Re: For those that dont understand backspacing and offset

I am looking at a set of 18x8 inch , 5x120mm 35mm BMW wheels for an S-10. The S-10 is a 03' 2WD. I am pretty sure I would need a 1-1.25" spacer. Is that correct?

Also, BMW wheels are hubcentric, instead of lug centric. How would this effect the wheel on the hub of the truck?

As for tires, I am not sure what I would need. Any suggestions? The truck will also be dropped 2/3.

Thanks,
Trey

Re: For those that dont understand backspacing and offset

Sorry to bother you, I have a quick one.

I have a 98 Sonoma, dropped 3" with coils in front and 3" with leafs in back. A member on another forum has 20x9 irocs all the ay around with 255/35-20's. he hasnt responded to my posts yet and I found some on ebay that have a +15mm offset with 5.59" backspace, 20x9. I already bought the 255/35-20 toyos and need to now for sure if these wil fit before I buy them, let me know what you think. BTW right now I have the ZQ8 wheels with 265/50-16 that do rub pretty good on sharp turns. The truck is not a zq8 and is lowered 3" from stock height.

Re: For those that dont understand backspacing and offset

I want to buy a set of wheels but they are for a 4x4. i cant find em for a 2wd. they are 20x8.5 and have a +35 offset. it doesnt give the backspacing. how large of a spacer will i need so i can roll on them and still tuck when i lay out?

Re: For those that dont understand backspacing and offset

wow... havent checked this thread in a while... damn theres alot of questions. Ok here we go...

-Thanks.
For a 9.5" wide rim you should run 5 1/4" backspacing. The wheel should tuck nicely up in the wheel well with that 275 35 20 tire. One thing is those.. as long as you know your gona have to cut out the inner wheel well and inner bed sides or else the truck wont layout.

Size: 18''x7''
Bolt Circle: 5x100mm
Offset: +45mm

Would it work?
Nope not a chance, the bolt pattern is way off and the offset is way off. The only way these would bolt up is with a 1.5" thick adapter that changes the bolt pattern from a 4.75" x 5 down to the wheels 100 x 5 pattern.

I dont have fourth gen wheels on my truck. I'm running 20" boss 301's. But no a camaro wheel would not work with only a 1/2" spacer... ya need a 2" spacer for a 2wd truck.

also if it matters it says +35.00 mm offset

please help/

theres also an identical rim with 3.75 back spacing and -6mm offset.. but thats not enough back space.. correct!
all depends on what your doing with the truck. First off for the first set of wheels.. with the 5.375" of backspacing will not work , thats way to much. Now the second set of wheels with the 3.75" backspacing would work just fine if your only lowering the truck. If you are baggin in the future, those tires could be extremely close to the fender lip and may possibley not tuck to well.

nope the backspacing is way to much for a 2wd truck. You would need to run a spacer.

not sure where, but just look around. As for what ya need... your gona want a 20 x 8.5" wheel with right around a 50mm offset. Also the bolt pattern is 4.75 x 5 if you didnt know that allready.

yeah you could get away with 5" up front.. but like ya said, there is gona be some rubbing possible during sharper turning.

yes correct you would need a 1.25" - 1.5" spacer that also adapted the bolt pattern over.

they would work, but theres a good chance the wheels will rub the control arm or the frame when turning. You could allways pick up a set of longer wheel studs, and 1/2" thick spacer to push the wheels out a little further to clear things better.

You will need a 1.5" thick spacer. Is the bolt pattern on the wheels the correct 4.75 x 5 pattern for our trucks or is it something else.... cause its no problem to change the bolt pattern with the adaptors.

4" with a 7" rim
4.5" with a 8" rim
4.75" with a 8.5" rim



feel free to add extra rim sizes and widths if you want.

EDIT! I was looking at my original post, and now realized why it is confusing some people, the offset desired will change for the width of the rim. I posted a 0-4mm offest... I should of posted this

7" --- 0 - 4mm
8" --- 4 - 10mm
8.5" --- 5 - 15mm

now these are just approximations, the wheels you chose can vary from these measurements a little and still work.
what about for a 4x4, what backspacing does it take for each wheel. like 7" etc
I have an 1988 s10 4x4 blazer and am tryin to find new wheels for it but dont know what backspacing to look for

responed to your pm, yeah you should be ok, but if not maybe a 1/4" spacer would help things clear better.

Re: For those that dont understand backspacing and offset

Dumb question-sorry. I have a 2001 2wd reg bed with a 2" lift and 31 and 10.50 s on the old, funky white spoke rims (painted black). Surprise! these tires rub at the frame and the fender wells. I am not sure if the white spokers are all the same, but any estimates on how much of a spacer I would need to clear the frame-I'll trim the fender wells as needed. Thanks for your time and reply.

Re: For those that dont understand backspacing and offset

I just bought 31-10.5-15 Bf Goodrich All terrain for my 95 4x4 4 door blazer. Im looking to get some Iroc rims but I havent been able to find someone running these on the search. I am looking for something that sticks out a few inches. any help would be appreciated, I plan on tweaking my torsion bars and perhaps a body lift to clear the tires.

yes s10 blazers are the same as an s10 pickup.. they all run the 5 x 4.75" bolt pattern. You will need a adaptor that is 1.25" and as you said adapts the bolt pattern down for the wheels.
