What tire pressure would you guys suggest for my 1930 CCPU? Operating above 5000 feet here in Montana, a few days in the 90's, but usually 70's and 80's for summer highs. Thanks, John

I run 35 psi at 7,600' elevation.

John Butts in CT · 06-04-2012, 02:34 PM

35 psi since 1967... as Ford prescribed. No worries.

Michael in Sedona · 06-04-2012, 04:38 PM

35 psi at 4500 feet here in Sedona. Hot weather in summer, cold in winter.

35 all around on my coupe,tudor & sport coupe. 35 on fronts and 40 on rears of my station wagon and deluxe delivery because they are heavy in the rear.

35 psi at 72 feet above sea level (elevation should not enter into consideration, inasmuch as I believe tire pressure is measured relative to the ambient atmospheric pressure - that is, as psig; pounds per square inch gauge - rather than psia; pounds per square inch absolute).

Another 35 PSI here.

It is my understanding that the brand of the tire will dictate the tire pressure. When I bought my 29 Tudor it had new tires and I noticed the tube valve stem was projecting from one wheel on an angle. I read that some of the lower priced tires requires 55 psi. to prevent this.
That is what I keep on my tires and no problems. However, most tires recommend 35psi.

55 psi! Wow! To paraphrase Paul Simon's Gospel; "[Drives] Me Like A Rock."

Generaly,the only reason you see tire valve stems on an angle is because the stems were not positioned properly in the first place.35# is the correct pressure on all except the rears on some commercial body styles.55# is way to much & will only wear out the tires quicker & be rough rideing.

Because of atmospheric pressure being what it is at 5000 feet you fill it to the 35 psi at that level but it you drive down to say 2000 feet the outside presure is higher and will drop you tire pressure so you need to add more to bring it back up but if you drive back up to 5000 feet you need to let out some air to bring the inside pressure down to 35 psi like was if you drive from 5000 to 7400 feet. hope that makes sense
