What tire pressure are you running on your E1 load range tires?

I see max PSI is 80 and I assume that's probably best for fuel economy, but do you guys run them that high? Sounds like one hell of a stiff ride?

 

I only run the max PSI as stated on the tire on my trailer tires. My truck came with D rated BFGs and door sticker states 46 which is about right. I had very even wear when I replaced at 70k. I now have same tires in E rated and run at 50. 80 PSI will definitely be rough. Max PSI is just that.

Thanks, this will be my first set of E rated tires so don’t really know what an appropriate pressure is.

 

Bruce apply some sidwalk chalk to a section of the tread and you can see where the chalk wears to tell if you have too much or too little pressure. I suggest around 40 psi for E tires. They are stiffer so will ride rougher in my experience.

 

80...Holy schnikeys. I don't have a '22, but on my Tundra am running 40-42 on E rated tires. I will run 70 psi on the diesel (E rated), but that thing is a heavy biatch compared to the Tundra

 

This is an excellent tool for getting air pressure correct when moving to a different tire size or load rating.

 

I am running at 50 PSI. When I had them rotated and balanced they dropped me to around 40 and I lost a bit of MPG. I haven't come close to running at 80 however 50 seems to be a sweet spot.

 

I'm pretty close to where I need to be. I have aftermarket bumpers, a truck box full of gear, etc so I think my 35 psi is about right. I'm always looking at tread wear for irregularities

 

Thanks I may have to give this a try!

 

that pressure calculator will get you really close. Chalk test will dial in in further
