Tyre Air Pressure.

[sotsira]

is tyre pressure that important. I had a Isuzu Grand Adventure for 7 years. Ran the tyres at 33. Never a problem. I now have a PJS and run all 4 tyres at 35. Still no problems. I think I drive at sensible speeds (140 max, mostly 100 -120) so maybe it is not an issue. Experts - am I being unsafe?

Speeds are highway driving btw

Open the drivers door and a sticker on the door post will reveal all. Manufactures test their new vehicles to the extreme to provide a safe pressure for it. These are ''cold'' pressures, which means check before going on long run or tear- assing around . Tyre pressures rise as the tyre gets warm via driving.

The tyres (size) fitted to my vehicle are not dictated on the vehicle placard. what should I run them at ?

Trial & error until you feel the handling is to your liking.

Ask the manufacturer . Easy stuff for an ex racer like yourself. We have all done it eh.

Have you got Falken's number handy ?

I would go much higher, 52PSI in my truck.

Tommo, you're putting us on, right? I don't think you are that stupid. Tell me that it is a spoof post.

Yeah I was just poking the TrannyMan, I run em at 32 front and 30 rear. I don;t carry loads in my pickup.

My pickup has light truck tyres rated at a max 65 psi cold.

I've been running at them at 52 psi for more than a year now, no problems.

He has none standard tyres fitted for load and not comfort or suspension life longevity.
