    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!
