last week i put on a new set of american racing shelby torque thrust wheels with nitto 555's. incredible difference in latteral grip from our factory offerings. i bought some tpms sensors and was going to make a pipe bomb and stick it in the trunk to satisfiy the onboard tpms sensor, and i havn't done this yet. so far i have not had any tpms warning light to come on. i know the warning light works as i had a flat once on one of my stock tires before changing over to this new set up and the light came on then. anybody else changed out wheels/tires on your bullitt? any warning light issues? i find that i am slightly perturbed that i spent $71.00 on these tpms sensors and apparently i don't need them. based on my experience, i would reccomend that if you are going to change out your wheels/tires to wait and see how your computer will respond before you purchase these new sensors.
