Hello all..I have 2011 Rx 350 AWD with the 19 inch wheel package. I want to upgrade to new wheel and tires. My issue is should I go 20's or 22's. I had the math done when it comes to speedometer and I will be doing 59.7 when it says I am doing 60 if I go with 22's. The 20 option is 59.9 MPH. I would like some sincere opinions. The Factory tire is a 235/55/19, I would be going to a 255/45/20 for the 20's or a 265/35/22 for the 22's. I had a tire shop place the 22 inch tire next to the vehicle and I must admit it looks nasty(In a good way). I am asking for some opinion solely about ride comfort. My wife has approve for going with chrome with a black accent. My vehicle the Tung Pearl. See pic below. I have match the tint in front and had the clear bra done aftermarket saved a ton of money (400). Let me know what you ladies and gentlemen think...

The sizes you have picked are in fact close to the rolling diameter and would not change the OD or speedo, but The Tire Rack has recommended fitment data for the 245/45R20 being a better overall fit. This size is shorter by 4/10th's which would help accommodate the wider tire. I'm sure in some instances people have used the 255/45R20 but since the tire is the same height and 3/4" wider there would be the potential for rubbing when turning full lock to lock, usually this is just when parking. Now, if this is your wife's daily driver and she would like to retain some of the ride quality of the vehicle I would advise against the 22's, as there would most certainly be a noticeable difference in ride quality. Also, the width of the tire needed to meet the proper load for the vehicle is an XL tire in the 265 range and these will definitely have some rubbing issues and would require some modifications. In the 22", since the side wall is losing 3" the tire needs to become wider to make the air chamber large enough to carry the vehicles weight and in 22" you would be very, very limited on what could work.

Thanks for the reply, I guess I will go with the 20's. Although 22's would look very nice..thanks for the info.
