Wyton's runway was re-done far more recently than Scampton's. I cannot say what state it's in, but I would estimate that it would be good enough for 558 - bear in mind that 558 will be operating at light weights, not the max t/o AUW that it used to operate.
Besides, the Nimrods were using it until about 11 years ago, and then it was in very good condition, having been completely refurbished in the mid-80s.
Perhaps a PPruner who uses Wyton would be able to comment?
