wheel sizing

[bears4x4]

Backspace 4.53 in. ????????? what does this mean
Max Load = 3200lbs
Hubcentric = No ????????? what does this mean
Offset = -12 mm ????????? what does this mean

Will this work on a 2000 f350 with a 6" lift

No because Super Duties use Hub centric, meaning that the wheel is centered on the hub and not the lug nuts. Those are lug centric. The back spacing is for clearance for the brakes. I am not sure what you need. And the offset is 12 mm to the center of the truck. Center of wheel vs center of hub where is blots up to. Clear??? (no).

Here you go, these descriptions from tirerack.com are great and include a diagram that should clear it right up.

Offset and Backspacing:
Wheel Tech - Offset

Centerbore:
Wheel Tech - Centerbore

Wheel / tire size calculator / comparer - WHEELSMASTER


i use that little program.. pretty awsome... lets you compare.. and what not.. used it alot

backspacing is how far the lug mounts in comparison to the inside face of the wheel. The offset is another way of measuring but it measures from the center of the wheel.

Ok im confused this is a copy from tirerack.com,
"Some wheels are non-hubcentric by design. These are known as lug-centric wheels. With these wheels it is critical to torque the lug hardware with the vehicle on jack stands, off the ground. This allows the nuts or bolts to center the wheel and torque down without the weight of the vehicle pushing them off center."

what im wanting to do is 6" lift with 18"x9" wheels with 35" tires heres the wheel spec.
18x9,
8 on170 Bolt Pattern
Backspace 4.53 in.
Max Load = 3200lbs
Finish = Bronze
Hubcentric = No
Offset = -12 mm
includes Hubcentric Ring included where applicable
does this mean these wheels can work for me??

 

[DaveBen]

If your wheels are lug-centric they are NOT hub-centric. Your specs look like they will work. The hub-centric ring allows them to be used both ways.

the wheels are through 4wheelparts , i just called they say they will work i just like asking here to make sure. i guess keep a warrenty just in case???

 

[big_rooster]

from what i've found the only vehicle that uses the 8 on 170mm lug pattern are super duties so all wheels you find with that pattern will fit just depends on what backspacing you choose.

what off set would be better i will have 6" lift on my truck
35 x 12.50 x 18's
Backspace 5.71 in. w Offset = 18 mm
or
Backspace 4.53 in. w Offset = -12 mm im thinking this right????
