Default What size aftermarket wheels?

Im interested in getting my first set of aftermarket wheels for my 2016 is300. Im looking at some 19in work wheels right now and I really have no clue what offset to run. Im on rsr down springs and I want my wheels to be flush. If anyone could tell me what offset their running or how to figure that out, that would be great. Thanks.

Welcome to the forum!

If you haven't seen the wheel thread yet, check it out: https://www.clublexus.com/forums/is-...exclusive.html

Some starter questions would be, do you want to run a square setup, or a staggered setup.
If your 300 is an F Sport, then you have the factory staggered setup...rear rims and tires are wider than the front.
If it's not, then potentially you have a square setup...all rims and tires are the same size.

With 19's you can go either square or staggered, up to you.
From there we can better suggest width and offset.

Thank you, and I have seen that forum, just wanted to see if I could get some more options. I would have to run a staggered setup because I have an fsport.

Even with the F Sport you can still run a square setup, but some like the look of the staggered setup with the wider wheels.

Typically with 19 inch staggered you're looking at 19x8.5 on the front and 19x9.5 on the rear.
Front offset would be +30 to +35, and rear you'd be looking for +38 to +45.
Tire selection becomes a little more critical as you choose something on the lower side of the range above.

Other options are 19x9 in the front and 19x10 or 10.5 in the rear. 10.5 starts to become a little bit challenging as you need just the right offset and tire to make it fit.
You will find it hard to find 19x9 rims also, so that's why you'll see mostly 19x8.5.

Thank you. I'm thinking about going 19x8.5 +30 offset front, and 19x9.5 +38 offset rear. The only thing I'm unsure of is if I should get +30 or +35 offset in the front. Whats the difference?

Literally 5mm...even though the rim size is expressed in inches, the offset is in mm.
To be on the safe side allowing you to run whatever tire you want in the front, I would suggest the +35.
