    Hey all i drive a 2017 Tacoma TRD Sport. I want to do new tires on my factory wheels I'm looking at the BF Goodrich All Terrain T/A KO2 (https://www.bfgoodrichtires.com/tire/bf-goodrich/all-terrain-t-a-ko2)

    I was wondering what tire i have to go with. I know i can go 265 70 R17 but at the end it has the numbers 112S or 121S I just wanted to know what that meant? Which one will fit on my truck? Thanks in advance! 29598380_1709878025714582_30051382842894_02e4d0918df1855460a2f8426c0a6ab4bdcbec0b.jpg

    The 112 and 121 are the respective load ratings of the tires. 112 is a C load range tire and 121 is E load range. This can also be interpreted as how many plies the tire has. More plies equals a stronger, more durable tire that can handle more weight (towing), but it also amounts to a much heavier tire that rides considerably rougher. Especially on lightweight trucks like ours. The D and E range tires are really meant for the bigger trucks. I personally have C load range tires (112) and would recommend them if you are at all concerned with ride comfort and unsprung weight.

    Check build thread
    Get the 112 .

    E rated 121 load is major overkill for our trucks.

    Why won’t they make a C load 275.... the C load 285 is a lot lighter than the 275...

    Yes go C load range 265, less power loss and better mileage than the E rated tire. Unless you either tow a lot or Offroad enough to need the heavier tire. 112/109S C RWL

    The C Range should be a tad cheaper as well to the other benefits listed above.

    Tons of threads on here about that..from economic to high end.
    Depending on how you use your vehicle depends on the lift.i recommend searching threads for your answer! You can go ready lift(cheapest,not offroad) to Billstein 5100’s and Frankenstein it, to completes such as OME,Icon,King..then you have progressive and regressive shocks..

    You can get a 255/75/17 BFG KO2 in C load, tall as the 275/70/17 but not as wide so it's lighter and no issues rubbing when wheel offset is a factor.

    I'm lifts eventually causes more stress, future problems. I have owned a 4wd for the last 30 plus years and had a few lifted trucks. Your always chasing an issue, allways re balancing tires and worn suspension. Few get by with little issues and some don't. Me personally I'm done with lifted vehicles and chasing wheel weights. I been in a few where no issues at all, just wait.
