Will Storing Trailer on Grass/Dirt Damage Trailer Tires

Updated 11/10/2025 | Published 10/21/2025

Question:

Hello, When storing a parked camping trailer outside, does it harm the trailer tires to be standing on sand or a grass lawn? Or, is it better for the trailer tires to be parked on cement patio blocks? If it is better for the tires to be standing on cement, why is that? Thank you so much.

Hey Ron! If you keep your trailer parked on dirt/grass for a prolonged period of time it can damage the tires. The ground tends to have moisture which can be absorbed by the tires leading to dry rot. More than likely you will also be on uneven ground which can cause the tires to deform and fail. Occasionally you can run into a soil composition that causes the tires to degrade as well.

Keeping the tires on blocks helps prevent these issues, especially the moisture. Personally, I use the Andersen Camper Leveler # AN68VR under my tires for storage. Since they're curved it helps the tire retain its shape so you don't get flat spots. These also help with leveling and act as a moisture barrier. This kit is enough for one axle so if you have a tandem axle trailer you will need to order two.

What kind of trailer do you have?

Hi Robin, Thank you very much for your helpful reply, including the link to the leveler. We have a single-axle A-frame pop-up camper trailer. Thank you again! Ron

Hi again, Robin, Regarding keeping the tires from getting flat spots: I'm in Minnesota and the trailer will be sitting outside for months during the winter and colder spring and fall months--maybe at least 6 months(!!). Would chocks be sufficient for keeping the tires from getting flat spots, or should the trailer be put up on cinder blocks or something so that the tires don't touch the ground? Thank you kindly. Ron

@RonV I would do something to keep them off the ground for sure, better to be safe. Some simple 12" x 12" pavers will do the trick and should be super cheap from your local hardware store.
