Wheel lug torque for 310 GK?

[JM0397]

I’ve looked high and low, don’t see anything but a torque order diagram on my pin box, but it’s for the wrong lugnut configuration!
I have: ‘21 310 GK, factory setup, 8-lug Lionsheads wheels.
What’s the torque recommendation?
I think 100-120?

Thanks!

There's an entire section in your owner's manual. Need to identify your lug stud diameter. If you just have standard 7K axles the studs are 1/2-inch.

I’ll check The manual again, but it was vague and not helpful on first pass - thanks!

There’s a sticker on the pin box of my unit that shows lug torque. I’m not sure if GD or the dealer put that on there. Most of the ink wore off but it does say 120. I agree the manual doesn’t make it real clear.

120lbs is standard for 1/2" lugs

Thanks all, I think they put a wrong 5-lug sticker on my pin box.

Dexter’s manual says no greater than 120 ft lbs. I torque to 110 ft lbs.

Straight out of the Owner's manual.

Right, but with the rig parked in storage, I wasn’t sure the configuration other than 8 lugs and I think we have the 17.5” rims, so no guessing after all, if that’s the case.
I have some rig work to do tomorrow, so I’ll check and report back for clarity.

My little sticker for 17.5-inch rims with H-rated tires indicated torqued to 130 lbs.

What size are the studs for the lug nuts (1/2" or 9/16")? The charts I have from Dexter show 9/16" for 17.5" wheels, but I have heard of 1/2" with some 17.5" wheels. Do you know if the rims have steel inserts in them? I assume the wheels (rims) are aluminum.

Yeah I bought a 310GK in February and it definitely has 17.5 inch tires. I hope their chart needs updating.
Based on that information alone (17.5 inch size) one would be inclined to torque 190 to 210 OR 275-325 (??!!)

Torque is based on lug bolt size, not tire or wheel size.

The chart supplied by Grand Design does not support that logic. I'm sure you re correct, but a newbie like me might just see the 2 entries at the bottom ( the only 2 with 17.5 inch rims listed ), and go way overboard with the torque. If there are 17.5 inch rims with smaller lug bolts, they should ALSO be listed, because right now I think the chart is misleading if you don't have much experience with the whole torque thing (which I don't). That was my point.

Maybe you only need to tighten 5 of them and the other three are spares!

LOL - yep!
Thanks everyone. We're on the road this week and it is indeed 130 on the lug torque. All went well and the new TPMS (TireTracker TT-600) works great!
