I got a good set of used tires (4) and put em on there. $85 for just mount and balance but that’s how it rolls. Wierdest experience ever leaving the tire shop. Truck was clattering along like one or more tires seriously out of balance. I was like dreading having to go back and force the issue(s). And then within a few miles at moderate speeds the clattering went away entirely and then smooth running. Like? But that works. They put double balance weights on each wheel. They have the push ins at the inside of the wheel at the tire. And they have glue ons inside the spokes to the outside of the tire. In three cases, the weights are pretty much opposite each other on the wheels! I never saw anything like that before. Like they balanced each wheel twice? This is a very experienced tire shop, for the record. 😯

My thoughts exactly. I’m thinking that the 05-12 Pathfinder LE’s, when in 2WD, do not have the front transfer case engaged at all. There’s no hub lock or unlock on these. Unless selecting 4WD is what you’re referring to by manually locking the hubs. AWD is a confusing on this vehicle. I don’t think that the hubs are technically locked, but they’re obviously engaged, and the drive is put to the front by “The System” when it senses “Slip” I guess. And if your front tires are mismatched, it might sense slip continuously. I guess that I could put the truck up on the lift, start it and engage “Drive”(2WD), and just see what’s spinning. I would assume that the forward drive shaft always spins, but that the transfer case is not engaged. Another way would probably be to put on the new front tire on the front paired with the used front tire and go drive. If it’s a problem, the “VDC” and “Slip” lights would probably come on.

Newer AWD cars require the tire diameters to match all round so as to not damage the AWD transmissions. The 2005-2012 Pathfinder’s have 2WD, AWD, 4WD, 4WD Low selections. I drive in 2WD almost exclusively. I keep the rear tires the same diameter (degree of wear), and the front tires generally close to the same degree of wear. If you’re driving in 2WD, is there any issues running say a new tire paired with an almost bald tire on the front? My thought process is that the front transmission is free spooling anyway, and that no damage would be done by mismatched diameter front tires? Obviously, if you select AWD with mismatched front tires, it might create an issue with sensors and computer etc. But, again, I never had an issue using AWD or 4WD(rarely for say 1/4 mile) with matching rears and different degree of wear matching fronts. Input requested. Thank you.

Hi. I’m new here. Quick question about tire matching. The new AWD cars require tread depth tire matching in order to not mess up their AWD systems. I have an 05 Pathfinder LE 4WD version. This has the drive selection for 2WD, AWD, 4WD and 4WD LO. I don’t use anything but 2WD. I understand that, in 2WD the rear wheels are active and that it’s best to tread depth tire match that rear axle. But, since the front is not engaged, is tread depth tire matching required in the front if only 2WD is ever used? I know best practices and all that, but I have a bad front tire and the other side is well worn. I was thinking of just running the new full size spare.
