I'm shopping for a set of 18" winter wheels + tires to complement the OEM AS set.
The biggest challenge appears to be locating the right set of hub-centric wheels, as RZ wheel sizes are weirdly narrow, and there are not a lot of other Lexus models that share wheel specs:


Any suggestions on Toyota or other OEM wheels that might might fit the bill?

TIA,

You might want to go for the Michelin climate 2 tires, I have them on my Volvo Xc90 , they are the best tires that l have owned. I have gone thru 5 sets of tires since 2009 on the xc90.
l am going to replace my RZ summer tires for the climate 2 tires next year. It is about $100 more than winter tires, great all year round for us Canadians. You will save on mounting and balancing and storage fees that could amount to $300 per year. Best deal is to get them at Costco.

 

Those are all-season tiers.
That may be an option for you where you live and drive, but there is about ZERO chance of me putting any AS tires on my cars in the winter in NE.

Within Michelin family, X-ICE Snow tires are an option available in 235-60/18 size.
So are Bridgestone Blizzak DM-V2's.
I will be getting one of the two above.

I'm still shopping for decent WHEELs to support my dedicated winter tires. Price is not a limiting factor.
There are relatively few weirdly narrow 18x7.5" wheels on the market. 18x8" is more popular, but none are hub-centric for 60.1mm RZ hub bore.

To be continued.
