    Hey everyone
    Just recently purchased wildpeaks at3 SL 265 75 16, they look fantastic , but here's the deal. Before these with my stocks, I never noticed the tranny hunting for gears much, and was averaging 20-21 mixed mpg. Now my tyranny is hunting around quite a bit, I feel like I'm now experiencing the issues others complained about, definitely down shifting much more. Also, mpg seems to have a significant drop, approx 3-3.5 mpg mixed (i'm gonna run a few tanks and see what happens over a longer period before getting discouraged) . I was hoping with going to an SL tire I would avoid these issues w the lighter tire vs E load. Any personal experiences to share?
    Thanks

    Also, what would you all reccomend for psi? I'm at 33/34, gonna take it up to 37 and see how this helps.

    I have the 4 ply’s in the same size and if I cant notice any drivability difference besides the speedo being slightly off. I also have the MT though. Remember that your fuel calculations are going to be a little skewed if you are going off of what the computer is telling you. You will be getting slightly better than what is displayed

    Although tire weight does have some affect on transmission. Tire "size" has the biggest over all affect on shift points. Lift and bigger tires look cool. And will definitely improve your off-road performance. But you will pay the price in fuel economy.

    Higher PSI will somewhat decrease your rolling resistance. But your shift points will still be determined from your gear ratio (including tire size). You may also experience a rougher ride.

    It's the e rated tire I think is the main contributing factor to the fuel mileage.

    The 10 ply are definitely heavy. But, from my experience with a Jeep, the only difference between E's & C's was - The C's were a little more pavement friendly.

    I'm running the same P rated tire at 35psi.Not much noticeable difference in ride or mileage.

    I did the stock OR tire for a 6 months then went to the tire you mentioned. I did not notice more gear hunting (it wasn’t great before, but didn’t get worse). I did notice an mpg drop of about 0.5-1 mpg.

    Changing tire size will have an affect on the gearing. You should be able to see this reflected in the RPM's when driving down the road. This will have a cascading affect across your transmission shift points and fuel economy. How bad of a Hit you take will depend on your driving habits and how large / heavy of tire you change to. But it will change.

    this tire also comes in a P rating. It is more than enough for a truck this light , the tire is lighter and rides alot smoother...

    Thanks for the input everyone I'll give it a few tanks and see how it goes. I have been tracking mpg since I've owned it, (2500 miles lol), and see what happens overall. The gear hunting is def more prominent bc before the tires I felt like I lucked out and didn't have the same issue so many people were talking about. Irregardless, I love the tire and can't wait to get it off road.

    My mistake. I don't know why the gear hunting. I'm on 265/70/17 Toyo open country at2 sl rated and no issues. Gas mileage is the same overall. No gear hunting issues either. Look again and see if the made a mistake and put e rated on there, just a thought.

    Is your truck an SR5? You’ll notice a pretty big difference if that’s the case. My personal truck is an OR And my company truck is an SR5. I have 265/75/16’s on my personal truck and while I only lost 1-2MPG with the bigger tires, the SR5 with stock size tires easily pulls 20-22MPG compared to the 16-17 my truck gets.

    I do have an sr5. What would cause a difference between the two?

    absolutely nothing. It is the same drivetrain, same weight, same everything. I eschewed the stockers on my sport for 17" Stealth6s and 265/70/17 Duratracs, my mileage took no hit.

    Bumping your psi up to 38 or 39 could help. I have 10 ply 285/75/16 that I run around 38 to 39 PSI and get 17 to 18 MPG all day. I definitely notice the added weight, but it’s worth it to me
