Tire Pressure

[Davidbr_48]

What tire pressures would be good for my Mk IV Roadster? I've got Nitto 550s all around (245/45 in front, 315/35 in the rear), 3-link rear suspension, Coyote engine and TKO 600 transmission. I use the car for street driving only. Roads are generally dry here in Arizona, and I don't drive the Roadster on dirt roads - just nice smooth pavement (except for potholes...).

I'm on Kuhmo Ecsta XS's and running 22-23psi with my IRS MKIV Coyote - feels about right and tread contact pattern looks good too.

I was told rule-of-thumb is 1psi/100lbs. So ~23psi is also what I run.

I run 23 front / 24 rear on Khumos.

[Jeff Kleiner]

22-ish.

What pressure would you recommend for billboards?

Start at 22 pounds and check your ride, most people start with way too much air pressure and then hate the ride quality.

Sidewall height is also going to dictate what pressure you run. The shorter the sidewall, the less pressure.
I'm running 18" wheels and tires and typically air the fronts at 18* and the rears at 18.5-19*.
Find a happy medium between good ride quality and tire wear.
