I've seen this question asked several times over the years, but never seen a definitive answer. I'm hoping that new user "FordService" will see this post and be able to determine the answer.

I bought a new 2012 F150 Lariat with 4x4, the offroad package and P275/65R18 114T tires to be my all-season and (reasonably) all-terrain vehicle.

I was dismayed to find on page 262 of the owner guide that it said "Do not place chains on the following tires sizes: ... P275/65R18 ..."

I'd really like to know why chains aren't allowed with this tire, and if there's anything I can do, or changes I can make, so that I can use snow chains on this truck.

Thank you for any assistance you can provide.

does that include cables or just chains?

That's.... interesting. The likely culprit is due to the reduced clearance on the tire and the "slop" expected with chains it would tear a fender liner out.

That being said, if you've ever installed chains properly you know how to adjust for slack and keep things tight.

Full disclosure: I run a set of singles on my XLT, however it is only on 17" rims...

I too would like to know and posted such here

It seems ludicrous to have a stock 4x4 in which chains aren't recommended. The only possible reasoning I can see behind this is to keep the truck 'lower' for better fuel mileage ratings, but to me it's extremely frustrating. Had I known that upfront I would have bought a stock model that I could put chains on. Granted did it anyway, but still I bought this truck to use off road and in snow and ice...

They don't reccomend it but chains are available for that tire size. Check laclede chain company.

Most likely it was a clearance issue as mentioned with fender liner, brake hose etc but if you have proper chain tensioned and don't go over 25-30 with chains you should be fine
