Specialist touring tyres, such as Schwalbe's Marathon Plus model, can last for over 10,000km - although these more expensive than the models we put through their paces in our cheap road bike tyres grouptest.
Most road tyres will last between 2,000km and 5,000km, but the good news is that cheaper tyres tend to use harder wearing rubber than speedy summer tyres - so not only do they cost less, they'll likely last you longer too!
