This is probably a stupid question and something I should have addressed sooner than now.

One of my tires leaks about 10psi every week.

I still have the stock tires, and I'm at 22,000 miles.

So here's the dumb question: what could be causing this? I'm guessing it's time to change my set of tires?

Thanks!

You just have a slow leak in one of your tires. It was probably punctured by some road debris, and has been slowly leaking since. You can have a tire place patch it for around $30, depending on where the puncture is, but you lose the tire's speed rating.

If it can't be repaired, you'll probably need to buy a new set of tires, given how much they're worn.

22k miles on a stock set is pretty impressive. Mine made it to 9k. Id say you probly have a puncture. Get some new tires.

I agree with everyone else, get some new tires. However, if you really want to find the problem, air up the tire, put 8" of water in your bathtub, and v-e-r-y slowly rotate the tire while a small section is submerged. You will likely find the leak.

Or it could be a bent rim. I have had this happen on several cars. The rim may be bent on the inside where you cannot see it.

Leaking valve stem.

Thats better than me. My stock all seasons leak every other day. I've had the same puncture fixed twice already and its leaking again. I have Blizzaks on the way so no issues. My stock all seasons lasted 17,000 miles. Hard runs in the mountains and coilovers just weared the tires down. If you were to replace, Dunlop Direzzas are the way to go especially since you live in Hollywood.

sometime dirt can get between the tire and the rim. Or the valve is not closing enough. Try to make sure, not one of those problems first. And you might can save some money.

Oh and I forgot to mention this has been going on for about 1.5 months now.

I'll just go pick up a new set of tires...I'm pretty sure I'm due.

You may want to mention that one is leaking to whoever you have mount your new tires so they can determine what was causing the leak for certain. As others have said, it could also be a bent wheel or defective valve stem. You'd want to know that before throwing on a new set of tires.

ALRIGHT GUYS! Went in for service today at the dealer, and asked them to check it out.

4 nails.

Getting new tires this week.

These soft-compound tires seem to pick up everything from the road. I pulled off my Z1 *Specs for the winter and found 2 staples embedded in a tire blunt side first. How that happened I have no idea. I guess they were hot at the time and it just sunk in, who knows.

I only have those Z1s because I got a giant bolt in my OEMs at 3,000 miles. Ugh.

Good to hear you got it figured out, though. 4 nails is quite a few for 1 tire.
