largest tire size 1/2 ton 4wd fleetside, photos??

[hoovers71]

wondering what a good sized tire upgrade would be for my stock 71 1/2 ton 4wd.

I will be using it for mild trail and road driving mostly. Would like a more aggressive look than stock.

31x10.5o r15 is what I had in mind. Can I get away with 32 without rubbing, or even the 31's for that matter?

I know this has been rehashed in several posts, none seem to have a clear answer.

Photos would be great too.

Thanks
