This Galant VR-4 has Full-time AWD & AWS. Check tire pressure weekly. Rotate front-to-back around every 7000 miles. Feedback from steering wheel and suspension is very sensitive so I know when something needs attention. I keep it aligned. The AWD on this car is hard on tires. These tires are lasting longer than the Falken ZE512's and ZE912's. When you consider that I live in Oklahoma, tire wear is amazing. Quieter and better ride than Yokohama Avid H4s. Yokohama took all the complaints about previous Avid's and tried to overcome those problems with this tire. Handles as good as Falken's. Handling test has consisted of coasting at 45-55mph into turns rated for 25mph--backs people off my rear bumper.
I bought these about three months after manufacturing month (3 week of May 2010). Date code on sidewall was interesting because on one side it has a raised, rubber bar-code. Manufacture warranty is ok. I think Yokohama did a good job. I checked the Yokohama site and they have a rating for these tires that closely follows my rating. (http://www.yokohamatire.com/tires/detail/avid_envigor). I bought them for $83/each. I see they are listed for $82 on 2012APR23. If I was certain that tires don't go bad while just sitting around (http://news.consumerreports.org/cars/2009/05/tire-aging-when-to-buying-new-car-tires-based-on-age.html or http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=138), I would buy another set and just store them in the garage. I would definitely recommend these.
