ITP introduced its SD Series beadlock wheels in 2013 as a lightweight but heavy-duty option for ATV and UTV racers. SD stood for “Severe Duty,” reflecting a design intended to keep a tire secured to the wheel during racing, rock crawling and other demanding off-road use.
The original lineup included both single- and dual-beadlock designs. The 14-inch SD Dual Beadlock secured the tire at both the inner and outer beads, while the 12-inch SD Single Beadlock paired an external beadlock ring with ITP’s reinforced inner wheel lip.
ITP SD Dual Beadlock Wheel
The 14×7-inch SD Dual Beadlock was promoted as the industry’s first lightweight, one-piece aluminum-alloy dual-beadlock wheel. By mechanically securing both sides of the tire, it provided what ITP called “Total Tire Security.”
A conventional beadlock clamps the tire’s outer bead between the wheel and a removable ring. ITP’s dual-beadlock design also secured the inner bead, reducing the chance of either side separating from the wheel when operating at low pressure or after suffering tire damage.
That capability was particularly valuable in racing, where keeping a damaged tire attached could allow a driver to continue to a pit or finish line instead of stopping on course.
ITP SD Single Beadlock Wheel
The original 12×7-inch SD used a conventional outer beadlock ring and ITP’s “Rock Armor” reinforced inner lip. The design provided much of the low-pressure security associated with a beadlock while avoiding the added hardware of a second locking ring.
ITP later expanded the SD Single Beadlock line with 14×7- and 15×7-inch versions. Those larger sizes became especially relevant as performance UTVs moved toward taller tires and 15-inch wheels.
SD Series Construction and Features
- Cast aluminum-alloy construction
- Single- and dual-beadlock configurations
- ITP Rock Armor reinforced wheel lip on single-beadlock models
- 12×7-, 14×7- and later 15×7-inch sizes
- Multiple ATV and UTV bolt patterns
- Matching ITP center cap
- Two-year limited warranty against bending or breaking when introduced
ITP used its Advancecast manufacturing process to balance wheel strength with relatively low weight. That was particularly important on early sport UTVs, which had considerably less horsepower than today’s machines and were more sensitive to increases in rotating and unsprung weight.
UTVGuide Experience with the ITP SD Wheel
The SD Series eventually became more than a press-release product for UTVGuide. We ran 15-inch ITP SD beadlocks with 32-inch UltraCross R Spec tires on our 2016 Polaris RZR XP Turbo project, using the combination for dirt, desert and rock-crawling trips.
We also paired the SD Series wheel with the same tire in our 32-inch ITP UltraCross R Spec review. At the time, a 32-inch tire was unusually large for a recreational UTV, making wheel strength and bead retention particularly important when running reduced pressures in rough terrain.
Is the Original ITP SD Series Still Available?
Current-product update: The original SD Single and Dual Beadlock wheels are no longer prominently listed in ITP’s current online product catalog. Some sizes and bolt patterns may still be found through retailers as remaining inventory, but availability varies considerably.
ITP now lists the newer SD10 Beadlock Wheel among its current wheel offerings. Buyers considering an older SD Series wheel should confirm the size, offset, bolt pattern, replacement-ring availability and load requirements before ordering.
A Notable Early UTV Beadlock
The original SD Series arrived while UTV performance and tire sizes were advancing rapidly. Its combination of lightweight aluminum construction, reinforced wheel lips and available dual-beadlock security made it a notable option for early UTV racers and aggressive recreational riders.
Although newer wheel designs have since entered the market, the SD Series helped establish ITP’s presence in the performance UTV beadlock category—and its durability was proven on several of our own UTVGuide project vehicles.
