I have a 2017 Bighorn 3575EL with original Sailun tires date code August 2016. They have very few miles on them, 4000 or less, not that that matters! What is considered time out on these tires?
I do think that most of us look at 5 years as a kind of benchmark to start thinking about replacing tires. I also think that this unwritten tire replacing rule has a lot of factors that should be entered into one’s final decision to replace them. Some of the factors could be make of the tires, mileage on the tires, how the tires are being used, age of the tires, among other considerations including storage, exposure to sunlight, weight of the rig, etc.
Cost usually does enter into it, but I look at tire cost as a kind of insurance. Why? Because I’m one of those that tried to get one more trip out of a set of Carlisle’s, the tires that were on my rig when I purchased it. In the future, I’ll replace a quality tire at the 5 year mark of when they were installed, not when they were made. I’ll fudge that much.
And to add, if the tire currently in use is not one of the so called, RV user preferred brands, I’d probably take them off tomorrow.
