Looking to purchase new set of summers for my 09F.

Current setup is Ventus V12 225-45-19 front, 255-35-19 Rear.

The car was purchased lowered, i am not sure what brand springs they are. Only thing i know is they are gold. Maybe Teins?

Looking to upgrade to Michelin PSS 245-40-19 and 265-35-19 but not sure how to calculate clearance. Ive heard the sidewall is bigger than most other brands.

I brought it to Lexus dealer but was told they didn't want to be responsible with ordering wrong tires and them not fitting....

Heres how it currently sits.

245/40 is oddly tall, why are you choosing that size?

The Roads in Montreal are terrible, figured id stick close to OEM as far as sidewall is concerned

245/35/19 is sticking closer to OEM. a 40 series sidewall will be much taller than OEM.

Took some closer pictures of the front clearance... theres really not much space... do you guys think i should stick to stock at this point?

Are you running spacers? Hard to tell from those pics. If you are, you could remove them if you have clearance issues. Those tires should fit fine.

No spacers

245 35 / 275 30 or 285 if you have the wider stock wheels

I have swift springs and just put 265/35's on the rear (2012+ rims) - heaps of room left!

Your front clearance is low because of the taller 225/45. Why did the po install lowering springs with a taller front tire if the roads are that bad??

I would replace the tires with stock sized ones (225/40 & 255/35).

alex2192

As far as the front is concerned i dont think i have much options. will put 225-40 but the rear ill try 275-35.. hopefully i wont have issues. if you guys have any suggestions to a better setup please let me know.

You can get the right size stock tires or upsize . I'm lowered with 245 35 without any problems like many on here.

Would you mind posting a picture of the clearance on the front? Curious how close you come to the nut holding the wheel well

To resolve your issue, locate a tire size calculator and take a few minutes to review it.

I found a good one @ Discounttire.com (sorry for not indicating an actual link).

Your tires are pretty close to the fenders. I'd get OEM tires and (possibly) raise the car a bit. Get some C/O if you can.
