As mentioned in another thread, I have a GX460, which is full-time AWD. For directional tires, which can't easily be part of a five-tire rotation, what do people do for spares, and how far and fast can you go without damaging the transfer case or other components? Around town would be one thing, but on cross-country trips of close to a thousand miles in a day, the inability to finish the trip makes a directional spare unappealing.
Yes, I have read the manual. It is not helpful - it says "Do not mix tires of different makes, models or tread patterns. Also, do not mix tires of remarkably different treadwear." It also indicates a non-crossing rotation, with the spare included on the passenger side (and the dealer has never done so to my knowledge). Even following that, the spare (and the passenger side tires in general) will perforce have lower treadwear than the driver's side tires. What's "remarkably" different, and can a long road trip be finished? What if it's a driver's side flat and the spare is pointing the wrong way?
The original question remains - what do people do for spares in this situation? Is it simply not worth running directional tires on AWD?
