How to prevent dry rot on trailer tires that will sit for months?

Westleys works great. Used it for 30 years on WW and RWL tires. Gotta be careful it will damage and corrode clear coated and alloy wheels and etch glass.
I have used it to get bad staining out of chalked out white imron paint like greasy finger prints and oil splatter, but it will remove the paint if used to heavily.

 

Put the trailer on blocks, take the wheels off, spray with tire shine, wrap them in plastic bags and store in a cold area.

PS: on a serious note.. I'd worry about wheel seals deteriorate and start leaking more than the rubber tires getting "dry rot")

 

In Arizona they will dry rot very quick in the hot sun

 

You could always park it up here and let me haul some loads with it to keep it limbered up… lololol

 

Yep, I'd better rent it, instead of it sitting for almost a year.

 

I would not put engine oil on the tires just from reading this but you could find a rubber safe product.

It'll be ok. Seasonal use trailers since for months at a time on a regular basis. Obviously if you can find a parking area with shade it will be better so even park it east and west so the sun doesn't bake then directly it would be a good idea. As Goga posted leaking wheel seals seem to be a bigger pita with sitting trailers than tires in my experience .
