Air carrier Maintenance Controller reported they received a call from a Captain with an issue with a cut on a main landing gear tire. They placed it on an MEL and the tire was replaced on the return trip.

Narrative

Captain on Aircraft X to ZZZ called Maintenance Control when on the ground in ZZZ. They found a cut in the tread. They sent a picture of the tire in question. Myself and the other controllers on duty looked at the picture and did not feel that it was beyond limits of the AMM (Aircraft Maintenance Manual) 32-49-01-200-802-A (Trend cut limits). The crew did not have any more issues with the tire this was their second leg in the aircraft and I told them we would have ZZZ1 mx (Maintenance) follow up on the wheel when they got back. I made a software log event on the work in question and told them to be ready to change a wheel assy if they thought it needed it. My thought was have all the tools and parts ready instead of having to run back to the shop. We had approx an hour to prepare if needed. The Lead in ZZZ1 started with attitude which I tried to ignore but he got under my skin so I got out of the event. I do remember saying to the other controllers 'That Mother [Expletive] has just gotten the last bit help from me'. The week before he was asked to replace a seat belt on a different aircraft and made a big deal about parts and manual references. When I would ask questions I never got straight answers and I finally told him to '[Expletive] it' just retain the MEL. So as far as I am concerned he can pound sand. Maybe I could request I be put on the no deal with ZZZ1 mechanics list like another maintenance controls has with ZZZ1 mechanics. Sorry got on a rant there.When the aircraft got to ZZZ1 the mechanics sent a picture of tire cuts. I told them that is not the same as what the crew saw earlier. The Lead again gave me attitude about the aircraft being at an out station. I dropped in the picture the crew sent. The ZZZ1 guys jacked up the wheel and found the other cut. The mechanic I was working with said he would feel better if it was replaced. So that is what they did. And that is the reason I made the event to have it looked at.In Maintenance Control we get pictures all the time from crews asking question of is it okay or legal. We use our judgement and the AMM/CMM's (Component Maintenance manual) to come to the best; safest and legal decisions. I ground aircraft at out stations and bases very day I work I got no problems in letting them sit until they are repaired correctly. I am not going to jeopardies my license or other peoples licenses to move an aircraft that I knowing has a problem that is out of limits.
