33x12.50 R16.5 too big for my 99?

I found a good deal for some wheels and tires online and was wondering if they would work for what I am trying to do.

My truck is a 99 single cab with a 2.7L engine. I am wondering if I could fit 33x12.50 R16.5 tires on it and if I'd have enough power to turn those big boys and able to turn without grazing my fenders.

The wheels were on a half ton suburban, 6-139 lugs. I think they will go on my hubs.

I have an 01 2.7l that im running 33x12.5's on my stock 15's and there's no problems with power. I did put spidertrax spacers on so I wouldn't rub but I did have to trim a very small section of plastic that didn't even matter.
