Hey guys,

Not sure if this has been discussed before, but has anyone put staggered IS350 wheels on an AWD IS250?

I know when I had my Subaru Impreza WRX, you couldn't put different size wheels or tires because that messed with the differential. I'm just wondering if it's the same case here. Has anyone done it?

Thanks!

I would not recommend it but there is a thread where people have done it and have not experienced issues.

Oh I see, well thanks for the response. I figured it's not recommended.

BTW, does anyone know if the rim sizes are different between front and rear for a IS350?

lol you're going to get flamed so hard for starting this thread.
Theres a huge thread on this topic
You should search next time, that thread has answers to all ur questions

Oh I'm sorry, I thought I was on a Lexus forum, not Honda. Thanks to everyone who answered my questions.

Since half the people on here say its ok, while half say its not. I decided to call corporate. I actually called 2 days ago and asked if you could put the stock 350 sport wheels (18x8 front. 18x8.5 rear) on an 07 IS250 AWD which is what I have. They said its ok and to run tire size 225/40/18 for the front. And 255/40/18 for the rear. So if you want to do an 18" staggered set up its ok.

Tell corporate they're a bunch of idiots because the rolling diameter of that setup is insanely off and would mess up your awd system over time.

That calculator helps alot.

theres a staggered look from XXR wheels that keeps the same offsets and width of the rim but with a bigger lip in the back to give it a staggered look, check it out on www.1010tires.com

how is the rolling diameter off? 255 is just a wider tire then 225. The profile on both is still 40. The wheel height on both sets of wheels are the same.

And no offense to anyone on here. They know alot more about cars then I do. But I think some of these guys are throwing out theories. Everyone starts buying into it and all of a sudden its fact.

40 is the aspect ratio, meaning the sidewall is 40% of the section width. 40% of 225 is 90mm for the front and 40% of 255 is 102mm for the rear, that's a 24mm difference in diameter (just a hair under 1 inch). It is quite a large difference and not recommended. I don't know why anyone at Lexus would have suggested that at all.

If you want to run staggered sizes, I'd go with something closer than the stock RWD sizes, they are not suited to an AWD vehicle.

Fyi, I posted that calculator for a reason. So you could have plugged in those sizes I quoted from another thread and you would have realized that your best bet would be 225/40/18 and 255/35/18 since the difference in rolling diameters is under 1%.

But if you feel since the profiles are both 40 and 255 is only a wider tire, you can go ahead and go what with corporate told you and let us know how that works out.

Yeah running the OEM RWD 18" tire setup on your car will probably throw up a differential warning light!

another member on here is actually running 225/40/18 on a stagger set up for all 4 wheels on his AWD. I will try and find him and ask how he's making out

ltzSupra

His name is Phresh something with a black IS. I don't think id like a 225 on an 8.5 wheel. That's just me though.

mikez

Running 225/40 on all 4 tires is different than running 225/40 on the front and 255/40 on the rears though.
