    generally 235/75/15 are 28-29" roughly... so for more you could go to 30/10.5/15 or 31/10.5/15 and you may even be able to turn 33/10.5/15 depending on your gear ratio but i would say with 33's would be a PITA to turn and kill you MPG even more than they are now....

    go with 31x10.50x15.

    wont need different wheels, and will still fit with no issues. as the level II FX4's came with that size from factory.

    thats the biggest you can go before needing new wheels, or a body lift/suspension lift.

    tjhe tires you have now are 29" tires. so you will gain about 1/2" to 3/4"" of lift from the tires alone.

    its in inches.

    31" tall
    10.5" wide

    mounted, they will be a little smaller though. all tires ive ever seen when mounted and on the vehicle, are always smaller than advertised. I think my 31's when I had them were right around 30.5" tall.

    my 32's are sitting at 31.5" tall as well.

    where you from? canada?

    im american. cali. so 75% of 235 is about 176. 176 is 10.5inch?

    no, your current tires are 28.9" tall.

    235 is 9.25" wide.

    so, your tires are 29x9.25x15

    ones you should get, are 31x10.50x15

    okay cool. but how did you get 9.25 from 235/75
     
  14. 06FordFX4

    235 is the width of the tire.

    235 mm is equal to 9.25 inches.

    75 is the percent of the width, that is sidewall. so, 75% of 235 is 176 which is equal to 6.9"

    so the widewall is 6.9" * 2 since its round = 13.8 + the 15" rim = 28.8

    thats the long way of figuring it out.

    but, just go to google, there are tire size converters that will convert them for you.

    and i can go to 10.5 inch width without worrying about it being to large?
     
  16. 06FordFX4

    06FordFX4 Canadian Redneck

    yep. stock wheels are 7" wide. so you will be fine with a 10.5" wide tire.

    like i said earlier, some stock rangers come with that sized tire. so its all good.

    how bad will my mpg or towing or gear ratio be affected?

    what gears do you currently have in the truck?

    open your driver side door, and look at the sticker. there will be a section that says axle code.

    post what it lists under that. Will help determine how the truck will react to larger tires
