Will wheels from an 2011 RX350 work on a 2007 model? Here's what I see on the inside of the 2011 wheel: 18x7 1/2 J 35, on the 2007 it says 18x7 JJ 35.

I guess the wheel is 1/2 inch wider but what do the J's mean? and why is there only one for the 2011. Are these wheels inter-changeable?

Thanks

 

Wheels will have a letter designation for their contour or the expected tire bead and rim shape.
Some possible contour designations are J, JJ, K, JK, B, P, and D
Common (and generally interchangeable) wheel contour designations are J, JJ, and JK.
J is the most common type for most automotive rims
JJ is common on 4x4 vehicles
Basically the rim contour and bead profile specify the shapes of the rim flange and the bead area.
You generally want to stick with something the same or close to what you have.

 

I think youll be good.

I never look at the letters. only Diameter width and offset. If those are the same you should be good.

 

The 2011 seems like its a little wider by 1/2 in 18 is diameter and the 7 1/2 is the width not sure if the extra 1/2 will make difference from rubbing on the sidewall

 

should be 100% fine. Sam lug pattern and with an SUV you dont need to worry about rubbing . Its going to fill the wheel wells better. Go for it

 

I have 19" oem rims from 2012 RX installed on my 2008. With tires that are 255/45.
A little too heavy. Much heavier than original 5 spoke 18" but car feels more planted. MPG is worse by 2-4 mpg.
