You can pull them but will need and eraser wheel or some goo gone and a a plastic scraper to get the adhesive tape off..easiest way is an eraser wheel on a drill
Good choice on wheels..tahoes look really good on sierras 99-02 Silvys imo
looks sick the way it is, kinda cool to see a dropped truck with all the stock stuff on and white walls lol. But will look way cleaner with all that stuff off
