i would check tirerack for the explanation for the speed ratings.
as for running runflats.. not a 'problem' but they do run stiffer and usually heavier than the standad tires. also not to add more confusion but there use to be RE050A Pole Position which were grippier than the starndard RE050A's dat came on the Z.
but considering u're just looking for a pair of tires to get you by this season, i wouldnt sweat it.
