REDSPIDER 0.7 Cling On Crawler Tires - 40mm OD x 16mm for SCX30, Redcat Ascent-32, 1/30 1/32 RC Crawlers

The REDSPIDER 0.7 Cling On Crawler Tires are an upgrade option for 1/30 to 1/32 scale RC crawlers like the SCX30 and Redcat Ascent-32. These tires measure 40mm outer diameter and 16mm width, with a 0.7-inch rim size. They are designed with an ultra-soft adhesive rubber compound and an asymmetrical open tread pattern to grip loose dirt, mud, and uneven surfaces. Compatible with most 0.7 beadlock wheels, they come with factory-size foam inserts for a straightforward setup that requires no trimming.

Built for Micro Crawling

These tires use a soft rubber that flexes to match terrain contours, helping maintain contact on rocks and roots. The material is formulated to stick to slippery surfaces, giving you more control when navigating tricky lines. The internal foam insert is sized to fit the tire cavity without needing modifications, so you can mount them directly onto your existing wheels.

Tread and Traction Details

• Open tread design – The wide gaps between lugs allow mud and debris to clear out, keeping the tread clean for continuous bite in loose conditions.
• Reinforced center blocks – The middle section has larger tread blocks that provide stable forward traction, especially useful during steep climbs and side-hill traverses.
• Asymmetrical pattern – The layout of the lugs is different on each side to optimize grip in both forward and reverse, improving maneuvering in tight spaces.

Quick Answers

Do these tires fit the stock SCX30 wheels?

They are designed for 0.7-inch beadlock wheels. If your SCX30 has stock wheels that are 0.7 beadlock style, they will mount directly. Otherwise, you may need aftermarket wheels.

Do I need to trim the foam or tire?

No. The tires come with a factory-sized foam insert that requires no trimming. Just mount them on compatible 0.7 beadlock wheels and you are ready to crawl.

Are these tires suitable for mud and loose dirt?

Yes. The open tread pattern is specifically designed to bite into and clear loose surfaces like mud, gravel, and soil, giving you better traction in those conditions.

What is the load capacity?

Each tire has a load capacity of 2.2 pounds, sufficient for typical micro crawler weights.
