Wheel tourque and tire pressure?

I have a 2013 Jayco series sport 8. Does any one know the correct "wheel torque" and "tire pressure" for this?.... Thanks in advance!!

The tire pressure should be on a label affixed to the trailer, I would guess it's 50psi. Your lug nut specs will be in the owners manual.

Wow!!! 90 PSIG is seems high for a load range "C" tire! Just sayin! Every Load Range "C" trailer tire I have ever seen has a max tire pressure listed on the tire of 50 PSIG (14", 15").

(EDIT) (I stand corrected!!!! Just googled a 12 inch load range "C" trailer tire and find that it has a load rating of 990# at 90 PSIG max... Go figure! Guess it pays to check the tire size!)

Yeah, I am fairly certain it would be 50psi. I did look up the torque specs, the acceptable range is 50-75ft/lbs.

Sorry - those tire types weren't qualified....post deleted!!!

Jaycos website identifies the 2012 Sport Series as being shipped Load Range C

If you dont have a factory sticker....It's important to identify the identify the tire to determine the proper max pressure and stay with that......

Special Trailer Service Tires (ST)
Special Trailer Service tires are often available in multiple load ranges. The appropriate load range is identified immediately following the size's rim diameter in Tire Rack's descriptions.

ST-Metric sized special trailer service tires will be branded with their load range (Load Range D or LRD) on their sidewalls and list their appropriate load range letter in their descriptions as ST205/75R15 LRD.

Load Range Ply Rating Max Load Pressure
B 4 35 psi (240 kPa)
C 6 50 psi (350 kPa)
D 8 65 psi (450 kPa)
E 10 80 psi (550 kPa)

There....that looks better

For proper wheel lug torque - you will need to refer to your manufacturers documentation for the "official" statement.

Following are (2) excerpts from Dexters manual on lug torquing specific to Dexters steel wheels 2004 and back....
