Bear-Cut: 

Tire reprofiling

effortless, fast & sustainable!

Extending the life of your tyres and saving CO₂

Quick and easy regrooving (regrooving) of commercial vehicle tires with the regroovable label.

Life extension of at least 25 %

Regrooving a tyre and extending its life by at least 25% means buying fewer new tyres.

Positive for CO₂ balance and wallet

A regrooved tyre consumes less fuel, which has a positive effect on the CO₂ balance and on the wallet.

Bear-Cut.
Now with improved technology.

Bear-Expander

New clamping system:

What our clients say

Gerhard Röger

Stefan A. Eisenhofer Transporte

Before the seasonal tyre changes, we always re-groove for three months straight. Before the Bear-Cut, using the handheld device, we did about four tyres every day. After that, we had to stop, as the strain on the shoulder was very noticeable. Working with the machine is much more comfortable. You’re still fit in the evening.

Alexander Schuon

Alfred Schuon GmbH

Schuon stands for sustainability, which is why we continuously optimize eco-efficiency across all processes. The Bear-Cut fits perfectly into our sustainability strategy.

Andreas Oppel

Spedition Oppel GmbH

By regrooving with the machine, the downtime of our vehicles is reduced, and the workshop bays become available more quickly for other tasks. We expect the investment in the machine to pay off for us within five years.

Thomas Oppel

Spedition Oppel GmbH

We have been regrooving our tires for a long time, but up to now only with conventional handheld tools. However, since this is a very time-consuming task, we were looking for a way to increase the number of tires we can regroove per year without adding extra workload for the team.

Peter Lüdorf

Gummi Berger Gruppe

Gummi Berger’s customers receive premium tires from us and therefore expect premium services – for example, to maximize the mileage of their high-quality casings while reducing fleet operating costs and lowering their carbon footprint. The Bear-Cut therefore strengthens customer loyalty.

Stefan Eisenhofer

Stefan A. Eisenhofer Transporte

I am highly impressed by the results and the functionality of the machine. Recutting not only saves money, it is also a highly sustainable measure: the mileage of the tires increases significantly, which means we need to purchase fewer new tires. This conserves resources and reduces the carbon footprint of our transport fleet.

Georg Wittwer

Wittwer Spedition & Logistik GmbH

We are truly impressed with the Bear-Cut. It starts with the quick and easy commissioning, including the professional training, and extends to the outstanding cost-benefit performance of the system.

Patrick Bröckers

spieker products GmbH

When I first got to know Mark and Bear Machines, I couldn’t really imagine what the Bear Cut was all about. After testing it myself for the first time – complete enthusiasm! Over time, Mark has shown me many small improvements, all of which he produced himself. You can see the passion with which the Bear-Machines team works on the product.

Dirk Werner

Verkehrsgesellschaft Kreis Unna (VKU)

We have done the calculations carefully, and even under cautious assumptions, it turns out that the Bear-Cut pays off for us within three years at the latest, most likely even earlier.

Mark Berendsen

Managing Partner

With our Baer-Cut machine, we create efficiency and many advantages for hauliers and fleet managers who have commercial vehicles in use. By continuing to use existing tyres, our customers save money. At the same time, this is sustainable and ensures a better environmental balance.

Calculation of the CO₂ value

The estimated CO₂ savings resulting from re-cutting are broken down as follows:

Assumption:

  • Additional mileage gained from a tire through regrooving: 58,050 km
  • Fuel savings: 1.59 L/100 km for 12 tires = 0.1325 L/100 km per tire
  • Up to 25% additional mileage; in the example, 25% of 232,200 km

Fixed value:

  • 3,24 kg CO₂/l Diesel fuel, including its production
  • Average tire weight: 70 kg
  • Raw material input: 1.21 kg of CO₂ per kg of raw tire material
  • Additional production approach: 9 kg reduction in CO₂ emissions per re-cut.

1.) CO₂ savings due to lower fuel consumption

58.050 km x 0,1325 l/100 km x 3,24 kg CO₂/l = 249,2 kg CO₂

2.) CO₂ savings resulting from the raw materials that are not needed

70 kg x 1,21 kg CO₂/kg x 25% = 21,2 kg CO₂

3.) CO₂ Savings from the Proportionate Reduction in Tire Production

Generalized Additional Modeling Approach¹ = 9 kg CO₂

This results in the estimated CO₂ savings per tire:

249,2 + 21,2 + 9 = 279,4 kg CO₂

Rounded: 280 kg of CO₂ per tire

The fuel savings apply exclusively to the additional distance traveled after regrooving, compared to driving on new tires. Four regrooved tires correspond to a calculated diesel savings of approximately 0.53 liters per 100 km.

¹ The manufacturing component of 9 kg of CO₂ is based on a Bear Machines model. The available documentation does not substantiate this as a direct reduction per truck tire retreaded. The raw material factor of 1.21 kg is derived from the previous calculation basis.
The newer combined factor of 2.3 kg for raw materials and manufacturing is not additionally used in this calculation.

The calculation uses the unrounded quotient 1.59 ÷ 12 for the fuel component. Therefore, the calculated result differs from the published example figure of up to 251 kg of CO₂. Actual savings depend, among other things, on the tires, mileage, load, tire pressure, route, and driving style. The total figure is a model estimate, not a guaranteed saving or a complete life-cycle analysis.
