I had 17" rims with winter bridgestone blizzak tires that I got last year for my 2011 ford explorer. Could I put 17" rims on the QX, considering I do not want to throw away those almost brand new tires? Someone said that the base model comes with 18" being the smallest, hence 17 would be impossible. If I can match bolt pattern and spacing, would anyone know if this would be possible? Or are the calipers too big? They don't seem bigger than the explorer ones though!

Yes 17 inch can work ...you need approx 30inch of height
Search tire fitment on Google and you can determine and equivalent height in 17, 18 and 20 inch tires etc.
I have 20 inch wheels and for my winter set I have 17's no problem

Thank you for the response. However, I would be curious how the odometer and speedometer get affected because of change in wheel size. Does everything have to be re-calibrated? How complicated is it to do that? Thanks!

The point is that if the total diameter of the wheel/tire is the same, you are fine. You need to find a fitment that does that. If you get a 17" wheel and low profile tire, you will be off on speed and, no, you can't recalibrate it.

see the site below and examples of what tires between 20, 18 and 17 will provide an equivalent height/size. *

Tire Size Chart

235/55R20 = 30.2x9.3R20

235/65R18 = 30x9.3R18

235/70R17 = 30x9.3R17
245/70R17 = 30.5x9.7R17
