Trailer Legs

According to Michelin Man. Most all tires are subject to flat spotting but it is not permanent. As the tires warm up the flat spot will go away, usually in 20 minutes again according to Michelin Man.

I looked up these "levelers".

Reminds me of the ANDERSEN levelers. I say no bueno to both.

Why do you want to do that? Modern tires are fine sitting for long periods.

No, they aren't!

Many tires today have cap plies made of nylon. Nylon is VERY prone to flatspotting - and the longer they sit, the more likely the flatspots may be permanent.

Can you please list a couple of these tires you are referring to? Also post a couple that do not apply.

I just saw these today. They have been out for years and never seen them. I was wondering if anyone has used these and what your thoughts are about them. They say they can be used to store your trailer with the wheels off the ground.I want to use them to lift my fiver. Www.trailerlegs.com

I've never used them, but that doesn't stop me from having opinions about them. ;)

On the face of it, they seem to be a pretty good solution for folks that want to get one or more tires clear of the ground - be it for storage, maintenance or to change a flat.
My real concern would be taking the unit down off the stands. Imagine the stress on the leaf springs of the entire camper bouncing down on all four wheels at the same time.
Considering that we almost universally believe the suspension under our campers is borderline safe, and we do see breakages of hangers, shackles and springs quite often, I am loathe to use anything that I think might add unnecessary stress to that system.

Everyone has a different idea of what "long term storage" is. Some people think that winter storage is long term. For me long term storage would most likely mean the tires should be replaced from old age before worrying about flat spots. Heck I have drug cars out of garages that sat on flat tires for 2 years. Air them up and roll them. Owner drove with no issues until the cars needed new tires from wear. Some tire brands will hold up better than others to this condition. If they were good years I would just replace them cause they live up to their name quite well. If they were Michelins it wont be an issue. Those things will rot away before you can damage them.

This is simply not true. The opposite actually. Modern tires are manufactured with materials that resist and rebound from flat spotting. I haven't heard about anyone complaining about flat spots in years, let alone on a TT or FW where it would be even more difficult to notice anyway. But define sitting for long periods. Years? Maybe. A few months? No.

Just dont see how these would help stabilize. You will lose the tire bounce but the springs are still going to move. I have a large dog that can get a trailer bouncing pretty good when he plays so I have an extra set of scissors jacks that put under the center of the trailer on the frame right in front of the front axle that takes a lot of that bounce out.

As far a long term storage goes just keep the tires out of dirt with a 2X12 under them and cover them for sun damage. Radial tires can sit for a long time and any flat spots will work they way out very quick as they warm up.

I think you're borrowing trouble. I either use my jacks to keep the tires off the ground or just park on boards. Sun and lack of use ages RV tires more than anything else. For the cost of these devices you could buy new tires which are going to age about the same rate whether they're on the ground or not.
