If you check, there are pics of an IS-F with 20" x 11.0 rims. I believe you'll see the pics under the title "My IS-F with some goodies".Me personally I wouldn't go with a taller tire maybe a 19" that'll be wider but not taller, 19" is a good size but with a 285/30/19 would be nice. Also you dont want to add any more weight because the factory rims are LIGHT you would need to get something just as light if not lighter.... jmo

I know this sounds crazy but if you look at the F-Sport catalog the rims are the same size as the factory IS-F rims except the F-Sport rims have a 5-6" lip and are forged in gun-metal,, they look nice and like I said they the same size so no need to get another tire size.The price though might be a little high it'll cost you about $1200-$1500 each ....

But you know what unless your going to the track,,,, this car really is good enough for the street of course a wider tire for the front and back would be better and look better too, IMO just for the street it's fine the way it is..

"one more thing. the Fspot rims DO NOT fit on the IsF"

That's a shame,, why wont it fit they're the same size 19", tire size for those rims are 255/35zr/19 and I was told they could.These are the same specs from the factory IS-F and I spoke with the mechanics...??

Smoke, I remember hearing the Sport wheel will not fit because they will not clear the brakes....

OK, I can see that happening it hasn't been tried so maybe that's why they say it would.Now that you say that I understand. Thanx
