I know this question has been asked a ton but can't seem to find my answer on here. I just bought a 2014 f150 XLT ecoboost it comes with 235/70-17 on it which to me don't do the truck any justice so I believe I should be able to fit 285/70-17 with no lift or level but I'm not sure wanted to use nitto trail grapplers. Also I plan on getting getting a set of 18" rims too but later so I wanted to know the max 18 size also on a stock truck without a lift or level. I would post pics of it but can't figure out how to from my phone.

 

I think a 285-70-17 will be a pretty aggressive fitment, depending on what wheel you go with.

A 285/70/17 is roughly a 32.8" tall tire and depending on the tire, is roughly 11.5" wide (per section width)

A 275/65/18 will be roughly 32" tall and appear much more aggressive and still be a good fit without a lift.

 

Great Thread. I'm too in the market for my 2011 F-150 5.0 litre. Currently has slippery Hancooks P235/75R17 108S tires. Looking at 265/70R17 tires. Suggestions? Dealer suggested Bridgestone Dueler AT Revo 2 but one negative review on Tirerack re winter driving. Live in Ohio so traction is primary concern. Cost & treadwear are distant concerns. Want excellent wet traction as well aggressive look.

 

Welcome to the board.

Michelin Latitude or Firestone Winterforce are few good options you got. But if you are riding other trails than snow, the best option is Bridgestone Blizzaks ( compare their variety here: Bridgestone Tires ), will outperform other snow/all-terrain tires.

 

I do have a friend who has 285/65-18 on a stock 2010 super crew xlt with the stock ford 18" rims so I might just go with those

I know there will be some disagreement on this, but most all-terrain tires aren't that great in snow. All terrain tires are designed to wick away mud and winter traction needs something to grab to. Two different tire concepts.

That said, some LT rated all-terrain tires do have the severe snow duty rating on the sidewall, which indicates they are rated for severe snow use. The tread design and compound will slightly differ from the Euro/P-metric tire. One thing to consider, an LT tire will ride horrible on a 1/2 ton truck, like an F-150. LT tires are built for 3/4 and 1 ton trucks.

If the look of an all-terrain tire is what you are after, know that you will give up some of the things you are asking a tire to do. The Michelin LTX AT2 is a very mild all-terrain tire and what I would suggest to you.

My personal thought, for tire longevity, wet weather and cold weather traction, you would be better off with a tire like a Bridgestone Dueler HL Alenza Plus or a Michelin LTX MS2. Both are fantastic but the Michelin does have a proven track record behind it where the Bridgestone is stepping out on a new limb, replacing the Bridgestone Dueler HL Alenza.

If cost isnt a concern then why not find the rim tire summer setup you want and convert your stock wheels to an exclusive winter tire like the blizzaks?

Also, if you are changing tire size, you need to consider a tire size calibration either through the limited options at your dealer or buying and using a programmer. Think custom tunes here while you are at it. spend a few hours in the tuner section and you will be able to decide for yourself.

 

Both the 285x70x17 and the 285x65x18 would be the max size on a stock height 4x4 using the OEM wheels. Just be prepared to take a small hit in the mpg's and performance by going to a taller and heavier tire.

 

Just my opinion but if you go with 18's then id do 275/65/18.. I have them on my 2wd and the size looks good.. Doesnt look small and doesnt look stuffed

 

AJ,

I really appreciate the suggestions. I could read opinions and reviews for hours and not garner the level of insight that you provided. Really helpful.

At this time I am not lifting the truck or changing the rims. One last question:
Is 265 the maximum width you'd recommend? I like the more beefy look of a wider tire. I've seen F-150's with 305's on 18" rims without lifting.

Thoughts?

 

Are we keeping factory 17" wheels?

I am not real sure what the factory rim width is. If it is 7", which it probably is, the largest I can recommend is a 265/70/17 without any rubbing or speedo/gearing issues. That will be about an inch and a half section width wider and just under an inch taller, which will give you the beefier look that you are after.

A 305 x 18 might 'fit' but not without some sort of rubbing somewhere. I would have to turn you to back to the forums for aggressive fitment information like that. The fitment information I have is from our engineers who have measured the vehicle and give us information to make recommendations. Our information is based on factory height and 305 is far outside of that recommendation.

All standard 2004-up F150 wheels are as follows

17" 7.5" wide
18" 7.5" wide
20" 8.5" wide

Raptor wheels are the exception, early ones were 17 x 10, new ones are 17 x 8.5

 

Thank you for that info-
