i hear ya. My contis on my spec v are always losing air. The max psi on those tires is 51 psi. I usually fill mine up to 49 all around. I found that the best for both gas mileage and performance/comfort. I don't know what the recommended setting is,but i've tried everything form 44 to 51 and that was the best for me. Hope this helps.

Open your driver's side rear door and look at the door frame by the rear seat. There is a sticker there with the tire pressures, mine says 33 psi all around. 49 psi sounds quite high and with that much pressure it will probably cause the middle of the tread to wear out before the outsides.

SE-R here but I've got 51 PSI max Y-rated tires and when I got them from a major Michelin dealer they were balanced and filled to 41. The answer I got when I asked if this was a good number (as the inside door label specified 33 front and 30 rear) was "well, I wouldn't go past 46." ummmm....okay....

Nice superlight glide but we're talking spine-shaking ride here.

So for the last several days I've been assuming I had to get a gel-seat until I spoke to the tire dealer I should have bought from who said, no, just because it's a 51 tire is absolutely no reason to go past 40 and in fact his BMW's on 51 PSI Pilot Sport summers and not even considering comfort etc, he found he got the best handling and stability between 33 and 36. Meaning, though you definitely get gains in some areas by increasing PSI, you could be losing in others and that when it comes to a sporty car there's more to the manufacturer's recommendations than they get credit for. Sure you need to ignore door labels to get better handling on a hyandai, but we've got more, overall, going for us in the SE-R/Spec-V.

Stay between 35-40 for normal driving. The recommended 33 is a tad on the low side. And yes, they loose a little air over time, but not more than I would consider normal.

I was wondering the same thing. A Week after I picked up my car, I checked my tires and they were all over inflated if you go by the decal in the door jamb. I decided to run 33psi like it said. I talked to a couple of mechanics and they said to fill it up to max pressure. No way was I going to do that so I started filling them up to about 35psi. Didn't like that too much so now I have the fronts at 35psi and the rears at 32psi.
A week or so after I got my Spec V, I noticed one of my front tires kept losing air, so I called the dealer and he said it had a pin hole in the side wall. They replaced tire no problem after waiting almost 3 weeks for them to get one. I was so paranoid about the pressure I used to check it everyday.

Damn with that pressure... you'll wear out tires really quick...

the car says 33 I believe.. check the sticker on the drivers side door or driver's side passenger area over the wheel well, the sticker tells you what to use..

Remember tire pressures can vary drastically depending on how hot it is and how hard you are driving.. I've seen a difference in 5 psi even after my tires were warmed up, and my warm pressure is usually about 2-4 psi above the cold pressure...

Adding more air might let you hit corners harder.. but your traction will not be as good (I found about 32/33 in the rear and about 35 in the fronts was a good combo for sticking in the corners around here.. I went higher and I lost traction sooner allthough it felt like the tire didn't flex as much..

I hope that 51 psi was on some FUBAR gague... I found my gage to be standardized, but I've seen some gas stations gagues on the pump to be out as much as 5-8 psi..

DO NOT INFLATE YOUR TIRES TO 51 PSI

If you like driving on ice then 51psi should be just about right for you. There will be NO sidewall roll. Some is good. None and too much are bad.

I don't know anything about drag racing but I think I've seen 26 to 28 in the front and 38 ish in the rear. If you are autoxing, start wth 40 front and 38 rear. Chalk your tires and see where they roll to. As the day and tires warm, you may hav eto readjust. 45 front and 42 rear is as far as you need to go. If you are track racing maybe a pound or two more. If you are grocery shopping and like the occasional curve in the road, go with 36 all the way around. If you are picking up Granny for Bingo Nite, go with 33.

But 51psi is NOT comfortable nor is it safe especially in the rain. If you insist on running at 51 psi please stay away from me. I don't want you hitting my car.

mutt,
If you were at 20psi you should have been able to see the tire was low. I'd check for nails if I were you.

Some say the tires leak, I don't think I believe that. I've never had tires leak unless there was a nailin them. And I've bought some pretty cheap tires in my day. I try to make it to at least one autox a month so I inflate to 40, run and deflate to 36. SO I couldn't tell if my tires will hold air fro 6 months without chaning.

All,
Your tire pressures can easily change 5+ psi from sitting in the driveway in the morning to checking after getting to work. Add a hot summer afternoon and autox or better yet track time and I wouldn't be surprised to see 10 pis or more difference.
