The initial ELT means "End of Life Tyre" and indicates the mandatory contribution set out by Legislative Decree 82 of 11 April 2011 for the disposal of used tyres.
This contribution must be paid by the buyer and is collected by the dealer and paid to the respective consortium.
The ELT can also be paid when the tyres are mounted and therefore the assigned technician may request it. If they are purchased with Gommeh24.it, the paid amount is specified in the invoice and you only need to show it to prove the payment of the mandatory contribution.
