Is there Amy problem with doing 18" in the front 225/35/18 and 19" in the rear 255/35/19.

I haven't seen anyone do this. Will this effect the speedometer? I was thinking it may give it a more aggressive stance.

Thoughts?

Run 225/40R18 and 255/35R19 and you'll be fine.

Sorry I meant 225/40/18 in the front.

Any thoughts if this would look good or weird?

I actually think it would look pretty good. Using the sizes I gave you would have the exact same sidewall height on both front and rear, while keeping the same overall diameter to the stock tire sizes.

I'd have to see it before making a final decision, but it could be pretty cool. I wouldn't take the risk myself though, haha.

Good luck on your decision .

To be honest it not worth it for resell wish. Your not gonna get someone to buy that set as an whole due to the setup but that just me.

You should be fine.

225/40/18 = 225/35/19 (0.5% difference, which is Lexus' recommended tire size)
255/40/18 = 255/35/19 (0.04% difference, again Lexus' recommended tire size)

Also, you can check out this website to check other sizes: http://www.1010tires.com/TireSizeCalculator.asp

Personally, I think it may look good, depending on the car. I was even thinking about doing staggered size with a 20" rear wheel, but a 30-series tire in my area =
But, 2 door vs 4 door makes a big difference in looks.

Ive seen photos where this car does make the rear wheel look a tad smaller so this wouldn't be a bad idea

Yep......especially on the IS-C

Although, a lip on the rear seems to help. My 18" g-spiders (flat faced) didn't look so great on the vert.
The 19" ISS wheels with a rear lip make the rear look much larger than it really is.

Since my rears are spec'd to F-sport specs, I'd assume the same visual effect may be seen......although since the F-sports are one color I could be wrong too

Does any one have pics of 18 f-sports in the front and 19 f-sports in the rear. I thought about doing this for some time I might do it this summer.

I'd like to see a pic too.

Off the top of my head, I can't think of anyone on the forum that's done it yet.

...at least, not with f-sport wheels.
