Winter Tire Maintenance

If this was my TT, I would raise and block the trailer so there was NO weight on the tires. I would apply a liberal amount of 303 to both sides of each tire and let it soak in for 24+ hours. I would then reduce the pressure in each tire down to 10 PSI. and cover them. With the reduced air pressure and no weight on the tires, exiting crack will not expand and new cracks will not develop as the tires heat and cool with the air temp. With no weight on the tires, the tire cords will not stretch and no flat spots develop (the 10 PSI will help keep the tires round).

If I were really, really ambitious and knew the trailer would not be used for more than 6 months, I would take the mounted tires off the trailer and store them out of direct sun light in an unheated garage after the above treatment.

Tires which are not used on a regular basis will dry rot!

This can happen in as little as 4 years. When used on a regular basis, heat builds up and chemicals within the tire wall work to the surface and help protect the tire. It sounds crazy but you can do some google searches and find more detailed information. The dry rot killed my spare tire stored under the bed of my pickup. After 4 years I put it in use. It looked good initially but cracks formed with just a few hundred miles of driving.

An RV tire cover will not prevent this. It is likely that Aerospace 303 will but it requires thoroughly cleaning the tire and then spraying a good coat on both sides of the tire. If exposed to rain and the elements the tires need to be retreated about every 3 months.

when outdoors,cover the tires ,the sun will eat them.

Pump up to max pressure and put a vapor barrier between the tires and concrete

Same issue, different location. I will be storing the 5th wheel in Charlotte County, FL, new to me this year and am welcoming advice for tire health. Will the tires age quicker in this warm climate?

I,m in north east ohio have a small C in a bildg on nice days when the salts not on the roads I drive the mh about ten miles if a tt I,d jack it up .if outside I,d cover the tires .

Number 4, sell the tires in the spring and install made in USA tires. :D

Then do number 3 in the future.

Number 3 is the best option. Tires do best when rolled/flexed. It will help for longer life, and reduce the tendency to crack/weather check. While raising tires for storage may help, IMO, not worth the trouble for an RV trailer.
