So, is this the worst thing ever to put on a LR4? It's kind of enticing because I have a set of 18" rims with snow tires. I would only do it for the winter (maybe 4 months), easy driving. I've read some anecdotal stories about them falling off and whatnot. But if they were torqued right, checked, and only used for about 4000 miles a year, what do you think?
