§ 02 / About this part

What it is

The PARTS UNLIMITED 18" STANDARD BUTYL TUBE TR-4 STEM TYPE FITS 3.50/4.00, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This standard butyl tube is a workshop essential for 18-inch rear wheels. It fits 3.50 to 4.00 width tyres typical of enduro and trail bikes. The TR-4 straight metal stem is durable and easy to access with a pump. Always use a fresh tube when fitting a new tyre to avoid punctures from old, stretched rubber. Apply plenty of tyre soap or talc during installation to prevent nips from tyre levers. Keep one in your pack for emergency trail-side repairs.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. Brands you'd find on a paddock workbench — pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere; dirt and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
