thanks for that review, amazing. good to know it makes that much of a difference. i can imagine how sensitive her back is to the rougher ride of the 22's. I take it that 20's make a big difference.I recently bought the 2014 QX80. After test driving both the base model with the 20" wheels and the high-end model with 22's, I asked my dealer to switch out the 22's for the 20's mainly because my wife, who has a chronic back problem, couldn't tolerate the ride with the 22's. The dealer changed the wheels to the 20's, we test drove the vehicle twice, and my wife loved it both times. I also noticed a big difference in "smoothness," which I expected because the metal-to-rubber ratio drops with the wheel size. Anyway, it rides like a dream now and we are very happy (but still in the honeymoon period).
I couldn't give up on the 22's...I have the 22' wheels that came standard on the car but I wanted more capable 4x4 tires for weekends in the desert and I got the stock 20' wheels and put on the Nitto Ridge Grappler Tires. I now use the Nitto Ridge Grappler Tires with the 20' wheels as they eat up every little pot hole in San Diego like nothing. The ride has become incredibly smooth and amazing. The 22's look really cool don't get me wrong and are super quite and fast but if you want an aggressive looking 4x4 with soft supple ride the 20's are where its at.
It handles amazing! These tires are way ahead of the K02’s in my opinion. I put these on my Armada and my work truck 2500 RAM Diesel, they slip and slide all over when it gets slick out. We had freezing rain here last night and the QX kept it’s composure like it was riding on an ice tire. In the dry these tires stay firm and keep the HBMC doing what it’s supposed to, keep it level and tight in the corners. The more I drive on these it reinforces the price I paid for them, totally worth it!This is great to hear that the 285/55/R22 size fits without any needed tweaking on the vehicle. I have heard death stories about the ABS system engaging on the freeway when people went to 305/45/R22. I can't wait to try out the 285/55/R22. Does it handle better in the turns as well with more grip?
I personally bought the Infiniti because I love the comfort, reliability, size, towing capacity, and captains chairs for the kids. Other important factors were the cooled/heated seats and interior layout. This is where the Lexus looses me, the interior is clunky, not refined like the Infiniti. The resale on those are also redick, putting it out of my $35k price point for a used rig with 60k miles.These are all valid and well thought out responses. But, if you really want 20's, you could have saved a lot of money and just purchased a Nissan Armada or the base QX80. Basically the same vehicles, with 20 inch wheels/tires.
As for ride comfort, ditto for the Nissan Armada or base QX. But, just think about 22 inch wheels, tires and what translates to a beefy, huge land yacht the top INFINITI QX80 is. It makes such a statement, that what you see is what you get.
If you want to float, get a Lexus LS.
