I own a 2015 is250 awd f sport , I'm going to be buying 19x8.5 +35 F and 19x9.5 +38 R wheels , my question is what tire sizes with no fender mods or camber , the car will be dropped on rsr down springs , would work with my car with no rubbing thanks in advance

 

Your thread is related to mine. Only difference - I'm going for 20s. I've seen other 3IS owners running 19s on 235/35-19 & 265/30-19. They were also lowered.

 

+1 I'm getting some similar spec wheels, and the research I've done has shown a lot guys going with 235/35/19 up front and 265/30/19 rear.

 

My fear is the rear with 265 and having rubbing issues with passengers , maybe a 255/30?

 

The 255 would be a safer bet yes. It would just be a slight stretch.
Actually maybe I should have went with 255's on Michelin Pilot Super Sports... those are actually pretty square/thick, so I may rub on my 9.5 +39 rears lol.

Oh well my wheel set should be in sometime next week I'm hoping, so I'll report back

 

Please do thanks

 

im running the 265 in the rear I went over a speed bump and I heard rubbing noise in the rear......

 

"they are made by MRR gf9 front are 19x8.5 and rear are 19x9.5 offset 35front 40 rear no rubbing issues......"

You previously mentioned that you didn't have any rubbing issues. What do you think is the culprit for the rubbing that's occuring now? Is your setup still 19x9.5 et 40 with 265 in the rear with RSR half down springs? I don't have first-hand experience with the various setups, but from what I've been reading, I'm surprised that even with a combination of a non-aggressive offset and mild drop, you would still be susceptible to rubbing.

 

19x9.5 et38 with 265/30 Hankook V12

Slight rub entering gas stations and big dips. Luckily I'm on coilovers and I can raise the car a quarter inch to solve the issue.

 

Update:
Got my wheels on today 19 x 9.5 +39 with Michelin Pilot Super Sports 265/30/19

The driver side rear rubs a bit on dips and inclines. The passenger side rear hardly rubs at all oddly.

Might be an alignment issue, I'll have to get that checked out soon.

It has been super rainy today so I didn't get pics

 

255/30/20 in the rear will be the best option. i already have it installed and the ride is smooth plus no rubbing, the view from the back is amazing but the view from the side is even better cuz the rim is a bit outward than the tire which makes it look more filthy(in a good way)

 

Interesting. I'm now debating between 19's and 20's. We'll see... Stay tuned!

 

I ended up buying different wheels , Vossen CVT 19x8.5 +32 19x10 +42 tires 235/35 and 255/30, will post pics soon I just received them
