I've tried to search but haven't been able to find the answers I'm looking for. I am in the market for a winter setup and I'm interested in finding out if stock IS300, GS300, or GS430 wheels will fit my 06 IS250 AWD. I know that the sets below have a matching bolt pattern of the IS250 which is 5x114.3 but I'm not sure about the offset and whether or not they will have problems clearing the brakes. I

IS300 - 205/55/16
GS300/430 - 225/55/16

Thanks in advance for any info

i believe the GS wheels will fit if they are the 3gen GS. You will have to have the same rolling diameter as your stock tires.

Exactly what do you mean by rolling diameter? My stock tires are 225/45/17. Would my rolling diameter be 45+17=62?

I've been wondering the same thing about the IS300 wheels. Anyone know?

Anyone? Bueller?

No. The 45 is 45% of the 225. So I believe it would be 101mm+ 17inches. I'm too lazy to find the conversion to get the actual final number.

OP, the 17 and 18in. 3rd gen GS wheels definitely fit, not sure about the 16's. I'm actually using the optional GS rims (Machined Tourmaline 18in rims). They are 18x8 all around with same offset as our stock 17in. rims on AWD.

the 16" have about the same diameter but you will lose some performance because it is a tall series tires. Your overall diameter on the tires are 24.9" if you are with a few tenths you are ok.

IS300 & GS 2Gen have different bolt patterns they will not work on the 2gen IS

Will a set of OEM IS AWD alloys fit 'plug & play' on an 05 ES 330? I'm about 99.9% sure they will (even if they are 8" in width). Just need to confirm. Any help is appreciated.

I tried a search for the detailed specs but was unable to find anything.

I guess I'll be the first one to put these wheels on an ES lol. Will post pics.

And to confirm....yes they will fit.
