Two tyres of the same size sit side by side at a shop. One costs far less than the other, and nothing on the price tag explains why.
Five things decide whether a price is worth paying: how much tread is left, how old the tyre is, whether it suits your car, how well it grips in the wet, and what protection comes with it. A tyre’s value is the safe, usable life you get for what you pay, which is not the same as the lowest price today. The legal tread limit and manufacturer age guidance both mean a very cheap tyre can have far less life left than it first appears, which is worth knowing before shopping for cheap tyres.

How Much Tread Is Left?
Tread depth sets how much usable life a tyre has left. A new tyre starts at roughly 7 to 9mm, according to Bridgestone Singapore’s published guidance, and the Land Transport Authority (LTA) sets the legal minimum at 1.6mm. The usable tread is the difference between the two, so a tyre close to that limit offers far less life than its price might suggest.
The arithmetic is simple. Taking 8mm as a typical new tyre, usable tread is 6.4mm. A tyre with 4mm left has just 2.4mm before it reaches the legal limit, which is a little over a third of the usable life.
That gap explains many price differences. A cheaper tyre with less tread isn’t a bad tyre, but the buyer gets fewer kilometres for the money, and the savings shrink the sooner it needs replacing.
How Old Is the Tyre?
Age affects value even when the tread looks fine. Rubber degrades over time, so Michelin recommends an annual professional inspection once a tyre passes five years of use, and replacement ten years after manufacture. The date sits in the last four digits of the DOT code on the sidewall: two digits for the week, two for the year.
Michelin’s own example is a code ending in 3520, which means the 35th week of 2020. A tyre ages from the day it’s made, not the day it’s fitted, so an unused tyre that has sat in storage for years still counts. That’s one reason two tyres with the same tread can carry different prices.
Age alone doesn’t make a tyre unusable, since tread wear and overall condition matter too. The date code is a starting point rather than a verdict.
Does It Match Your Car, and How Does It Grip in the Wet?
The tyre needs to match the size, load index and speed rating that the car’s manufacturer recommends. Michelin notes that these details are moulded into the sidewall. A cheap tyre that doesn’t match the specification is poor value at any price.
Two tyres of the same size can behave differently on a wet road, because makers design rubber compounds and tread patterns differently. In a country with frequent heavy rain, that difference matters in everyday driving, not only on a test track.
What Comes With the Tyre?
Value also includes what happens after the sale. A warranty can cover faults that weren’t obvious at fitting, but terms vary, and careful fitting affects how a tyre performs from the first drive. Ask what the warranty covers, for how long, and whether fitting is included in the quoted price.
Some retailers state warranty periods upfront. Mrrjestic Tyres, for example, sets out its new and used tyre range online, including new tyres from brands such as Michelin, Dunlop and Bridgestone, and used tyres that come with a 6-month warranty. Whichever shop you use, comparing quotes for exactly the same size is the fairest way to see what a price gap actually buys.
A Quick Checklist for Comparing Tyres
| What to check | Why it affects value |
| Tread depth left | Sets how many kilometres remain before the 1.6mm legal minimum |
| DOT date code | Shows age; Michelin advises inspection after five years and replacement by ten |
| Size, load index and speed rating | Must match what the car’s manufacturer recommends |
| Warranty terms | Shows what is covered, and for how long |
| Fitting | Affects how the tyre performs from the first drive |
Is a Cheaper Tyre Ever the Right Choice?
Yes. A cheaper tyre with plenty of tread, a recent date code, the right specification and a warranty can be good value. The problem starts only when a low price hides low tread, old rubber or the wrong specification.
The fairer comparison is cost per kilometre of usable life, not the number on the tag. A tyre that costs 50 per cent more but lasts twice as long is the cheaper choice per kilometre. One that costs half as much but lasts a third as long is not a bargain.
