What to do if steering wheel is made out of pig’s skins
Tanning means treating the skin with chemicals or leaving it out in the sun to purify it and to remove any smell, decay or dampness. (Maraqi Falah p.66)
In the Hanafi Fiqh, skins of all animals besides pigs are Tahir (pure) after going through the process of tanning. Saaiduna Zaid Bin Thabit narrates from the Prophet of Allah ‘Tanning the skin of the dead animal is its purification’. (Sahih Ibn Hibban & Darul Qutni)
Leather is generally made from the skin of cattle’s whereas suede leather is made from the underside of skin. Primarily it is made from lamb though it may also be made from pigs, calves and deer’s.
With regards to your question if the steering wheel is made out of normal leather then it will be permissible to use. Steering wheels predominantly are made from skins from cattle’s. However, if by chance it is made from suede leather which used pig’s skin then you have two options:
Put a cover around the steering wheel.
Change the steering wheel.
