No press. No problem.
A segmented polymer RunFlat bolts together around the rim with hand tools — no hydraulic press, no specialist equipment. Any competent crew can do it.
Watch it go together — step by step.

Grease the inside of the tire
Install time is readiness time.
Every hour a wheel spends waiting on a hydraulic press at a depot is an hour that vehicle isn't available. Segmented polymer RunFlats move the entire job to wherever the vehicle is — your motor pool, a forward site, or our New Jersey facility if you'd rather receive complete assemblies.
- No capital equipment — a torque wrench replaces a press.
- Any competent crew — the procedure is simple enough to train in a single session.
- Reversible — unbolt, service, and re-use; segments swap without destroying anything.
- Or skip it entirely — order complete wheel assemblies from us, built, torqued, and ready to bolt on.
1. Grease the Tire
Apply the supplied long-life RunFlat grease uniformly around the inside tread — one tub per tire. This is the friction barrier the RunFlat rides on when the air is gone.
2. Drop in the Segments
Feed the three polymer segments through the tire bead and lay them around the inside of the tire, positioned either side of the valve location.
3. Connect the Segments
Fit the wedge bolts and clamping plates at each joint — double locking washers under every bolt head and thread adhesive on every bolt. Both locking methods, every time.
4. Torque to Spec
With the torque-limiting tool, tighten each wedge bolt in turn to the setting marked on the RunFlat identification label — then torque the clamping-plate bolts the same way.
5. Onto the Rim Base
Lower the tire-and-RunFlat assembly over the rim base and seat the lower bead. No press, no fitting rig — this is the step that usually needs a machine, done by hand.
6. Seat the O-Ring
Place the O-ring seal on the rim base before the outer half goes on. On a two-piece wheel, this seal is what holds the air — don't skip it, don't pinch it.
7. Bolt on the Outer Ring
Fit the outer ring over the studs and run the flange nuts down in a criss-cross pattern — hand-tight first, then in stages to the specified torque.
8. Inflate & Inspect
Inflate in a tire-inflation safety cage and check for leaks. Record the fitting in the vehicle log — batch number, date, fitter, mileage. Mission ready.
