He is right your odometer is going to be off now too.
I would just keep an eye on the pis and if you got to keep filling them every day or two you need to take the tire off to clean them. Mix some soap and water in to a spray bottle and spray it on the bead. If you see bubbles your in trouble. Mabby take it back to the place that put them on. You need a tire machen to brake the bead down. Then use and angle grinder with a sanding disc in it to clean the rust up.
