I installed a high end wheel cover on my 2014 CR-V. The wheel cover is a good quality leather like some of those shown. It came with the thread, needles, tape, scissors and a tucking in tool. The job went fine, and the tucking in tool worked flawlessly around the radio control module on the left and the cruise control on the right. Appearance wise, much better than standard covers.
Behind these two control modules (The rear of the wheel spokes, if you will) have nowhere to tuck or sew. This is the area where your fingertips would be as you grip the wheel.
The leather did not lie flat and was wrinkled to the feel. I tried dozens of things to get this to lie down and feel smooth. Crazy glue didn't stick to the cover, I didn't try the gel, which may have worked better. The double sided tape furnished was not worth the bother.
I finally solved the problem with a strip of Blue Tack (Purchased at an office supply store) placed under the unfastened edge. I had all the time I needed to work it down with my fingertips.
I am almost positive that I haven't explained the problem and cure well enough to make sense to someone not tackling this job, but I hope those of you that have find this cure, easy, inexpensive and not destructive to the wheel or cover.
