HOBBYSOUL 1.3 Tires Review: Soft Micro Crawler Tires for SCX24 and TRX4M Builds
By: Single Product Backpack Team
Last updated: June 15, 2026
HOBBYSOUL 1.3 tires are made for micro crawler owners who want more grip on slow technical lines. The article details list a 1.3-inch rim fit, 72mm height, 28mm width, and a soft sticky compound for rocks, roots, mud, and mixed trail surfaces. They are aimed mainly at 1/24 SCX24 and 1/18 TRX4M style builds, but clearance should be checked before buying.
Verdict
These tires make the most sense for micro crawlers that need slow-speed grip on rocks, roots, loose dirt, and muddy patches. The larger 72mm height can help ground clearance, but it may also require body or fender clearance checks on some rigs.

What Is This Product?
The HOBBYSOUL 1.3 tire set is a four-pack of micro crawler tires for 1.3-inch wheels. The listed size is 72mm tall and 28mm wide, which makes them a tall tire option for small-scale crawler builds.
The main focus is traction. The soft sticky compound is meant to help the tire bite into uneven surfaces instead of spinning quickly on rock, roots, loose dirt, and muddy trail sections.
Who It Is For
- SCX24 owners upgrading to 1.3-inch wheels
- TRX4M owners who have room for a 72mm tire
- Drivers who crawl slowly on rocks, roots, loam, and mud
- Builders who want more side bite from an asymmetrical tread pattern
- Hobbyists who are comfortable checking body, bumper, and fender clearance
Who Should Skip It
- Buyers who need tires already mounted on rims
- Drivers who want a tire mainly for high-speed running
- Micro rigs that cannot clear a 72mm-tall tire without trimming
- Owners using wheels that are not made for 1.3-inch tires

Soft Sticky Compound
The soft compound is the key grip feature. It helps the tire conform to uneven surfaces, which can improve contact on rocks, embedded roots, and broken trail sections. Soft rubber can also wear faster than harder compounds, so these are better suited to crawling than long high-speed sessions.
Asymmetrical Tread Pattern
The asymmetrical tread pattern is designed to add predictable side-to-side bite. That matters when a crawler is turning on angled rocks or crossing roots where the tire needs to hold a line instead of sliding sideways.
72mm Tall Profile
The 72mm height can help a small crawler roll over ridges and trail obstacles. The trade-off is fit. Check the body shell, fenders, links, shocks, and bumper area before assuming the tire will clear through full steering and suspension travel.
1.3-Inch Rim Fit
These tires are made for 1.3-inch rims. They are not a direct fit for every stock micro crawler wheel. Confirm wheel size before buying, especially if your crawler still has its original wheels.
Real-World Use
These tires are best used on slow technical crawls. They fit the kind of driving where throttle control matters more than speed. On wet rock, dry stone, roots, and muddy ruts, the soft compound should help the tread stay engaged when the crawler is moving slowly.
On loose sand or fine gravel, the wider 28mm profile can help the tire stay more planted. Grip will still depend on vehicle weight, insert choice, wheel setup, and how gently the driver applies throttle.
For setup, focus on wheel inserts and tire cleanliness. Softer support can help the tire wrap around rock, while firmer support can sharpen steering and reduce sidewall fold. Clean mud and dust from the tread after runs so the compound can keep making contact with the surface.
Pros and Cons
Pros
- Soft sticky compound is aimed at slow technical grip
- Asymmetrical tread can help with side bite and line control
- 72mm height can improve rollover on small trail obstacles
- Four-tire set works for a full micro crawler tire swap
Cons
- Tires only, so wheels are not included
- 72mm height may require trimming or clearance changes on some bodies
- Soft compound can wear faster if used for hard or high-speed running
- Fit depends on 1.3-inch wheel compatibility
Is It Worth the Price?
The value depends on your current wheel setup and clearance. If your crawler already runs 1.3-inch wheels and has room for a 72mm tire, this set is a practical traction upgrade for rocks, roots, mud, and mixed trail surfaces.
It is less attractive if you still need to buy wheels, inserts, or body clearance parts to make the tires fit. In that case, compare the full setup cost, not just the tire set.

Frequently Asked Questions
Do HOBBYSOUL 1.3 tires fit SCX24 crawlers?
They are listed for 1/24 SCX24 style builds, but fit depends on the wheels and body clearance. Confirm that your crawler has 1.3-inch wheels and enough room for a 72mm-tall, 28mm-wide tire.
Do they fit TRX4M crawlers?
They are also aimed at 1/18 TRX4M style setups. The main checks are rim size, fender clearance, steering clearance, and suspension travel.
Are rims included?
No. The article details describe the product as a set of 4 tires for 1.3-inch rims. Wheels are not included.
Are these good for wet rocks and roots?
Yes, that is one of their main uses. The soft sticky compound is meant to help with bite on rock, roots, and mixed trail surfaces. Keep the tread clean for the best contact.
Are they good for high-speed driving?
They are better suited to crawling than speed. Soft crawler tires can heat up, flex, and wear faster during long high-speed runs. Use them for slow control and technical traction.
Will they work with foam or beadless inserts?
They should work with properly sized 1.3-inch micro crawler inserts, but fit depends on the wheel and insert shape. Check the inner tire shape, wheel bead area, and sidewall support before final assembly.
Do they need body trimming?
Some builds may need trimming or clearance changes because the tires are 72mm tall. Check full steering lock and suspension compression before running them on the trail.
Final Verdict
HOBBYSOUL 1.3 tires are a good match for micro crawlers that need more soft-compound grip on rocks, roots, mud, and mixed terrain. Their 72mm height and 28mm width can help on technical lines, but those same specs make clearance checks important. Buy them if your rig is ready for 1.3-inch tires and your main goal is slow-speed traction.
