I have them but have not tried them out yet. I did hear that if you have tire pressure gauges in your wheels these could damage them. Has anyone heard that or have a problem with that. The F250 is the 1st vehicle I've had that has those gauges in the tire....
Thanks!
Are you referring to the TPMS system now in all vehicles? If so: No, airing down will not hurt them, it will just trigger the warning light on the dash.
