If you ride a scooter or underbone in the Philippines, your scooter tires do a lot of quiet, hard work. They carry you through morning traffic, sudden afternoon downpours, hot concrete at noon, and the occasional pothole that seems to appear overnight. So when it’s time for a replacement, it pays to choose with a little more thought than “whatever the shop has in stock.”
Quick answer: To choose the right scooter or underbone tire in the Philippines, match the exact size printed on your current tire’s sidewall, never go lower on the load index or speed rating, pick tires suitable for wet roads, compare tires by cost per kilometer instead of sticker price, and buy from a reputable seller who can confirm the tire’s specifications, condition, and applicable certifications.
This guide walks you through each of those checks, so you can pick a tire for the way you actually ride.
Start with how you ride
Before looking at any brand, think about a typical week on your bike.
- City commuter: short trips, lots of stop-and-go, and roads that turn slippery the moment it rains. Wet grip and confident braking matter most.
- Delivery or long-distance rider: many kilometers every day, often with cargo or a passenger. Long tread life and a tire that handles heat well matter most.
- Provincial or mixed-road rider: a bit of everything, from highways to rough barangay roads. A sturdy, all-around tread is the safer pick.
Most riders fit one of these, and knowing yours makes every other choice easier.
Read your tire size before you shop
Your correct size is printed on the sidewall of your current tire. You’ll usually also find it on a sticker on the swingarm, under the seat, or in your owner’s manual. Here’s what a typical scooter marking like 90/80-14 M/C 49P TL means:
- 90: the tire’s width in millimeters
- 80: the sidewall height, as a percentage of the width
- – (dash): the construction type. A dash means bias-ply, which is common on scooters and underbones. You may also see B (bias-belted), R (radial), or ZR (radial built for very high speeds) on bigger bikes.
- 14: the rim diameter in inches
- M/C: made for motorcycles
- 49: the load index, which tells you how much weight the tire can safely carry
- P: the speed rating, or the top speed the tire is built for under load
- TL or TT: tubeless or tube-type
When buying, match the size exactly, and never go lower on the load index or speed rating to save a few pesos. A tire carrying more than it was built for can overheat and fail.
If you’re unsure whether your rims can take a tubeless tire, ask a trusted shop before mounting anything.
Other sidewall markings worth knowing
- Date code: the last four digits after “DOT.” The first two are the week, the last two are the year, so “5219” means the 52nd week of 2019.
- E-mark: a circle with the letter E and a number, showing the tire is approved under the international UNECE Regulation 75 standard.
- Rotation arrow: shows which way the tire must turn when mounted. A tire fitted backwards won’t clear water or grip the way it was designed to.
Match the tread to Philippine roads
Our weather is hard on tires, so the tread pattern deserves a closer look.
- Rainy season riding: look for deeper grooves that push water out from under the tire. This helps the tire keep contact with the road instead of skimming over puddles.
- Hot, dry city roads: a tread with more rubber touching the road gives steady grip and stability.
- Rough or unpaved roads: go for sturdier tread blocks and stronger sidewalls that can handle bumps and loose surfaces.
It also helps to know how rubber compounds behave. Softer rubber grips better but wears faster, especially on hot asphalt. Harder rubber lasts longer but can feel less sure-footed on wet painted lines and oily patches. Some tires combine both, with a harder center for mileage and softer edges for cornering.
Compare cost per kilometer, too
The cheapest tire on the rack isn’t always the cheapest tire to own. A quick way to compare is to work out what each one costs for every kilometer you ride:
Cost per km = tire price ÷ expected kilometers of use
For example, using sample numbers only:
- Tire A costs ₱1,500 and lasts 12,000 km, so it works out to about ₱0.13 per km.
- Tire B costs ₱900 and lasts 6,000 km, so it works out to ₱0.15 per km.
In this example, the pricier tire is actually the better deal. Real tread life depends on your riding style, load, tire pressure, and road conditions, so ask the shop about expected mileage. A simple habit that helps: write your odometer reading on the receipt when you buy, so you’ll know exactly how long each tire lasted.
Buy smart and check before you pay
- Buy from trusted sources: authorized dealers, official brand stores, or official flagship stores on online marketplaces.
- Check the date code: make sure it’s recent. Fresher is better.
- Check applicable certification: Philippine PS or ICC marking requirements apply to products covered by DTI’s mandatory certification rules. Do not assume every scooter or motorcycle tire must carry these marks. Check current DTI requirements for the product category and ask a reputable seller for product documentation when needed. See the DTI Bureau of Philippine Standards explanation.
- Inspect the tire: walk away from tires with cracks, flat spots, bulges, or a price far below what other sellers charge.
Keep your new tires in good shape
- Check pressure regularly while the tires are cold, using the recommended pressure on your bike’s sticker or in the manual.
- Watch the wear indicators. These are small raised bumps inside the grooves, marked “TWI” or with a small arrow on the sidewall. Once the tread is level with them, it’s time to replace the tire.
- Take it easy at first. New tires need a short break-in period, so ride gently for the first hundred or so kilometers.
- Leave mounting to the pros. A qualified mechanic will seat and balance the tire properly.
Frequently asked questions
Is tubeless better for daily commuting?
For many commuters, yes, as long as your rims are tubeless-compatible. A puncture in a tubeless tire usually leaks slowly, which gives you time to reach a shop, and small punctures can often be plugged. Tube-type tires still make sense for bikes with spoked wheels.
Should I replace both tires at the same time?
Not always. The rear tire usually wears faster, so it’s normal to replace each one when it reaches its wear indicator. If you switch to a different brand or tread type, though, many riders prefer to change both for more predictable handling.
How old is too old for a tire?
There is no single legal expiration date for every motorcycle tire. Its condition depends on storage, use, exposure and visible damage. For example, Michelin advises professional annual inspections after five years of use and replacement by ten years from the manufacturing date; that is manufacturer guidance, not a universal legal rule. Check the instructions for your tire brand and have any cracked, damaged or unusually worn tire assessed sooner. A manufacturer’s warranty period is separate from a tire’s safe service life.
Understand your motorcycle tire warranty before buying
A warranty covers specified defects under its terms; it does not guarantee a tire’s safe lifespan. Coverage can start from the purchase date or manufacturing date, and Philippine terms may differ from international policies. Read our brand-specific warranty guides and confirm current conditions with the official seller.

The bottom line
The right tire starts with how you ride. Get your size right, pick a tread that suits our roads and weather, compare cost per kilometer, and buy from a source you trust. Your tires are the only part of your bike that touches the road, so a few extra minutes of checking go a long way.
Safety note: Always follow your motorcycle and tire manufacturer’s instructions, and have tires mounted by a qualified mechanic. If you notice damage, bulges, or unusual handling, stop riding and have the tire checked.
