Swapping knobby off-road tires for street rubber is one of the best upgrades you can make to an electric dirt bike you ride on pavement. A smooth or semi-slick tread gives you a bigger contact patch (up to 30–50% more rubber on the road), quieter rolling, steadier braking, and even a 5–10% bump in battery range. But which set should you buy? We're comparing three popular options: our own WocoMotors Electric Dirt Bike Street Tire Set (Front & Rear), the 12 Inch Supermoto Wheels Set sold on Amazon, and the Yozma IN 10 Pro Street Tires from Yozma's official store.

Weight
- WocoMotors Street Tire Set 12": ~6.3 kg total (rubber‑only rear tires)
- Supermoto Wheels Set (Amazon): ~11.7 kg total, complete assembled wheel pair (rims, tires, rotors, sprocket, spacers included)
- Yozma IN 10 Pro Street Tires (OEM): ~6.7 kg total, OEM rubber‑only rear tires
Compatibility
This is the single most important factor, and it's where the three products diverge sharply. The 12 Inch Supermoto Wheels Set has the broadest explicit compatibility list: Yozma IN10, IN10 Pro, Heybike, Tuttio Soleil01, Mototec, VALTINSU EM5, Razor MX350, MX650, and ETM Rtr. Because it replaces the entire wheel assembly (rim, tire, rotor, sprocket), it sidesteps the question of whether your existing rims accept a particular tire bead.
The Yozma IN 10 Pro Street Tires sit at the opposite end of the spectrum. They are OEM parts designed exclusively for the IN 10 Pro, which runs a 12-inch front and 14-inch rear setup. If you own any other bike on the list above, these tires simply will not fit.
Our WocoMotors Street Tire Set is engineered for dual-sport electric dirt bikes running 12-inch rims, the most common pit bike standard. That covers a wide range of machines, though you should always confirm your rim width and bead diameter before ordering. If you're unsure, our support team can help you verify fitment.
Winner: 12 Inch Supermoto Wheels Set, thanks to its long confirmed compatibility list and the fact that it brings its own rims.
What's in the Box
The Amazon kit is the most comprehensive package by a wide margin. You get gravity-cast aluminum one-piece wheels (15 mm inner / 35 mm outer bearing), pre-mounted Kenda Curve semi-slick tires, two 190 mm brake rotors, a 420-48T rear sprocket, and the small axle spacer needed for rear-wheel fitment. It is a true supermoto conversion kit.
Both the WocoMotors set and the Yozma set are tire-only packages. You mount them onto your existing rims, reuse your current rotors and sprocket, and ride. That's a simpler job, but it also means your rims, rotors, and sprocket stay as-is, for better or worse.
Winner: 12 Inch Supermoto Wheels Set for sheer completeness. If your existing wheels and rotors are in good shape, though, a tire-only swap is all you need.
Installation Difficulty
A tire-only swap (WocoMotors or Yozma) is straightforward if you have tire levers and a bit of patience, or a local shop that can mount them in minutes. You pull the wheel, break the old bead, seat the new tire, and bolt the wheel back on.
The Supermoto Wheels Set is a bigger project. You're replacing the entire wheel assembly, which means swapping the rear axle sleeve and making sure you don't lose the included axle spacer. It's not rocket science, but there are more steps and more parts to keep track of. Riders who aren't comfortable with brake rotor alignment or chain tension adjustment may want a mechanic's help.
Winner: WocoMotors Street Tire Set and Yozma IN 10 Pro Street Tires (tie). Tire-only swaps are simpler and faster.
Pavement Performance
All three options accomplish the same core goal: replacing aggressive knobby tread with a smoother pattern that grips asphalt better, brakes more predictably, rolls quieter, and wears slower on paved surfaces. Electric dirt bikes deliver peak torque at zero RPM, so the rear tire takes an immediate, hard shove every time you twist the throttle. A proper street compound handles that load with less squirm than a knobby.
The Supermoto Wheels Set uses Kenda Curve semi-slick tires, a well-known compound with a strong reputation among mini moto and supermoto riders. The WocoMotors set is built for superior paved-surface grip and stable highway handling. The Yozma set is OEM-matched to the IN 10 Pro's geometry and suspension tuning, which can matter for riders who want a factory-validated feel.
Without head-to-head lap data on identical bikes, it's hard to crown a clear winner here. All three will be a dramatic improvement over knobbies on pavement.
Winner: Tie. Any of these sets will transform your street ride.
Versatility and Off-Road Capability
Let's be honest: once you bolt on street tires, you lose roughly 30% of your loose-terrain traction compared to knobbies. None of these sets is meant for serious trail riding. If you split your time between dirt and pavement, you'll want to keep your stock knobby wheels and swap back and forth.
The Supermoto Wheels Set actually makes this easier in one way. Because it's a complete wheel assembly, you can keep your original dirt wheels intact and switch between the two sets without remounting tires each time. With a tire-only swap (WocoMotors or Yozma), you'd need a second set of rims to do the same thing, or you'd be breaking and reseating beads every time you change terrain.
Winner: 12 Inch Supermoto Wheels Set, because it lets you maintain two complete wheel sets for quick swaps.
Value
Exact pricing can shift, so check current listings before you buy. In general, a tire-only set costs less than a full wheel conversion kit. The WocoMotors Street Tire Set and the Yozma set are both tire-only packages, so they'll typically come in at a lower price point. The Supermoto Wheels Set includes aluminum rims, rotors, and a sprocket, so it commands a higher price, but you're getting significantly more hardware.
If your existing wheels are beat up or you want the convenience of a second complete wheel set, the all-in-one kit can actually save money compared to buying tires, rims, rotors, and a sprocket separately. If your wheels are fine and you just need fresh rubber, a tire-only set is the smarter spend.
Winner: Depends on your situation. Tire-only sets (WocoMotors or Yozma) win on upfront cost. The Supermoto Wheels Set wins on total value if you need the full package.
The Verdict: Which One Should You Buy?
If you own a Yozma IN 10 Pro and want a guaranteed OEM fit, the Yozma IN 10 Pro Street Tires are the safe pick. They're sized for the Pro's 12"/14" wheel setup and validated by the manufacturer. Just know they won't fit any other bike.
If you want a full supermoto conversion with fresh wheels, rotors, and sprocket, the 12 Inch Supermoto Wheels Set on Amazon is the most complete kit. It fits a long list of popular electric dirt bikes, and the Kenda Curve tires are proven performers. The trade-off is a higher price and a more involved install.
If you ride a 12-inch-rim electric dirt bike and just need quality street rubber without replacing your entire wheel assembly, our WocoMotors Electric Dirt Bike Street Tire Set is the move. It's a straightforward tire swap that delivers the grip, quiet rolling, and range gains you're after, at a price that reflects the fact that you're buying tires, not a whole new wheel system. And because we're a factory-direct operation, you get competitive pricing, fast shipping, and real support if you have fitment questions.
No matter which route you choose, ditching knobbies for street rubber is one of the highest-impact upgrades you can make for pavement riding. Your braking distance shrinks, your ride gets quieter, and your battery stretches further. Pick the set that matches your bike and your budget, and enjoy the road.
