2013 F150 New Tire Suggestions - Looking at Michelin

Looking for better MPG, I upgraded to Michelin LT265/75R16, the largest size my Tundra can wear.
They have better traction than any tire I've used, including the stock size Michelin.
And I got 186,000 miles without getting to the wear bars.
Do not get them if you want a mushy ride, they are real truck tires.
Tread Plies: 2 Polyester + 1 Polyamide + 2 Steel.
Sidewall Plies: 2 Polyester

If it was my truck I would look at the Alternate sizes that offer an LT tire. I ran LT285/55R20 hankooks when I had my F150 (sold to father in law) and they lasted about 75000kms before my father in law changed them out, he’s now running LT275/65R20 Michelin LTX A/T2 tires on it and is a very happy camper.

Many options in alternate sizes in LT configurations, just not the factory 275/55R20. Your truck stock will have zero issues going to a 33-34.5” tall tire with regards to rubbing or really hurting performance but keep in mind that the larger the tire the more effect it will have on your effective gear ratio.

My vote is for the Michelin A/T2 in LT285/55R20, close to your stock size and it’s a very good highway tire that still offers reasonable performance off the beaten path.

Other options?
My tire shopping routine is typically in this order.
Craigslist first, to see if I can get some good tires on the cheap. This works less in recent years because more people think used = new because they all think they're Richard Rawlings on Fast n loud!
2nd Amazon. Good tire deals to be had there sometimes.
3rd online suppliers like Tire rack, etc and see if I can get a comparable deal from a tire chain.
4th. Go to the tire shop, give them a credit card for my favorite tire. Typically only do this with company vehicles becasue it's usually the most costly.

I will never buy tires at Costco becasue they will only install stock size. So they don't get my business for anything but brisket, whiskey, TVs and sometimes motor oil!

I did end up getting the Michelin Defender LTX M/S.

Put 400 km on the weekend. Really happy with the performance so far, especially at higher speeds. Eliminated the "mushy" feel at 110 km/h.
