Sound Suzuki Swift (gear??)

Hello together, maybe someone can help me from you. Vehicle: Suzuki Swift Built 2007 The vehicle was this week during the big inspection (about 100,000 km). The workshop master informed that some bearings or a warehouse had to be changed, otherwise there might be a gear damage. Apparently more often occurs when wider tyres are raised…When driving one hears a dull “brumming”. Can any of you do anything with this statement?? Unfortunately I can’t Name further details, since I don’t know them myself… Thank you!!
