interesting. so it comes with a non-matching spare?
why would they go backwards like that?
According to the dealership service manager when I asked ,it was because the spare tire getting low ,mainly in winter, and setting off the TPMS light was the number 1 service call for them.I owned a 4th gen and never had it go off for the spare but then I did check it's air pressure regularly.The 5th Gen TPMS ECU won't even accept a 5th sensor now.
I personally think it was more of a cost trade off.Some things were cut to add other things and keep the cost about the same thanks to the bean counters.
Here were the things that are upgrades(trade offs) from 4th to 5th gens IMO having owned both.
Per Toyota...Extensive frame and body reinforcements with braces have been added using high-tensile strength materials(aka new LC J150 frame),reworked engine mounts and a completely newly designed and much stronger rear 8.2" 12 bolt differential were added in 2010 .That's where the majority of the 300lbs of added weight in improvements over the previous generation are if I were to venture a guess.

Probably left out a few and I admit they did delete some things from the 4th Gen that were insignificant to me and added so much more.That's why I bought another 4Runner as they keep making them better IMO,a 5th Gen and have loved every single minute of it! Still Smilin' every time I drive it and it's almost 4 years old now
