Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose).
I can not find anywhere on the Ford info in the repair guides the allowable tolerance. I know from going to all the Ford schools though. You measure the tire circumference with the car off the ground using a nylon tape measure. Comparing all 4 tires the max difference from smallest tire to largest one is 1/4 inch.
Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris
You are welcome
