Bought one Big Apple for the back of a tandem some time ago thinking the massive volume would give a bit of suspension / bounce, it worked really well.
Sine moved it onto the back of my No2 bike, initially as I use the bike on rollers and the slick tyre is quiet. The bike gets used on all terrain and actually the Big Apple is remarkably good.
I ride hardtail so that bit of bounce is good, not a single puncture in 12 months and the grip is brilliant on tarmac, good on trails, not tried it in mud but I guess we all know what the result would be.
The reflective ring on the side wall is very effective.
If you are intending to run these tyres do check your rear stay clearance, they are seriously big and would not fit in many frames.
Overall, I would buy another one.
