Help with Tire/Wheel fitment - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Perseus0001 · 03-15-2022, 08:46 AM

So I picked up my 22 WRB BRZ Limited back in Dec. and I have been mostly lurking around on the forums, living vicariously through the modification everyone else has been posting.

Because I live in NW Ohio, I threw snow tires on my factory 18" rims during the first week of ownership, specifically 205/40 Vredestein Wintrac Pro's. I have since spent the last several months trying to figure out what I am going to do for summer wheels/tires. In the end I decided to wait until Titan 7, Apex, or one of several other brands come out with some 18x9 rims with some decent concavity, as I have no interest in shaving, pulling, or rolling my fenders, or running silly camber.

So to get to the point I ordered a set of SSR GTX04 rims in 18x8.5 to hold me over, and I am expecting them to arrive at the shop in another few weeks...just about when it will be warm enough to throw on some summer tires. But I am not sure what size summer tires would look best on the rims??

I love the way the 205/40 Vredestein Wintrac Pro's fit on the factory 7.5" wheels, pictured below. Is there anyway for me to know what size PS4's would give me a similar look on 8.5" wheels? My gut instinct was to order 245/35's so the spedo runs correctly, but I was worried they would look a bit "chunky" compared to the look I have going now...

I don't have a lot of experience fitting wheels/tires, so I was hoping to default to the collective wisdom of the group.

Thanks in advance.

Your best bet would be to check the first gen wheel threads for pictures since every tire brand is slightly different.

245/35 is definitely a good size for 8.5" wheels. That's what I have on my wheels that I used for the first gen and they look good. Just waiting for spring to get them on the BRZ.

In my limited experience with Michelins, they run/look narrower than many other tires with the same size specs.

I'd say 235/35 would be the safe bet, and even a 225/35 would likely look fine (just a small amount of stretch).

I reckon 245/35 would be quite similar to what you have, possibly a little more square. I have 255/35s on my 8.5s and it’s pretty much square.

Apex makes an 18x9 et35 in their EC7R: https://www.apexraceparts.com/shop-b...brz-wheel.html

Yea, I talked with Apex, and they don’t really have anything that fits the stock gen 2 suspension right now with out running spacers, extra camber, or both.

Ohhh, that's right. I forgot about the suspension issue. They're so damn pretty though...
