Flat tires, bald treads, and cracked rims turn mowing day into repair day. Simplicity tires and rims take the beating—rocks, rough terrain, sun damage. When your mower bounces, bottoms out, or won't grip, genuine OEM Simplicity tires and rims restore stable footing and proper ride height. Repair Clinic carries the exact sizes and specs your model needs.
Don't compromise on wheels. Genuine Simplicity tires match your mower's weight distribution and deck height requirements. Mismatched or undersized tires throw off blade leveling and can damage your transaxle. We stock front and rear assemblies, individual tires, and rims—all OEM, all backed by our parts help ensure.
Your Simplicity model number is your key. Check the frame badge, then browse our Simplicity lawn mower tire and rim parts to find front and rear wheel assemblies. Need a size confirmation? Our lookup guide pulls the right part in seconds.
Tires and rims are easy to overlook until your mower starts riding rough or won't hold air. Small wheels do big work on Simplicity mowers, and understanding what's wearing out helps you buy with confidence.
Simplicity front and rear tires come in different sizes—commonly 13x5.00-6 (front) and 20x10.00-8 or 23x10.50-12 (rear), though it varies by model. Size affects blade leveling, steering feel, traction, and engine load. A smaller or larger tire throws off deck height and can make your mower cut unevenly. Always match your OEM size exactly—your model number and owner's manual will confirm the spec.
Under normal residential use, expect 5–10 years or 100+ hours of mowing before tread wears smooth. Sun exposure and storage conditions speed deterioration—tires left outside year-round fail faster. Even if tread looks okay, cracking or hardness signals time for replacement. OEM Simplicity tires are built for your mower's weight and blade load, so they outlast generic alternatives.
Small sidewall punctures should be replaced—patching risks reoccurrence and uneven wear. Tread punctures *can* be patched if the hole is under ¼ inch and not near the edge, but Simplicity tire assemblies are affordable enough that replacement is often smarter. A bad patch can go flat mid-mow, leaving you stranded. OEM replacements are the safe, reliable choice.
Undersized tires cause your deck to sit lower, hitting obstacles and potentially scalping your lawn. Oversized tires sit higher, affecting blade depth and making the mower harder to control on slopes. Wrong sizes also increase stress on your transaxle and wheel bearings, shortening part life. Stick to OEM specs—it's the foundation of safe, even cutting.

On Simplicity lawn mowers, look for the model number on a badge attached to the frame near the blade deck, under the seat, or on the engine housing. Clean away grass and dirt so the letters and numbers are easy to read, and copy the entire model designation exactly, including any dashes or suffixes. Type it into our model number lookup and the catalog narrows to parts made for your unit. This filters the full Simplicity lawn mower parts selection, not just tire and rim parts, so you can compare compatible parts for the mower as a whole. Using the model number up front saves time and helps prevent ordering a part that does not fit.
