Exclamation What is the best way to get all my tires changed?

My 41 foot 2019 380TH Montana high country has six tires, three on either side although all the manufacturers pictures and description say itís only a two axle model with 4 tires. I am a newbie in this is my first RV so I donít know what I donít know. I have taken it out five times of distances no more than 2 Hour drives and have had blowouts twice. The first blow out was a freakish accident. The second one I have no idea. I want to swap all six tires and two spares for 12 ply new tires. I donít want to go to a dealer because I know I will pay a premium for the tires. I was thinking of changing them all myself, but that task is to daunting. Removing all six and the one blowout spare that I have, Plus finding a rim for the second spare that I want, taking them to the tire shop and getting them replaced, then mounting them all back on it seems probably too much of a job for me alone.

Any suggestions on where to buy the tires at the best price?

What size and ply tires are on there now? What is the year/month date of those tires (you don't want anything more then 4 years old). Given you have 6 tires I assume they are likely "E" or possibly "F" rated. "G' rated tires would be a definite overkill.

The are many places to buy tires. Online sites like Simpletire.com, TireRack.com or even Walmart will deliver directly to you. Big O, Discount Tire, aka Americas Tire, stores have reasonable prices on a variety of tires. Shop online to find what you want (stick to known brands with a good rep) and the price you want to pay.

For installation, you have two choices. Take the RV to a dealer and have them install the tires (even if you didn't buy from them) is the easiest route. Alternatively, jack up one side of the RV (you have the electric leveling system which probably isn't enough to lift, and hold the RV off the ground), put jack stands under the frame, and remove three wheels. You will want to take them to a tire dealer and have them mount and balance them (Americas Tire will do this for tires you bough elsewhere). When done with one side, repeat on the other. You don't want to try and demount/mount tires yourself.

Personally, I would find the tire I want. If it is at a tire shop, let them install. If they are shipped to me, take them and the RV to a tire shop who will install and balance for you. You are going to wind up a tire shop for mounting so the little additional cost to have them jack up the RV, remove and reinstall the wheels is minimal.

Just an FYI.
In the owners manual it says NOT to jack under the axles (possibly a good way to bend them out of alignment. Make sure they jack under the frame.
Many here recommend Sailun G rated tires, but you have to have rims rated for 110psi. There is a
(110) stamp in the inboard side of the rim.

If your tires are 110 pound tires don’t inflate them on 80 pound rims over 80 pounds.

When I ordered thru simpletire.com, they had a couple of local installers I could choose from. I had the tires drop-shipped to the one I chose, and they had enough space for the FW so I just drove it over. If you can't find an installer with a big enough space, you could jack up one side at a time and deliver the tires/wheels to your installer.

The sales brochure for the 2019 HC shows he should have 110 psi wheels already installed.

When we were at the Les Schwab in Crescent City, California getting a truck tire patched they had a 5th wheel RV outside doing the tires with portable jacks. The exact route I would take.

Thanks, I’ve been told by various people to go 12 ply and I’m pretty sure they are an F. I’m glad my assumption that to have a dealer put them on meant I needed to buy from them. Unfortunately it’s around midnight and cold so I won’t run out there right now to check the letter. I think I’ll buy 6 new 12 ply quality tires, a rim, and put two of the current tires on my one blown spare and the additional rim so that I always have two spares.

Thanks. Yes, I use the frame, not an axle.

That's interesting. They are all 80 psi. Maybe that's why I have six tires instead of four, but this is a 41', and I think 17,000 lbs ( I need to check on that again, I haven't loaded it up yet)

Don't know if mentioned elsewhere here, but ST tires have a speed limit of 60 or 65 mph. Otherwise, seems like you had plenty of tire - 3 axles at 6800 lb each.

I hate tires. So I googled the speed rating for the factory Rainier's. I have the same tire 10 months old with about 5000 mile on them. I figured to get at least a year out of them. My average speed is around 65 but I have exceeded it on occasion


My point is according to Google you get different answers
https://www.tredittire.com/tire/rainier-st/
  • ST tires are designed specifically for boat, car and utility trailers. They are built to carry heavy loads on non-powered axles and are rated for a maximum speed of 65mph. Their stiff sidewalls help prevent your boat/trailer towing package from swaying

  • How fast can you go on ST tires?
    The rating ST, or special trailer tires, can handle 80 mph and beyond. These can withstand higher speeds while carrying heavy loads and, just like typical trailer tires, come with stiff sidewalls to reduce trailer sway.Sep 4, 2021
Just an example that just because you saw it on the internet it must be true....

I purchased my 14 ply Goodyears from a Goodyear commercial garage. They also installed them. They have all the equipment for large vehicle/trailers.

I never heard or saw anything that said not to take them over 60 mph, I have had it up to 70

It should be stamped on the back side of the rim.
