When to replace motorcycle tires: tread, DOT age, pressure
Tread depth alone does not tell the whole story - a tire can look fine and still be past its safe age. Garagely tracks both, front and rear, and gives you a straight verdict.
Garagely tracks each tire, front and rear, by brand, install date and odometer, current and new tread, cold and hot pressure, DOT code, size and compound. From those it calculates percent worn, percent life left, kilometers to the legal tread limit, age, and a Good, Worn or Replace verdict, with an age warning around the five-year mark even when tread looks fine.
What riding on the wrong tire actually risks
- Tread below the legal minimum loses grip fast, and it is the one thing most riders only check by eye, if at all.
- A tire can look fine on tread and still be years past a safe age - the rubber hardens and grip drops well before it looks worn.
- Wrong pressure, hot or cold, changes handling and wears the tire unevenly, shortening the life of a tire you already paid for.
- Finding out a tire is past its limit right before a ride leaves no time to actually replace it before you need the bike.
Myth vs reality
The myth
If the tread still looks deep, the tire is fine.
Why people believe it
Tread depth is the one thing riders are told to check, and a tire with plenty of tread left does look roadworthy at a glance.
The reality
Rubber ages on the calendar, not just on the tread gauge. A tire well past the DOT age warning can have hardened compound and reduced grip even with tread to spare.
What to do instead
Log the DOT code and let Garagely track age alongside tread. The Good, Worn or Replace verdict accounts for both, so a hidden age problem does not get missed.
Riders like you
Tread looked nearly new, but the DOT code on the sidewall told a different story once actually checked.
Logged the DOT code and got an age warning well before the tread gauge would have flagged anything, and replaced the tire before a trip instead of during one.
Runs hot and cold pressure differently for track and street and used to reset the gauge from memory each time.
Logs both pressures against the tire entry, so the right number for the day is always one look away instead of a guess.
Wears through rear tires fast and kept losing track of exactly when the current one went on.
Sees percent life left and kilometers to the legal limit update automatically, so a tire change is planned around a number, not a surprise squeal in a corner.
Tracking a tire, step by step
- 1
Log the tire front and rear separately
Brand, type, size, compound, install date and odometer for each tire on the bike.
- 2
Enter tread
"Current tread (mm)" and "New tread (mm)" set the baseline the wear percentage is calculated against.
- 3
Enter pressure
"Cold pressure" and "Hot pressure" are tracked separately, so the right number is on hand whatever the tire's temperature.
- 4
Enter the DOT date code
"DOT date code / age" drives the age warning, independent of how much tread is left.
- 5
Read the verdict
Percent worn, percent life left, kilometers to the legal minimum tread, age, and a clear "Good", "Worn" or "Replace" status.
- 6
Use fitment when you shop for a replacement
"Use this size" pulls the correct size straight from your bike's fitment data, so the wrong size never makes it to checkout.
- 7
Log the change and the old tire retires
Recording a tire change closes out the old tire's entry automatically and starts tracking the new one from zero.

Questions riders ask
Does Garagely track tire age, not just tread depth?
Yes. The DOT date code is logged alongside tread, and the age warning triggers around the five-year mark even if the tread still looks fine.
Can I track different cold and hot pressures for the same tire?
Yes, cold and hot pressure are separate fields on the same tire entry, so both numbers are on hand whenever you need them.
What happens when I log a tire change?
The old tire's entry closes out automatically and the new tire starts tracking from zero, with its own install date and odometer.
How does fitment help me buy the right replacement?
"Use this size" pulls the correct size straight from your bike's fitment data, so you are never guessing at a size code while shopping.
Is tire tracking free?
No, tire tracking is a Pro feature. It covers both tires on every bike in your Pro account.
