20's probably looks best on our cars, but it all comes down to personal preference.

I have a 2005 ls430 what's the offset for some 22"?

My best guess would be a +20 to +30 offset if you do a 22x9 or 22x9.5 up front.

For the rear I’d say +25 to +35 offset on a 22x10 or 22x10.5 wheel.

Please bear in mind that the chassis and suspension of an LS430 was designed for 16" wheels.
As the cars age multiple posters report wheel bearing (hub) failure at right around 100 K miles on cars factory equipped with 18" wheels.

Increasing the unsprung weight has many consequences. None of them good.

Starting with the 2004 LS430, Lexus increased the standard wheel to 17" with an option of 18". The Sport model had 18" wheels as standard equipment.

Keeping the weight as low as possible on these tire wheel combs helps. The factory 16's weigh in the range of 52#'s with a Michelin AS tire mounted. Looking at the various weight charts of factory setups is helpful as well as what the wheel and tire weight is. Some of the 18" tires have been a spread of 3#'s and that can be pretty significant. More so on aged rubber type suspension bushings.

Agreed, my 05 has 18" wheels from the factory, that's not my point. I also have worn out wheel bearings @ 110 K miles, judging from the threads here I am not alone. I'm more pointing to the fact that the chassis and suspension design is circa late 1990's. Automotive fashion brought larger and larger wheels and Lexus went along with the fashion trend. Performance is the often quoted reason for the large wheels and low sidewall tires.
I like the look too, within reason. I do love the handling of my LS, yes it leans, get used to that and the darn thing is on rails. Wheel bearings failing at low mileage in a Toyota product is not normal, they get that stuff right, engineering wise. I'm no expert on this car, I'm here to learn. I see no real difference in suspension parts across the LS 430 years. I think the marketing department used up the engineering departments 'margin' of reliability here.

If you have a 2095 UL and it has 18" wheels, then someone has changed to 18" from what it was produced with. The UL was designed and produced with 17" wheels. The 18" wheels were only available on the Sport model, which had different suspension parts. I have more confidence in Lexus engineering and production than peoples opinions that might differ.

Ricklin

My 05 UL came from the factory with 18" wheels. It's on the build sheet that Lexus.com provides. Yes, 18" was optional on the sport package.
Mine is the car where the previous owner said, everything please.

My 06 ML came with factory 18s. I would like to believe Lexus built the car with that size wheel being a likelihood.

My '05 CL came factory equipped with 18" wheels as well.

As long as the wheels aren’t extremely heavy you should be okay. I’ve had 20 inch wheels on my LS430 for the past six years without any issues. My wheels aren’t extremely heavy by any means though so that could be why.

Ricklin

I've been a Toyota guy for a lot of years, my very first new car was a 1975 Celica GT. Wish I had it back, it's now a classic.

Learning that wheel bearing failure is common on the LS 430 at around 100 K in not the Toyota I know. They generally get that right.

Longevity and reliability are hallmarks of the brand. Thus my opinion that their engineering margin was consumed. The engineers do not have a crystal ball. I can't recall a wheel bearing failure on any other Toyota product I have owned.

I hear about them failing on the higher mileage cars. I hope it doesn’t happen to me but hasn’t been an issue on my 2005 LS or my sister’s high mileage 2002 LS.
