    I am wondering if running an E rated tire compared to a C rated tire is going to make a huge difference on power due to the weight differences ?
    What have you guys noticed ?
    Thanks

    I am running 235/85 r16's KO2's in LR E. They are heavier and stiffer but I have yet to get a flat on hundreds of miles of Baja dirt roads with these tires (unlike by General Grabber AT2's 31x105.x15 LR C that had two side wall failures on back to back trips...). If you are doing a ton of dirt roads it is worth it. If not probably stick with what you are running.

    If only I would have saved it but some website did a test of two 35" tires on the same wheels with the same vehicle. E load tire at almost 80lbs and c load at around 48lbs.

    Acceleration was a .2 second difference. Mpg was a .3 difference. Only thing worth noting was stopping, dont remember exactly but it was over 50ft extra.

    I searched for years on the lightest tires, I used to be able to tell what every 33" tire weighed. When I saw that post, gave up and now run e load 33s at around 65lbs a piece

    Wow, if that's what's happening with the Brakes, imagine the rest of the suspension....:ballchain:

    I ran e for years no problem.

    Went back to c and realized the e rode like bricks. Cs soak up a lot more of the road.

    The benefit to move to an E is if you are constantly in harsh terrain where damage is a high risk.

    Currently I'm running 35×12.50r17 Toyo OC AT2 xtreme E load. The lungs are further apart with the xtreme version. Unsprung weight you will feel but rolling resistance is something a lot of people overlook. It's an aggressive AT tire but it's not a crazy rolling resistance either. If I had the same weight and size tire but crazy aggressive tread pattern, I would feel it even more. With all that being said, if you're running the same size tire but changing it to e load I wouldn't think it would make that big of a difference. If you add a crazy aggressive tire and e load then you'll feel it a little more. It will affect a 4 banger more than a v6. I'm not trying to make it more complicated but there are a lot of elements that go into it. Your tolerance level has a lot to do with it too. I've know people to run 35s with stock gears and say it's not that bad. Then you have someone standing right next to him complaining about power loss moving up to 285s with stock gears. Just going off of everyone's advice the guy with 20 lbs more per tire running 35s should be the one complaining but that wasn't that situation. An easy way to look at it is many people have done way more than what you're talking about and still consider it very tolerable but each element you change(unsprung weight, tire height, rolling resistance) will affect power to some degree. You just add one element and it won't be too different from what you're used to but when you start combining multiple elements together and the effects will be more. Hope the info helps.

    Really it's best for towing. Never lost a tire on a trail in 15 years down airing to 12psi.

    Knock on wood.

    Yes, that too. Since I never tow heavy anymore I do forget that.

    115 load Cooper ATW's. Good in the snow and as good as can be expected ice traction. Does well on the beach/sand. I do fire trails, light towing nothing requiring an E rated tire. Quiet on the highway.

    Currently on E load All Terrains (KO's).

    Are they heavier? Sure. But so are bigger tires in general.

    Do they suck all the power out of your truck? No.

    Have I ever gotten a flat? No.

    Street? Go C load.

    Off road? Get E load.

    D range would probably be a decent compromise, there is definitely a much more limited selection of sizes and tread designs.

    E rated BFG KO2s....been wheeling almost every weekend for nearly 2 years on them (2nd set now). Never once had a puncture, blowout, flat or tire issue of any kind. I'll never go with anything but an E rated tire for a wheeling rig.

    That said, they can be brutal on the street. You feel every bump in the road and they are heavy (bad MPGs). So there's a definite trade-off for the offroad peace of mind.

    I've never owned anything different than the E rated that are on my Tacoma now (I bought it with them - on my 2nd set). So I've never known anything different.

    I've always attributed the "better" street ride from my '17 4Runner to the fact that it's almost 15 years newer, quieter, and has lame softy street shocks (it's the DD, and wife wants the soft ride for road trips etc...). The little street slicks it came with I'm sure contributes to that ride, though...

    Yeah for a while I wondered why my ride was still so rough even with the new suspension (Kings/Icons) and I realized it's the tires. Airing down helps a ton offroad but they are still way stiffer than a more street friendly tire. Especially on a relatively light truck. Just one of those trade offs.

    I do think KO2s are a bit more notorious for it than most because of their stiff yet nearly indestructible sidewalls...other E rated tires might not be as rough on the street.

    I run Toyo AT2 extemes on my F150 , they are E rated and I run them at 34 psi on the street so they arent hard as rock . They also wear evenly at this psi.
    I was just concerned about running an E on my lil taco being that its even lighter than my other truck.

    With my Toyo Open Country tires that I previously mentioned I used the chalk line test to get the tire press correct

    Found that 28psi I got even tread wear even with a load range E tire

    I ran C-rated tires for years and seemed to always have a puncture or 2 in every set I ran. Since swapping to E rated BFG “KM2’s, KO’s and now KO2’s” I haven’t had a puncture in the last 8 years. Sure the E’s ride rough, but it’s a truck and I hate flats.

    Edit: I also run mine at 32psi

    This is a good thing to point out: that just because the E rated tires have a max of 80psi, you don't need to run them that high (that's just if you're towing really heavy loads (like out Tacos could handle that much weight anyway, lol). There's no need to Flintstone it and run "hard as rock" pressures.

    I've been running ~32 psi on the street the last decade+ with KOs, and they wear very evenly at this pressure.

    my god I couldn't even imagine what running KO2s at 80 psi would feel like...one tiny rock in the road would probably make you lose control of your truck
