wheel off set help

[JDM-MAT]

Right I am not very good with off sets so could some one help and explain them to me. Also I have a set of alloys at home how do I find the off set on them.

Thanks, mathew

The offset of a vehicle's wheel is the distance between the centerline of the wheel and the plane of the hub-mounting surface of the wheel. It can thus be either positive or negative, and is typically measured in millimeters.







Positive
The hub mounting surface is toward the front or wheel side of
the wheel. Positive offset wheels are generally found on front
wheel drive cars and newer rear drive cars.


Zero Offset
The hub mounting surface is even with the centerline of the
wheel.



Negative
The hub mounting surface is toward the back or brake side of
the wheels centerline.

Is this stamped on the wheel somewhere

yeah have a look, most wheels it's cast into the metal though some have labels.

I found something saying 17x JJ off set.

[rosco83]

that's the rim size & width, you should hopefully see more information, i.e "ET38"

[JDM-MAT]

Its very dirty so will have to clean them up, the back tyre size are 255/45 zr17 and fronts 236/45 zr17. I think they will be huge on a mk2 mr2

[rosco83]

Not all wheels have offset info but most do. Give one a good scrub up and see

[JDM-MAT]

Think they will be to big

[rosco83]

Mine are 17x8 ET35 with 215/40 up front, and 17x9 ET38 with 245/35.

Roll the rear and you can get some big tyres on, 255 is common on the rear but fronts would need changed regardless of offset i would think. See if you can see the fitments and i'm sure some wheel guru's will help with fitment. They helped me anyway!

[JDM-MAT]

I think the wheels will fit with different tyres 40 in sted of 45

[SFLee]

40 235 will fit (may be coilover only though)

45 will not in the front

offset will be a bit out about 5mm if it is from supra, (supra use 45 profiles)

yeah to big for fronts
