A wear extender is presented for use with planters, air seeders and drills that utilize the engagement of a flexible wheel with a disc to scrape mud from the side of the disc. The wear extender is formed of an ultra-high molecular weight plastic that is compression molded. The wear extender is generally cylindrical in shape and when installed covers the interior edge of the tire. Installation of the wear extender extends the life of the tire and reduces the need to replace the tire. In addition, due to the more-rigid nature of the wear extender as compared to the more-flexible nature of the tire, the wear extender does a better job of scraping mud than the tire. As such, use of the wear extender reduces the number amount of downtime that occurs due to poor scraping and reduces the amount and cost of maintenance due to tire wear.
