I recently bought a 2015 F150 XLT and I'm looking at putting on some all terrain / all weather tires that are the same size I currently have on it now (256/60/18). I understand that the tire will be heavier and will result in lower gas milage, but should I expect a significant reduction if I'm sticking with the same size and not leveling it? Also, should I expect some rubbing under the same conditions (same size, no level)?

I live in San Diego where we have desert and mountain conditions w/in the county, and although I won't be doing any major off roading I do anticipate winter conditions in the mountains and dirt roads/light trails in the desert or here in town and I'm just looking for some extra protection that the highway tires don't give - without breaking the bank, having to lift/level it or significantly decreasing MPG.

I'm looking at getting the Hancook Dynapro ATM RF10 or the Falken WiIldpeak A/T3W both 265 / 60 R18.

I included a pic of my truck (below) to get an idea of my current setup - any advice would be greatly appreciated!

If the stock tires don't run, AT's the same size won't either. You will see 1-2 MPG hit due to the weight of the new tire compared to stock. When looking for AT tires, pay attention to the weight. I went up 1 size from 275/55/20 to 285/55/20. But went from a 39lb tire to a 61lb tire. I lost 1 MPG

I would imagine no rubbing would occur with an AT tire in the same size you currently have, so long as you currently do not have any rubbing issues. If you go with an All-Terrain 265/60R18 they should be similar in weight to your current tires, thus not effecting MPG too terribly much I wouldn't think. It looks like the Hankook's weigh 39 lbs. each vs the Falken's which are 43 lbs. each. The Falkens do however have a slightly higher treadwear rating I believe. I would say you could not go wrong with either tire.

If you decide to run a different size tire and it's an LT tire, that's where you run into a much greater MPG loss because LT tires are typically heavier (sometimes 10-20 lbs. more each.).

Thanks for all the advice. I decided to go with the same size Hankook Dynapro AT tires. I'm stoked with the more aggressive look while not altering the rest of the truck. Thanks Again!

Unless you go crazy with an aggressive mud tire in an "E" rated tire that is 2-3" taller than stock I doubt you will see a measurable difference in fuel mileage. Even at that you'll only lose 1-2 mpg. Stay with a P rated tire with an all terrain tread and you'll be fine. Which is what you have done. Good choice.

You can go up to 34'' with no rubbing on stock setup... However, if you go too wide in order to achieve the diameter, you might get some rubbing on the control arms.

I bought a set of Wildpeaks (P-rated) just before winter and I love them! No noise at all as compared to the OEM tires, better traction in winter (3PMSF) and aggressive look. The 55k threadwear warranty is also interesting. Very happy with the buy.

My OEM tires were Dynapros and I didn't like them - they didn't look aggressive at all and were slippery on wet roads. Perhaps the 3PMSF ones are better. OEM tires are always cheap...

I ordered the Wildpeaks but discount tire ordered the wrong size and gave me a deal on the AT-Ms. They have served well so far in the dirt (no mud). They are kinda loud on the highway but they are an AT tire. I'm satisfied.

I know you made your decision, but for anyone else that finds this thread searching I've been impressed with the Michelin LTX A/T. They don't look as "cool" as other A/T tires, but they must have incredibly low rolling resistance, on my last truck I picked up a full 1 mpg when switching from the Pirelli Scorpions .
