I picked up some 19" OEM wheels from a 2012 RX350 for my 06 RX400h. I am getting ready to order tires and wanted to confirm 235 50 19s will fit without issue. I figured I would check to be safe. Thanks

It should be fine. I don't know much about the OEM 19's (wasn't even aware the size was available), but what I'd do to make absolutely sure is to double-check the offset.

OEMs are 19x7.5 35-60 offset. I test fit the wheels without tires and they are centered where they need to be. I see a few people using OEM 3rd gen wheels but they usually are on a bigger tire than I am using. I guess I just answered my own question as if a wider tire/taller fits, mine probably will.

They might be OEM for a 2012, but not necessarily for a 2006. Sure they might fit, but won't that throw off the speedometer and odometer?

The tires are very close in circumference so speedo will be fine.

If you think there's not going to be a difference in the speedometer, then go for it. I see that you are using 235-50-19 tires. The middle number is the sidewall height, and anything from 45-50 is considered low profile tires. There's less tire between the rim and the road. Because low-profile tires have a shorter sidewall, the sidewall is stiffer. The stiffer it is, the less it bends and flexes when you turn so you get better handling. The trade off is that this means a noisier and harder ride. The tires mounted on my 07 are the 225/65R-17s, so it is higher profile, for a quieter and smoother ride-- which is what I want in a Lexus.
