Assuming the picture is what you got, I'd call the tire you got more of a 'block' tread than a knobby.... Knobbies usually will have much wider gaps between the knobs, say 50% or more 'space' than rubber.... The tires you show are fairly typical and probably a good compromise design for a scooter - and don't really have that much more space than the ones you are replacing....
I wouldn't expect them to have a lot of difference in life, and if there is, that is likely to be more an effect of the tire compound used than the tread design...
At scooter speeds, hydroplaning is essentially impossible no matter what tread design you have, as the water will have more than enough time to squeegee out from under them.... There isn't going to be any measurable difference in stopping and probably not much in traction. They may pick up a bit more crud if driving through mud.
Speed is a function of wheel rotation speed (RPM) and tire diameter. it has NOTHING to do with tread pattern as long as you are not spinning the wheels... Your RPM's aren't going to change.... If the new tires are larger in OD than the ones you are replacing, you might get a bit more speed, but if they are the same nominal size, the difference isn't going to be noticeable....

https://www.wheeliegoodmobility.co.uk/n ... ooter.htmlThe OEM tyres are radials but the tyres I received are knobblies.
But the tyres & tubes I received seem good quality.
But I'm concerned:
A) The knobblies will wear down really quickly on tarmac
B) They might not give enough grip on tarmac in the rain, seeing as I only ride on tarmac and 80% of that is riding on the road.
C) On the plus side I thought the knobblies being quite chunky will give me a smiggen more top speed?
