275/65/R20's?

So I've got 35x12.50 Toyo MT's on a 20"x9" wheel on my truck right now and I've enjoyed them but it's time for some new tires. I want to go a little narrower (they slightly rub the leafs at full lock right) and change from the MT to an AT. My tire guy suggested the Toyo 275/65/R20 AT. Says it's a 34"x11" tire which sounds good, but I'm a little worried it might look a little narrow on a 9" wheel. I don't want them to look like pizza cutters. Is the 275/65/R20 the size that comes on the new trucks with 20" wheels? Anyone have any pictures of this size or maybe a touch wider?

Yes.

Your 35s are 13" overall width x 35" diameter.

The stock size 275/65R20E is 11" overall width x 34.5" diameter.

Toyo Open Country A/T has one that's 11.7" wide x 32.3" diameter(285/55R20E) and another one that's 12.6" wide x 34.3 diameter (305/60R20E). So the 305s would meet your requirement for "a little narrower" and the 285 would be right between the stock-size 275s and your current tires. BFGoodrich AllTerrain has one that's 285/65R20E, 11.5" x 34.7, which should be right down your alley.

So pick your poison. They will all fit just fine on 9" wide rims, per the tire maker's specs.

Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream.

I've got an 06 with factory 20s, and yes, it came with 275/65/20s. I recently went with Toyo MTs in the same size. They are a great tire, but I do think they are a little narrow for the truck (pizza cutters perhaps), but they don't rub. And the factory 20s are only 8" wide.

I know you said you want to go with an AT, but I've heard the Toyo ATs wear faster than the MTs. If you want to stay with the Toyo MTs, take a look at the 315/60/20s. They would be perfect on your 20x9s.

The Ford OEM 20" rims are 8" wide, so the stock-size tires are 8" wide at the bead, but 11" wide overall (at the sidewall).

I had the Toyo AT's a few years ago and liked them, but I do agree they wore a lot quicker than these MT's. Maybe thats because the tread on the MT's are so much deeper or maybe the AT's are softer I don't know. I've put about 45,000 on my MT's and probably could put another 10,000 on them. That's awesome life if you ask me, especially on a big chunky mud tire.

Smokey, you always have the answers. Thanks! I think I just need to see some pictures now. I'm not 100% sold on getting Toyo's but my Les Schwab has been awesome to work with in the 10 years I've been buying tires, brakes, etc from them. I would love to give them my business. What other brands are guys running in this general size? I had BFG AT's years ago and could never keep them balanced, so I'm a little leery looking at those.

Skanj0, you have any pic's?
