Sorry if there's already a thread for this, I checked everywhere with the search function but I can't seem to find out. Apparently, my tired are under inflated. I have aftermarket rims that came with the car when I bought it used, so I don't have access to any info either from the makers of the rims (Cobra y2k rims) or Ford because Ford only gives infor about 14-17 inch rims on my vehicle model when my rims are 18 inch. By the way, the car is a 1999 GT.

I'll update with tire size cuz I just got home and I need to sleep. 23:00...

I know I probably need to get an alignment and rotation, too but I'd still like to get the tire pressure dead on.

Thanks for any help, guys.
