The theory is the steel belts in the tyres heat from microwaves. We saw canvas belted tyres in the California fires didn’t burn next to steel belted ones.
I was thinking it might be aluminum wheels v. steel wheels, but that's certainly a solid theory worth digging into. It could even be a combination of both. At the least, it would be an interesting dig to get some statistics on.
