I thought your car would be on run flats?
I personally find the Pirelli's OK, although they do like to track tarmac imperfections. I'd never heard of Rapid and if you can why not run with all Goodyear to see if that corrects the issue, also run a couple of PSI lower in the front if steering feel is a priority.

Hi Steve
Tyres are or can be a touchy subject with some seeing them as a necessary evil and buy cheap others only buy the best. Certainly seems someone put cheap ditch finders on for either MOT or sale.
Personally I like same make front and rear and go for the recognized brands so I would check the rear wear and make a decision based on their condition. If they are good or nearly new condition I would buy the same for the front.
The last set on my X5 are Bridgestone before was Yoko's and before that Michelin as I look for the deals, my winter wheels have Witrac Extreme fitted.
