| 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 | |

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. |

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? Thank you George

Replying to: carfun888 (Nov 21, 2009 9:15 pm) 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.

Replying to: steve_ (Nov 21, 2009 9:20 pm) I think it is a scam. how much rolling resistance difference can there by between redesigned snows from the same mfg? If that is really enough to quickly wear out a differential?

Replying to: fisherboy (Nov 22, 2009 9:50 am) I posted some tire sales over in Auto Parts Bargains and Coupons not long ago, but some may have expired. But tires always seem to be on sale. 4 for 3 is a better deal than the $50 or $70 off a set sale too. |
