Bus and Coach Fleet Tyre Processing: Recycling Commercial Tyres

By:     Kieran Donnelly

Expert review by:     Conor Murphy

Bus and coach operators run some of the most tyre-intensive fleets on UK roads. A single-deck bus operating urban routes may need tyre replacement every 30,000 to 50,000 miles. A fleet of 50 buses turning over tyres at this rate generates several hundred end-of-life tyres per year, all of which need to be collected, stored, and disposed of under the waste duty of care requirements that apply to any commercial waste producer.

The tyres themselves are a distinctive category. Coach and bus tyres are large, heavy, and reinforced to handle the continuous load cycles of passenger service. Standard car tyre processing equipment is not appropriate. The right equipment for a bus depot is either a dedicated truck tyre baler or a combination of sidewall cutter and truck tyre baler that processes the tyres efficiently and produces bales suitable for recycling.

Tyre Types and Dimensions for Bus and Coach Fleets

Standard single and double-deck urban buses typically run on R22.5 tyres in sizes 275/70, 295/80, or 315/80. Coach tyres are similar in fitment size though often in different tread pattern specifications for motorway rather than urban use. These are truck-category tyres for the purposes of processing equipment selection, not car or van category.

The key difference from a processing perspective is the significantly higher steel content and construction weight of bus and coach tyres compared to car tyres. A 295/80 R22.5 bus tyre typically weighs 55 to 65kg compared to 8 to 12kg for a car tyre. The steel bead and belt construction is more robust and requires more force to compress or cut than a passenger car equivalent.

Sidewall Cutting Before Baling: Why It Matters for Bus Tyres

Bus and coach tyres benefit significantly from sidewall cutting before baling. The stiff sidewall construction of R22.5 tyres resists compression, and whole tyres baled without pre-cutting produce lower-density bales that take more space during storage and transport. Cutting the sidewalls removes the structural resistance, allowing the remaining carcass to compress to a much higher density.

The practical result is more tyres per bale, fewer collections needed, and better economics at every stage from storage through to disposal. A bale of whole bus tyres typically contains 8 to 12 tyres. A bale of sidewall-cut bus tyres from the same compression force contains 20 to 30 tyre carcasses. The difference in storage efficiency is significant for a depot with limited space.

The Gradeall Truck Tyre Sidewall Cutter is designed for R22.5 commercial vehicle tyres including bus and coach formats, removing both sidewalls cleanly and quickly before the carcass is transferred to the baler.

Fleet Size and Equipment Throughput Planning

A fleet of 50 buses with an average tyre life of 40,000 miles, each vehicle covering 50,000 miles per year, generates approximately 400 tyres per year from that fleet alone. That’s around 8 tyres per week or one to two per working day. A single truck tyre baler operating on a standard shift can process this volume comfortably as part of normal workshop operations.

Larger fleets, particularly municipal bus operators with 200 to 500 vehicles, generate several thousand tyres per year. For these operations, a dedicated processing line with sidewall cutter feeding a truck baler, operated by a designated staff member, is justified both on volume and on operational efficiency grounds.

Private hire coach operators tend to generate fewer tyres at lower volume because coaches cover lower annual mileages than urban buses, but their tyres are the same category and require the same processing equipment.

Storage Compliance and Permit Thresholds

Bus depots storing end-of-life tyres face the same environmental permitting thresholds as any other commercial site. Storing more than 1,000 tyres in the open air or more than 5,000 indoors requires an environmental permit under the Environmental Permitting Regulations. The T8 waste management exemption covers storage below these thresholds when registered with the Environment Agency or SEPA.

Baling tyres as they arise from the workshop is the most effective compliance strategy. A depot baling tyres on arrival and maintaining regular bale collections does not need to manage accumulating loose tyre stockpiles and typically remains within exemption thresholds regardless of fleet size.

“Bus and coach tyres are one of the most consistent and predictable waste streams we see,” says Conor Murphy, Director of Gradeall International. “The fleet is a known size, the mileage is known, the tyre replacement schedule is planned. That makes it straightforward to specify equipment correctly and get predictable results.”

Tyre Recycling Routes for Bus and Coach Tyres

Whole bus tyres and cut bus tyre carcasses go primarily to tyre recycling facilities where they are processed into crumb rubber via shredding and granulation. The crumb rubber goes to sports surface manufacturers, playground equipment installers, and construction aggregate blending operations. Some whole or cut tyres go to energy recovery at cement kilns where the high calorific value and rubber mass of commercial vehicle tyres makes them valuable TDF (Tyre Derived Fuel) feedstock.

Baled formats are preferred by most recycling facilities because they are easier to handle and transport than loose tyres. The bale wire is removed at the receiving facility before processing.
