amigo wheel/tire ?s

[barney93]

posted this in the newbie section too...

im trying to figure out what offset i need for wheels on my 93 amigo xs.
also, lug pattern. is it 5.5x6?
i have stock wheels with 31x10.5 BFGs right now.
i wanna get new wheels and bigger tires.
i measured the gap from tire to fender-
5.5" in front, and 7" in rear.
thats with the front as high as it can go, and 5 springs in back.

so...
what offset is needed and how BIG can i go?
i would like 33x12.5 on 15s if possible.

[Indyguy]

32x11.50's will fit on the OEM wheels without any modifications whatsoever.

32x11.50's will fit on 15x8 wheels with 3 5/16" backspacing with very very minimal contact with some of the plastic inner fender... even with 2" of suspension and 1.25" of body lift

33x12.50's are going to rub and require some trimming... even with 3" of lift. 33x12.50's on 15x8 wheels with 3 5/16" backspacing and 3" of lift will require trimming about 1" or so from the plastic fascia under the bumper, 1" or so from the back edge of the front fender, and some reshaping of the inner fender liner

none of the above combinations should rub the rear wheel wells at all. I wouldn't go bigger than 33's on the stock IFS for reliability purposes. A handful of people are running 35's... but they have also taken efforts to strengthen the stock axles.

Yes, 6 on 5.5 is the correct pattern

[barney93]

thanks!

so, is the stock offset 3 5/16"?
what if i use a larger offset or some spacers?
would that help?

[Indyguy]

No, the OEM wheels are neutral offset. Pay attention to your terminology there... I said 3 5/16" backspacing, not offset... two different things. My aftermarket wheels (Mickey Thompson Classic II's) are 3 5/16" backspacing, that's the reason for me using it as a point of reference. And no, spacers will not help. The more the tires stick out the greater the chance of them rubbing the sheet metal (but not the frame). You're going to have to trim for 33x12.50's regardless of what you do, so you might as well kick the tires out and gain some stability back.

[barney93]

ok. got it!
those are the wheels i want too.
happen to have any pics.
i wanna see how they sit on the truck-
that is, if your truck is similar to mine.

same reply as in the newbie forum:

my 94 is on 33 TSLs with a spring over in the rear, upper ball joints flipped in the front with the tortion bars cranked up. NO problems at all. ass end sits a little higher but i live with it.

Nothing special on the offset, they are just "normal" 15x8 aluminum rims so the back spacing is like 3 to 4. The only rubbing I get is when taking a hard left and it rubs against the drivers floor because i have been lazy and have not hammered it back. :D

You will have to trim the back corners of the fenders (front) and the bumper.

Nice and shiney there:laughing:

same reply as in the newbie forum:
yeah, sorry about posting in two spots.
i HATE when people do that!
thanks for the responses though.

another question though...
what is "backspacing"?
im confusing that for offset.
can you straighten me out?

[barney93]

btw-
what size are those, and what do you have for lift?

[Indyguy]

32x11.50 on 15x8 wheels, 3 5/16" backspacing. 2" of lift in the rear using DOR Spring Upgradez (http://www.darlington-offroad.com/item.jhtml?UCIDs=534357%7C1322069&PRID=317508), 1.5" in front from cranking the t-bars. 1.25" home-brewed BL. Put the BL on so I could design sliders that didn't hang below the frame rails at any point and so I could lift the gas tank (ended up being able to lift it 1.75"). Helps keep my CV angles less ridiculous as well when compared to a 3" suspension lift.

BTW, in hindsight I should have went with the 33's. Certain variables were present at the time of purchasing the tires that skewed me toward the 32's and I have been kicking myself for it for the past 9 months:shaking:

Pilot: Nominal diameter of center hole that fits over the hub or axle.
Rim Diameter: Nominal Diameter measured from bead seat.
Non-Reversible: Wheel will mount on one side of disk face only.
Chamfer: Breaks the sharp edges of mounting holes to assist in assembly.
Rim Width: Nominal width measured between rim flanges.
Bead Seat: Position where tire rests on rim and seals.
Centerline: 1/2 of rim width.
http://www.bartwheel.com/tech_files/termin3.jpg
Bckspacing, also called rear spacing. Distance from extreme back edge of the rim, not bead seat, to the mounting pad. See Illustration. Lay a straight edge across the back of the rim and measure down to the mounting pad. Nearly all custom wheels use this measurement method to indicate the location of the mounting pad in relation to the rim.

Bolt Circle (Pattern): The diameter of an imaginary circle drawn through the center of each lug hole or stud. Illustration on right.

my Amigo would kick your Amigo's ass







If they were to fight
:flipoff2:
BTW your body pannels are way to perfect, you need to drive closer to some trees :p

No, I need to get closer when taking pictures... there's a whole lotta wrinkley sheet metal on that truck if you actually walk around it and take a look. That picture was taken to make it look nice, not to show how beat up it is:flipoff2: One of many examples:

too bad i made mine AFTER i already smacked it around a bit

[barney93]

with a small body lift;
would i need to extend anything?
like steering or shifter?
probably brake lines?

also, does anyone sell kits?

[Indyguy]

I didn't have to extend anything for my 1.25" BL... just needed longer body mount bolts, had to drill new holes in the radiator to move it back down where it should be, and fabbed up some 1/4" brackets to relocate the front bumper. The only 'kits' for our trucks are 3"; anything other than that and you're piecing it together yourself.

[barney93]

ok...
so offset is the measurement from the center point of the wheel to the mounting pad;
and backspacing is the measurement from the inside wheel lip to the mounting pad?

got a pic of the front hub?
i wanna see how the lock looks with no wheel center cap.

There is a wheel center cap on the front. I just took the caps that came with the front wheels and cut the ends off at the proper length.
