Totally agree with Hannes. Even though my fronts were still a good 3 mm+ I changed all 4 at the same time. Bought from Blackcircles.com at £53 each and had fitted and balanced locally for £12 per tyre. Balancing can be an issue. I concluded that not every tyre fitter appreciates nor understands how wire wheels need to be balanced. It is essential that you use cones that hold the inner spoke rim away from the backplate of the balancing machine, so that the wheel is held in the same way as it sits on the splined axle of the car. Our local club have the correct cones, so I first took along my spare wheel with the cones to several local fitters to try out their machine. ( all very helpful and accommodating) However, some machines would show up an error code if the machine back plate could not "feel" the wheel pressed against it. I suspect if I had not actually witnessed the fitting and balance operations it would have been done any old how with a result that may or may not have been satisfactory depending on how much run out the wheel rim had.
