I'm planning on buying f sport wheels all 19x9 but have no clue which size to go with ?

RandyIS250

225/35/19 offset 40 or

wanna go big ? 235/35/19 offset 35 , your wheel will be like those BWM M-series and Mercedes AMG

i'm running on 225/40/18 because i don't wanna spend too much i'm IS250 AWD as well.

i think I'm just gonna get a light weight 17 rim instead !

RandyIS250

255/40/17 if you wanna alter. otherwise you go with OEM size.

if you don't want to go 19" my recommendation 235/40/18 Rim 18x9 offset 35 trust me bro you won't regret.

255/40x17s won't fit on the front. You're limited to 225/45x17 or 235/45x17 square on 17x8" rims on an awd. Make sure the rims clear the brake calipers.

I've run 245/40R17's on the front for years with the RWD Sport suspension (lowest factory 2ISx50 suspension) without any rubbing whatsoever. I've also been running tires that typically fit wide (RE-11A and now RE-71R).

I would expect some 255/40R17's would likely clear the front on an AWD pretty well, but 245/40R17 is definitely not an issue.

I finally purchase f-sport forged gunemetal wheels ,there all are 19x9 offset 40 ! On discount tire is has the original size what came on the car which is 225-45-17 and has a plus 2 column which says 235-35-19 is the tire to go with to have the same rolling diameter!

235/35R19 should work, especially if Tire Rack publish this. There are some threads on this forum complaining of rubbing with 235s on the IS250 and OE wheels but I've run 235/45R17 square for 8 years with no problem.

It was discount tire that published that 235-35-19 would be the same as the oe wheels & thanks
