    Yep, you can have your cake and eat it as well.... provided your a mall crawler. I got no where to go in the big city so yep, mall crawler here.
    I went Toyo AT3 based on review's.
    Tire weight is 46lbs, seven over stock dunlaps. I went FN rim that's 7 lbs less than orp rims = same weight.
    I never had a reason to clock my gps with the stock size so I have no idea if mpg was correct. The speedometer is spot on with the 285 at all speeds I checked up to 80. Used highway mph digital signs and gps for verification. That said I used to average 19mpg stock tire. The 285 P rated hand calc came in at 18.99 mpg. close enough in my book.

    That’s pretty impressive. I’m lucky to get 17 on stock pro wheels/stock size nitto grapplers

    I do drive conservative. The 20s have a dash gauge that shows mpg after each engine start. One day on the way to work I drove like I was 18 again and punched it all the way to work. That got me 14mpg

    I get 16.5MPG on 295/70/17 that weigh like 65lbs:cool: and that’s not even trying to drive conservatively. That’s what the display shows anyways, and that’s calibrated to the stock 265’s so I’m probably somewhere in the 17MPG territory if I really got technical. Been super happy the truck seems to do great in the heat!

    Looks great nice choice in tires, any lift on your 4Runner? I’d love some 285s on mine but can’t afford to lift it to fit me on LoL..

    Beautiful!! I have the same exact color 4Runner. Looking to do the same exact thing to mine.
    What lift did you go with? I also have the gunmetal TRD Pro rims. Is it safe to run the 285's on these or should I go with the FN's?
    Thanks in advance.

    Any 2.5/ 1 will do the same thing. On different rigs that I've had, fox 2, bilstien 6212s, Toyota pro fox, Halo lift formerly boss, eibach, rough country and only one I liked for ride quality is the OEM fox pro.
    I may try elka

    I ordered the Eibach lift a few weeks back. Still waiting. Just thinking about tire size now. For sure going with the Toyo's because of weight/mileage. Going to look up the lifts you listed.

    I'm getting 20.mpg city and 22 mpg highway with stock bridgestone dueler HT's on the SR5.
    I keep them at 36psi and drive conservative....must be the street tire tread and higher than recommended Psi ?

    I almost went with Toyo open country AT2 P285 as it only weighs around 46lbs, but I thought 285s would make my limited(full-time 4wd) even more sluggish due to the size and the amount of lift it requires, so I chose to go with 265 Falken which weighs roughly the same.

    Hmm, lol. wonder if thats why my mileage is the same. I had the 265 wildpeaks before these.
    By the way with my 19 and my 20 I lost zero mpg with leveling.

    Did you notice any power loss and lack of response when accelerating from a stop?

    No. I've been running sprint booster at red 5 on 3 different runners now, even enhances stock. Goes when you want it to and never worry about merging on Chicago move or die highway merge maneuver

    I get about the same with my 13 Trail with those same tires and a light foot. Mostly highway, and not too much stop and go around town. Not sure of city exactly, but I typically 20.5-21.5. I did a 350 mile highway trip a few weeks ago and got 22.9.

    I love this mileage, so I'm very picky right now while I'm shopping for tires. I'm liking what I'm seeing of these Toyos lately though.

    That low of a weight for a 33" tire concerns me. Generally, the heavier the tire, the stronger it is and more resistant to damage from rocks.

    I'm running the Goodyear Wrangler Authority tire and in stock size, it is one heavy tire. Reduced my gas mileage by about 1.5 mpg. It has been all over the woods on some pretty gnarly trails and never a concern and it wears like iron. Unfortunately, it has a very stiff rubber compound which is great for resisting tears and punctures and for long tread life, but makes it horrible on packed snow and ice. My rig was a bit scary in the snow last winter.

    I tried to find out the weight of the tires, but Goodyear doesn't reveal it on their website. Weird.

    I average 18.1 mpg commuting to work with the AC blasting and rolling hills. Hoping the new 33" tires don't cause the mpg to get any worse. New tires are 57lbs each.

    I just checked my mileage yesterday. 17.0 mpg. 3" Spacer lift on 285 BFGs on stock wheels, also with spacers. But yesterday was the first time I have filled up in probably a couple of months. I'm unemployed so Runner sits most of the time and then only gets driven on surface streets in stop and go traffic. Mileage used to be 17.8 when I had a job to drive to on the freeway.
