If it came with run-flats, it has to go back with them and they need more than 3/32nds at the shallowest spot. I went through three sets of tires in my lease, the last set were used from ebay (went from dunlop to bridgestones) and had about 6/32nds, full of patches and howled like a wolf at the moon, but they were just for turn in. They won't care about brand, just need to be four matching tires (brand) and RFT if it came with them.

My co-worker took the initiative (after watching me) to replace his first set just as they hit 5/32nds and saved them for turn in, sounds like you're past that point, but i think i spent $600 for four tires installed (used) for turn in.

Maybe you can replace the bad OEM ones with used from ebay and save the good ones on the truck for turn in, buy yourself whatever you want now and enjoy and throw the originals back on to turn it in.
