UpGrade RC has expanded its tire lineup with two new 2.9-inch pre-mounted belted options, announced on July 2, 2026. The UPG-10035 Dirt Claw and UPG-10036 Street Radial are designed to fit the Traxxas Maxx, Arrma 4S Kraton, and other large-scale RC vehicles, covering both off-road and on-road use.
Dirt Claw: Off-Road Grip
The UPG-10035 UpGrade RC Dirt Claw 2.9″ Pre-Mounted BELTED Tire is built for rugged terrain. According to the announcement, it features a unique tread pattern, an advanced rubber compound, and tough multi-spoke wheels. The integrated belted carcass keeps the tire stable under high loads, reducing ballooning at speed. Each set includes two removable hex options for standard and wide wheel offsets, allowing drivers to adjust the stance without buying extra adapters.
Street Radial: Pavement Performance
For on-road bashing, the UPG-10036 UpGrade RC Street Radial 2.9″ Pre-Mounted BELTED Tire is designed for burnouts and fast cornering. The wide sipes help keep the tires cool and clear away water, dirt, and debris for consistent grip on streets, parking lots, and skate parks. Like the Dirt Claw, it comes with two removable hex adapters for offset flexibility.
Pricing and Availability
Both tire sets are priced at $49.99 per pair. The full UpGrade RC product line is available at local hobby stores and online at AMain Hobbies. The brand’s catalog now includes 426 products, covering tires, performance accessories, and graphics.
Brand Background
UpGrade RC is not a completely new name in the hobby. Forum discussions from early 2024 note that the brand has been around for about 20 years, originally producing high-quality decals and small CNC aluminum parts. AMain Hobbies revived the name and began rolling out pre-mounted tires and accessories. One design choice that has drawn attention is the use of sidewall vent holes rather than tread vents. Some RC enthusiasts have pointed out that sidewall vents can help preserve foam inserts and keep dirt from collecting inside the tire, though opinions vary on the optimal vent location.
What’s Included
Both the Dirt Claw and Street Radial come ready to run out of the box. The pre-mounted design eliminates the need for gluing or trimming tires onto wheels. The included hex adapters give users the option to run standard or wider offsets without additional parts.
Where to Find Them
UpGrade RC tires and accessories are sold through AMain Hobbies and local hobby retailers. The company’s full line of performance-driven products can be browsed at AMainHobbies.com, where the UpGrade RC brand page lists tires, decals, wraps, and aluminum upgrades.
With these two new releases, owners of Traxxas Maxx, Arrma 4S Kraton, and similar large-scale rigs have fresh, ready-to-run tire choices for both dirt and pavement. The sets are available now at $49.99 per pair through the usual hobby channels.
