Tire size

I need new tires for my F250 4x4 PSD. Factory size is 235/85/16. Should I stick with this size or would a slightly bigger tire give me better mileage, i.e. less rpms?

Thanks, Chad

I would stick with the original size (check sticker on door frame). Wider tires will of course get you worse mileage, but if you go off road may help there. Taller tires will give you false m.p.h./miles on the odometer.

You may appear to get better mpg with larger tires but you'd have to recallibrate your odometer to know for sure. Also, consider that you are spinning a larger mass with a larger tire so stop and go driving will take a bite out of your pump budget

Depends on what you're going to do with the truck? Is it highway use?.....Do you expect to do more off-roading?......Time in the sand, which would demand a wider footprint?......Regularly carrying a heavy load, which would demand a higher "E" load rating?......I'm guessing in your original post mentioning mileage that highway use is your primary concern, in which case the factory size is probably best.

My stock size on the sticker said 265's not 235's.
I am looking at tired soon, but will probably go with teh same 265 or even go 245's cause we get snow and they seem to do better in the snow. the wider they are they seem to float more.

Happy shopping

265/75/r16 is whats on my sticker i believe. though the tires on my truck are 245/75/r16's
that wouldnt effect the mph would it?

also would tire pressure effect much of the mph? like having more tire pressure in the tire, would that throw off the mph accurisy on the gauge, compaired to actual truck speed?

am i making sens?

that tire you have seems smaller than stock for a 4x4
I had 265/70R16 Firestone Steeltex when I got my truck last year
I immediately put some 306/70R16 Nitto Terra Grapplers on it and was very happy with them. I have since upgraded to 315/70R17 BFG AT ko's and I did it with no fitment issues at all.
good luck
It all depends on what style of tire you want vs type of driving you will be doing.

How did the Grapplers hold up to milage? I'm on my third set of tires in 120K. Surpisingly, the ones that have held up the best were cheap Coopers. BFGs wore out quick on my truck (could be my heavy size 13).
Need something good in sand and snow.

Ditto, unless you need swampers or crawlers, stick with stock for best mpg.
Mine are 265/75/R16

I believe this is the stock tire for our rides, sans duallies. I have 285s and they are spot on radar tested as for MPH. The rest, I'm not too concerned with. They look good and get fair mileage.

I like the way the 285 and 305s look. However, when I put the new tires on my truck I had this crazy idea that I was going to keep the truck as close to stock as possible. Wonder what happened to that?

Toyo Open Country Mud Terrain. 285.

I researched the bajeebees out of tires about 12 months ago. I have a F350, 4x4 cc. I do a lot of mountain snow driving, plus off road in pretty harsh conditions.

My previous Baja All Terrains sucked in wet road conditions, which promted me to look for a better tire, with an E rating, due to the size of my mule and its towing needs.

Anyways within about two weeks of putting these tires on I got to try them first hand in 2-3" feet of snow. It was like having tiger claws under the body.

My next trip was on Military business which required me to drive 150 miles in a full on snow storm, on a unplowed, icy highway. Tires worked like a champ. I have about 30,000 miles on them already and there about 1/2 to 3/4 worn, but plenty of life still in them. Did some off roading this past summer and they were great. Beauty is as they wear, they stay as quit as if they were just installed, not like other name brands that increase in decibal levels as they wear down.

Hi Guys,
I also went with the Toyo's 285's on my f250 01 cc lbed 4x and my f350 cc lbed drw 4x and both gave me 1-2 mpg better milage. It was a good choise for me, I drive a lot of highway miles. I put 20k on the 250 and they still had nubs and showed almost no wear. I am at 15k on the 350 and ready the second rotation. Still looking very good.
I hit FTE almost every day and never have much to offer, I hope this helps. I learn something every time....
