on H&R springs. Will I be flush and run into front fender rubbing?

yes.

there's no way you can run those tire sizes without damage to the fenders/tires - especially the rear.

you'll need modified fenders to start, and run narrower tires. 225/35-19 + 255/35-19 come to mind, but 245/35-19 will have more clearance.

if you don't roll your fenders, yes, you will run into fender rubbing - front and rear.

would fender rolling allow me to run it with a lower offset to be more flush?

the true issue is w/ the available offsets given the wheel widths. to refresh our memory for discussion's sake...

there's not much you can do for the front, as the difference between 18x8 +35 and 18x8 +38 is... 3 millimeters. neither offset will need fender work.

in the rear, 18x9 +38 will not need fender work, 18x9 +28 may (depending on your tire size), and 18x9 +15 will.

i recommend higher offsets to avoid fender work and/or to have to run narrower sized tires for clearance. also, higher offset wheels can allow you to run wider tires. anyone who's driven the 2is aggressively can tell you that the OEM tire sizes leave a lot to be desired.

I have a set of 18x10 5x114.3 +12 offset. Does anyone know if ill have to rub my fender even if its not dropped? And a good size tires i should get? im afraid the width might be to long and i just wanna know how itll fit if it doesnt fit .

Palmiholm

Ok, I get it. I think I will like this setup/stance Kind of OEM look
What about a 1" drop via F-sport springs ?
19mm rear and 25mm front
Will that work with this proposed setup?

Thanks again

What would you guys run in an is350? 18 inch? 19 inch? My goal is to get a slightly wider stance on the car but i prefer maximum amount of tires in the rim not a fan of the stretch. I'm in the market for tires and just want to make sure I'm headed in the right direction

RVCAis250

it's personal preference. obviously the size of the face of the rim has nothing to do with how wide it is. So you can stick with 18's and do a staggered setup with 18x9 front and 18x10 in the rear. Tire sizes will matter once you actually have the specs of the rims, otherwise there is no point telling what spec tires you should get.

yes.

235/35-19 with a fender roll.

the width is fine. it's the wheel offsets that, in this case, force you to run some thin tires over wide wheels aka "tire-stretching".

it'll work.

there's no preference, though the 2is does come w/ 18" wheels/tires from the factory (moreso the rule than the exception).

if you want as much tire as you can stuff under the fender sheetmetal, here's a few rules of thumb.

1. given the same wheel diameter and width(s), high offset > low offset for "max tire"
2. wider is not always better. the wider the wheel, the smaller the range of tire sizes you can fit.
3. buy a set of wheels to fit the car, not vice versa.

I had 225/40/19 fitted today and the tires rub the inner fender cover in front and rear of the tire while 45° turn. Should i just heat the plastic and mold it. ?

before going further, i have to apologize for not reading your initial post correctly. i misread it and was under the impression that you were asking about 18" wheels and not 19" wheels - which you have.

the 225/40-19's are OEM size for the IS-F, but they're one aspect ratio size taller than what would normally be for the 2is. what you should have opted for is 225/35-19 in the front. however, that's not to say that 225/40-19 won't work...

as you posted, yes, just heat the plastic and push it out of the way.

again, my apologies.

Palmiholm

Thanks again no problem ,they were just trying sizes ætla the tire shop.
Ok , but going to 225/35/19 will have a significanly lower sidewall height.
And lower than rear sidewall. 255/35/19
Won't that be worse ?
With the setup I spoke of earlier will an f-sport drop be a problem?
Fender above the tire seamed to have some clearence.

Maybe keep in mind that ride quality is my concern.
Thank you for your help

the difference between 40-series and 35-series for 225's in 19 is ~11mm. since you're looking to run pilot super sports, you shouldn't lose too much of your ride quality - PS2's have slightly softer sidewalls.

with the set-up you referenced, you won't have a problem w/ f-sport springs in terms of clearance. your ride quality should firm up a bit but not get washboard stiff (or worse, sloppy).

Palmiholm

Ok, I think I will go with :
19x8 +35 225/40/19 for front
19x8.5 +35 255/35/19 for rear
I like the idea of a little more rubber around my wheels
Also not sure about the drop due to i'm in Iceland

So will rear be OK? Fender rolling possibly ?

F-sport springs at later time maybe.

Thanks

Griiix

could some please figure out what the spec on those SP3?
really wanna get the SP3 with the deepest lip i can get with just a fender roll.

thanks!
