Do you need a steering wheel cover for a leather steering wheel?

I do not know when to start, our new car to buy, we will default to buy and install the steering wheel handle, especially the relatively cheap car or some van, more keen to install the steering wheel handle, summer installation of the so-called leather steering wheel, the winter on the installation of the furry steering wheel, although this is more comfortable to drive, but a larger and thicker steering wheel handle seriously affects the steering wheel grip, so I personally do not like to install the steering wheel handle, but I do not like to install the steering wheel handle, so I do not like to install the steering wheel handle. So I personally don't like to install steering wheel cover.
