Wow, GP 4Seasons hard to mount? Mine have gone on to Fulcrum Racing 3s and DT R460s by hand, including a thoroughly miserable winter puncture (only puncture I've had on them after crashing over a pothole I hadn't seen) in the rain with numb hands.
Interested to hear they're not considered very good, is there something else considered durable but still relatively light, tough and fast rolling?
OP, apologies for the hijack!
I put mine on with a Kool Tool and had no difficulty. They just popped on.
I found the grip was ok but they had no suppleness. I raced them once just to get a better feel for them. Just done 150 km on GP 4000s and they are night and day different. Foundmounting to be easier than the GP4000s but I wouldn’t use them again.
Rode 650 km on the Paves over Christmas and they are so much nicer. The G Ones are also a better ride with a lot more volume and tubeless too.
