    What is written on the side of the tyres you have now? Probably something like 60-406 or 406-60 ? – Criggie Mar 15 '21 at 07:26

20x2.175 may be some arbitrary numbers on a rim, but it isn't a size or measurement.

Reasonable widths for a 2.4 start at around 23mm inner width or 28mm outer. This includes what most would consider all real street/dirt/park rims. Plenty of frames and forks in the world won't take a 2.4. Most of the time it's fairly straightforward to predict that based on the clearance you have now. It can also easily be a case where you have to dial the chain length to make it work.
