The correct tire size for my 22 F150 is 275/60R20. I ordered new tires from Amazon. I ordered LT's because I pull a 5th wheel. But, when I did the search on Amazon, they slipped a LT265 into the list, and I didn't notice until after I received the tires. So now I have 4 LT265/60R20's on hand. Should I bite the bullet and pay the shipping to send these back? Or will it be alright to run one size narrower on my truck?
