Do TPMS's....
Yeah 38 psi is pretty high. I'd spend $150 on an AEV ProCal (or find one used) and use it to set your TMPS to whatever pressure you want it to warn you at. Personally, I set mine to 0 so when I air down to 8-10 during wheeling trips, I don't have to look at that stupid light.
Anywhere new you're going to pay retail ($150) for it. But you can usually find them 2nd hand on forums for about $100. Just make sure the seller has set his/her vehicle back to stock; otherwise the ProCal won't work because it'll only work for one VIN at a time. Once you use it, it registers/locks to that VIN and won't unlock until that vehicle is set back to stock settings.
