A set of plastic, standard length trim removal tools, is just not going to be long enough to assist with the removal of these aero covers unfortunately.
Using a long pry bar that has the shank / blade covered by protective film, does appear to be a favoured option by some.
This offers the opportunity to slide the pry bar behind the trim and start the process of levering back on the retaining tabs, that can be unwilling to initially “let go” of its grip on the spokes of the alloy rim behind.
Focussing on one small section of the trim first and then pulling back hard with your hands, can result in the trim cracking / splitting.
Other people have said they had no problem in removing these trims.
It has been suggested that by using both hands simultaneously and then by pulling with equal force, they should release without causing damage by splitting / cracking.
Pulling back on the wheel cover in a single location, appears to be the incorrect approach.
