I am looking to get new tires for my F150. I called 2 local tire dealers to get a 275/70/18. I have a 2.5" leveling kit and a 1.5" rear block, so I wanted a slightly bigger tire then what I have on now which is a 275/65.
Both dealers told me all they could get in were 10ply Load E tires. They said not only will a 10 ply destroy my gas mileage because of the weight, but the ride will be absolutely terrible.
They said a 10ply is meant for F350 ranger and shouldn't be put on a F150 because it is not heavy enough.


Any of you guys running 10ply? Or what are my other options for getting a 33" tall tire not 10ply Load E

 

I am running 285/70/17 Nitto Crosstek HD's which are load range E's. I still get 16-17 highway. The ride in town if the road is rough kinda can be bumpy. No worse really though than my Escape was with 235/75/16 Dayton Timberline II's.

 

I don't know what those dealers were smoking. "F350 Ranger"? "Destroy" your gas mileage? "Absolutely terrible" ride?

I'd wager that most of the fellers that go up in tire size around here (which is most of the fellers on here with 4x4 trucks) are running a 10 ply/E load index tire. That's because most of the "bigger" tire sizes are 10 ply/E load index.

You will notice a decrease in fuel economy. Depending on what truck you have, the decrease will vary. In my '05, I lost about 2-2.5 mpg going from the stockers to a 35" tire. In my '12, I only noticed about a .5 mpg decrease going from the stockers to a 33" tire.

Ride quality is a very subjective issue. In my experience, going to a 10 ply tire definitely "stiffened" up the ride, but by absolutely NO means was it "absolutely terrible".

 

I'm running 305/65-17 BFG AT KO's on our Wrangler JKU and couldn't be happier. They are an E load range.

 

Maybe if you ran them at max psi they would ride terrible, but in the 40-45 range they should be fine. Have my d rated tires at 42 and they ride fine. Definitely heavier though.

 

LT 10 ply tires will ride a little rougher then P rated stock tires. The larger you go will also cause you to lose around 2 mpg on average. The advantages are is that you get a heavier duty tire that resist's flat's, gives you better traction and enables you to carry or tow heavy load's safely. In the all important look's dept. LT tires have it all over the P rated tires. I've been running LT rated tires for almost 40 yrs with no regret's!

 

i am running a 275/70/18 load range E mud tire. dropped about 1-2 mpgs but depending on how you drive that is easily made up. the ride isnt bad. i think what he meant is that they can be aired up to 50 psi which makes them stiff butttttt also increase mpgs. i run mine at 50 and the ride is still just fine. if you have any more questions feel free to pm me

 

I recently went to 275/70/18 BFG AT KO's from the stock P rated tires. Right away I noticed a little more road noise... not bad though. The ride may be a little rougher but not terrible. I definitely like the looks much better. I am currently running them at 45 psi. I haven't had them long enough to check my mpg yet. Good luck!

 

you should go to a different place. these dealers sound like bozos.

oaw

 

Also keep in mind gas mileage is not just lost due to added weight. A taller tire also changes the overall effective gear ratio of the vehicle.

 

I'm running LT245/75R16 10-ply tires on my truck, which is incidentally the factory size and only one load rating higher than indicated on the door sticker. I would say that whoever told you that yarn doesn't know what they're talking about!

 

I've run E range 275/70-18's in a variety of different tires on my current and last truck. The will make the ride a little rougher over the standard P-Metric tire, but not enough to really matter. You may find one brand tire offers a rougher ride then another. There is no appreciable difference in gas mileage going from the 275/65-18 to 275/70-18 or load rating.

You're tire dealers are telling you this not because they have no clue about the products they sell. They are used to folks who upgrade their comfy riding half ton to LT tires who end up complaining about ride and decreasing fuel mileage. In short they are playing devils advocates and are trying to make sure they aren't stuck with a lightly used set of E range tires, if you determine that you don't like them.

So, you don't need to go else where unless you don't think they are good tire shops.

Don't know where you live, but if it's NH. Send me a PM. I'd be happy to let you see what a 11 FX4 rides like with E range 275/70-18's. Maybe someone else on the site has a similar tire and lives near you. That's your best bet for finding out if you'll be happy.

 

Toyo Open Country Mud Terrains 33x12.5/20, LT rated load E, 10 ply. Had them almost 4yrs and 47,000 miles. Lost about 1.5mpg avg and the ride only stiffened a little bit at 45psi. Is it worth it? As far as these tires have lasted to, and as many painful pot holes as they have withstood and never resisted to puncture, nor even lose air, yes. I will run load E 10 plys again, from now on actually.

 

35/12.50/20 toyo m/t's here bead balanced and love the S&%T outta them babies! lil bumpy but no loss in mpg from my 315/75/16 mtr's that were d range i think the hold the road better!

 

have 275/70/18 bfg at tires and run at 50psi per bfg recomendation when i called. Have no issues at all they ride fine, they have a slight hum but any at or mt will do that from stock. The ride is fine, its a truck it doesnt ride like a caddy .
