Dear All,

As mentioned above, i want to know the whether too much negative offset in OEM wheels can cause tire vibrations. Current car is an E46 318ci with stock undercarriage. Wheel hub is still using stock and standard which sits quite inside the fender. Current wheels are OEM 17" with ET37 offset. My mechanic already gave me a preamp that i will experience slight vibration and on-wheel balancing can only reduce it but not cure it completely. As he said, i did feel slight vibrations randomly at any speed depending on road conditions.

Should i change back to wheels within my 318ci spec or there's something wrong with my car ? For guys who didn't know my car, its running on 1JZGTE engine with custom driveshaft using Toyota Crown's and E46 flange to rear axle with 3.46 differential.
Yes but when we tried with regular hub centric ring, the wheels couldn't fit. The difference between the wheel bore is only by 2 mm so we have to manually shave off the extra metal to fit the wheels in completely.

there goes your answer...

there is bullshit reason wrong wheel offset = vibrate... nope.. dont ever believe that...


the reason wheel vibrate:
-damaged wheel (bent/wobble)
-damaged tyre (wire inside broken/out of balance)
-damaged wheel bearing
-wrong hubcentric fitment <--- your real reason by manually shaving that wheel/hub area to fit...making it even worse....dont pour money somewhere else... settle this properly, then the vibration issue will be gone for good

Something like this, my stock 318ci lug nut is M12, while the wheels itself is M14, i have to custom a lug nut spacer just to make sure the lug nut fit in the holes completely. Those spacers actually eliminated 90% of the vibration issue but my mechanic pre-amped me the tyres are too far out, almost stick out of the fender, so i will definitely feel some vibrations.

u really need hubcentric

either like this to convert from bolt in M12 screw into M14 stud to fix the wheel





or use 1 big center cone to keep the wheel center in the hub along with those "m12 to m14 lugnut bushing"

My issue is there's no hub centric ring suitable for either the car or rim. The vibrations happened on 160-180 km/h (electronic limited)

I am currently loaning a properly spec rim to fit on the E46 and test it again. High chances are the vibrations will go away. Hope for the best.

This is also my consideration, however, my wheels are already very far out and align with fender, if further away from the car body and i will need wide body kit

I think you can get the center cone for your rim.

or last resort... look for some proper fitting rims
I am doing this now, traded rims and tyre for another set of 18' rims and tyres. I am lucky enough to get it loan first before purchasing. Will be fitting it this month, wish me luck.

Yup, should be able to. Mine made of aluminum. If no size, the tyre shop can measure and get machine shop to machine a set for him. Earlier days I did that, nowadays most are ready made....

Even 1.5 mm diameter hub centric ring can be made ?

Dear All,

Just came back from fitting a new set of rims with busted old tyres of mine that i am still keep it for emergency use, thank god i am still keeping it so i can immediately put it to use. I speed up to 190 km/h just now, looks like the rear seat vibration is rectified and now mostly is the steering wheel vibration due to this old tyres can't be well balanced anymore. The centre bore is very tight fitting without the need of centre hub ring. I will fit in new 18' tyres this weekend and have another round of proper test driving. Hopefully this will solve the issue once and for all. {Picture below for the rim i am using. It's from a BMW X3.

Or can approach any company which supply machine part for factory. Most of the time they do custom parts/jig for machine using stainless steel.
I know one from Johor (if not mistaken). The lady said they have done has some custom job in bulk order and one off job for people wanting custom part (most of the time will be bracket) for their ride.

If fitting then no need the centric ring ......lol
I can't believe just 1.5 mm difference in centre bore can give me so much trouble. Is it especially sensitive to BMWs ?

actually on any car... hence u see many car with aftermarket wheel using the hub center cone....


and universal type spacer...also have risk of vibrate when using thicker than the lips on hub center bore...

The previous wheels are manufactured on OEM spec, guess the finishing work isn't very good. With the 100% original rim, the fitment is perfect, strangely enough, i think the steering responsiveness just got sharper with larger wheels, although my current tyres are shit right now.

imagine your rim, 1.5mm off, that translate to lots of vibrations... thats like a 3mm total vertical dif per rotation

Without the centric ring there is free play, so the whole wheel is off center. Spinning at high speed equals vibration....

How about smaller lug nut on a hub centric rim ? Lets say if the hole is M14 but lug nut is M12?

Yup, I saw your post on them. Conti uses screw to mount unlike most others uses lug nuts.....
In that case i think the bolt spacer should be sufficient to fill in the gap ? Or should i go with a stud conversion kit ?
