Been reading around for a while and I'm pulling the trigger on new tires.

I have a 2015 XLT Sport Supercrew with the 2.7L Ecoboost. One thing to not is I commute a lot for work. For those of you who have swapped from the 275/55r20's to the 275/60r20's how much gas mileage did you end up losing? If it's not going to affect it all that much I'll get the 60's but if it isn't worth it for an inch more of tire I'll stick with the stock size.

let me know what you guys think! Help me decide as I'll be pulling the trigger tomorrow morning as I'm on a time crunch lol.

I switched from the stock 275/55's to 275/65's last week and I loved the look, but was not a fan of the power loss on my 3.5EB with 3.55's. I ended up having the stock tires put back on today. It definitely looked better with the KO2's but I commute in mine as well so decided the comfortable ride with power is more important to me that looking cool. I'm sure it won't be as much of a difference with the 275/60's but my advice is if you commute, leave the stockers on there.

Should have gotten a tune, with 275/65s I have more power than stock and get 19mpg....

That's what a few people told me, but I had a bad experience with a tune back when I had a VW GTI so I'm kinda paranoid about warranty issues now.

Look at the weight difference, KO2's weight a lot more. More weight means less mpg.

I put K02 on 1600 miles ago. I think towing might be 1 mpg lower, maybe but around town I continue to get 16 to 17.5, but that all depends on SPORT mode. NOTE: Only use sport mode if you like meeting gas station attendants.

You can't change physics......lot of people try.

I have been playing around with this - Hankook's are 41 pounds, I weighed the tire and wheel, I kept getting 80 to 81 pounds.

So basically the wheels are 40 pounds

I thought about going to an aftermarket wheel that weighs 36 pounds, while its not a lot I would gain some of that weight back.

So stock is 81 - new wheels with 60's would be 91, and 65's would be 93 pounds.

I have a 3.55 V8

Not totally decided yet, still kicking around the idea.
