2007 RX400h - How big can I go?

[moretea]

Hello folks,

I have recently purchased an 07 RX400h which I really love. I don't mind the current wheels on the car but I have a notion to go bigger.  This may have been asked before so forgive me, but what size realistically can you go to on my car and what tyre sizes would be suggested as a good and user friendly fitment?

I was thinking of 19" or 20" max.

Thank you

You can put 22 inches on the RX if you want - itll handle it no problem

Thanks Rayanns, as much as 22" wheels would look quite something I just can't - potholes are a plenty in my part of the World and 20" with a good sized tyre would be my best option.  Good to know they can take it though!
