The pressure is higher in some tires than it had been previously. I check roughly the same time of day, the vehicle has been sitting in a garage out of direct sunlight and has not been driven prior to checking. I can't figure out why the pressure in 2 of the tires is going up each time. I think it is the same 2 tires each time also. 1970 Dodge d100/eventually going on a 77 D100 frame

I keep putting air in my husband's tires every night, and the next day it seems like they are leaking out some and I have to refill them. It happens to the same two tires each time, but I don't see a leak in them. Any ideas ? (I have no real idea what could be causing it ? )

Sometimes to an unsafe level. really? I don't see how but I have a open mind and love to learn new things. Is this going to be like the airplane on a treadmill thread?

They are at opposite corners. How would dragging brakes cause the air pressure to rise and stay that way? I get that the brakes would run at a hotter temperature but would it really cause the air pressure to go up several PSI every 2-3 weeks? I just noticed this in the last month or two. I've had the same tires for years and the same alloy wheels which I've had to get remounted due to leaks around the bead. Come to think of it both of the suspected tires were the ones that were remounted. One of those was remounted a couple years ago and I didn't notice an increase last year. I think the other was remounted last year. The strange thing is I've had this vehicle since Oct of 2001, have had 2 sets of tires during that time and never encountered this before. 1970 Dodge d100/eventually going on a 77 D100 frame

In practice, there is.
