Default F-150 Tire Sizes - UPDATED: finally made a decision and purchase

I have a 2013 F-150 XLT 4x4 5.0L I bought in December. It's your basic XLT with the go cart sized P235/75/17 Hankooks on it. I gotta ditch these things and get some LT tires. I will be buying a/t's since I do a lot of miles but still need to get around our farm and boat ramp. I know BFG A/T are very popular, but I've had them before was not too pleased. I do tow a decent amount, and will probably end up with a bigger boat while I still have this truck so I'm not wanting to go large enough to significantly impact my towing abilities.

I'm thinking of just going up the the equivalent stock size for the nicer trucks, which is 32-ish. For my 17" wheels that's a 275/70/17, but there's not exactly a lot of options in that size. My other thoughts are 265/75/17 (again not a ton of options) or 285/70/17 since there's tons to choose from, but it's also the biggest of the 3 I'm considering.

For tire brands I'm thinking Cooper AT3, Falken Wildpeak AT2, Nitto Terra Grapplers. Maybe a Duratrac but that's probably getting a little too agressive for 20k miles a year I've been averaging.

What size tire would you recommend putting on this rig?

I found a set of 20" rims on Craigslist that needed tires. They were asking $600.00 so I offered $300.00. Ended up getting the set for $350.00. I sold my 18" lariat rims with good Michelins for $750.00.

Put on the Nitto Terra Grapplers. Size 275/65/R20. It's a 34.5" tire. I did not have to lift, modify, cut, or do anything. No rub and the noise is minimal. I got 80,000 miles out of a previous set of the same tires on my other truck. They're 10ply tires I believe and I've been really, really pleased. On road, off road, sand, and wet traction are all good.

Your truck will handle a 35" tire with no problem.

If you're going to be towing a lot, its best to stay pretty close to the OE size in height (or diameter), larger tires have the effect of changing the final drive ratio in a direction (taller gearing) that is not good for towing or braking when towing either. That said, if you can get an XL rated tire (still a P tire but stiffer sidewall and better weight capacity) or a C rated LT tire in close to that size that would be the your best bet.

Looking at charts on the tire rack, this is a 30.9" tall tire. The tires in your OE size are all P rated.
However, if you can go to a 245/70-17, that is 30.6" tire but they can be found in LT versions that are E rated. This would be much stiffer than your typical P rated tire but much better for off road or towing. You will have to inflate them to higher pressures than the P rated tires that are OE because of the heavier construction. This size will give you want you want without creating other issues.

Thanks for the input.

I hear nothing but good things about the terra grapplers. I don't want to go as big as 34-35" for the reason LouC noted about affecting drive ratio. And I expect my next boat to be pushing the limits of the towing capacity.

Yes my stock tires come up just shy of 31". However, the same drivetrain in the nicer trims, lariat and FX4, have a stock tire size that's 32.x" according to sizing charts, hence my reason for thinking going up to 32" wouldn't be a noticeable difference. I think I want a little more width than 245. An I'm not concerned about a stiffer ride with D or E rated tires. Hate how mushy P tires feel on a full size truck, the main reason to ditch these before wearing them out.

Do not know if this helps, but these are Nitto 305/75 on stock 17 rims. They ate into my mileage some, but I like them.

Had 285 bfg at's for my last set on My F-150 on 20 inch wheels. put me in the camp of a bfg fan... I do a ton of highway driving and got close to 60k out of my bfg's by rotating and balancing every oil change and keeping alignment in check.

Have 305 Mickey Thompson ATZ's now. Great looking and off road tire, but not a good highway tire. I've gotten decent mileage out of them this far but road manners/ noise is not great for the 30,000 miles a year I average.

Have never owned terra grapplers but my best friend had them on his Ford. They were good highway tires and as decent off road as any at's can be (other than the Mickey Thompsons). Thinking hard about going with the nittos for my next set if I don't trade before then, from what I've seen the prices are pretty good.

After much shopping and pricing both a/t and m/t tires I've made a choice. The Discount Tire exclusive Cooper Discoverer ATP in LT265-70-17 load range E are getting mounted as I type. Slightly more aggressive than the AT3's. Tons of good siping should be great for ramps. 55,000 mile warranty, even for LT, but from the reviews I've read most seem to get more than that no problem. It's raining here today so it'll be a good day to test them out for rain. Glad to be dealing with Discount again, they're always so much more professional than any of the other tire chains in my experience.

I'll post a picture of them tonight.

Absolutely thrilled with them so far after day one. Went out to the shooting range and ran about 4-5 miles of dirt/clay/road base/gravel road just after some rain. They clean out that sticky red clay better than any other a/t I've ever had. No noticeable road noise at all. Still look a little small, but that's okay. I really didn't want to push it or give up anything on feeling any reduced power for towing.

You'll love those tires. I was a die hard at/bfg guy and the last set I had just didn't last. When I went to my tire guy, he suggested these as many others he sold bf's to were bitching about them because they are priced so high. He felt these were as good or better a tire and they are significantly cheaper and still USA made. I've had a set on an 03 silverado that I use extensively off road in the hills going to and from logging decks and they have left me very pleased. I'm at 38,000 and change and they have every bit of 50% tread left.

Had those Hankooks on my old 2011 truck and the tire guy punched the sidewall on the shovel machine when attempting to remount after a rim leak. They were so thin. It was my favorite truck ever with flawless performance except for those cheap thin tires. This is a great thread. I have 18 inch rims on my 2013, but this gave me some great insight into tire selection if I decide to tow a heavier boat. Enjoy! Thanks!

When you put larger tires on your truck won't you have to recal the speedo?
Shouldn't the gears in the rear be changed also?

Yes, it will throw the speedo off.

If you go big enough you'll need to regear. Not a big deal if staying fairly close to stock. Take a look at the variation in the stock tire sizes for the different trim levels with the same drivetrain. What I went to is still not as large a tire as some of the stock sizes for some trim levels.

It will change the effective drive ratio but only going up one or two sizes isn't a big deal, especially if you have one if the lower (higher numerically) geared rear ends available for your model. Where regearing really comes into play is when you put 37 inch swampers on a Toyota 4 cylinder that came with a low number rear end and 26 inch stock tires.

As for the speedo it does throw it off. Some vehicles have an actual speedo gear that you change out, most modern trucks you can reprogram the computer for tire size to adjust the speedo.

It has been my experience, through absolutely no scientific research, that Ford trucks speedos actually read a few mph slow from the factory.
