Tire experts

Am getting ready to head out on extended camping /RV trip. But, have a GMC Safari AWD van at the house that will be left sitting for a couple months. It's got pretty good tires on it, but I wonder if I should put it up on blocks to keep the tires "off-weight" ... or should I have my son move it every week or so just to roll the tires ... he can't drive it around because no plates.

SO couple things -- one should the tires be off-weight, or rolled. Also, related to that, should I just have him 'run the engine' and circulate the fluids every week or two, and at the same time, roll it around in the driveway so the tires change position ... don't know which of these help or are necessary. This van is a "pet" had it long time (180,000+ miles) and it still looks and runs great when I use it, I don't quite trust it for long-range trips anymore.

We leave our extra car, a 2002 Chrysler PT Cruiser, parked when we are on the road. It sits in the garage and is not touched. Never had a problem while we were gone and it never failed to start and run fine when we got home. I don't see it any different than when I put the motorhome in storage for a couple of months. When I store the motorhome I leave the airbags full and don't even put the leveling jacks down.

Just wondering if laying flat on the bottom does anything to the tires, mostly. They're pretty new and I want to get the miles out of them eventually -- but don't want to do something stupid, like later some tire guru says -- "ooh Monkey, all you had to do was roll them ten feet once a month, so they don't rot the bottoms" .... see what I mean, something simple might save them from damage. But I don't know the "something simples" ... M44

Excerpt from Goodyear tire maintenance recommendations.

STORING YOUR VEHICLE WITHOUT REMOVING THE TIRES
Ideally, a vehicle in storage should be placed on blocks to remove all weight from the tires. If the vehicle cannot be put on blocks, follow these steps for tire protection:

Completely unload the vehicle so that minimum weight will be placed on the tires
Inflate tires to recommended operating pressure plus 25%. Ensure that the rim manufacturer’s inflation capacity is not exceeded
Be sure the storage surface is firm, clean, well drained and reasonably level
Avoid moving the vehicle during extremely cold weather
Move the vehicle at least every three months to prevent ozone cracking in the tire bulge area, as well as “flat-spotting” from the prolonged strain of sidewall and tread deflection
Adjust inflation before putting the vehicle back into service.

Thanks FE -- won't be three months, so i'll do this and leave it sitting 'over-inflated' -- if my son gets needing something to do, he can let the air out and drive it a bit ...then do it again -- but most likely it will sit for the two months or so - tires UP ...

For only two months there shouldn't be any problem. I have left mine longer with no prep. Last winter I did dissconect the + battery cable. In you area I hope it is parked inside, where I live it don't make that difference.
