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..

303 is not a greasy kid stuff, but Tire Wet is :). 303 is a UV protectant. Though, I'm not using it on my tires - wheel covers work same well (or better). A piece of cardboard strapped with a bungee cord is all you need (and you only need it in summer and on South side). Or get a vinyl cover for $20.

303 protectant on tires before or after Tire Wet?

I use only Dawn Dish soap on my tires.

Oh Shame On Me!

I had been using silicone with great success since introduction in the 60s. In 1990 I switched to anhydrous lanolin. Sheep grease.

While 303 is water-based, just because it appears to have "washed" off it is still providing UV protection. I apply it about once a month or once before I put the tire covers on if we are sitting for a month or two.

I recommend 303 because I have my reasons. I've been using it since Y2K.
I agree, everyone can do whatever they want.

I'm an organic chemist by trade, and I only avoid tire shine products that are silicone-based. I also choose to use products that include UV protection. Can't hurt out here in the Southwest, where higher ozone levels in the air mean shorter tire life. You of course can believe whatever snake oil salesman you like, LOL.

Shiny tires are tacky. Clean them then use 303 to protect them.

Agree especially on a trailer. And it will only attract dirt/grime. Just use the 303 as it will darken the rubber and protect it (without the cheesy wet/greasy look)

I like nice looking tires so 303 is what I do. I kinda wonder if the guys that think snake oil wax their trucks and cars. Not needed for paint so why wax? of course I believe it is yours and do what ever you feel like doing .

Never use any petroleum product on tires. 303 is okay to use.

Have used 303 for years on all rubber products. It is a UV protector.

I will agree that covering the tires is the best protection, but it does not work well when driving. :B
UV is present year round, not just in summer.
I have been using 303 since 1986. Still in the testing stage, so far so good.
