W Wellshine Luggage Wheels Protector - 8 Pack Silicone Suitcase Caster Covers for Most Luggage and Office Chair Wheels - No Noise, Black

Value for money and very useful

This product will protect your wheels all right, but you probably will miss your flight! The protective rubbers have massive friction with the floor and it takes twice the effort, energy and time to move your suitcases. Would skip. Else prepare to skip your flight.

They fit really well with the wheels. Easy to put on. The material is thick. Works really well.

These wheele covers slip off after long use

These are probably the thinnest wheel covers I've tried so far, but they do stretch pretty well so they might do ok for travel. One aspect that I am not too keen on is the boring light gray color which will also no doubt get very dirt once used on the road. I would prefer something brightly colored for conspicuity if they are going to get dirty anyway. We'll see how it goes.
