INJORA King Trekker Tires Review

INJORA King Trekker Tires Review

Small RC crawlers need tires that can grip uneven rock, hold their shape on side hills, and still fit under tight micro bodies. The INJORA King Trekker Tires & Inserts Combo is made for that exact decision point. This review looks at the 1.0-inch 62 x 22 mm King Trekker tire and silicone insert combo, sold as four tires with four inserts.

The main draw is the complete package. You get INJORA S5 rubber, staggered center lugs, reinforced side lugs, bias ply construction, and silicone rubber inserts in one set. The main tradeoff is size, because a 62 mm tire can rub on some 1/18 and 1/24 crawler bodies if your setup has limited fender or suspension clearance.

Key Specs

What Is the INJORA King Trekker Tire & Insert Set?

The INJORA King Trekker combo is a tire and insert set for small RC crawlers. It includes four 1.0-inch rubber tires and four yellow silicone rubber inserts. Wheels are not included, so you need separate 1.0-inch crawler wheels that work with your build.

The tires measure 62 mm tall and 22 mm wide. That makes them taller than many stock micro crawler tires, which can help with ground clearance and a more planted stance on obstacles. The tradeoff is body fit, because tall tires can contact fenders, bumpers, sliders, or the body at full steering lock.

The design is aimed at technical crawling instead of high-speed use. The S5 compound is meant to feel soft and sticky, while the staggered lugs, reinforced side lugs, and silicone inserts help the tire stay useful when the crawler is climbing, leaning, or crossing uneven terrain.

Who Should Buy It?

Key Features

INJORA S5 Compound

The King Trekker uses INJORA S5 rubber. The listing describes it as super soft and sticky. On a micro crawler, that softness matters because the tire can flex around small edges and keep more tread in contact with rock or hard-packed dirt.

The benefit is better grip at slow speed. The limitation is that very soft crawler tires can feel less precise if your rig is heavy or if your inserts do not support the sidewall well. That is why the included silicone inserts are an important part of this combo.

Staggered Center Lugs

The center tread blocks are staggered to add more biting edges during climbs. This helps when your crawler is moving over uneven rock shelves, broken roots, and rough trail surfaces where a smooth center tread could slip.

The layout is most useful when you drive slowly and let the tire work. On smoother indoor surfaces, the aggressive tread may not feel as necessary as it does on natural rock or loose outdoor terrain.

Reinforced Side Lugs

The side lugs are designed to improve side-hill stability and off-camber control. When your crawler leans over, the outer tread and sidewall carry more load. More side lug support can help the tire bite instead of folding away from the obstacle.

This does not make the truck rollover-proof. Your crawler weight, wheel width, insert firmness, and suspension setup still matter. The King Trekker simply gives you a more trail-focused tread shape than many basic stock micro tires.

Bias Ply Construction

The listing describes the tire as bias ply. For a crawler tire, the goal is to balance flexibility with enough structure for repeated use on rough surfaces. That matters when the tire is flexing over sharp edges, ledges, and angled rock faces.

Bias ply construction also fits the tire’s slow-speed use case. This is not a high-speed tire upgrade. It is built around grip, tread movement, and controlled contact on technical lines.

Silicone Rubber Inserts

The included silicone rubber inserts measure 58 x 17.2 mm and are listed at 12 g each. They are meant to support the tire better than a loose or overly soft foam insert, especially when the crawler is side-hilling or the weight shifts to one corner.

Silicone inserts can help the tire keep a more consistent shape. That can improve the contact patch and reduce sidewall collapse. The tradeoff is that insert feel is personal, so drivers who tune foam firmness for competition may still prefer a separate insert setup.

Fit and Compatibility

The King Trekker is a 1.0-inch tire, so it is intended for 1.0-inch crawler wheels. Fit still depends on the wheel’s bead design, width, and how the silicone insert sits inside the tire. Some wheels may mount more easily than others.

INJORA lists the set for small crawlers such as the 1/24 Axial SCX24 and AX24, 1/24 FMS FCX24, 1/18 FMS FCX18, 1/18 Traxxas TRX4M, 1/18 Redcat Ascent18, and other micro crawlers. That does not guarantee perfect clearance on every build. Body style, wheel offset, axle width, shocks, ride height, and steering angle can all change the fit.

Setup Tips Before First Use

Start by comparing the 62 mm outer diameter with your current tire. A small increase in tire height can change gearing feel, center of gravity, and body clearance on a micro crawler. If your current setup already sits low, expect more fit checking.

When mounting the tires, make sure the silicone insert sits evenly inside the casing. A twisted insert can create uneven sidewall support and make the tire wobble or feel lumpy. After mounting, roll the tire by hand and check that the bead is seated evenly around the wheel.

Once installed, test the truck slowly before heading to difficult terrain. Check for rubbing at full steering lock, full suspension compression, and side-hill lean. If the tire touches the body, you may need a small trim, a body height change, a different wheel offset, or a smaller tire.

How It Performs in Real Use

For Rock Crawling

On rock, the King Trekker’s strongest traits are the soft S5 compound, staggered center lugs, and 62 mm height. The rubber can conform around small edges, while the tread blocks add bite during slow climbs. The taller diameter can also help the axle clear some small ledges.

For Side-Hilling and Off-Camber Lines

The reinforced side lugs and silicone inserts matter most when your crawler leans sideways. The insert helps support the tire so it does not fold too easily under load. That can make the truck feel more controlled on off-camber lines, though your wheel width and weight placement still affect stability.

For Loose Dirt, Roots, and Mixed Trails

The open tread and aggressive lug layout can help the tire find traction on loose dirt, roots, and rough mixed surfaces. It should be viewed as a technical crawling tire, not a deep-mud tire. On very wet or packed mud, a small 1.0 tire can still clog or lose bite.

For Tight Micro Bodies

The 62 mm height gives the tire a more aggressive look, but it can also create clearance problems. Compact hard bodies, low-mounted bodies, and narrow fenders are the setups most likely to rub. For those builds, a 57 mm tire may be easier to live with.

What Buyers Are Saying

At review time, Amazon showed a 4.8 out of 5 star rating from 68 global ratings. Because rating counts can change, treat this as a snapshot rather than a fixed long-term number.

• Praise: Several reviewers mention strong traction and a sticky feel.
• Praise: Buyers also mention good side bite and useful performance on different surfaces.
• Watch-out: Amazon’s visible review summary showed one negative traction mention, but it did not show a clear repeated complaint theme.

Material Safety and Compatibility Notes

The tires are rubber, and the inserts are silicone rubber. The listing also states a manufacturer minimum age of 14 years. That matters because small RC parts are not suitable for younger children, and the tires, inserts, and wheels can create small-part risks during setup or storage.

Use the tires for RC crawler applications only. Keep loose inserts and unmounted parts away from young children and pets. Follow your vehicle and wheel maker’s instructions when mounting tires, and do not force a beadlock wheel together if the tire or insert is not seated correctly.

Pros and Cons

Is It Worth the Price?

The King Trekker combo is worth considering if you want both tires and silicone inserts in one package. The value comes from the full set: four S5 compound tires, four silicone rubber inserts, reinforced side lugs, and a 62 x 22 mm size for more aggressive micro crawler builds.

It offers strong value for the price if your current stock tires lack grip or sidewall support. You get the most value if you already own compatible 1.0-inch wheels and want to tune a crawler for slower technical terrain.

It is less compelling if you already own inserts, need a smaller tire, or want a pre-mounted wheel and tire set. In that case, compare the total cost of tires, inserts, and wheels before buying.

How It Compares to Alternatives

INJORA 1.0″ Swamp Claw M/T Tires: Consider these if you want a more mud-focused tread pattern in the INJORA 1.0 lineup. They may make more sense for loose, messy trails than for clean rock crawling.

INJORA 1.0″ 57 x 22 mm Rock Terrain Tires & Silicone Rubber Inserts Combo: Consider this option if you like the tire-and-insert idea but need a shorter INJORA tire for builds with tighter body clearance.

Pro-Line Racing 1/24 Hyrax Front/Rear 1.0″ Tires Mounted on Black Impulse Wheels: Consider this type of setup if you want a pre-mounted SCX24 tire and wheel option instead of separate tires and inserts. The King Trekker makes more sense if you already have wheels and want to choose your own wheel setup.

Frequently Asked Questions

The Bottom Line

The INJORA King Trekker Tires & Inserts Combo is a strong option for micro crawler owners who want a soft 62 x 22 mm 1.0 tire with added sidewall support. The S5 compound, staggered lugs, reinforced side lugs, and silicone inserts make the most sense for technical crawling on rocks, roots, loose dirt, and off-camber lines.

Buy it if your crawler has room for a 62 mm tire and you want tires plus inserts in one set. Skip it if you need wheels included, need a smaller tire, or want an exact verified tire weight with no listing conflict.
