Thanks for the additional info! Now I understand. The valve stem type I could understand but the "strap on" type was unclear.

 

I'm not sure which tire it is. All four were about the same, all slightly low.

 

I've been carrying a can of fix-a-flat for years (refreshed with an new can at intervals) but never have used it yet. I also carry a pump which I've used a few times over the years. A good, up-to-pressure, spare tire has always been enough to get me home -- so far..

 

I've used both fix-a-flat and green slime and both of them screwed up the wheels that I used it on. They both corroded the rim, not making it unusable, but if I had to go sell it, they'd think I acid washed them or something. I should've taken pictures and sent it each company, but since they weren't my rims, I could care less.

So I can only imagine what it might do to an electronic sensor. IIRC, a while back my Ford service center told me no way on those quick fixes.

Either a tire plug, use the spare, or have it towed.

 

So, you've used this stuff at least twice? I've never been in a situation to use it -- not yet.

I carry the can of fix-a-flat for that one time when my spare is no good and I'm out of cellphone range. In this (admittedly remote) possibility, I won't care much if my wheel is screwed up after I get back to civilization. Although I doubt if the cheap wheels on my XL would get damaged much. BTW, I don't carry a tire plugger kit in my truck. I do carry one on my motorcycle. Motorcycle has no spare.

I have to put this out there: I've been using fix-a-flat for 30+ years to blow up my wheelbarrow tires, getting it all over the wheel sometimes. It has never screwed up those cheap wheelbarrow wheels. When the wheelbarrow tire won't hold fix-a-flat air anymore, it's time for a new wheelbarrow tire. Sometimes it's time for a new wheelbarrow.

 

Yes, not on any of my vehicles though. I used to carry it with me. Now I don't.

I used each one on aluminum wheels and both got pitted/turned whitish color. One was on an American Racing rim and one was on a clad-alum rim on an Exploder. Both got severely pitted/etched.

The XL rims are steel rims with covers. You can actually change the covers and get chrome ones if you've got the grey-steel colored rims. They sell them on eBay. Now I'm not sure what it would to them. I'm just saying with aluminum rims they get pitted from the stuff, at least from my experiences with two different products.

 

Thanks for the suggestion but putting chrome covers on the wheels of my XL would be like putting lipstick on a pig. Well, maybe a pig is better looking than my truck. My XL is basically a work truck -- even though I'm retired.
