Was in early afternoon. Full sun in my backyard near Akron, OH. All temps except the one of the tire with the cover off were recorded in less than 5 min time frame. As I said in post after taking temp of the tire just after removing the cover I waited about 30 min and then got the high temp.
Numbers are real. I do not sell covers, do not work for and never worked for a cover manufacturer or company that sells covers.
The later post where I used a black plastic bag over a tire to simulate a black cover I waited about 1/2 hour with the bag over the cover. Got temp of the bag then removed the bag and got temp of the tire.
Since you and others seem to have some concern about the test, I plan on doing a time temp test in a week or so (I misplaced my IR temp gauge so have to find that first)
I have no budget to go out and buy a set of black covers as I would have no use for them and wouldn't even give them to someone else to use, so I will be using a sheet of black plastic to simulate a black cover.
I have noted on a trip on US 30 which is East/West road I could see a temp difference of over 10F using my internal air chamber mounted TPMS of sun side vs no sun side on the RV even when driving.
Driving temps are more complex due to air movement and heat transfer rates due to higher temperature differentials.
Hope this helps clear things up.
