Tires slowly lose air - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

trcsr · 12-09-2015, 08:21 PM

2013 RS with the 8" front wheels and 9" rear. Since I first got the car it did lose a little air over time. I has Perelli tires. Last April, when I exchanged the wheels with LA Tire and Wheels for chromed factory wheels. Since then the slow air leak has increased. I can set the TP to 35 psi and around two weeks later, whether or not it has been driven or just sitting, it will be down to 32 or 33. This has happened during warm weather or cool, so temperature is not a factor. It happens with all four wheels, so it doesn't seem like it would be from a blemish on the rim or a bad seal on the valve stem. I have a minivan with Continental tires and an F150 with Michelins and never have had a similar problem. The only thing I can think of is that it is a characteristic of the Perelli tires. Any other ideas? Has anybody else had a similar problem? The car now has 16K miles on it. I am not real happy with the Perelli tires, but don't want to replace them with only that low mileage, but am really impressed with the Continental tires on my van. Thanks for any input.

I notice the same thing with my 2015 rs, i fill them up to 36 and a couple days maybe a week later i look and they are at 33. I havent seen them go below 32 but it still concerns me

My 2ss does the same thing but it all depends on how hard u drive and air temperature out side plays a huge roll

Putting air in them while they are cold?

My 14,RS does the same thing. I have 2 sets of wheels and tires and I lose pressure in all of them. Drives me crazy.

Have never had any issues with my P Zeros. As expected, when the weather turns cold I have to add a few pounds. When it warms up I have to let a few out. No problem.

snarky · 12-10-2015, 05:31 AM

My G2's have a range of 28 (cold mornings or after sitting extended periods) and 37 driven in blazing summer. I always use the factory recommend psi of 32 square. My right front usually loses a pound or two vs the others.

xnuyokr · 12-10-2015, 06:36 AM

A few pounds either way is normal. I see it fluctuate all the time depending on the temperature. Just fill a pound or two over recommended so it doesn't drop low.

Jalberdi99 · 12-10-2015, 07:47 AM

same problem here, 2 front are ok , driver back looses a lot of air (fill with 37, 2 weeks later it might be at 34) back passenger not as bad as driver back tier. i took it to the dealer ,but they couldn't find anything wrong with it. i even tighten the stem valve thing on all 4 and still losing air. it's been happening since day 1 (about a year)

The low profile tires have less air in them so any variation in pressure is going be much more noticeable that in a larger tire.

Mine do the same thing. My G2's will vary as much as 4 to 5 psi from cold to warm.

It's normal.
