Question:

One wheel had major damage to the wheel lugs. We have some temporaries on there now but I really want to get the correct lugs and lug nuts. The model is 3691SK. I hope you can help. Thanks.

Expert Reply:

According to my research your 2013 Heartland Big Country 3691SK uses 235/80-16 tires with a 16 inch wheel like the Castle Rock ST235/80R16 Radial Trailer Tire with 16" Silver Mod Wheel # LHACK133 with a hub that has either
1/2 inch studs like # 42866UC3 or 9/16" studs like # 8-219-13UC3.

We don't have any way of knowing which is on your specific trailer so the only way to know is to measure with a digital caliper like # PTW80157.

Once you do know you will need either:

- 1/2"-20 Trailer Wheel Lug Nut # LHLR103

- 9/16"-18 Trailer Wheel Lug Nut # LHLR110
