I recently had a flat tire. First flat with this car. I have a 2008 AWD edge with 20" rims. I like that the spare is in the cargo area, but I was surprised to see that spare tire/donut is 17".
I was under the impression that with AWD it was important to run all 4 wheels with the same tire size. The spare tire area is big enough to store the full size tire in there when the spare is on the car, so why wouldn't they supply a 20" spare on all vehicles with the 20"rim/tire?
I bought the car used, so maybe the dealer switched the spare??
Has anyone else run into this issue?? Is the 17" spare standard on an AWD with 20" rims? Or is it no big deal to run a smaller spare tire?
