Which truck tires for hobby drivers?

Hello, we have in the company an Iveco MP190 tipper, the car also has a Hiab 195-4 with Jib, which is actually interesting for us. So mostly the vehicle is used as a crane truck i.e. it was only moved around 6000KM, the rest is crane hours and standstill. Now it is so that he drives mainly in local transport as well as sometimes an hour highway. Now he has installed on the front axle Matador 315 80 22.5 M tyres this but A slowly go to the end and B has a At the flank a small crack (looks like scratched with cutter knife) However, you still have 3mm profile (don’t know if they are still good or not). But I intend to buy new ones in the next weeks but absolutely baffled what I should buy, the question arises to me whether at the low mileage/year a retreaded go????? Steering axle? And it should of course be all weather! Who can give me reasonable advice ?
