This is a new one on me. I know that technology is getting more and more advanced along with the devices and instruments to measure it but what is tire indexing? I took my 94 LS430 w/sport suspension to my local mechanic and they told me that my tire index was over the lexus reccomended threshold, also called Road Force Variation Mesurement. I am currently running Dunlop P245/45R18 96V M+S SYP Sport 5000m tires which I purchased from the lexus dealership last year. The tires have been rotated/balanced every 5K miles. Now this has become an issue. Can anyone help to explain this to me. Thanks so much in advance, Dave
