Petroleum Distillates not good for tires?

[04ShadowShaker]

There was an article on another forum related to a tech session about tires at the Portland Porsche Parade... there were four panelists - tech reps from Michelin, Toyo, Pirelli, and Yokohama. A very interesting topic came up during a discussion about how long - in time, not tread life - today's tires actually last. All the reps recommended replacing your tires after a maximum of five years, no matter how much tread is still on them. But they also said your tires will last longer without cracking on the outside side-walls by NOT using any tire dressing product that contains any sort of silicon or petroleum distillates to make them look better cosmetically. All said that they put what they called anti-ozoneates along with some wax compounds too, into the rubber compounds for the tires to combat the effects of ozone in the air so prevalent now days. If you use tire dressings with these ingredients, it doesn't allow the anti-ozoneates to come to the surface and your tires will crack prematurely.

I am a long time user of Endurance High Gloss but could not discover whether the ingredients in the product are what was mentioned. Does anyone know if Meguiar's tire products are bad for the rubber?

Hmmm...

I've used the same Endurance High Gloss on my Dad's Expedition for three years - atleast every month. I have yet to see any cracking or deterioration. Personally, I've seen more tires without dressing crack than tires with dressing crack.

It's late, we have to get up early and buff out a couple of cars tomorrow...

Suffice to say, Meguiar's would never make a tire dressing that could affect a tire in a negative manner, we would do that to the safety of you or your family.

Just to note, there are all kinds of "Petroleum Distillates", for example my lips are a little chapped as we live in the desert and it's kind of dry around here, to help with the problem we're going to use some Chap Stick brand lip balm which is made from 44% Petrolatums




Sometimes you just have to put your trust in the name on the bottle.

The only way to wreck a tyre using petroleum distillates is to absolutely soak the tyre in it lol I was a tyre fitter for 3 years. Cracking is usually caused through natural aging of the tyre, the rubber loses its flexibility and hardens, then the walls begin to crack. Hope this helps a bit!

With both replies. Potentially if the tire was soaked then in the long term I could see damage being done to the sidewall. I have a hard time believing that megs would sell a product that with normal use would damage any part of your car. So I will just continue with the name I trust, and let thier chemist figure out that stuff.
