Default 2Gen IS - 18` rear tires size?

Hi.
While i`m waiting for my pro-kit I`m also in search of tires for my oem 18` rims. And there is one question about it. What if i put them in 225/40 - front and 255/35 - rear? The original sizes for Lexus are 225/40 - 255/40, and i think that`s why rear wheels (18`) look so small, like 16` or something. So i want to ask would it be ok if i put 255/35 - rear, like on BMW 3-er.

And one more thing - can anyone help to find thread whith fotos of 2 gen IS on eibach pro-kit and 18` oem. It was there some time ago but now it`s gone. Thanks.

^^^ Do you have a photo of your OEM 18x8.5 with 275/35R18? Doesn't the sidewall bulge with an 8.5" rim?

For an 8.5" rim, 255/35R18 or 265/35R18 is the max i'd go with. Beyond that the sidewall would bulge a bit.

What does the 255/35 look like compare to the 255/40? Is there much of a visual difference?

its about .5 inches smaller, go to 1010tires.com they have a calculator that will give you the dimensions. I had the same issue when i got my rear tire, there is a difference between the two... and it is noticable.

275/35/18 rear and 225/40/18 will change your speedo reading.
