Road force balancing done with great results!

My Z coupe was always unsettled at motorway speeds even though I have replaced 90% of my suspension and done the alignment and wheel balancing many times.

Was going to change my nearly new tyres as a desperate last resort thinking they were the problem.
But I took a gamble on having road force balancing and my cars never driven better. The ride is smother and now perfectly steady at any speed I wish I had done this ages ago.

One of my front tyres and one rear had a hard spot creating 60lbs of pressure. Had the tyres moved to a better position on the rim so they were within tolerance. Finally enjoying my car again!

When I worked at Goodyear the car tyres went through a quality control test for radial and axial runout. If they were within the manufacturers specified oe telerence they went for oe. If they were out of that tolerence but within the next then they went to retail (kwikFit etc). Outside of this they were scrap. So basically the best tyres on your car will be the ones it came out of the factory on!!

What about the tyre company's who don't supply oe to manufactures. Guess there tolerances as poor.

I didn't work on the car tyre side at Goodyear but had a tour around that dept with one of the staff. Amazed that all the manufacturers had different OE tolerances. What was also mind blowing was the fact that at its height wolverhampton was producing some 24,000 tyres a day

I worked in the chemical compound and test areas for about six years around all the western world tyre manufactures and it's true that OE tyres are the best, but there bad ones are not bad.

The worst are bead faults and they are constructed through wound wires, and the very best pattern eg six wrapped around a seventh would be found on Pirrelli tyres, the Vredestien tyres had the worst bead wrapping.

Goodyear tyres were the median type. Avon were precision and continental were above average.

Yokos were just emerging as a premium race tyre and possibly the most accurately built tyre.

Just my opinion from about 10 years ago.

Bit of a pub fact. Lego is the worlds biggest tyre manufacture wonder what there tolerances are lol.
