Our Yuma pop-up will

[linda16]

be sitting w/o use for 7-9 months. We are in Charleston, South Carolina area - its been a mild winter so far.  Should we move it around a bit so tires are not in same position for all that time?  It is parked in a tight space, is there a good way to spin a tire to a different position without having to hitch up ? Sould I change air pressure at all?
Thanks for any input.

A quick Google search yielded the following excerpt from the Yokohama tire web site:

=================================================

TIRES INSTALLED ON VEHICLES

Storage area should be level, well drained. Care should be taken to avoid prolonged contact with petroleum based substances: oils, fuels and asphalt.

Long term storage, or storage of seasonal vehicles; i.e. RV's, boat trailers and show cars requires special preparations. Vehicles should be raised on blocks, so weight is removed from the tires.

If blocking is not possible, tire pressure should be increased 25% from inflation required for the loaded vehicle. Vehicles should be moved every three months to prevent flat spotting and ozone cracking at the tire sidewall flex point. Flat spots usually disappear, when the tires warm-up, after a 25+ mile drive.

Flat spotting, which occurs on vehicles not moved for six, or more months may not disappear.

Tires on vehicles stored out-of-doors, should be protected by opaque covers to prevent damage from sunlight.


PRIOR TO RETURNING VEHICLES TO SERVICE

Tire pressure needs to be adjusted to required inflation before the vehicle is returned to service.


REPLACEMENT OF TIRES ON FREQUENTLY STORED VEHICLES

Owners of RV's, boat trailers, show cars etc. should have their tires inspected by a qualified tire dealer, if sidewall cracking and crazing occurs. Remaining tread wear is a poor gauge of tire serviceability on
these vehicles. Over time, the bonds between the rubber and reinforcing materials deteriorate, regardless of remaining tread.

Unserviceable tires should be scrapped, by cutting beads, or cutting
through sidewalls, to prevent re-use by unsuspecting persons.

===========================================

HTH.  I learned something, too.

the newbie ignorance, what is blocking?

The act of raising the popup/trailer to take the weight off of the tires.  Requires jack stands, or some way to support the camper, at the appropriate place on the frame.

If it were me and I was going through the effort to raise the trailer and then set it on blocks, I would probable take the tires off and store them out of the sun (Basement, garage).  Ozone is one of the biggest enemies of rubber.  Leaving the tires sit in the sun dries them out and makes the problem worse.  Don't ask me how I know that.  

Again, Hope That Helps.

Actually the 25% over does not apply to ST trailer tires. That's for P grade and LT grade tires on cars/trucks where the recommended inflation pressure is not the maximum recommended inflation pressure.Also you'll find adding a desiccant product to the trailer a good thing as well for long term storage. Thermo cycling (daytime heating/night time cooling) tends to draw moisture into the trailer and it doesn't leave. The desiccant keeps the interior dry.

I think from the above website the 25% is referring to trailer tires based on the qutoed info below

The statement above does say from inflation required for the loaded vehicle which would be the popup manufacturers recommendation not necessarily maximum inflation pressure though.
 
FWIW
The Goodyear site says to inflate 10 psi over maximum rated if you are driving above 65mph up to 75mph, this applies to Marathon Trailer Tires. It reminds you to make sure the wheels (rims) are rated for this extra pressure before doing so.

Except that search the Yokohama Data base shows no ST (special trailer) tires.

Their "trailer" tires as far as I could find are LT grade tires. Which quite a lot of heavier Towables do use.
25% on a 90 psi maximum 8 inch ST tire would be almost 22 PSI over it's 90 psi limit.
 
Tire advice is company specific when taken from the company's website.

My husband and I moved the tires to a new position and we have always had them on rubber mats. They have been sitting for past 3-4 mos with no sign of problems. We have to leave town again so I could not over-inflate tires. Stll not sure by how much given the different opinions.  We will deal with that if need be when we return.
Thanks again

What tire brand do you have, Linda?

[linda16]

They came with the pop-up. Its an 05'. The Yuma is parked/stored about a mile from our home. We are heading out of town tomorrow morning so won't be able to find out for awhile. Thanks for the interest.

Have a great trip.
I have two sons that live on John's Island and frequently work on Kiawah Island in the building construction trade. Small world, huh?

Anyone recommend a jack that the used for their campers?.   Right now my camper is inside the garage with tires still on. I have no way of moving it as it is right against the sidewall. How does storing the camper inside the garage different from storage it outside?
