How Does it Work?
We designed Rim Saver to take the edge off of sharp impacts that lead to rim cracks, dings, and pinch flats. It spreads out and absorbs impact energy to protect your wheels and tires. Our design decisions are guided by computer simulations, test lab data, and extensive real-world ride testing to ensure it keeps you riding.
It's important to remember that no tire insert will make your wheel indestructible, but it certainly helps to take the edge off.
Spreading Out the Impact
Sharp rocks hit hard and fast, and your tire struggles to absorb the impact. This sends most of the force straight to the rim, which can crack, dent, or cut the tire.
Using the engineering principle of Stress = F/A, Rim Saver spreads the impact force over a larger area, reducing stress on the rim. It takes the sharpness out of the hit, turning it into a softer, more manageable impact, something your rim and tire are much better at handling.
Absorbing the Impact
Rim Saver’s engineered polymer absorbs impact like a stiff spring. Unlike foam inserts that can compress, degrade, and lose effectiveness, Rim Saver stays durable and only deforms under serious impacts, ensuring long-lasting protection.
The key is stiffness. A stiff spring absorbs sharp impacts better than soft foam, which can be sliced on the rim during sharp impacts. Rim Saver follows another engineering principle: Force = kx, where k is stiffness and x is deformation. Its high k-value allows it to absorb big hits with minimal deformation, providing protection against sharp impacts.
This protects both your rim and tire. Rim Saver not only spreads out sharp hits for your rim but it does the same for your tire’s sidewall, helping prevent pinch flats.
Engineered & Tested
We combine real-world ride testing with lab testing to ensure our product performs as we want it. We utilize computer simulations, including Finite Element Analysis (FEA), to analyze and optimize designs before ride testing.
To take it a step further, we built an in-house impact testing machine to rigorously evaluate Rim Saver’s strength and performance. This machine allows us to simulate and replicate real-world impacts while correlating design changes to actual performance. By combining cutting-edge simulations, controlled lab tests, and extensive field testing, we ensure every Rim Saver is ready to protect your rims where it matters most.

Why is Rim Saver Easier to Install?
Our patent-pending bungee system increases Rim Saver’s diameter during installation, allowing it to move out of the way of the tire beads. Once the tire is mounted, Rim Saver cinches itself into position, always held in the right place to absorb impacts and protect the rim.deformation, providing protection against sharp impacts.
This protects both your rim and tire. Rim Saver not only spreads out sharp hits for your rim but it does the same for your tire’s sidewall, helping prevent pinch flats.
Lightweight
Rim Savers protective material is only where it’s needed, allowing us to use less material while still providing excellent protection. Not only is Rim Saver lightweight, it feels lightweight when riding as it's not squishing during rolling and keeps your tire feeling peppy.
Fast Ride Feel
Unlike many foam inserts, Rim Saver doesn’t deform as your tire rolls. This means no energy is wasted by squishing foam on every tire rotation. Instead, all your pedal power goes into moving you forward, not deforming your tire insert. It feels like there’s no insert at all.
No Sealant Absorption
While you can compare the dry weights of tire inserts, foam inserts often absorb tire sealant over time, making them heavier and requiring you to add more sealant to keep your tires inflated. Rim Saver doesn’t absorb sealant, so it stays the same weight from day one.
Easy to Live With
Rim Saver is easy to install, remove, and helps extend the life of your wheels and tires, reducing the work needed to maintain your bike. Rim Saver doesn’t change in feel over time, so you don’t have to adjust your riding style as the insert breaks in or wears out.
