Almost all 4x4 pickups are a part time 4WD. Some have an "auto 4x4" that kicks the 4x4 on when it detects slip. The ones I have driven are slow to react. Some trucks do have AWD to drive on pavement, but many of these also lack a low range. Why would you need 4x4 on a dry surface anyway? I pretty much only use mine in the winter. I do agree though that the electronic LSD is [censored] compared to a real mechanical LSD. This is one thing I wish my truck had.
As for tire size, Tundras come standard with 255/70-18's which is an odd tire size. However, the TRD tires are 275/65-18's, the same as many F-150's making it a pretty common tire size. The diameter between the two is identical. I run the 255's as my winter tires, the 275's as my summers.
When it comes to Tundra long term reliability, the fact remains that it still leads in the only two independent long term reliability surveys, True Delta and Consumer Reports. My last Chevy had 250K miles on it when I sold it and the engine was still awesome. Other areas not so much which is why I decided to sell it.
