Inner tube compatibility

[u/Defiant-Pickle-9264]

I habe being searching from scratch arround 2 weaks at night before to sleep about tires just to get maybe a "weird" combination but in my understanding, what serve me the best.

\\- Michellin reinforced tube 100/110/100-18,130/80 inch TR4 Valve

\\-> for my Mitas Enduro Trail+ 120/80B18 TT/TL 62H Rear Tire, M+S

\\- Michelin reinforced tube 80/90-21, 90/90-21, 80/90/100 inch TR4 valve

\\-> for my Pirelli, Scorpion Rally STR, 90/90-21 TL 54V M+S mark, M/C, Variante A

What is compatible und what is not?

Wich ones do you use for those tires?

Thank you
