    Hi Everyone ,

    I'm planning on getting tires for my TRD wheels but can't decide between: KO2 265/70/17 vs 275/70/17.


    Beside the 10 ply and 10lb more for E. Is there really any benefit for going with 275? Will it be noisier and lower MPG as well? Thanks guys for your input.


    275/70/17 Load Range E 3195 lbs. only avail.

    Tire Weight 55lbs

    Sect. Width 11"

    Tread Width 9,2"

    Overall Diam 32,2"

    $223


    265/70/17 Load Range C 2470 lbs

    Tire Weight C 45lbs

    Sect. Width 10,7"

    Tread Width 9"

    Overall Diam 31,8"

    $222

    The 265 is 6 ply, which is still good for everyday driving.

    I thought when I researched tires two months ago the KOs were not available in 265 load range "C" but I could be mistaken.

    MPG's will definitely decrease due to increased rotational mass, wider cross section (wind resistance and rolling resistance), and increased overall diameter. How much is the real question?
    Noise should be about the same, as they should have identical tread patterns. However the the increased contact patch might make a small increase in noise, nothing you'd notice though. The increased ride stiffness of the E rated tire would be a more noticeable difference between the two tires than noise.

    I believe you but post a link to a "C" on a retailers website. I am curious because I thought I looked thoroughly.

    the 265s are available in load range C. I'm debating getting this exact setup this week. From all my research (lots of threads on T4r.org) is that most experience about 0.5-1.0mpg loss. Most say they don't notice the extra weight on the 265s C load. Stepping up to 275 they notice the extra weight and the ride is much stiffer. Seems there have been a fair amount of people that have downgraded to the 265 for one reason or the other, but mainly due to the stiff ride of the E range tire.

    The tires look fantastic.

    I went 265 / 70 / r17 with a 2" lift and while I could accommodate a larger tire, these look appropriate, and I've noticed maybe a 1 MPG loss overall. ( I went from a P-rated to a Load Range E, so that's where the MPG loss came from).

    A friend went with 275 / 70 / r17, they look very similar, and we suspect his rubbing (he has the same lift) is from the negative offset from the aftermarket rims which are -12mm. I'm using stock trail rims, +15mm offset.

    All in all, I don't think you'll notice much of a different either way, but if you keep the trail wheels, both shouldn't rub. Start going negative offset with aftermarket rims, both are likely to rub.

    For what it's worth, my Load Range E tires on a 2" lift rides better overall than stock, if a little more firm in a good way due to lack of body roll in corners, and at highway speeds. I was worried about the quality of ride, but even my wife said she didn't notice it being different.

    Thanks! Right now I'm leaning toward 265/70 17. I do most of my driving in the city/freeway and and trail about two weekends a month.

    Hmmmm, I thought I searched thoroughly, I guess I did not. I am happy with the tires I ended up buying but maybe when it's time for a new set, I will give these a spin.

    With respect to 265 vs. 275, me personally, I can't see buying a $40K vehicle and having a rubbing issue or having to modify my fender wells. I am not an off-roader, though, if I were then it would make sense. Why did I buy a 4Runner if I am not an off-roader, because it's a quality vehicle that looks good.

    I'm an avid off roader but wanted to keep thing smooth for the road trips to get to the offroad locations. I can tell you it's nice not having to cut up the fenders. I want it to be good off road, but I'd like to maintain as reliable as a ride as I can. That's not a knock on anyone who goes big, more power to them, it looks great...I just wanted a KISS vehicle for exploring things, so my build revolves around minimal lift, lighter weight armor (delete fill plates on sliders...1/8" steel skids, hybrid bumper with synthetic line winch).

    I agree with you, however, it's a matter of taste, and this vehicle is an extremely capable vehicle that I still want to have looking good on the road for the majority of our camp trips and such.

    DescriptionBFGOODRICHALL-TERRAIN T/A KO2Lea en español
    The All-Terrain T/A KO2 ("KO2" for Key benefit On- and Off-road with 2 identifying it as BFGoodrich's 2nd generation KO tire) is an On-/Off-Road All-Terrain light truck tire developed to meet the needs of jeep, pickup truck and sport utility vehicle drivers who want confidence and control on- and off- road. The All-Terrain T/A KO2 was designed to deliver go-anywhere traction along with outstanding durability, great wear and year-round traction, even in snow.All-Terrain T/A KO2 tires feature a racing derived cut-, chip- and tear-resistant tread compound that delivers longer life (up to 2 times the previous generation tire's treadwear on gravel roads). The compound is molded into an aggressive, computer optimized, high-void all-terrain pattern with interlocking tread blocks, innovative siping and multiple loose object ejection features to combine off-road durability and traction with on-road handling and acceptable noise.Upper shoulder Sidewall Armor features a tougher sidewall rubber compound that's twice as thick as its predecessor and a Serrated Shoulder Design that delivers additional traction by providing the clawing action necessary to develop traction and steering control in deep dirt, sand or on rock during "aired down" off-road driving.The tire's internal structure includes twin steel belts reinforced with spirally wrapped nylon on top of BFGoodrich's TriGard, 3-ply polyester cord sidewall ply construction (2 plies for Load Range C tires) for strength and durability.Single strand beads (a single strand of bead wire is continuously wrapped multiple times until the desired strength is provided) enhance the tire's fit to the wheel to improve uniformity and ride quality.NOTE: BFGoodrich All-Terrain T/A KO2 tires meet the industry's severe snow service requirements and are branded with the mountain/snowflake symbol.
