Tires releasing chemicals

I mount golf cart and trailer tires 5 days a week in a warehouse. I don’t put them on vehicles I just mount all day so they can be shipped out. Now that it is 90+ degrees in the warehouse every time I walk in I start having a reaction to something in the air causing a lump and scratchy feeling in my throat all day long. Does anyone else also experience this? I’ve worked there 3 years and have never had this reaction. The only thing that has changed is a certain brand of tire from China comes with tire shine on it now making them really slick and a pain in the ass. Is the heat bringing out the chemicals in the tire shine?
