storing rv on gravel, is this bad for my tires?

I camp in muddy areas sometimes but I sure wouldn't store my RV in mud.

Storing a RV long term vs camping for short periods is apples vs pickles.

In the storage lot it's parked on gravel. When I go camping it's parked on gravel. No issues.

I park my class C on the type of door mats made out of used-tire strips. They allow for good drainage into the gravel base and provide tire on tire contact.

The Michelin Tire Guide says to use something under the tires so I do.
I use thin flexible cutting boards I get at Walmart. Easy to store and cheap to replace.

Use wood to keep the water off and tire covers to keep the sun off.

I park my utility trailer on treated wood also. Keeps the water off but still doesn't protect them from sunlight, etc.

IF your tires can't take gravel you would not be able to use MOST campgrounds and even a few RV parks. No reason gravel would harm any tire.

Mine have been sitting on gravel since 1998 with no issues.

I park my TT on 2x12 treated lumber and my drive is gravel.....not sure if it makes a difference but it's nice coming home and I'm level when I park....:B

I have stored our 96 Southwind, tag axle, on gravel for several years.
No problems with the tires. The gravel drains and keeps the tires from sitting in water.
I don't put anything between the tires and the gravel.
