have any of u tried to go wider? whether it be on the stock wheels or get aftermarket wheels for the car. is the 225/255 really enough rubber if you launch the car hard to get traction?

anybody? with audi and bmw the first thing ive always done is go to wider tires. i find stock sizes are just not suitable for an agressive driver.

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

yeah. ive never been a fan of 20s. on any car. the ride quality suffers too much, esp in a performance sedan. and the thin sidewalls are also a concern even though CA roads for the most part are good.

i could understand 20s for an SUV/truck, but not a car.

im going to stick with stock wheels, i just want to know what is the WIDEST you can go in the front/rear on the stock 19x8 and 19x9 wheels.

also was wondering if i decided to get like CCW or 360forged or HRE make a set of wheels, whats the max i could go without any fender modifications/suspension modifications.

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. only the IS250/350
i asked. wrong offset. they WILL NOT be making any in the ISF offset. a shame too because with the lip, those are some good looking rims.

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
