balancer weights ideally removed and then run it on the machine.

however i can tell you 90% of the shops the balancers have never been calibrated over the years. Another issue is the weights, some of these cheapo weights will have you chassing weights, keep adding and keep removing and back and forth. My personal rule, if i need to add more then 30g, i end up getting the shop to rotate the tire on the rim. and try again.

one of the wheel balancers that i love are hunter's, normally only found in premium shops. These machines are spot on. Those shops cost more to do the balancing but ive never had an issue, and with the smart weight option, they will rotate the tire on the wheel to minimize the amount of weights used.

Hi Calvin,

I've been patronising Kim Heng  SS14/1 for a decade or two for their quality workmanship and friendliness.
About a month ago they did an internal patching (not plug type) on my Avanza rear left nail-punctured tyre.
During tyre balancing, and to my'surprise' they took the trouble to zero out completely the unbalanced "outside 5 grams inside 5 grams combo" out-of-balance tyre on a non-steering rear wheel - a scenario some or most tyre shops would call it quit and consider job done.

Another tyre shop recommended by someone in this thread is Weng Tat along the same road, which I find it's space is tight and crowded.

Tyreplus- SL Car Care Klang is another tyre shop I would recommend.

Hope it helps.

Note: I visited Kee Hin some two years ago for a wheel alignment correction job on my Avanza, not for accelerated tyre wear problem which my Avanza didn't have,  but for normal and 'simple' problems of car drifting/pulling to left hand side and steering wheel crooked/off centre to one side.
Instead of resolving them, the two problems had gotten worse immediately *after* the job.
Hence, beware of it's wheel alignment competency!
