Continental has welcomed a significant amendment to Spain’s General Vehicle Regulations, describing the move as an important step towards greater road safety and regulatory alignment with the rest of Europe.
Spain’s Revised Tyre Regulations
Published in Spain’s Official State Gazette (BOE) and effective from 30 May 2026, the revised regulation introduces a minimum tread depth requirement of 1mm in the main grooves of tyres fitted to heavy commercial vehicles, including trucks, buses and trailers.
While a 1.6mm minimum tread depth has long applied to passenger cars and light commercial vehicles in Spain, the legislation previously contained no specific numerical requirement for heavy vehicles. Instead, tyres simply had to display visible tread, leaving room for differing interpretations during roadside inspections and enforcement checks.
According to Continental, the absence of a clearly defined legal threshold had been a longstanding issue for both transport operators and tyre manufacturers, creating uncertainty for fleets and enforcement authorities alike. The company noted that the new rule brings Spain into line with practices already established in many other European countries.
“This amendment is highly significant and something the industry has been waiting for for many years,” said Antonio Sangüesa, Head of Fleet Solutions, Services and Fleet Digitalisation at Continental Spain. “It never made sense for light vehicles to have a clearly defined minimum tread depth while heavy commercial vehicles operated under a legal grey area. The lack of a specific requirement often led to disputes and inconsistent interpretations.”
Continental believes the measure will have a direct positive impact on road safety without imposing a significant additional burden on professional fleet operators. The company argues that most transport businesses already monitor tyre condition closely and typically replace tyres before they reach minimum legal limits.
“From our perspective, this is a very positive development because it directly improves road safety,” Sangüesa added. “Most professional fleets already manage their tyres responsibly, so the regulation is unlikely to create additional costs. However, it provides enforcement authorities with a clear and objective standard and helps remove unsafe vehicles from the road.”
Under the new rules, operators found to be using tyres with tread below the 1mm minimum tread depth can face fines of €200 per defective tyre. In more serious cases, such as vehicles operating in adverse weather conditions with multiple tyres deemed unsafe, drivers could face higher penalties and licence-point deductions under Spain’s road traffic legislation.
The regulatory update also introduces other changes affecting the commercial vehicle sector. Among them is a requirement for vehicles above 3.5 tonnes to use tyres carrying recognised severe winter service markings (such as the 3PMSF symbol) on steering and drive axles when winter equipment requirements apply. The reform also advances the digitalisation of vehicle inspection documentation through the wider adoption of electronic ITV (roadworthiness test) records.
For the Spanish road transport industry, the changes mark the end of a long-standing regulatory anomaly and represent a broader effort to modernise vehicle standards, harmonise technical requirements with European practice and improve road safety across the commercial vehicle sector, Continental states.
