You should look for name brand kart tires. Lecont, Vega, MG, Hoosier. You won’t find either on aliexpress. Look for karting focused webshops. All tires should be 10x4.5-5, if you buy full kits you receive 2x that and 2x even bigger tires which aren’t good for esk8 use.
Before you buy any rims, find some wheelhubs first that support esk8 pulley mounting patterns - there aren’t many options at the moment (I’ll be making some in a month or two). I don’t think traditional belt setups will work with these, open gear is your only safe bet right now, until I get to making some enclosed gear drives for them (few months). After you got hubs look for rims that fit those hubs and have a 5" diameter, and somewhere around 5" width.
Also anything less than 12mm axle on your trucks and I can almost guarantee you’ll bend them. You need strong trucks. And then you’ll also need to extend the wheelbase of your board otherwise you’ll have wheelbite.
