the tire cost is part of the low price you pay! and before you even try the trailer you are already worried the tires are not the Best?
Kenda is a price pick by the factory , worry about wear on the
Next tire you buy.
Only Schwalbe tires in general ; they're all Good .. My LBS sells them for Touring bikes ..
want a long wearing tire a Suomi Nokian, Finland made Utility tire, uses a HARD Rubber mix..
I have a 20 year old set of studded Nokian tires on a bike I use when the road ices up (3 winters ago here)
Tracer HS 418 | Schwalbe North America
Or buy the schwalbe Marathon Plus model instead
you will find many more User revues of that model If you require that no risk 'you first, tell me how it went', shopping.
