Seem to be averaging around 8K miles
. Very little long distance stuff lots of twisty country roads and some town, with a fairly punishing style of driving

Read an article recently that the runflats wear quicker and will be changing to non-runflats with the next set. Wanted this anyway because of the reported extra handling (due to non runflats being a lot lighter) and extra comfort. Seems to be a real consensus of opinion on the forums about the benefits of the none runflats.
