    I would think they would.....if anything a lil rolling of a 4wd fender. My +40s have some space.

    +35 would be fine. 8.5" on +35 isn't toooo bad really... I'll be worried if it hits the arms on the inside or anything.

    All I can say is I have 20x8.5s +40 and they have some clearance. I have not rolled my fenders at all and I still have plenty of space. I can measure it tomorrow if you want. My truck is put away for winter or I would do it right now. I have zero rubbing on the inside, even turned fully in each direction.

    Offset is the relative position of the hub inside the wheel.



    [ Outside lip
    : Hub
    ] Inside lip


    Positive offsets
    [: ]

    0 Offset
    [ : ]

    Negative offsets
    [ :]


    The hub on a truck is a static position unless you can change up stuff.

    FWD cars generally use high positive offset because the wider front axles. RWD cars generally have a lower positive offset, or most people go extreme and go negative offsets.


    comparision.

    Toyota Pickup.
    Factory steelies are +38 offset on a 14x6" wheel.
    It has gap from the fender to the tire, horizontally.
    Say we had a similar 14x6" wheel, with a +20 offset.
    It will sit 18mm closer to the fender than the factory steelie did.

    yup, you're welcome!
    high positive wheels means that you may rub something on the inside of the wheel
    low positive wheels to negatives means that it may rub the fender

    a high positive number for our trucks may be considered the high30-50's on a 8" and wider wheel. that's when things get really close and iffy. but then you can also play around with spacers to "lower" the numerical offset of the wheel itself.


    I think you understand.

    example...

    +40mm offset 18x8.5" wheel.
    Add a 20mm bolt on adaptor spacer (mounts onto vehicle's hub) (this is also a big adaptor lol)
    End result is a...
    +20mm offset 18x8.5" wheel.








    Does anyone know how wide our wheel wells are?

    This is probably the best description I've seen yet of how offset works, in relation to the Toyota trucks.

    Thank You!

    So, with say, something like a Cragar Soft 8 -15"...

    The zero offset brings the wheel 1.5" closer to the fender lip, the extra 1" in wheel width... does that whole inch come closer to the fender lip?

    Speaking strictly stock suspension on the '89-95 2WD... what would be happening with the front wheels when the wheels are turned?

    OK, I'm confused again... I gleaned that the Cragars are zero offset from Toyota Nation, but they're talking about 17" rims, on the 4x4's.

    Looking at the Jegs site for these rims, they mention rear spacing of anywhere from 4 to 5, depending on the rim width...:shrug:

    My goal is to take my '89 2WD - and put a set of these rims on it, and I'm looking to have the edge of the tire stick out just past the fender lip (keeping the suspension height stock, or maybe even raising it slightly if I have to). Will I need 15's or 16's? Or 15's with spacers?
    There's so much to learn here :rolleyes2:

    15's or 16's just determine the overall diameter, which you are totally aware of. I doubt it'll affect anything. Tire size will matter a bit, depending how tall your want your sidewall and overall tire height to be.

    How wide is the Cragar Soft 8 you are looking at?

    Well I guess I have to determine how extravagant I want to get with tires. All seasons with some beefy tread, but not too expensive - I'm going to be on a bit of a budget.

    I'll probably go with 15" rims because they're quite cheap, so I guess it's figuring out the back spacing with the various widths

    15x7 : 4" rear spacing
    15x8 : 4" or 4 3/4 rear spacing
    15x10: 4" rear spacing

    Cragar 397-Series Black Soft 8 Wheel - JEGS

    As I mentioned before, I don't mind adding some lift.

    Sorry, NAM, I reviewed that last post of mine and apologize for not being more specific.

    So to bring the tire out JUST past the wheel lips (and I'm going to go with 4x4 front fenders), what would be my ideal tire width, taking the rear spacing into account?
