my issue with run-flat tires is the roads and the locations and seasons that I drive on a regular basis
- runflats can be run flat at max 50 mph for a maximum time of ????? - I want to say 1 hour but it might be more
- runflats can be easily damaged when run flat so that a tire shop cannot repair the flat
- X3's have a sensitive x-drive system that works best when all 4 tires have the same depth and style of tread
- hence, replacing a runflat tire means buying 4 new runflat tires
- I drive on highways between provinces where there is a distance of 400-600 miles between major centres that would carry run-flats in stock at a reasonable price.
- if I had a vehicle with runflat tires I would have 5 tires/wheels and rotate the five regularly to keep them all about even tread depth.
If I am packing around a spare (5th tire/wheel) then why bother with the extra cost of runflats. Also I drive where it is winter 6 months of the year and a summer or allseason runflat will just not cut it for the snow season.... and I like to have a little tire sidewall to provide some cushion so a conventional tire is preferred over a low profile runflat on a larger diameter wheel
... all that added up says I will stick with good quality conventional tires and avoid runflat tires all together.
... forty-three years of driving before I get behind the wheel of a BMW .... and I am thinking, "why did it take me so long?"
... and then after another 4 years I can't believe that I have two of them !!
