INJORA 120MM 1.9" Rubber Rock Tyres Review: Are They Worth the Upgrade?

We’ve all been there. You’re out on the trail with your favorite RC crawler, you find a challenging rock face or a patch of loose dirt, and your truck just spins its wheels. It’s frustrating. Stock tires are fine for the backyard, but once you start getting serious about technical crawling, you realize pretty quickly that rubber compound and tread pattern make a massive difference.

If you’ve been searching for a tire upgrade that won’t break the bank, you’ve likely stumbled across the INJORA 4PCS 120MM 1.9" Rubber Rock Tyres Wheel Tires for 1:10 RC Crawler Car Axial SCX10 90046 AXI03007 TRX4 Redcat Gen8. I’ve been testing these on my own rigs for a while now, and I’m ready to give you the honest breakdown. Are they actually good, or are they just cheap? Let’s find out.

What Are the INJORA 120MM 1.9" Rubber Rock Tyres?

At its core, this is a set of four oversized, aggressive crawler tires designed for 1.9-inch wheels. If you own a popular 1/10 scale crawler like the Axial SCX10, Traxxas TRX4, or Redcat Gen8, these tires are built to fit your existing rims.

The main appeal here is simple: value. RC tires from "name brand" companies can cost as much as a small dinner for two. These INJORA tires offer a budget-friendly way to change the look and performance of your truck without needing a massive budget. Plus, because they are widely available on sites like Amazon or direct from their site, you can often find them with free shipping, which makes the deal even sweeter.

Key Features That Actually Matter

When you’re out on the rocks, you don’t care about marketing buzzwords. You care about grip. Here is how these tires actually perform in the wild:

The Size Factor At 120mm, these are quite tall. This gives your truck extra ground clearance, which helps you climb over obstacles that would normally hang up your axles. The added height also gives the truck a more "scale" look, making it look like a real-life custom build.

The Rubber Compound The rubber is significantly softer than what comes standard on most "Ready-to-Run" (RTR) kits. This is a good thing. Soft rubber conforms to the shape of the rocks, grabbing onto edges rather than sliding over them. You’ll notice the difference immediately when you start climbing steep inclines.

Tread Pattern The tread design is aggressive. It features deep lugs that act like claws in loose dirt and mud. They do a great job of clearing out debris, so you don’t end up with "racing slicks" after the first five minutes of driving through wet grass or mud.

Real-World Performance: The Good and The Bad

I spent a weekend putting these to the test on a mix of granite rocks and loose, sandy trails. Here is the honest truth about how they hold up.

The Pros

Excellent Grip: For the price, the traction is genuinely impressive. They handle rocky terrain much better than standard plastic-like stock tires.
Easy Installation: They mount up to standard 1.9-inch beadlock wheels without much of a fight.
Aesthetic Appeal: They make almost any crawler look more aggressive and "pro-level."
Price: You get a full set of four for a fraction of what premium brands charge.

The Cons

Foam Inserts: The included foams are okay, but they aren't the best. If you are a competitive crawler, you might find them a bit too soft or inconsistent. Some users prefer to swap them out for dual-stage foams later on.
Not for Speed: These are heavy, soft, and tall. If you try to bash your RC car at high speeds, you’ll notice they wobble and deform. These are strictly for slow-speed crawling.
Glue vs. Beadlock: If you aren't using beadlock wheels, gluing these can be a bit messy because of the deep tread pattern near the bead area.

Who Is This For (And Who Should Skip It)?

You should buy these if:

You’re on a budget. You want better performance but don't want to spend $80+ on high-end tires.
You’re a weekend warrior. If you go trailing once or twice a month and want your truck to look and perform better, these are perfect.
You’re new to the hobby. If you just got your first SCX10 or TRX4, this is a great "first upgrade" to learn how different tires affect your driving.

You should skip these if:

You are a competitive pro. If you are entering serious crawling competitions, you will likely want specialized, high-dollar tires with custom-tuned compounds.
You bash your car at high speeds. These tires are built for crawling, not for jumping or high-speed driving.

What Other Users Are Saying

To make sure I wasn't just biased, I looked at what others were saying about this INJORA 4PCS 120MM 1.9" Rubber Rock Tyres Wheel Tires for 1:10 RC Crawler Car Axial SCX10 90046 AXI03007 TRX4 Redcat Gen8 review sentiment online.

“I put these on my Redcat Gen8 and the difference in grip was night and day. They aren’t the softest tires I’ve ever owned, but for the price, I’m not complaining. They look awesome and handle the local trails just fine.” — Mark S.
“Good tires for the money. The foams were a little squishy for my heavy TRX4, but I swapped them for some firmer ones and now they work great. Definitely worth it if you want an affordable upgrade.” — Sarah L.

Final Verdict: Is It Worth the Money?

After putting these tires through their paces, my final verdict is that they are a fantastic value. Are they the absolute best tires on the planet? No. But they aren't trying to be. They are trying to be a reliable, grippy, and affordable option for people who want to enjoy their hobby without spending a fortune.

If you are tired of your stock tires slipping and sliding on every rock you see, the INJORA 120MM 1.9" Rubber Rock Tyres are a solid choice. They offer a great balance of performance and style, and the fact that you can often snag them with free shipping makes them an easy recommendation for any RC enthusiast looking to level up their rig’s capabilities.
