Trailer tires will time-out at the end of this season. The stock steel wheels are already rusting after only 3 years of light travel. I have also lost 2 hubcaps ($25 ea), replacing the first one but deciding to invest the next $25 into new aluminum wheels instead. I know that I need to match load rating and pressure. There is also mention of an offset. Do trailer wheels have different offsets? If yes, how do I determine the offset that I have?
