18x8.5/18x9.5 255-225 or 265-235? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hi, I've been doing some research on what tire I should choose for a while now, but I still have a few questions I can't find a clear answer for.

I'll be running 18x8.5 (front) and 18x9.5 (rear). I can't decide if I should use 255/35 and 225/40 or 265/35 with 235/40.

- I do not want a stretch tire or very little as I am still on stock suspension and i think it would look weird. Will 225 and 255 look too stretch? I'm less worried for the 255 than the 225 as it seems that the 225 is the minimal recommended size of a 8.5 wheel and 255 a recommended size for 9.5(If you guys can give me any clear picture can't find one anywhere with the right angle..)

- The 255 setup is about 1.5% bigger from am and the 265 3%. Is it something to consider or both are minimal and won't hurt anything?

-I also see a lot of people run 235 (3% dif. with oem) with 255 (1.5% dif. with oem) shouldn't the wheel have the same circumference or as close as possible without going too far from Oem specs?

-Lastly, I'll be running FireStone FireHawk Indy 500 at least that's what I'm currently considering. I can't find if those tires are larger than other tire in the same size like ''Michelin Pilot Super Sports''. Which would help with less stretch with the smaller size.

Thanks for your help!

I got the same size wheels this week. Let me know what size you decide on. I didn't buy tires for mine because I can't find a solid thread that has the same set up. If anyone can point us in the right direction let us know!

I actually bought the tire today should get them installed tomorrow, I went with 225/40 and 255/35 to keep the ratio as close as OEM, I'll take pictures of the streets (Good ones), but I won't have my car for at least 2 weeks since its in storage, I'll still post pictures with Stock suspension if it helps once i get it.

Here are a few pictures I took from the stretch on both size wheels. The strech isn't that bad if at all. If you want bubbly tire, perfectly ''square/flush with the wheel look'' or if you want to protect the lip from hitting a curb ''if you ever do so'' get a larger tire. Both 225/40 and 255/35 are more ''rounded towards the inside'' then stretched.

I'm really happy with the outcome, now only waiting to get the car out of storage! I think fitment will be perfect, even with stock suspension, will update when I get a chance

Thanks, hope it helps! if you have any question, feel free to ask!
