Best wheels ?

[adz600]

hi all been looking at wheels and tyres for what seems like forever and still unsure, looking to build my first heavy will be 2 wheel drive at rear, front mounted axe and hopefully some kind of grabbing jaws

2x high power scooter motors, 2 in consideration 750w and 100w both 36v, similar too tomahawks motors

wheels gearing should not be a problem as i am planning to use t8f chain which is used on small mopeds and large electric scooters etc has a good load capacity for size of around 670 lbs depending on grade.

here in lies the problem,
go kart wheels - wide lots of grip, heavy and requires lots of work to fit
10 inch faom filled barrow wheel - easy to fit and cheap, narrow tread ,plastic hub weak large od
heavy grade castors - cheap , strong, easy to fit, narrow tread

any ideas greatly welcome
thanks adam

We make ours from ali bar and have Vulcalon bonded on, just means you can have whatever diameter and width of tyre you want.

They all have their merits, I personally like kart wheels as they give a ton of grip, I shoved 4wd robots with my kart wheels but they are difficult to build into a design simply due to the size

I'd get some strong castors like these:

And then just double them up to increase the tread width. Cheap, light, strong, grippy and can't be punctured.

while this thread is here i might as well ask what do everyone think is the best tyre material for grip, egc- rubber, polyeurathane ? want to get the grippiest available and must have bearings fitted.

found some nice trolley wheels 260mm foam filled high grip and cheap £12 for 2

next question done some maths based on the motor rpm etc

max speed at proposed gearing is 13.56 mph with no losses

too quick or about wright ?????????????????????????????

What motors, controllers, batteries are you using?

[adz600]

1000 watt scooter motors
not sure on batts yet depends on available space and funds
probably ncc70

[blazerbotics]

I would gear abit lower, 4QDs aren't the smoothest of controllers, if its too fast you will struggle to drive it.

would these 9amp 12volt batteries be ok, as they are quite light at 2.5kg each
