The aim of the disclosed solution is to present a method of inserting an insert to a tread a tire such that the insert, particularly a fragile insert such as an insert comprising electronic components, may be protected against gripping and impact forces during its insertion. The disclosed solution is premised on an insert being housed, at least partially, in a sleeve upon and during its installation to a tread of a tire. Thus, the sleeve may be employed to provide protection for the insert against gripping and/or impact forces during the insertion of the insert into the tread a tire.

A method for installing a stud in a tyre. The method includes identifying a stud hole for the stud in the tyre; imaging the vicinity of at least the stud hole, whereby information is received about the pattern in the vicinity of the stud hole, and using the received information to determine [i] the stud type suitable for the stud suitable in the stud hole and/or [ii] the suitable stud orientation of the stud suitable in the stud hole. The method includes providing a stud and installing it in a stud hole. The stud type of the stud is the same as the suitable stud type of a stud suitable in the stud hole; and/or the stud is installed in the stud hole in such a way that the main direction of the stud is parallel with the suitable stud orientation. Further a tyre studded by the method.
