Hi, I’ve read many different perspectives on tire replacement for the GMC.
Upon delivery we noticed that one of our tires is flat, (passenger-rear)
and are going to need to replace it. All of our tires look good they’re
under 5k miles, so just curious should we order two and put them in the
front and swap the front ones back like the previous blog entries say?
Looking forward to your input thank you
RaeRae
Hoping our signature attaches

RaeRae,
Thread unless your are a real road warrior in your GMC, thread wear is almost a non-issue. Tire date is everything.
To find it read https://www.tirebuyer.com/education/how-to-determine-the-age-of-your-tires#, then go find that on all seven tires and write the dates in the maintenance log that you should be keeping.
You should have a maintenance log book. If you did not get one with the coach, buy a book and start one now. If you do this right, this will all be a blur in not very long. "Is the main engine battery really that old?" (Yes, it was!)
If you do not have all the service and operator manuals and such they can be down loaded at the GMCMI site.
You did not say how much of a technician you are, but you asked about the carried kit and that is good. We have found that there are few that we can hire to do the work that these coaches need regardless of cost. There is a lot more maintenance to them than there is with a modern "appliance" cars built recently. If you don't own a grease gun and other tools, you may choose to buy them soon. You can come here and ask questions always. As said before, we love helping owners. The only thing we like more is keeping owners from making expensive mistakes.
I hope you are ready, because travel, particularly with a family is very different than anything you have done.....
When you fly, your schedule is completely at the whim of the airline and you get to drag your luggage everywhere and wait hours in the terminal. Hopefully you have reservations where needed and plans to feed the kids.
When you do a road trip, apart from the map work, your biggest issues are where will you eat and where will you sleep.
When traveling in your own coach, you have no luggage, where you will eat and sleep is right behind the driver and you really don't need a cramp ground unless you want to. Doing an EOD (End of Day) ONP (Over Night Park) can be anyplace that it is level and legal.
Now the big effort becomes enjoying the journey. Get the kids set up with enroute games or have them read the guide books about the places you are going.
Welcome RaeRea and Caryn

In short if you have 3 digit date codes they are over 20 years old and time to recycle them. If 4 digits last 2 are year. Most say recycle them at 7 years. I have gone longer on Michelin tires stored indoors and kept at correct inflation, balance and vehicle alignment with zero issues. 225/75R-16 E load range if you have 16” radial capable wheels. Steel belted, polyester carcass such as the Cooper HT3 for example for “mud and snow” rated all season tire.

FWIW,
I have had 2 blowouts (one at ~75mph which cost me a T-skirt, some body fiberglass and a hubcap), both on the same hot summer day. Both were apparently due to age (~8 yrs)of tire, or just crummy Bridgestones. Both had 80-90% tread left. Significantly, both were on the leading rear wheels. My theory is that those wheels get dragged sideways whenever you make a sharp turn which may shorten their life. At lest with tandem rear wheels it was easy to maintain control.
In any case, I would first make sure both front tires are identical and fairly new, but then I would put my best tires on the leading rear wheels. If all tires are of similar age, I would rotate them yearly.
My 2¢, YMMV

I saw the results of several blowouts on a number of coaches. One that had
flared rear fenderwells, and custom paint cost over $4000.00 to repair. If
yours are older than 6 years, I strongly suggest that you consider
replacing them, no matter how much tread life is left.
