Question about tire pressure in TV area.

[NORTY FLATZ]

Going 2 PSI above, is better than going 2 PSI below.

As far as "altitude" is concerned, the pressure measured, is the difference between the inside pressure and the outside pressure. So, if the outside pressure is lower, like at altitude, then the inside pressure would be lower, too.

Thanks for the feedback, I'll be going with manufacturer spec from now on.

Ever since I began driving (1969) I've had numerous techs and tire people tell me that 2psi over the recommended pressure from the manufacturer will and DOES indeed increase the overall life of the tire. The primary thing you'll notice is when done this way, the edge of the tire doesn't wear so poorly nor quickly. So it's been my go to forever in the 15 new cars I've owned over the years. Never let me down.

Thank you....I had no idea what TV stood for in this context.


To all - at 2730', Boise is not high altitude. Most definitely not high enough to affect tire pressure recommendation.
