Run-Flat Tyre Insert — Bolt-On Segmented Nylon, 15 in to 22.5 in Wheels

About this product

A run-flat insert is a ring of high-strength segmented nylon that bolts together inside the tyre, around the wheel. With the tyre inflated it does nothing; when the tyre is punctured, shot out or shredded, the vehicle settles onto the insert and keeps driving — steering, braking and accelerating with control — instead of stopping where it is. That is the difference between a vehicle that gets its passengers out of a situation and one that becomes part of it, which is why inserts of this type are standard on cash-in-transit, VIP protection, government, NGO field and expedition vehicles worldwide.

What you get

• Bolt-on segmented run-flat insert, high-strength nylon composite, supplied in segments with fasteners and fitting hardware
• Fits inside the standard wheel and tyre — no special wheel needed, tyre size must match the insert size
• Available for 15 in to 22.5 in wheels; 16–22 in from stock sizing, 15 in and 22.5 in on request
• 12-month manufacturer warranty
• Sold per insert; a vehicle needs one per wheel (plus spare if required)

Who it is for

Security and VIP transport, cash-in-transit, government and embassy fleets, NGO and mining field vehicles, ambulance and emergency response, and serious overland and expedition 4×4 builds where a flat tyre in the wrong place is not an option. Drake SVO can supply inserts alone or as part of a full vehicle power and protection package.

Sizing and fitting

Tell us the wheel diameter and tyre size (e.g. 265/65 R17) for each axle and we will confirm the insert size and quantity. Fitting requires the tyre to be removed from the wheel; we can recommend fitters in Thailand or supply fitting guidance for your own workshop.
