bag at 24psi in the right rear and my car goes mid to high 1.50's 60ft all day long with those tires.

FYI- I found that mine worked best getting them hotter than I thought I needed to.

Thanks, I had mine at 18lbs and I was blowing away the tires with 2.0-2.2 60 fts 12.60's@110, next time I will try 16lbs or so and more heating them up.
