Put a set on Halibrand mag wheels and they went flat real quick. Left front went flat in about 10 days. I called Finishline motorsports, said they had epoxyed the wheels to stop porosity. Went to local tire shop just to see for myself. Air was coming thru the sidewalls. Put a set of Avons on the mag wheels and no more leaks. Tires and wheels set in rack until I want to change the looks of the car. Have been setting in rack for 6 months pressure was down 2-3 lbs. Mag wheels were not the problem. Put the Goodyear slicks on another set of wheels and will air up as need be. I have Trigo wheels with billboards on car most of time. Goodyear Billboards will lose about 3 to 5 lbs in 6 months.
