Spare Tire Specs Question......

chris22104 · 05-05-2009, 07:30 PM

Does anyone know the specs for the stock firestone spare tire? Max mph? Max distance of drivability? The combo only weighs 13 lbs, and says to inflate to 60psi. I have 3 new rims/tires, and was considering picking up a fourth, just for a one time, steady 55mph, straight line, warmed up, controlled 20-40 mile distance/mpg test.....then the exact same trip, temp, etc with the stock wheels. hmmm..... besides the obvious safety concerns, any thoughts?

i think that spare tire is rated at 55 MPH. you should be more than good for 20-40 mile trip. let us know your test numbers
