Biggest tire size for stock 20" Chrome Denali Wheels?

[TL24]

I'll be picking up my 2004 Denali this weekend and it needs new tires. I know the stock tire size on these Denali's with the chrome 20" wheels is 275/55R/20 if I'm correct, my question is this: what's the max size that I can slap on these wheels without needing to modify anything?

I'm looking to pick up some Nitto - Terra Grappler so everyone's input would be greatly appreciated!

285/50/20 is wider but thiner

305/50/20 fits but with lots of rubbing I believe so that won't work

Thanks, I think I'll go with the 285/50/20's - what do you all think? Anyone have pictures of them on your oem Denali wheels??

So 285/50/20 is the most u can go without any modifications?

Can it be any more than 50 sidewall?

285/50/20 is the widest with no mods

275/55/20 is less wider but has a thicker sidewall

I'm currently running a 305 50 20 with no issues.

In the past I have run a 305 55 20 Toyo Open Country A/T with minimal rubbing
