Given Southeastern’s comment that he has two 104XL (rear) and two 100W (front), I have just double checked mine for peace of mind given that I had previously looked closely at only the front pair (as all four distinctly said “Bridgestone”).
I can confirm that all four of my tyres are the same Bridgestone Alenza 001 (100W) tyre, and my ride is satisfactory, but my dealer also tells me I also have factory fitted upgraded shocks. Having suffered the horrible ride over minor carriageway defects of low profile run-flats on my past Mercedes, I imagine the reinforced 104XL could well be similarly harsh.
