I had to convert mine from 8x165 to 8x170. When I did I made it so the tire was actually resting on the bumper so not all the weight of a heavy 9” rim and a 35” tire weren’t just floating. It’s cut down how often I have to retighten all the bolts.
I am going to try that washer trick though for a more secure latch. Thanks for the tip langan!
