My 2006 Lexus GS 300 AWD was hit in the parking lot. Among other damage, one tire needed to be replaced. The other party’s insurance company wants to charge me $100 pro-rated cost for a new tire (with 10/32 tread depth) because the old tire was at 4/32 tread life.
Ok, I get the idea behind the pro-rated cost. The insurance company claims their obligation is to make me “whole”, and whole is a 4/32 tread tire. I’m arguing with them that they are causing me a problem by providing a replacement tire with significantly different tread depth. Leaving me with mismatched tires that could affect wear on my drivetrain and cause handling issues. I have read a lot of recommendations to replace all four tires, but can find nothing specific in my owner’s manual to support this.
Can anybody point to authoritative evidence that I should also replace the other three tires? Or that all four tires should be within some range of tread depth? Then I will negotiate with the insurance adjuster accordingly.
