yeah no worries mate ill let you know. Had the Mich pilot super sports so lets see how they compare. Read plenty positive reviews about the PS91's and as i dont track the car, wanted something little harder for the street for longevity but still good grip etc. Even though i still had tread on my MPSS, after about 13-15k kms, traction was crap and the traction light would come on with minimal effort, bit too soft for me.
Like you say, no idea how they go in the wet as it just hardly rains lately lol

What's your wheel widths and also front tire size
Fronts: 19inch x 8.5. 15 offset and currently running OEM size 225/40 (Mich super sports). Got a few months left and then ill go slightly wider (not too wide as my offset limiting me)
Rear: 19inch x 9.5. 40 offset with new PS91 Kumho 285/30 (needed to shave guards due to my offset). Very slight scrubbing but 90%+ of my street driving its not an issue. Mainly need to go slower over speed bumps

OEM 2008 wheels offset are:
Front 45
Rear 55

^^^^^^^From my understanding that's correct, 285 is the upper limit for a 9.5" wheel after that you would need to go to a 10" wheel to fit a 295

Im running aftermarket wheels with an aggressive offset (not my choice, i learned this well after wheel purchase) however unlike the early model ISF's the 2012 runs bigger rims .5 inch wider front and rear so im sure its like mine (8.5 and 9.5) and with the OEM offset you shouldnt have a problem.
Ive seen other people with 2012 wheels advise it fits without scrubbing either whereas i had to shave my guards due to scrubbing so should be all good with less issues than what i faced.

285/30/19 fits 2008 OEM wheels all day long with no rubbing (stock ride height). The later cars wheels are 0.5” wider and should be an easier fit.

I want to go with the higher tire wall too. How’s the ride and performance of this setup?

u should go 275/30/19 instead. 285 a little too much for 9.5". its gonna bulge over the rim too much an reduce your sidewall stiffness

Not True! 285/30/19 is a recommended size for a 9½" wheel.
