Correct trailer tire psi & torque?
 

Tri-axle w/ alum rims. What psi & torque on rims would you run at?

My Eagle trailer has a spec sticker attached to it. 80psi. for the recommended tire size and type.

100 ft lbs. according to the owners manual. Aluminum 8 lug rims.

Depends on the tire rating, most "D" ranges are 65psi max (I run my tires MAX).
As stated, "E"s are 80 PSI.

The PSI is printed on the tire. As for torque, I use the calibrated elbow. :)

Wow, ask a question, go eat dinner & I've got answers, cool!

thks guys :boat:

so you think 100 ft lbs on rims?

bl,
Dont guess on the rims. Find out the manufacturer and call them or call the trailer manufacturer and ask them. Make them too loose and they can come off, make them too tight and they can break. You need to find out the correct torque for your aluminum wheels and the lugs that you have. You cannot go by what someone elses trailer requires.

Just my opinion,

Not a good idea, imho. That psi number on the sidewall is for the max pressure and max loading. Weigh your rig, get a pressure/load chart and inflate your tires properly. I've seen too many wheels damaged, studs stripped or broken from incorrect torque. Don't guess, find the specs - they vary depending on stud diameter - and use a torque wrench, or if your lazy, (like me) get a torque stick of the correct rating and use your impact wrench.

My boating buddy who works for the TireRack told me 80 ft lbs on alum rims.

Based on what experience and knowledge? What mfr rim? Size? Lug stud diameter? Nut seat design? Application?

One size does NOT fit all here.

bl,
Dont get us wrong, we are not trying to be hard on you, but there are just too many variables involved to guess at this. Just to give you an example, I had new tires put on my Tahoe a few years ago. When I got home, I checked the lugs and they took quite a bit to get them to the proper torque, which is 130lbs. I called the tire place and they basically told me the same thing your buddy did .... we torque all aluminum wheels to "###" So much for that tire place :( You absolutely have to find the correct torque spec for your wheels on your trailer.

Be safe :)
