FAQ

Are these the 4.19" or 4.75" KM3 tyres? These are the smaller Class 1 version measuring 4.19" (106mm) in outside diameter and 1.42" (36mm) wide. Pro-Line also produces larger KM3 variants, so check the part number and dimensions carefully when ordering.

Will these fit standard 1.9" crawler wheels? Yes. They are designed for 1.9" crawler wheels and are compatible with Pro-Line's range of suitable 1.9" wheels. Fitment with third-party beadlock wheels can vary, so check the wheel manufacturer's specifications where required.

Are these suitable for Class 1 crawler builds? Yes. At 4.19" tall, this version was specifically designed around the popular Class 1 tyre size while retaining realistic BFGoodrich KM3 proportions.

What is Pro-Line G8 compound? G8 is Pro-Line's proven crawler tyre compound designed to provide a balance between off-road traction, predictable handling and durability. It is a great all-round choice for trail and scale crawling.

How do they perform on rocks and trails? The aggressive tread blocks and flexible construction provide strong traction across rocks, dirt, leaves and mixed trail surfaces. Their relatively compact Class 1 dimensions can also help reduce tyre rubbing compared with larger 4.75" crawler tyres.

Are foam inserts included? Yes. One foam insert is supplied for each tyre, so the pair is ready to mount to compatible 1.9" wheels.

How many packs do I need for one crawler? Each package contains two tyres. A typical four-wheel crawler therefore requires two packs.

Important Notes

• Package contains 2 tyres only; purchase 2 packs for a typical four-wheel crawler.
• Wheels are not included.
• These are the 4.19" Class 1 KM3 tyres, not the larger 4.75" KM3 version.
• Check tyre clearance at full steering lock and full suspension compression before driving.
• Beadlock fitment can vary between wheel manufacturers; confirm compatibility when using non-Pro-Line wheels.
• Tyre performance can vary with vehicle weight, foam setup, terrain and temperature.
• Vehicle and wheels shown in promotional images are sold separately unless otherwise stated.
