I have aluminum wheels on my truck and when it gets cold out I loose most of the air in them but not in the summer and it is a real pain. Is there anything I can do to stop this? When I had a 75 blazer I had put some of that fix a flat stuff in them and it sealed them up good but I know that when you get new tires the tire shops hate that stuff and it is also very dangerous if it catches a spark,So is there something out there that will cure this problem without the problems?
