It sounds like the nosewheel is skidding (applying too much tiller angle before the turn rate builds up). Taxying in MSFS isn't great (it's improved a lot in FS24 apparently). You must make tiller inputs slowly or the nosewheel will skid. Only make tight turns with GS less than 10 knots.
Nosewheel skidding will happen in a real airliner if you apply too much tiller too quickly. So this is a realistic effect and you need to keep tiller inputs slow and only increase the tiller as the turn rate builds up. I find setting reactivity to 0 in the tiller axis helps as it responds slower.
