You don't mention if your truck is dropped or what wheels but here is my $0.02 worth.

I don't have exactly the same but... 72 C10 swb - Front 275/45/20 rear 275/60/20. The front is dropped about 4" and the rear dropped about 6". Wheels are 20X9 with a 4.75" backspace. The bed is tubbed. The only issue I have with this size is when going down the highway and hitting a dip, the right front tire will scrape a little. But the front springs are weak. With full wheel lock left to right, no scraping. Tires fit within the fenders. Fenders cover about 2" of the top of the tire front and rear.

Overall it looks pretty good but as always, there are improvements to be made, so I am starting a suspension rebuild. The front will be dropped 2" and the rear 3". If the measurements are correct, the fenders will be above the tires by 1" front and 2" rear.

I would post a couple pictures but I am computer challenged and my son is tied up.
