What is the biggest tires I can fit with stock suspension?

[HorizonsEdge]

I am looking at these wheels https://949racing.com/product/18x10-coto/
18x10 Coto 5x120 +48

On my stock 2025, my winter setup is DWS06+ 265/40/18 on Enkei ts7 18x9.5 which works great and no rubbing. My summer setup is stock wheels with Conti extreme sport 2; 265/35/19 which also clears nicely.

I just have no idea how to visualize the 18x10 but I expect that the answer can be provided.

Thanks in advance

It'll give you a good idea how to compare with stock. But won't tell you if it'll rub or not.

That said I swear I read somewhere someone found success running 305s... @iforgettopee was that you?

I could be off it's still early and coffee hasn't kicked in.

I fitted 275/35 Michelin tyres today on the stock 19" rims. No issues at all.

I created a (dormant for now) thread on this a while back.

Check it out.
I'm guessing that it may not be the direction you want to go. No idea why you wouldn't, Ha Ha!
I invite everyone to give it some love anyway, if you want, if just for the laughs.

So far the largest I have fit is 275/45 ZR18 on a MITA Motorsports 18X9.0 inch wheel with ET +45 offset.
The 45 sidewall is definitely a bit too tall, though, so next time around I'll be installing 275/40 ZR18 tires.

Happy hunting!
