18" Limited OEM Wheels - Tire Question

I apologize if this isn't posted in the correct forum. I have a question about what size tires I can fit without having to use a wheel spacer.

I have a 2013 Limited Tacoma with a leveling lift. It has the chrome clad 18x7.5 limited wheels. I understand a 275/65-18 is the widest I can go due to the wheel only being 7.5" wide. What I can't find through searching is whether or not this size would rub the UCA with the factory wheel offset. I've seen some guys running this size, but they also had spidertrax spacers. I couldn't figure out how to send them a direct message, so I'm trying this route.

Does anyone have the OEM 18" chrome clad wheels (stock suspension or leveled) have this tire size? Does it work? Or should I go 265/70 or 265/75 maybe?

I have now. Thanks!

Still looking for some confirmation, if anyone is running a similar setup!
