<p class=""><strong>18″ x 8.50″-8 Pneumatic Wheel with Mini 4-Stud Rim and Golf Buggy Tyre (PN18-850-8MN)</strong></p>
<p class="">This compact wheel assembly is built for smooth, reliable performance on motorised golf buggies and turf vehicles. It features an 18×8.50-8 golf buggy tread tyre pre-fitted to a Mini 4-stud pattern steel rim (101.6mm PCD) with a zero offset, providing centred load distribution and easy bolt-on compatibility.</p>
<p class="">Designed to minimise surface impact while maintaining grip on grassy terrain, the tyre’s turf tread pattern is ideal for both flat and uneven courses. With a 4-ply rating and a max load of 350 kg at 22 psi, this assembly offers a balance between strength and surface sensitivity.</p>
<p class="">The full assembly includes the premium turf tyre and steel rim—making it a convenient replacement or upgrade option for a wide range of buggies.</p>
<h3>Mini 4-Stud Mounting Pattern</h3>
<p>A Mini 4-stud mounting pattern offers a compact stud layout that suits lightweight hubs and wheels. The Mini mounting pattern features 4 bolt holes on a 101.6mm (4”) circle. It contains 4 studs evenly spaced around the rim of the wheel and provides easy installation and alignment.</p>
<p>This mounting pattern is commonly found on small trailers, compact mowers, golf buggies, and turf equipment.</p>
<h3><strong>Zero Offset Rim</strong></h3>
<p>A zero offset wheel means that the mounting point of the hub is in the centreline of the rim. This means the wheel is mounted equally spaced and balanced between each side of the rim for maintaining a balanced load distribution across the hub.</p>
<p>This type of offset is common in rear golf buggy wheels, trailers, and turf equipment.</p>
