Tires February 28, 2022, 01:27:19 pm Hello,I purchased all new Toyo tires nearly 5 years and have read tires should be replaced at 5 or 6 years regardless of wear. American tires said this is due to UV but I have read it is due material deterioration over time. My tires have low mileage and negligible wear and have always been covered and protected from sunlight. I move the vehicle occasionally and keep the tires at max air pressure. I was wondering if the 5 or 6 year rule might be a bit conservative. What do you think?Thank you,Matt
Re: Tires Reply #1 – February 28, 2022, 01:33:18 pm It does seem silly to replace tires that 'look' fine and have plenty of tread left, but the cost of a blowout and the damage it can cause to your rig is substantial. I always waffle back and forth and then go ahead and replace them around 6 years. Between the weight of the rig, and the heat of summer where I live, I'd rather not deal with a torn up wheel well. To that end, I ( and others) have added a Larry Wade style heat shield to the exhaust pipe.Exhaust heat shields | FlickrRich 1 Likes
Re: Tires Reply #2 – February 28, 2022, 02:22:02 pm Hi rich,I also had a heat shield installed at a muffler shop. I do not notice a difference though. I will attach a pic tomorrow. My passenger side rear tires definitely run hotter than the other tires. I lost a tire once on the way in Mt. Lassen. 110 deg. on the I5 did it I think. But not while on the I5. The tire came apart the following day in Lassen at slow speeds in cold temperatures. I run the RV with high tire pressures, 65 PSI front and 80 PSI rear per the LD manual. Thinking of running the rear tires at 75 PSI. Thank you,Matt 1 Likes
Re: Tires Reply #3 – March 01, 2022, 08:38:11 am Small cracks on the side wall is a sure sign, had this on older VW's. You would want to replace before then. I think the first trip over an hour long after I hit five or six years I will replace my tires.
Re: Tires Reply #4 – March 01, 2022, 01:41:51 pm Unless your LD is stored in a vacuum, the ozone in the air slowly deteriorated the tires, no matter if the tires have low miles.We had a 5-1/2 year rear tire blow a few years ago and it wasn't a good experience, it did a bit of damage.I have added exhaust shields and now rotate the rear tires every two years.New tires are expensive, we all agree on this. The damage of a rear tire blowout can be extreme, possibly causing thousands of dollars worth of damage. At the Mothership I once saw an LD with everything above the passenger-side rear tire torn up, the blown tire took out the water heater, furnace, and refrigerator, it also caused major body damage. A new set of tires would have been much cheaper.Larry 2 Likes
Re: Tires Reply #5 – March 01, 2022, 01:56:53 pm It’s also known that a good TPMS will let you know of slow leaks and such but a catastrophic Blowout has no such warning. Blowouts are not good. Aged tires are known to cause such occurrences. Just sayin’Kent 2 Likes
Re: Tires Reply #6 – March 01, 2022, 02:54:22 pm We had an inside, driver side rear tire catastrophically blow. It had ample tread, was inflated properly, but was about five years old. I subsequently replaced all of the tires, even though they looked fine.Harold

Blowouts are not good. Aged tires are known to cause such occurrences. A few minutes before our passenger side rear tire blew, I had checked the pressure of all ten tires and everything was fine.The TPMS did alarm within a second or two after the blowout. The passenger-side rear tire is the most common tire to blow due to its close proximity to the exhaust pipe. Heat shields and periodic rotation should reduce this occurrence.Larry 1 Likes
Re: Tires Reply #8 – March 03, 2022, 01:21:48 pm This information is compelling enough that it leaves room for not replacing the tires at 6 years. Cost of ownership. Thank you!!! Matt Jones
Re: Tires Reply #9 – March 03, 2022, 01:36:47 pm "All About Tires"? If you're referring to "About Your Tires...", it's a document that I put together a few years ago and updated regularly for some time after that. The document on The Companion does contain basic information that is still current and valid, but tire brand suggestions, website links, and other information have not been updated and may not be current; just a FYI.

Re: Tires Reply #11 – March 25, 2022, 01:15:07 pm In June 2000 we were driving on Rt 26 from Seaside to Portland an about 50 miles an hour when a pickup pulling an RV trailer pulled across road to get some coffee directly in front of us maybe some 300ft. I hit the brakes harder then I have ever hit them before and we stopped inches from disaster. Everything that was loose including items from our bed in the back lounge in our 98~MB was now with us in the front cab. We survived and all looked OK, I checked our tires too. A few days later we were at Sparks lake in the Cascade lakes in Oregon, we parked in a spot near the lake. Some people asked if we saw a part that was missing from their Kayak trailer parked earlier in our spot. I checked under our LD. I saw our passenger inside rear tire with a large chunk missing. The sparks lake road in from the paved cascade lakes road is about two miles of washboard dirt road. We called Coach-Net and waited for a rescue which never came. We decided to drive back to Bend later in the evening which is about 35 miles away mostly down hill. We drove at 20 miles an hour all the way there, the tire held out and we got it changed at Les Schwab the next day. Based on the condition of the other four rear tires we changed all four, Les Schwab gave us credit for three of the four tires which were still in warranty and were only four years old. Apparently that emergency stop may have caused damage to the tires unseen till they were driven on some three hundred miles?

If so, did they indicate why the truck didn't show up? Location? Road surface? CYA waffling/lame excuses? 1 Likes
Re: Tires Reply #14 – March 25, 2022, 02:08:41 pm One more thing for me to find in the Bay Area.The tires on my new rig are practically new, but they are coming up on six years this fall.
Re: Tires Reply #15 – March 25, 2022, 02:23:00 pm Hi Dave...OOOOh a cardinal sin; "tires on my new rig are practically new" Unworn looking tread should not be confused with age. That date code is there for a reason, and is the dominant factor of tire condition. And a beautiful looking rig it is! RonB

Re: Tires Reply #17 – March 30, 2022, 07:45:00 pm I’ve been using Michelin ltx-ms tires for some years which apparently have been replaced by Agilis CrossClimate which run $271 each. Can anyone recommend another brand?

Re: Tires Reply #19 – March 31, 2022, 09:13:22 am I have been using the Hercules Terra Trac Cross V for two years and 8000 miles. I would buy them again. 1200 for 6, installed including taxes.
Re: Tires Reply #20 – March 31, 2022, 12:21:22 pm 6 Agilis Crossclimate cost me $304 each in Folsom last year, replacing tires varying age 3-6 years including install of extended valves. May be a bit more than elsewhere but convenience and trust were a consideration, as was that a new tire was cheaper than he deductable for damage when an old one blew. Spare is 1 yo so I'm satisfied with tire condition.
Re: Tires Reply #21 – April 05, 2022, 09:16:31 am I’ve heard that when replacing tires, folks take the best of the old tires and use it as the spare.But since I am replacing the original tires from the mothership, by definition the original spare is the tire in the best condition.
Re: Tires Reply #22 – April 05, 2022, 09:31:52 am Since you have such low miles...keep the original spare. Use for a couple more years. If you ever pick up a nail in of of the new 6....patch it on the inside..no plugs....then make it your spare and put a new tire on the rim of the one you got the flat on. This way you still have a good spare. No sense having an expensive tire just hanging back there dry rotting....if a couple of years pass and it gets to be seven yrs....buy a new one for the spare.....then you will have a new tire when you pick up a nail in one of the 6 on the ground...Get a good tire pressure and temperature sensor set up. I have the tire minder.Gives me peace of mind when traveling.

Last year I replaced six tires and kept the original spare since it was not used and had been hidden in it’s dark cave for 5 years. However, the new tires are Cross Climates and the originals were LTX, I think, so that could be an issue.
Re: Tires Reply #24 – April 05, 2022, 12:17:38 pm Another approach is to buy seven new tires and add the spare into the front tire rotations, done every 5-6000 miles.The rear duals wear more evenly, with extended valve stems on the rear tire, I rotate the rear tires are every other year, swapping the rear tires from side to side to spread the heat damage to the passenger side rear inside tire.Larry 2 Likes
