Tire real width on 17x9 +40 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

AndMsc · 09-01-2021, 12:08 PM

Hello,

I'm planning on buying 4x 17x9 5x100 +40 949Racing 6UL wheels. With them, I am planning on buying some 245/40 tires. But AFAIK, there is not a lot of space between the suspension and tires.

I was thinking about Michelin Pilot Sport 4 or Goodyear Eagle F1 Asymmetric 5. Which one do you think that has a narrower inflated width (more suspension clearance)?
And Goodyear has XL/SL tire in that size. Which one would you choose?
The thing is.. some tires have rim protection and that might scrub.

Do you have other tire proposals?

Thank you,
Andrei

Are you using camber bolts? If not you're probably fine, but might want to get a pair (or 4) of 3mm spacers if you need clearance. I wouldn't want to let actual tire width vs. a given size dictate what specific tire I was able to run...

AndMsc · 09-01-2021, 12:40 PM

I do not have camber bolts. Just PP suspension and PP brakes.

Here is how much clearance I had on stock suspension with camber plates, camber bolts, and -3.5 front running 6UL's 17x9 +40 with Maxxis Victra VR1 255/40/17. You should be fine with 245/40 or, like ZDan said, you can always run mild spacers.

AndMsc · 09-01-2021, 01:16 PM

Thank you. But the thing is, your tires don't seem to have much rim protection. Idk how much the michelin and goodyears stick out of the rim towards the suspension.

Did you take that on track at all? Any rub under hard cornering?

Code Monkey · 09-01-2021, 03:40 PM

A little bit of rubbing on the liners and frame. Got new liners and spacers to install and will report in a few weeks in my build thread.

Do you think that the 2 tires I mentioned above have a wider rim protection than yours? I try to figure out if it will rub more than yours, or the same.

Plenty of room with stock camber or race camber. We run 255/40 on that wheel. You can run our camber plates or just use camber bolts (small diameter strut bolts) to get more camber. Don't need to touch the fenders. That wheel was designed specifically for the 86. Out of production since 2017 though so I'm not sure you'll find any.

I will cry if I do not find any

AndMsc · 09-04-2021, 05:55 PM

Do you think 235/45/17 Goodyear Eagle F1 asymmetric f1 5 would be too stretched on these? (I know that in theory 9' wheel accepts 235-265 safe, with 245 and 255 being ideal)

If you think that they will be too stretched, I will get 245/40/17.

Thank you in advance

I did it! Found some �� Kinda panicked when you said I might not find any

Now I just gotta see if I buy 235/45 or 245/40

Just want to add that if you go to tiresize.com, you can directly compare tire information based on make/model/size.

Once you're on the site, scroll down a little and select the brand. Then model, and look for the size. First stat listed to the right of the size is the actual diameter of that specific tire
