In October of 2020, WE bought our first 5th wheel, a 2015 Heartland cyclone 4150. From what we can tell, it was left on a seasonal site since 2016. I am thinking the tires are original, and although they look almost new, I am planning on replacing them as it sounds like dry rot is a problem when a tire gets this old. The tires that are on it are E-rated. This is a triple axle coach with a 20,000 lb GVWR. When I did the math with the tire weight capacity that was listed on the tire, there was only 540 lbs left if the TH was fully loaded (which I doubt I will ever come close too). Does this seem odd that the TH would have come with these tires from the factory? I am thinking I need to put "G" rated tires on it when I replace these. My local small town tire shop recommended: "G" rated not only for the extra capacity but also said they have never seen a "G" rated tire shred on a 5th wheel. The price is about $210 per tire vs. $170 for the E rated. I have no problem spending the extra money, but just wanted opinions from those who have been doing this longer than I have

Actually I'm not surprised they came with E's - they are cheaper and that's what the manufacturer goes for. What tire is your dealer recommending is the next big question?

Then buy the Good Sam Emergency roadside service plan for break downs and changing tires??????

The problem with trailer tires is the tread gets little wear so they almost always look great unless there has been abnormal wear. Normally they'll age out or have signs of dry rot before the tread looks worn. I buy Sailuns because I only run my "H" rated tires 15,000 - 20,000 miles and they are less expensive. YMMV

I don't remember the brand my local guy recommended a it was back in November that he quoted me, but I know he is a "Buy american guy" so I am assuming it is an american made tire

I finally, after two blowouts, went to G rated tires on my 5th wheel and have been pleased! I highly recommend upgrading to the higher load range.
