Anyone used 235x65R18 tires on their 2010 RX? The newer models work with these specs.

 

WHY?
That newer RX is 2 generations newer, with a different design, different transmission, different suspension, gearing etc. There is no reason to put a 235/65/18 on a vehicle designed for 235/60/18. It will throw off the speedometer, mileage, acceleration. The 65 aspect ratio tire is .93 inches taller according to the tire rim calculator on the CL link at the top of the page. https://www.clublexus.com/forums/tir...calculator.php

 

I might add that not all 235/60/18 are the same size. verify each manuf, for sizes.
