Hey, all

So, only because this was an issue with my last wheel and tire purchase than I do NOT wish to replicate... Im trying to get a set of replacement wheels for my 06 RX400h (the stockers cracked on a curb avoiding an accident) a friend of mine has a set of chrome wheels (same bolt pattern, 5x114.3) running 245/45/20. Ive seen a few members running such setups, and it seems that is usually works. However, the last vehicle the wheels were mounted to was a 2009 Mustang... this is telling me the offset might ***** me, right? It appears my factory 18s have a +38, and stock Mustang has a +45... Than again, the 20s are obviously not its stock wheels... Anyone know different? Id just do a quick test fit, but the wheels are about two hours away and dont wanna waste the fuel, and obviously my car is no shape to drive that far on cracked, bent wheels.

Thanks for the help!

I have the rx330, and my offset is 35. I put 17x8s on with ET of 40, fit fine. kinda close where the wheel weights are double stacked, but it clears it.

I have 20x8.5 wheels on my 06 RX400h, offset +25. Tires are 255/45/20. No issues.
