After a bit of research, I guess the trick will be to find new traction bands!
I believe it is Premier. I can't find a model # on packaging or instructions.
I get it, we all started somewhere but I highly suggest you explore all the below resources and use them to your best advantage. Owning MTH is great, but you have to use the number system and also- know about the 2 main websites- https://mthtrains.com/ and https://www.mthpartsandsales.com/
#1 Know the MTH product number system. Premier starts with 20-xxxxx-x, and Railking is 30-xxxxx-x. You can then use that number to find ALL kinds of information on your engine.
#2 Know to use that number to look up your engine at MTH- this is where you get the manuals and example sounds files and other details about your engine. https://mthtrains.com/20-3032-1
#3 Know and use the MTH parts and sales website which has a TON of info to your best advantage- you own an MTH engine, you should know about this site. https://www.mthpartsandsales.com/
Here is the help files and tons of other helpful info https://www.mthpartsandsales.com/shop/documents
This is the MTH traction tires size chart that would tell you the correct part number or help you measure your rim to get the right tire size.

Also at MTH parts and sales, if I put your engine number into the "Exploded views parts Diagrams" search 20-3032-1
I get this complete list of parts specific to this engine with the "mechanical parts" link https://www.mthpartsandsales.c...lists/265?type=lists
near the bottom of the list part DE0000025
