2nd gen IS250 (2008), RWD Front tire is 225/40-18, Rear tire is 255/40-18. The rear last about 60k miles which is good, the front only 30k (factory, 150 UTQG) to 45k (Kumho LX Platinum, 600 UTQG). I've already done a zero toe alignment (the only adjustable setting on this car) on the front at a tuner shop, and the car is still the front wearing faster than I want it to. I am going to buy a new set of front again and am wondering what should I buy this time around. Should I: 1) Buy the longest trend life warranty (which usually correlate to a longer life), like Kumho LX Platinum, again at around $120-140 ea? My "concern" is these tires sacrifice fuel economy for durability. Traction of the LX Platinum seems to be good enough, but fuel economy seems to take a hit (around 1 mpg, 29 instead of 30mpg now). I don't think I will get to use these warranty because of the toe out wear that comes with the car, but usually if they have longer warranty they can last longer. My choice right now is any reputable tire that has >45k warranty for less than $130 shipped. 2) Buy the tallest trend block tire (i.e. 10.5/32" instead of the 9.5/32" to the standard 10/32"), because there are more meat to wear out in a "misaligned from factory" car. They seem to be about $120-145 each. 3) Buy the cheapest tire and just replace them often. I see Milestar MS932 being very cheap ($75 shipped) for a long warranty, but not sure how long it would last or how loud it would be. Not racing this car so it should be good enough for handling and braking. 4) Mount the tires inside out mid way, but there are so many tires being asymmetrical I don't think it is worth the effort or risk if it gets into an accident and legal liability for mounting the wrong way. (I found a mom and pop that will do it without paperwork) Flipping cost about $20 each wheel. 5) buy those fuel efficient tires and call it a day, saving money elsewhere in fuel. Which route should I take? I don't care about Summer vs all season. Any V or above rated tire should be good enough.
