Tire pressure dual drive tires

For Goodride the only safe tire pressure is 0.....

I'd run 105 summertime

 

I run what the tire says.

 

I go by what is recommended from the truck manufacturer..it’s listed on the door jamb.

My steers are set at 120 and my drives 95

 

I wouldn’t go by the manufacturer of the vehicle. For example on my trailer to get the max weight the vin plaque says tires need to be 125 psi. Which is ridiculous. Your truck could be set up for a 40k or higher tandems so what’s printed in the door jam is to haul that max weight. However it’s pointless as you probably only haul 34k on it.

Every vehicle is a bit different. For me I do 105 trailer (low pro 22.5) spread axle flatbed. If I was a dry van I would do maybe 95.

My steers I do 105 psi as they are 11r24.5 and that’s what they are rated at. If I had a low pro 22.5 I would do 110.

For truck I run a beefy 16 ply 11r24.5 tire and to get the max rating it can be aired to 125 psi. I run it at 80 psi. According to the Michelin chart I can still maintain over 34k on the drives even at 70 psi. I started at 95 psi and I ended up at 80 psi by hauling 34k on the drives and seeing how the tire sits. Anything higher than 80 psi only the center 4” of tread was touching pavement.

 

I run everything at 100 psi

 

Driver tires have been 110-115 for me.

 

Not an O/O, but...

I run 95-100 in my steers and 100-110 everywhere else, reguardless of what I'm under. Never had an issue with tire wear or ride due to air pressure in those ranges.
