Learn when to replace your Red Jumper 2 rear tires, how to fit the 370202012 set with rims, and what to check before your first run.
Quick answer
Replace the rear tires on your Carrera Red Jumper 2 when you see worn tread, cracks, or poor grip, and use the 370202012 set of two rear tires with rims for a direct fit. The process takes minutes: remove the old wheels, check the axle and hub, mount the new set, and test the car at low speed.
Why rear tires wear faster and when to replace them
Rear tires on the Red Jumper 2 take the drive force and most of the acceleration load, so they often wear faster than the fronts. Check the tread depth and sidewalls before each session. Replace the pair when the tread is visibly thin, the rubber feels hard or cracked, or the car spins easily on surfaces where it used to grip. Replacing both rear tires at once keeps handling balanced; mixing a worn tire with a new one can make the car pull or lose traction unevenly.
What the 370202012 set includes and why rims matter
The Carrera 370202012 set includes two rear tires already mounted on rims. That saves you from separating old tires from rims and reduces the chance of pinching a new tire during installation. Because the rims are included, you can keep your old set as a spare or inspect the old rims for damage after removal. If your current rims are cracked or the hub is worn, the new set solves both issues at once.
Step-by-step rear tire replacement
- Power off and remove the battery: Switch off the car and disconnect the battery before you touch the wheels. This prevents accidental acceleration while your hands are near the drivetrain. Never skip this step; a live RC car can start unexpectedly.
- Lift the rear axle and secure the car: Place the car on a stand or block so the rear wheels spin freely. Check that the axle spins without binding before you remove anything. If the axle feels rough, inspect bearings or bushings before installing new tires.
- Remove the old rear wheels: Take off the wheel nuts or retaining screws, then pull the old tires and rims straight off the axle. Keep the hardware in a tray so you do not lose it. Do not pry against the axle; pull evenly to avoid bending the hub.
- Clean the axle and check for play: Wipe any dirt or grass from the axle ends and inspect for side-to-side play. A worn hub can make new tires wobble. If the axle moves noticeably, fix the wear before fitting new wheels.
- Mount the new tires with rims: Slide each new rear tire onto its axle, aligning any flat spot on the rim with the axle pin or flat. Push until fully seated, then refit the nut or screw. Do not overtighten; the wheel should spin freely with no rocking.
- Spin-test by hand: Rotate each rear wheel by hand and watch for wobble or rubbing against suspension parts. The tire should turn smoothly without contact. A rubbing tire will overheat and wear quickly; adjust or re-seat it before running.
- Reconnect and test at low speed: Reinstall the battery, set the car on the ground, and run it slowly for a few seconds. Listen for unusual noise and check that both rear tires grip evenly. If the car pulls to one side, recheck that both wheels are fully seated.
