Something is not kosher in Denmark. There is no way those tires should be wearing out in 12k mi. What kind of wear do they have? Are they worn evenly across? Do they have cupping? Are they worn on one edge or both edges? Do you keep them inflated at least to what the manufacturer recommends? Are all 4 tires worn out or only the fronts? Do you have AWD or just 2WD? Have you ever had the alignment checked? Did they (or you) have it checked when the 1st. set of tires wore out? I don't believe you have caster or camber adjustment on an RX- so if you bought it new and haven't done any damage to it, toe-in or out are the only adjustments. Nitrogen isn't going to have any affect on the tire wear other than not loosing pressure as fast, and you should be checking them once a month no matter what you have in them. Most people don't check them near often enough and that is hard on a tire (destructive) to run it too low on pressure. I run my tires at a minimum what the factory says and most of the time 2 to 3 lbs. above factory recommendations.
Good one. Yah the tires are slightly more worn on the front set, and they are all evenly worn - no cupping etc. It's a 2WD and when they gave me a new set of tires after the first 12k they did a full alignment so it should be running even. I took it in cause it was drifting and the tires looked worn and they gave me the same ole story as they did 12k ago. Tires are always at the right pressure. Its got a low tire pressure sensor so the light would go on and plus for oil changes they check and fill as needed.
THis was all this past THurs Oct 2nd. I told the service guy to "F" off when he said we are going to install new tires and align the car and charge you. Told him to speak to the manager then call me, and still havent heard back. I guess Im keeping the loaner car a while longer.
