Tire Leakage

[connerd2002]

I have the 20x9 premium wheels with the all weather 265/35/R20 tires and they are losing pressure. Has anyone else had this issue? I lost 10 pounds in 2 weeks.

Valves aren't leaking? Done the spit test?

Are all of the tires losing pressure? how much has the outside temperature dropped in the past 2 weeks?

Yes, how many tires are losing pressure?

Northern CA. I checked Madera's weather. The daily highs have seen a drop of 30 F in the last two weeks.

If all four tires are down, I suspect it's the drop in temperature. Thirty degrees is a pretty good swing.

Yes they all lost 10 pounds, and the weather has drop in temp 30 degrees.

you will lose quite a bit of pressure with that temperature drop... add some air... when it warms up, you may need to remove some...

I had the dealer use Nitrogen in mine.
Although had to still add about 3-4 psi to each tire. Since then it's been good.
Cold it'll sit at 29, but warmed up from driving 31-32 psi.

Try moving the valve stem around. Mine had the same issue but I could only hear the air come out after pushing it side to side.
You may also want to check that the internal valve is tight. You will need a special tool for that. Looks like this.

I have one slow leaker as well. Will drop about 4lbs every 3 weeks or so. I have a valve stem kit so that's first on my list. TBH I'm nervous about letting anyone touch it. Pinch welds etc...

Sounds reasonable given that temperature change. You'll always need to add air when it gets cold.

Thank you

That's what the spit test is for. A drop of spit where the valve screws in will reveal leakage.

Two observations:
Number one: the tire pressure has probably been rather stable since the initial drop in pressure.
Number two: if the temps in your area will drop further this winter, you will have to add air again and in the spring remove air.
Number three: (I know I said two) Is this your first car?

Adjusting tire pressure in the Northeast is like a part-time job. Glenn

Have you owned a bike? They're so pressure sensitive I checked tyres before every ride after I stopped commuting on them.
