What effect can inflation pressure below the manufacturer’s recommendation produce?

Correct answer

More deformation and wear at the tread edges.

It can increase tyre deformation, heating and wear, especially at the tread shoulders. This is not because air fills a tube unevenly: many tyres are tubeless. Check pressure when cold and adjust it for load according to the manufacturer.
