Can I run a small donut spare tire on Toyota Sienna AWD for short distances w/out damaging the AWD system?
I have just replaced the original RFT on my Toyota Sienna with Yokahoma TRZ. What an improvement in ride, handling, and tire noise. Now I need a spare tire. Can I use one of those little donut spare tires on my Sienna AWD for distances of 50 to 100 miles without damaging the AWD system. Some say it's OK and some say all 4 tires must be the same size. What is the true story here?
