Luch Posted June 7, 2006 Report Share Posted June 7, 2006 I have estimated the weight of one of my tyres (175/60R14) to be close to 7-8 Kg. How much weight is required to balance it? Why if the weight is too much a vibration on the steering wheel is still felt even if the balancer shows that the assembly is perfectly balanced? I am assuming that the car is fine.

discount tyres dan Posted June 7, 2006 Report Share Posted June 7, 2006 are all the wheels perfectly round? are they after market rims? if they are do they have the correct spigot rings fitted (to make the rim fit snug on the hub). is the vibration at high or low speeds?

I am assuming that the car is fine. 7-8 Kg is very low in mass to require excessive corrective compensation... There are three main areas that may realise a reason 1:- Operator error = poor workmanship 2:- Calibration error= poor maintenance 3:- Manufacturer error: = wheel centre not centred or designed for the balance's dye Quote Link to comment Share on other sites More sharing options...
Luch Posted June 7, 2006 Author Report Share Posted June 7, 2006 I think the rims, original Daihatsu alloys, are alright as didn't have vibration with the old tyres (Bridgestone Potenza). I have fitted now Nankang EX601, however they have been balanced with a lot of weight. Front near side 60gr, front off side 75gr, while the rears have 20gr and 40gr. Still had a bit of vibration which was cured as soon as front and rear wheels were swapped. Take into account that this is a light car (about 950Kg) and seems sensitive to vibration. The balancing was done on a Hunter GSP9700 as normal balancers have failed. Quote Link to comment Share on other sites More sharing options...

Tyre manufacturing does vary in results according to the make of tyre.. The cheaper tyre tends to require more compensation... The reason i intend to explain in full as a wim knowledge topic very soon. Quote Link to comment Share on other sites More sharing options...
