HPI Savage 21/25 JAE 40 Series Tire w/ Insert by 3Racing HSA-032  [HSA-032]

1/8 Monster Truck Tire with Insert

This is a pair of replacement tires designed for 1/8 scale monster trucks, presented as a set for hobby use. The tyres include removable foam inserts to help control sidewall flex and maintain consistent contact patch under cornering and landings. Intended uses include general off-road practice, backyard bashing, and setup tuning where tyre choice affects handling balance.

Compatibility is stated for Savage 21 and Savage 25 platforms and for 1/8 monster truck applications listed by the seller. The design focuses on straightforward fitting to common 1/8 rims and on providing a predictable feel rather than any single performance claim. The product is supplied as 1 pair (pcs).

Installation and tuning notes

Mount each tyre on the wheel ensuring the bead seats fully; use tyre glue if your rims require permanent attachment. Fit the provided insert concentrically to avoid uneven wear, and consider thicker or thinner foam if you seek different sidewall stiffness—changes in insert firmness affect traction, rebound over bumps, and how the truck behaves in jumps. Check wheel hex fitment before high-speed use.

Materials and handling

The tyre compound and foam insert are selected to balance durability and grip for hobby-level off-road use. Store tyres away from direct sunlight and ozone sources to limit premature hardening. Inspect bead and sidewall for damage after hard impacts and replace if the structural integrity is compromised.
