Not wanting to spend another $900 for a new set of tires.
If you have a 4WD then yes, this is technically true. The difference in the rolling circumference of the new tire compared to the old tires can cause increased wear in the transfercase as well as cause the traction control system to act up, as it senses one tire as spinning at a different rate than the others.
People all have their own idea of how close a rolling diameter is close enough to prevent damage. There is no formal tolerance published that is "close enough", that I am aware of.
Personally, I would rather pay the money and get all new tires than risk damaging a component that costs much more than $900...but others may advise differently.
What is wrong with the tire that can not be repaired? Damage to the sidewall?
