Has anyone here seen or heard of someone putting 4th gen 20 inch wheels on a 3rd gen RX? How did it work out? I have access to some 20 inch wheels off some 4th gen's and am considering putting a set on my 2011. Might go with the lux wheels because I think they'll match the body style better.

 

They will bolt right in and should clear the brake calipers just fine. Lexus would not change the hub centric diameter, bolt pattern or offset as the suspension and brakes are about the same as the 3rd generation. The 4th gen was more of a body redesign, not a chassis redesign.
Others have put aftermarket 20 inch wheels on with no issues.
You should go for it. You should get 245/45-20 size tires to match the original diameter.

 

Thanks for the input. I'll check it out and post with an update if I do it.

 

Hi, would somebody know if 4th gen 18" will fit on my 3rd 2015 F-Sport? The tires size on the 18 are 235/65R18.

Thank you in advance!!

 

They will fit just fine. That part of the car did not change between 3rd and 4th gen. Meaning the brake and wheel hub are the same.

 

Ive seen a 3rd gen with the 4th gen F sport wheels
