303 protectant on tires before or after Tire Wet?

"add on" stuff to tires are nothing more than snake oil junk, does nothing but make tires "shiny". Your trailer tires are not "boulevard queens" and do not need such treatments.

Many if not ALL tire treatments contain petroleum distillates which ARE harmful to rubber. Your tires come from the factory with ALL the needed "protectants" already built in and nothing you can plaster on the sides of them will help or give more life.

Tires ARE a "wear item", they have a finite life of 5-7 yrs of service and after that you are taking chances.

Heck I just took off tires a few years ago on a 100+ year old antique auto that were put on back in the 1950s'.. Yep, 60 yrs old and the only reason I had to take them off was the inner tubes had gotten weak and leaking. They NEVER had any tire "treatments"..

Save your money AND your labor and skip the greasy kid stuff..
