    toyota fanatics...

    current setup :
    2wd on drop spindles with maybe 1-1.5 torsion down
    3in block in the rear with mono leak stock spring

    bought 15x10 wheels with 4.5" backspacing
    i believe offset is -25

    4wd fenders up front also

    wondering what tire size would fit flush with no spacer or with spacer if need be and not stretching the tire?

    i don't want to rub at full lock or anything of that sort either. but i want the fat tire in the rear and maybe slightly smaller in the front or square all around

    thanks!

    current pic of truck also

    Im setting up similar specs on mine. I'm looking to go between 245/255x40 the only difference in our setups is offset. I should be good at 0. But -25 might be enough to make you go down to 235..

    Have you visited willytheyfit.com

    Erwin,

    thank you! I’m going to check out that site now. I was running some ESR on 18x10.5 and that was stretching a 235 so I’m hoping the 15x10 won’t stretch on that 235/40

    Play with the offset feature and compare how much the wheel moves inward to your current set up.

    235 will stretch on a 10. I had 245s on a 9" wide wheel and that was squared so go with that for reference.

    take a wheel off, load the suspension and measure from the whee mounting surface on the hub to the edge of the fender. That should help get you a ballpark idea of how much barre you can manage to fit up front
