Obor Tires SPHINXX UTV Sand Paddle Tire
When your UTV bogs down on the dune face and the rear end washes out instead of digging in, you don't have a power problem — you have a paddle problem. The SPHINXX sand paddle tire from Obor is built to fix exactly that. Its Sand Digger tread runs 14 rear paddles with a full 1-inch paddle height to bite deep, displace sand efficiently, and turn engine power into forward thrust on Glamis, Dumont, Sand Mountain, and every dune in between.
Most paddle tires force a trade between thrust and weight. The SPHINXX uses a lightweight 4-ply carcass so you get aggressive propulsion without piling rotating mass onto your axles, which means quicker spool-up out of the bowl and less strain on your drivetrain.
Sold individually so you can set up your rear pair (or fronts) the way your machine and dune style demand.
Key Features
- Sand Digger Technology — excavation-style tread engineered to maximize traction and stability in soft, deep sand.
- 14 rear paddles — strategically spaced to displace sand and convert power into smooth, consistent thrust.
- 1-inch paddle height — deep scoop for strong acceleration and hill-climbing in the dunes.
- Lightweight 4-ply build — reduces rotating mass and UTV strain for faster, more efficient runs.
- 33-inch diameter on a 15-inch wheel — added clearance to float over soft, uneven sand.
- Two widths — 33x11 (WL77) and a wider 33x13 (WL78) for more paddle surface and bite.
Built To Solve
- UTV bogging down or losing momentum on the dune face.
- Rear tires spinning and washing out instead of grabbing.
- Weak thrust out of bowls and off the line in deep sand.
- Heavy paddle tires that bog the drivetrain and slow throttle response.
- Not enough float, causing the machine to plow rather than ride on top of soft sand.
Best For
- Dune riders at Glamis, Dumont, Sand Mountain, Little Sahara, and other sand parks.
- Sport SXS owners running a dedicated sand setup for weekends and dune trips.
- Riders who want strong propulsion without the weight penalty of a heavy paddle.
- Recreational dune carving through to dune racing.

Fitment
The SPHINXX is a sand/dune paddle tire mounted on 15-inch wheels and fits a wide range of sport side-by-sides set up for the dunes. Because paddle tires are a terrain-specific upgrade rather than a model-specific bolt-on, confirm your wheel diameter (15 in), bolt pattern, backspacing, and clearance before ordering. Verify intended width (11 in vs 13 in) against your fender and suspension clearance. Fitment is not guaranteed on unlisted or unverified wheel/clearance combinations.
Frequently Asked Questions
Will the SPHINXX stop my UTV from bogging down in deep sand?
That's its core job. The Sand Digger tread, 14 rear paddles, and 1-inch paddle height are designed to dig in and displace sand so engine power becomes forward thrust instead of wheel spin, which is what keeps you from bogging on the dune face.
Why is the SPHINXX lighter than other paddle tires, and does that hurt durability?
It uses a lightweight 4-ply carcass to cut rotating mass for quicker acceleration and less drivetrain strain. The 4-ply build still balances flexibility with the strength needed for repeated hard dune sessions.
What wheel size does the SPHINXX require?
Both sizes are 33-inch tires built for 15-inch wheels — the 33x11 uses a 7.0AT rim and the 33x13 uses a 10.0AT rim. Confirm your bolt pattern and backspacing match your machine before ordering.
What's the difference between the 33x11 and 33x13?
The 33x13 (WL78) is wider with more paddle surface, a higher 675 lb max load, and weighs about 31 lbs, giving more bite and float; the 33x11 (WL77) is narrower at 598 lb max load and about 22 lbs for a lighter setup. Many riders run the wider, heavier-biting size in the rear for thrust and the lighter size up front.
How much do the SPHINXX tires weigh?
The SPHINXX is built light: the 33x11 (WL77) comes in around 22 lbs and the wider 33x13 (WL78) around 31 lbs. That lightweight carcass cuts rotating mass, which reduces strain on your UTV and lets you accelerate harder and ride more efficiently across the sand.
How do I install and break in the SPHINXX?
Mount on a properly sized 15-inch wheel, balance, and set pressure no higher than the 14 psi max — most dune riders run lower for a bigger footprint. Watch the install video below and confirm torque specs for your machine.
Is the SPHINXX good for trails and hardpack too?
No — it's a dedicated sand paddle tire. Running paddles on hardpack, rocks, or pavement wears them quickly and reduces control. For mixed terrain, look at the Obor Lynx or Predator instead.
Why Obor
Obor builds side-by-side and ATV tires tested in demanding off-road conditions, from cross-country racing to the dunes. The SPHINXX brings that engineering focus to sand with purpose-built Sand Digger paddle technology, so dune riders get propulsion, float, and durability in one lightweight package.
