#2390 of 2400 Sequoia 4WD system by guch Oct 13, 2009 (5:48 pm)
I need help with understanding sequoia system. I am planning on buying this truck for my wife. Since it is a RWD truck I worry about her driving it on wet roads and in snow. Switching to 4WD seems to eat a lot more gas so it seems like a waste to drive in 4WD in just little rain or snow. How is Sequoia's traction control and vehicle stability control going to do in these conditions? Dealer says it does greatith VSC alone withput need to turn on 4WD. My other option is to get Lexus GX 470 or 460 when it comes out , these are full time AWD.   Thank you for your advise and help Replies to this message: wwest (Nov 08, 2009 3:58 pm)
#2391 of 2400 Confused about 4WD/AWD by robnny123 Nov 08, 2009 (2:31 pm)
Do any current SUV's have a selectable 4WD/AWD mode, it seems to be more fuel efficient while most of your driving is generally 2WD. Thanks

Replying to: guch (Oct 13, 2009 5:48 pm) In reality RWD vehicles are a lot more safe in adverse roadbed conditions than their FWD and/or F/awd "brotheren". Even if your wife should leadfoot it a bit inappropreately the RWD vehicle will still have available traction at the front with which to sustain or assume directional control.   Whereas with FWD or F/awd absent Trac she would be in rather serious jepordy. That's why owners are complaining so LOUDLY about the aggressiveness of TC in their FWD and F/awd vehicles. Absent TC's aggressiveness upon detection of even the slightest level of wheelspin/slip there would undoubtedly be a lot more accidents attributed to FWD and F/awd vehicles.   Just think of TC as the inverse equivalent of ABS, it's there to save your life.
#2393 of 2400 Replacing Tires Question by fisherboy Nov 20, 2009 (1:11 pm)
I have a 2000 LC (love it, had since new) and have run dedicated snows on it in the winter. I have DMZ2 Bridgestone and hit something in the road that trashed one tire. They have low miles (<5k). I cannot find a 275-70 16 DMZ2 to replace it as they have not made them now for several years. NTB/Sullivan Tire are both telling me I need to replace all 4 tires or I will trash the AWD system as different snow (even the DMZ3) will have different tread pattern = differnt rolling resistance. They claim the AWD system will see slippage all the time instead of temporary (as it was designed for) and wear out the system. They claim they will not even mount a single snow of different tread type. Even if I replace 2 (same axle). My question is, is this overkill or not? I have 120K on my LC and would like to keep it and do not want to create problems, but my engineering mind says if I mount two of the same on each axle, even different treads (but close) I will be fine. What would you do? Throw out 3 perfectly good tires and drop $600 to replace? Replace 2? or 1?

Replying to: fisherboy (Nov 20, 2009 1:11 pm) I NEVER rotate the spare so it is always available in the kind of instance you have.   I would NEVER replace only one tire on an AWD vehicle, 2 at the minimum.

Replying to: wwest (Nov 20, 2009 7:29 pm) Replacing 2 on the same axle is probably alright then? Replies to this message: wwest (Nov 21, 2009 2:38 pm)

Replying to: fisherboy (Nov 21, 2009 11:36 am) Same tire size, and only 5,000 miles on the others, I would say yes.

Replying to: wwest (Nov 20, 2009 7:29 pm) How does not rotating the spare help the situation where one tire is destroyed? By rotating the spare wouldn't it be approximately the same treadwear as the remaining 3 tires? Then a new tire can be purchased as the spare. Once the primary 4 need replacement reintroduce the spare to rotation. Replies to this message: steve_ (Nov 21, 2009 9:20 pm) fisherboy (Nov 22, 2009 9:50 am) steve_ (Nov 22, 2009 10:30 am)

Replying to: carfun888 (Nov 21, 2009 9:15 pm) You can shave a tire to match the circumference of the other three, so that would be an option if you choose not to put the spare in the rotation, and there's a significant difference between the spare and the other three remaining tires. It may take a bit of scouting around to find a tire shop capable of shaving the tire.   I have a flat on my Subaru right now and I'm hoping that it's an easy fix, since my spare is a space-saver.   Tirerack has a page about replacing tires on AWD and 4WD vehicles. They recommend rotating the spare on 4WD/AWD vehicles. Replies to this message: fisherboy (Nov 22, 2009 9:50 am) steve_ (Nov 22, 2009 10:30 am)
