So I just upgraded from the stock 17" wheels on my '08 to some 20s about a week ago or so. Since, I've noticed that within 3-5 days the tire pressure seems to drop from the 37-38psi I have it set at down to about 31-33, especially the front ones. This morning before heading out I checked, only the fronts ones (i know i should've checked them all) and sure enough they were down at about 31-32 and I just put air on them no more then a few days ago. I went to the gas station on my way to school and the attendant there checked the pressure all around. He confirmed the pressure in the front I got, and said i had the rear passenger down at 20psi (since I didn't check it myself, i don't know if they checked it accurately or not..) so he went ahead and brought the pressures all up to 37/38. Aside from the rear passenger which i assume may have a potential leak, would anyone know if there is something going on with the other wheels/tires, the front one's especially? I plan to go to the tire shop where I got these later today to have them check it out...but if anyone could provide me some info before hand, i'd really appreciate it. I just hope it's not the worst case like I'm thinking (crack in the rim or faulty tires) thanks guys..

Oh wow, weird issue. It wouldn't surprise me that one wheel would do that but three is just totally weird! Don't wait any longer and take them back to the shop and have em looked at!

I have 20's, mine hold pressure better then my stock 18's did. Why are you trying to run 38 psi anyway? That is way to high. I run 31-32 as recommended by the tire company and Discount Tire Direct. I have Falken FK452 245/35/ZR-20's.

yea...you're actually the 2nd person 2 tell me that about running 31/32psi. my tires are also 245/35/20. it seems that the whole thing is nothing more then me being a bit paranoid...i think everything's ok

Recommended tire pressure by who? Not the tire manufacturer. I wouldn't run a low profile tire more than 10 PSI under maximum inflation, which is what most tire manufacturers suggest, better tire wear and lower rolling resistance.
