Forget 28mm, much wider tyres are coming
Briefly

Recent lab testing by Cyclingnews suggests that road bike tyres are heading towards larger widths, with 40mm tyres becoming more suitable for average cyclists. Findings show significant benefits from wider tyres in terms of rolling resistance, particularly for those on uneven surfaces like cobbled roads, even though elite time trialists may not advantage from the switch. The tests assessed various Pirelli tyre sizes and demonstrated over an 80-watt reduction in resistance for the wider varieties, indicating a substantial performance improvement for everyday riders.
Cyclingnews found that wider road bike tyres, especially 40mm, could yield significant benefits for most cyclists, particularly on uneven surfaces and cobbled roads.
While time trialists may not gain from it, the data indicates that average cyclists will perform faster with wider tyres, revealing significant advantages like reduced rolling resistance.
