Changing a tube today, as one does, and stopped to read the box. What is the reason for something like lead? Do all tires and tunes have it, or can I just make it a point to avoid one or two manufacturers?

No clue. But litterally everything is know to the state of California to cause cancer. I personally wouldn’t worry about it.
Washing your hands afterwards is probably know to the state of California to cause cancer.
Valve stems and parts are commonly made with brass. Many brass alloys include lead.
The valve stems are made of brass or bronze, which frequently contains trace amounts of lead.
It’s probably because it’s made with petroleum, lots of rubber products are petroleum products and petroleum products are linked to cancer.
It’s cheaper for the company to print this warning, than it is to test for the HUGE list of chemicals that’s on the State’s list. This law had great intentions, but it just isn’t practical the way it’s written.
It doesn’t say it will expose you to lead,per se, but chemicals known to blah blah blah (and this may include lead or it may not). Legal mumbo jumbo for CA proposition 65. This warning is on just about everything which results in most people ignoring it altogether. Obviously not “everything” but it sure as hell feels like it.
Since they don’t want different packages/sku’s for CA vs everywhere else, they just slap that on regardless of state.
In order to avoid putting a Prop 65 warning on ANY product, the manufacturer must prove to the State of California that the product DOES NOT contain any carcinogens. Instead of paying for the rigorous testing, many manufacturers opt to just put a Prop 65 warning label on their products instead.
Don’t ride in California and you’re fine.
Lots of stuff have lead including meat and seafood, California is the worst
Lead was historically added to rubber, particularly in tire manufacturing, because it acted as a vulcanizing agent, helping to improve the rubber’s elasticity and overall durability during the manufacturing process; however, due to its toxicity, lead is no longer used in most modern rubber production and has been replaced by safer alternatives like zinc oxide.
