Put the new tires & rims on this weekend. 33 x 12.5 on 15s. No lift or any other mods at this time. Now my passenger seatbelt warning light will come on with one single "ding". Weird, and it may not have anything to do with the new setup, but it was not doing it before.

 

Try putting the cooler on the back seat !!

 

yea, there is no "passenger side seatbelt light" the light you MAY be refering to is prob the air bag light.....

 

Slide the passenger seat all the way back to see if the light goes off. The seat has a sensor under it and turns the passenger airbag off if it senses someone in the seat who has the seat really close to the dash.
