As far as I know, the issue with tires is when they are on a vehicle, and tiny particles are worn off as they are used on the road, which then wash away and create problems. If you rinse them off and give them a good scrub I think there would be little issue with pollution, both with the soil and the final crop.

The problem is that you have no idea whether it's done you harm or not. Tyres contain a number of carcinogens, do they get into your body through the spuds ? Does water collect in the tyre walls, leach out chemicals, and get sucked up the roots ? Who knows.

like I say, been using this method for 15 years without any adverse effects.
I only put about 5 potatoes in the bottom tyre, well away from the tyre walls, in a sort of diamond pattern, so nothing is touching the tyre itself.
