Fuchs wheel weight placement Options

[bbrock]

After 37 years of 914 ownership, I'm finally about to buy my first all new set of rubber for my 4-spoke Fuchs. I've removed adhesive weights both inside and outside the rims.

Question: Can wheels be properly balanced with weights on the inside only?

Adhesive weights on the outside don't really bother me that much but if they can all be installed inside without sacrificing balance, I might as well request it.

I got curious after noticing the shop that mounted rubber on some junkyard-purchased alloys for my beater SUV placed them all inside without asking. Going to a different shop for the Porsche so count on them just doing it unless I ask.

Depends on the wheel width. Static balancing, only the overall wheel is considered.

Dynamic balancing takes both wheel OD and width into consideration.

You may not like it, but dynamic balancing weights might be be called out on the outer part of the wheel. Moving them inboard is close enough but a compromise.

As the object grows in length, dynamic balancing weights are placed appropriately, wherever needed. Think of a crankshaft. Balancing weights are not on one end (i.e. crank pulley). Your car may not be rotating the wheels at crank speed (e.g. 6000 rpm), but at +100 mph, proper balancing makes a difference.
