My 15 year old white floor mat for my '14 had turned brown, a common enough occurrence these days. It also wasn't lying flat, due to some careless storage. So I laid it out on the black deck of my open trailer hoping that a day in the sun would flatten it out again. But in the flurry of the last few days before leaving for Bakersfield, I forgot about it. It lay there for fully nine days. In that time, we had sun, rain, wind, and snow with temps ranging from the 20s into the 60s. When I got back, I saw it still lying on the trailer. After a few self-administered swift kicks for forgetting to bring it in, I saw that not only was it now lying flat but it had turned snow white again on its top side! The underside was still that brownish tan. I'm not real good with a camera, so the photos don't show the contrast between the sides very well, but the underside is, definitely, still that usual dingy beige.
I don't what caused it; perhaps it was merely bleached in the sun, or maybe it was the combination of different weather and temps. Nor do I know if some of you with similarly browned mats or maybe even all white tires would like to try leaving them out. But for me, it was a happy accident.
I need a mat for my 14 but I can't ever decide white or black. I like the white but looks like it would get dirty fast like white carpet.
You missed Fools Day by a full two weeks -- surely you're screwing with us!
Nope; it really happened!
Lay those white tires out lets see what happens?
Those UV rays will do that....
Well, I've laid other things out in the sun and the results haven't been pretty. So maybe it was the combination of elements. All I know is, it was brown, now it's white, and I can put it back in the car where it will look good again.
You forgot to put the approved inner tubes under it! LOL
Well, all the humor and speculation aside, first one would have to wonder, as well as, determine if the mats are made of the same "rubber" as the tires. Then go from there. We're gonna know in about a month or so now that my "second generation" set of white tires are mounted with said approved tubes. I wish I'd have paid more attention to the previous tires, as these new ones sure look they've had something "painted" all over them. I'll post a pic here, you can decide. Even the tire installer dudes agreed.
Yeah, that's what I was talking about when gray tires looked like a gray coating over a white tire, but then the last white tires I handled looked like a white coating over a gray tire.
That's something I'm going to add to the record of variables when I get back into it this spring.
I had fully planned to buy four new whites, but I am gonna wait until we see what transpires with your new tires.
Just for curiousity, does your installer use irons or a machine?
My car has a black mat. I've wanted a white one, but been too cheap to buy it. Maybe I'll try putting my black mat outside for a while and see if it turns white.
Mr. Thrifty, you have competition !
I just received my 4 Non Skid Tidy Whities. I was a bit surprised that they did not seem to be as white as I expected. It also seems they are coated with something. Maybe it is the same stuff that RV has on his floor mat.
Anyone ever see how they make tires, and all the different layers involved, that are wrapped before molding and vulcanizing? That pic Tim posted makes me think the tires are cored with cheaper black rubber, and have an outer white layer of rubber put on then molded.
I dont own any white tires, nor studied any at all, but have been watching the tire browning issue since I have a 13 I want whites on in the future after its done (at least a year or 2 away). So, any of this is hypothetical.
So if these tires are cored with black rubber, and a thin outer white layer, is that part of the browning problem? Meaning the stuff in the black rubber is seeping through the white?
What suppliers are selling the coated tires??
Benjamin, the white tires from 20-30 years ago that stayed white were black on the inside, so I doubt that's the root cause of the problem.
R.V. can i bring my set of brown non skids over to set on your trailer for nine days to see if they change back to white again.
Walter, well, that tosses my hypothesis then. Unless the formula has changed as some said it has.
Tim, sure does looks painted to me also. Doubt it will go brown now, instead it will probably go grey or black as the paint wears off. Good for show cars not go cars. Rather than come up with a white rubber tyre that doesn't go brown, they've stopped making white rubber tyres.
Those Firestone smooth grey tyres were painted white tyres.
I doubt any tires were "painted" either gray or white, that would soon show when the tread was worn just a bit. Am I missing something? JMHO Dave
Dick F., I think you'll have that black mat out in the sun for quite a while! LOL.
Mike S., yeh, I had the same reaction the first set of whities I bought last year, maybe it's my imagination, but I'd almost (& I do mean almost) be willing to say these tires from the "new batch" seem to be just a fuzz whiter. Probly wishful thinking.
I put a black floor mat out this week and it also turned white. But by the end of the day it turned black again after the temperature got above 32 degrees.
RV - I see a side business in your future.
To answer your question, I got my tires (and tubes) from Universal Vintage Tires, in Hershey PA. The two companies that Ashley, from Lang's mentioned, were Lucas and Universal. They both offer the WTTB return policy, but she said one of the companies was easier to work with.
