hey guys,

so i have some 195/45/15 on a 9 inch wide wheel

i put 2 wheels on the rear of my car, went to go for a test drive, went down my drive way it started leaking air... so i immediately drove it back up into the drive way, within 5 minutes the tire was completely flat, this is both tires... does anyone know what the problem is? need more seals? broken bead? i dont know, someone who has encountered this problem and have any input would help, and any place you recommend to remount these wheels would help, preferably a place that doesn't say "oh its leaking cause its the wrong size tyre, so we cant help you"

thanks in advance, tom
