Airbags installation for heavy 5th wheel
I made a video of my airbags installation on the truck a few weeks ago. My 5th wheel tows much more confidently, less bouncy with the extra support. For any interested: https://www.youtube.com/watc...

To everyone saying 80 PSI, this is not the case. The tire sidewall says:
LOAD RANGE E MAX LOAD 1700 kg (3750 PSI) AT 450 KPA (65 PSI) COLD.
The tire is Toyo RT 37X12.50R20LT 126Q 10 P.R.
Note that it is a 10 ply, not a 12 ply. Regardless, we can't say "E rated means 80 psi" anymore.
Bounce, Bounce, Bounce!!! The "D" tires are NOT good for hauling a 5er. Carrying capacity, YES but sidewall stability NO!
Sounds like you made a stop at LesSchwab!
I think you misread the above. Note the tire sidewall. They are E tires, not D. I don't notice any bounce with the tires at 65 psi and the airbags at 85 psi. The bouncing was happening BEFORE I put the airbags on and is nearly non-existent WITH the airbags. I drove over some good highway rollers a few times on the last outing and was grateful for them.
Thank you! I stand corrected. My Son ran some Nitto's that were "E" and 65. We had friends that LS talked them into "D" tires that had more "capacity" then the "E" tires they were running. LS bought them new tires after they were completely worn out with no more than 10k.
