Tire pressure while parked

[Boozecamp]

I'm trashing my 1.5 year old Road King Blow-Max's (three of four have blistered up or blown out, and I'm installing 4 new Goodyear G614's on my 5'er tomorrow. I'm fulltiming right now, on concrete pad. Don't plan on moving for a year or more. These new tires can be inflated to a max 100psi. How much pressure should I put in these tires while parked, so as to maintain good condition.

Also, I've always wondered............we cover our RV tires with vinyl covers for UV protection like they're blonde-headed infants, but I've NEVER EVER seen covers on tires mounted on cars, trucks, boats trailers, motorcycles, etc. What's up with that? And yes....I park my truck in the same place every day so the truck tires see the same amount of sun as my 5er does! :h

First of all, there is no way I would be securing my new G614's under the trailer for a year until I was ready to put them on. $1,400 to $1,800 worth of tires to steal?

I would have them installed. Don't know what the weight of your fiver is, but I would take that into consideration when deciding on exact tire pressure. Also, remember the temperature outside effects your air pressure reading. In other words, if it is 40 degrees when they go on and you have them inflated to 110psi, don't be shocked that in the spring when it hits 75 degrees that they read 115psi. I keep mine slightly below 100 currently.

I don't use covers on my tires. The main reason I don't is because of my slide configuration. My tires are all in the shade 90% of the time. If I needed to cover them I would never use plastic or vinyl covers because they are a scam and will hold moisture and actually cause your tires to rot quicker than UV damage. If you want to protect your tires from UV, keep them clean and coated with 303 like has already been mentioned, and if you do cover them use a high quality screen type cover.

EXACTLY! Our rig, (below) was purchased new in 2014. The tires (Road King "Blow-Max's) looked brand new, only after the 1st of 3 blow-outs, I found out that some dealers buy tires in volume, and store them for new trailers. My call to Road King Warranty informed me my tires were 4 years old, so old (new tires) and chinese may-pops, is my problem. The reason I'm changing all now is: my spare is a recent blow-out (flat), one of the 4 mounted tires has a very large blister the size of a large grapefruit protruding out from the outter sidewall, but still holding pressure. A manager at NTB said a tire was brought to them in same condition, the tire was laying outside near the front door, it blew out while the guy was buying a new tire, and it was a significant explosion that rattled the windows, very Dangerous situation. My next RV will be negotiated with the best tire possible. I was naive about RV tires, no more! :C

I agree. Dont buy tires until you're ready to mount them. Not only are you allowing them to age before ever mounting them but what happens if when you go to mount them and you run into a problem? By then it may be too late to do anything about it. And its not the "sitting" thats bad for tires. They dry out and literally rot which causes ply separation and casing separation. Rubber needs to move to maintain its integrity.

The way it was explained to me, all tires contain compounds to protect vs UV, cracking, etc, and these are "spun out" to the surface of the tire constantly as it rolls down the road. Because our trailers move so much less than a standard vehicle, the protectants don't get well distributed so the trailer tires are more at risk for UV damage.

Good points........
I'll chain them to the axle and store them underneath. If I do need to move unexpected, I'll just be one day delayed getting these mounted on the rims.

Hummm..........I guess I was basing my thoughts on tires under pressure/load would degrade faster, than stored off the rim in shade. Oh well. Who knows. I really don't see me keeping this unit for another 7 years anyway. They tend to get pretty dated after 5 years. You can spot an old model a mile away...........probably will trade up for the latest and greatest by 2021.

Things I have read from a tire manufacturer is for maximum PSI when parked for the winter. I swear it was Goodyear on their RV info site.

With all respect, the clock is still ticking vis-a-vis the date code on the tires. If you defer your purchase for a year, the tires will be 1 year fresher when you first install and use them and, based on the tires ultimately requiring replacement based on age, will give you 1 more year of service as compared to purchasing them now.

Sure!

Why put new tires -now- on a trlr that's going to sit for a year?.:h

And the second question......our cars and trucks usually are driven.
The tires *wear out* long before they would *age out*.

However, *if* an owner was going to store his car or truck, the covers are a good plan for that also.
Sun exposure will (eventually) destroy tires no matter what kind of vehicle they are mounted on.

BTW - They *all* should be sprayed/wiped with 303 Protectant..;)

I too would not replace the tires until I was approaching the time I would be moving. It is recommended to replace tires after only 6-7 years due to age. Too expensive to be losing over 15% of your tire life setting out the first year or more.

I never cover my 5er tires. 6 yrs on them (XPS Ribs) and no sign of weather cracking.

Actually it's 110lbs. I would contact GY Tech Support.
