WHO THIS IS FOR
IS THIS YOU?
Riders wondering whether their tyres need replacing
You are not sure how to judge tyre wear and want clear guidance on when a tyre is past its useful life versus when it still has kilometres left.
Cyclists trying to balance tyre cost with safety
Quality tyres are expensive and you want to maximise their lifespan without compromising grip and puncture protection.
THE ROADMAN VIEW
The Roadman view
Tyres are the most important contact point between you and the road, and yet most riders run them until they are absolutely bald before considering a replacement. Anthony has seen riders show up to group rides on tyres with visible threads showing through the rubber, and that is a real safety concern — especially in the wet. A worn tyre does not just puncture more often, it grips less in corners, and that is where the real risk sits.
The practical advice is clear: inspect your tyres every month, run your thumb across the tread to check for flat spots, and look at the sidewalls for cracking. If the rear tyre has a noticeably flat centre profile instead of the rounded shape it had when new, it is time to replace it. And always replace the front tyre before the rear if you can only afford one at a time — a front tyre blowout or loss of grip is far more dangerous than a rear one.
EXPERT EVIDENCE
WHAT THE EXPERTS SAY
- Josh PoertnerFormer Zipp technical director, tyre and aerodynamics engineer
Tyre compound degrades with UV exposure and ozone even when not being ridden. A tyre that has been sitting unused for two years has significantly reduced grip and increased cracking risk, regardless of tread depth. I recommend replacing tyres after 18-24 months even if they look fine, because rubber compound degradation is invisible until failure.
PRACTICAL APPLICATION
DO THIS WEEK
Inspect tyres monthly using the thumb test
Run your thumb firmly across the centre tread of each tyre. A new tyre feels rounded; a worn tyre feels flat across the centre. If the centre is noticeably flat over a width of 10-15mm, the tyre has lost significant rubber and should be replaced soon. Check sidewalls for cracks, cuts, or fraying.
Rotate or replace rear tyres at roughly twice the rate of fronts
Rear tyres carry 55-60% of rider weight and wear roughly twice as fast. Some riders rotate front to rear at the halfway point (e.g., move the front to the rear at 3,000 km and fit a new front). This equalises wear but means both tyres are partly worn simultaneously.
Check tyre pressure before every ride
Under-inflation increases rolling resistance and accelerates sidewall wear. Over-inflation reduces contact patch and grip. Use a floor pump with a gauge and check manufacturer recommendations for your tyre width and rider weight.
COMMON MISTAKES
WHAT CYCLISTS GET WRONG
MISTAKERunning tyres until a catastrophic puncture or blowout forces replacement.
FIXReplace proactively based on visual wear rather than waiting for failure. A blowout at 50 km/h on a descent is not worth the extra 500 km of tyre life.
MISTAKEBuying the cheapest tyres available to save money.
FIXQuality tyres from established manufacturers (Continental, Vittoria, Pirelli, Michelin) use better compounds that grip more consistently, puncture less often, and often last longer than budget alternatives. The cost per kilometre of a premium tyre is often lower.
MISTAKEStoring bikes with tyres exposed to direct sunlight for months.
FIXUV degrades rubber compounds. Store bikes out of direct sunlight or cover the wheels. If your bike sits unused over winter, inflate tyres to 60% of max pressure and rotate them monthly to prevent flat spots.
