thought i would post this, i am an avid michelin fan, bought an 02 ls with 88k with primacy mxv4 h rated. they were five years old and noticed spider cracking but drove 25k on them and the right front is really getting bad. i didnt want to spend the money on the other front or other 2 so replaced one right front with the left having 25% life left.. i for the record never had done this becaause i am particular and dont like pulling etc.. with money being an issue put one on front right and have to say amazing results. the car is riding alot better, absorbing road imperfections much better, not that this should be that surprising. but when i got the car i was thinking it rides a little rough but i am starting to think what the experts say after about 5 or 6 years the rubber gets rough and loses some of its absorbency...
just thought i would post for everyone to read
safe driving to all

 

Tires are the cushion between you and the road... there is no substitute for great tires... and when they get old you can feel it. Problem usually is it does not happen over night. So the subtle change over time is hard to notice...except when you put 4 new tires on.... then it's aahhhh, so that's how it's supposed to ride.
