Hi guys,

I have a 21' Aspec SH-AWD. I've been noticing that about every two weeks, one of my rear tire pressures is about 3-4 PSI less than the other 3 tires. I currently have them set at 37 PSI, and the other day noticed the one tire at 33PSI. I did top it off, and it seems to be holding as of now. However, this isn't the first time I've had to top of the pressure in that tire. That being said, I do live in the Midwest, and the temperatures are all over the place this time of the year.

Is this normal for tires to drop pressure like this? My main concern is that it only seems to be that one tire. I am wondering if I have something in the tire, or I have a bad valve, or a bead seal leak. Has anyone else had a similar situation?

Would you recommend just continuing to watch the tire, or should I make the trip to a tire repair shop?

Thanks all!

 

You have a slow leak. Take it to a tire shop, not the dealer.

 

3-4 psi every 2 week is not normal, especially when its one tire only. Check to see if you have nail in it, it might be hard to find…. It could also be bad bead or valve leak.

 

Thanks, guys! I’m at the tire shop now, I will report back their findings.

 

Wonder what the problem was.

 

My guess is a screw hidden in the tread.

 

Yep, nail in the tire! All fixed now.
