Choosing RC repair tools & parts usually comes down to fit, not the number of choices: do you need a crawler tire in a particular wheel format, or a drivetrain part with a precise gear specification? The comparison below covers two 1.9-inch tire sets, one 1.3-inch tire set, and one pinion-gear set. Start with scale, wheel format, and the dimensions or gearing named for your repair, then use price as the tie-breaker.
Quick take
- For 1:10, 1.9-inch crawler tires: The BFGoodrich Mud-Terrain four-piece set names Axial SCX10 ii 90046 and Traxxas TRX4 compatibility, plus a 90mm outside diameter.
- For a 1.9-inch tire with larger stated dimensions: The 4PCS rubber set lists a 120mm height, 50mm width, 48mm inner diameter, and 1:10 crawler use.
- For 1.3-inch beadlock wheels: HOBBYSOUL specifies 72mm-tall by 28mm-wide tires with a soft, sticky compound.
- For an 1:8 drivetrain repair: NHX RC provides 32P, 5mm-bore pinion gears in five tooth counts from 13T through 17T.
Listed-price comparison
The listed prices run from $19.95 to $36.26, a $16.31 spread. The bars make the relative position easy to scan; part type and fit still matter before price becomes the deciding factor.
| Product | Listed price | Price bar | Fit or purpose |
|---|---|---|---|

Decision matrix
- Match a 1:10 crawler with 1.9-inch rims and a 90mm outside diameter: Choose the BFGoodrich Mud-Terrain set.
- Match a 1:10 crawler with a 120mm-by-50mm tire profile: Choose the 4PCS rubber set, whose fit details name Axial SCX10 ii 90046 and Traxxas TRX4.
- Use 1.3-inch beadlock wheels on mud, loose dirt, or slick rock: Choose HOBBYSOUL for its 72mm-by-28mm format and soft sticky compound.
- Replace or adjust a pinion in an 1:8 drivetrain: Choose NHX RC when 32P and a 5mm bore are the required specifications.
Product notes
BFGoodrich Mud-Terrain 1.9-inch RC Crawler Tires
The BFGoodrich Mud-Terrain four-piece set is a focused choice for a 1:10 crawler using 1.9-inch rims. It is specified for Axial SCX10 ii 90046 and Traxxas TRX4, and the tire size is paired with a 90mm outside diameter. Choose it when that named wheel format and diameter match the replacement you need. The limitation is the defined 1:10, 1.9-inch, and 90mm combination, so it is not a general answer for a build using another tire or wheel format. The title also identifies a Mud-Terrain pattern, making the intended crawler-tire role clear without confusing it with a drivetrain repair part.
HOBBYSOUL 1.3-inch Griptrek RC Crawler Tires
HOBBYSOUL's four-pack targets a 1.3-inch beadlock-wheel setup. The tires are specified as 72mm tall and 28mm wide, with an asymmetric irregular triangular tread and a super-soft sticky compound described for mud, loose dirt, and slick rock. Choose it when the 1.3-inch wheel format and 72mm profile fit the crawler's setup. The limitation is that specific beadlock format: shoppers working with 1.9-inch wheels need to focus on one of the other tire formats here. The 72mm-by-28mm dimensions also make the physical profile a central part of the decision, rather than a detail to ignore.
1.9-inch Rubber RC Crawler Tires for 1:10 Traxxas TRX4
The 4PCS 1.9-inch rubber tire set is another 1:10 crawler route, with fit details naming Axial SCX10 ii 90046 and Traxxas TRX4. It specifies a 120mm tire height, 50mm width, 48mm inner diameter, black color, and 104g per tire. Choose it when the 1.9-inch format and those measurements align with the build. Its limitation is the stated 120mm-by-50mm profile, which makes dimensional fit especially important for a replacement. The title's TRX4 reference and four-piece count make the intended use easy to identify, while the rubber construction and grip emphasis keep the focus on tire replacement rather than a tool.
NHX RC 32P 5mm-Bore Pinion Gears
NHX RC's 32P pinion set is the drivetrain-focused pick in the group. The title specifies a 5mm bore, hardened steel construction, and five tooth counts: 13T, 14T, 15T, 16T, and 17T. It is listed for 1:8 scale. Choose it when the repair calls for a 32P pinion with a 5mm bore and a way to select among those tooth counts. The limitation is its narrow specification: scale, pitch, bore, and tooth count all need to match the intended drivetrain. It is a component set, not a tire pack or a broad collection of RC repair tools.
Final recommendation by use case
- For a 1:10, 1.9-inch replacement with a 90mm outside diameter: Choose the BFGoodrich Mud-Terrain set.
- For a 1:10, 1.9-inch replacement matching 120mm by 50mm dimensions: Choose the 4PCS rubber tire set.
- For a 1.3-inch beadlock setup: Choose HOBBYSOUL and its 72mm-tall, 28mm-wide format.
- For an 1:8 pinion repair: Choose NHX RC when the 32P, 5mm-bore specification matches.
If price is the tie-breaker after fit, NHX RC has the lowest listed price and HOBBYSOUL the highest, with the $16.31 spread separating the two ends. The correct choice still depends on the wheel format or drivetrain specification named above.
