I've just found some old Maxxis Minion DHF Super Tacky tires (dual-ply) in the back of my cupboard that must be 5-6 years old.
I haven't used them for a while because I use something a bit lighter for UK riding. However, I am heading to Whistler in July, and I was thinking of resurrecting them for the trip as I got a few punctures last year with my Spesh Clutch SXs.
The questions is: Do tyres like that go off? They still have enough tread on them.
