Tire Concerns: is it ok to switch tire size on AWD

I am looking for alternative size tires for 2007 Merc Mountaineer AWD with 235/65/18 factory spec tire.

Comment:

The big concern with AWD or 4WD vehicles is that all wheels have the same size tire. In theory there is no problem with switching to different sizes as long as they are the same on all wheels.

Use our Tire Size Calculator to compare the effects of different tires you might want to consider. The best effects are generally found with tires which stay within 2% of the original size. (That is the default setting on the calculator.)
