Quick check: will bigger tyres get you a JPJ summons?

You finally swapped out your stock tyres. Wider. Taller. Looks way better.Then you spot a JPJ roadblock ahead and suddenly your brain goes:

“Eh… can JPJ saman me for this ah?”

Good question. And you’re not alone — tyre size changes are one of the most misunderstood mods in Malaysia.

Let’s clear it up properly.

Is It Actually Illegal to Change Your Tyre Size?

No — changing tyre size is not illegal by default.

But here’s the catch:JPJ only allows tyre changes within certain limits. Go beyond that, and you’re officially in “summons territory”.

JPJ treats tyres as a safety-related component, not just aesthetics.

Why Tyres Matter to JPJ

Tyres directly affect:

• Speedometer accuracy

• Braking performance

• Vehicle stability

• Fender and suspension clearance

That’s why JPJ treats tyre size changes as a technical modification, not a cosmetic one.

1. Your Tyres Are Way Bigger Than Stock

JPJ generally allows a maximum ±3% difference in overall tyre diameter from your original (OEM) tyre size.

Go beyond that, and:

• Your speedometer becomes inaccurate

• Braking and handling can be affected

• JPJ can classify it as a non-compliant modification

This is common with:

• Myvi owners upsizing aggressively

• Older Protons running oversized rims

• SUVs with “stance-style” setups

• ---

2. Tyres Stick Out of the Fender

If your tyres:

• Protrude outside the wheel arch

• Look obviously wider than stock

• Use spacers to clear suspension

• That’s an easy visual trigger for JPJ officers.

  If it sticks out — it sticks out to JPJ too.

3. Your Mod Affects Safety or Steering

JPJ may issue a summons (or inspection order) if:

• Tyres rub against the body

• Steering lock is restricted

• Suspension geometry is affected

• These usually show up during:

  • Roadblocks

  • Accident inspections

  • Puspakom checks

  • ---

4. You Fail a JPJ or Puspakom Inspection

Even if you “got away with it” for years, tyre size issues often surface when:

• Selling your car

• Transferring ownership

• Renewing insurance

• Going for inspection

When You SHOULD Report It

You should inform JPJ if:

• You upsized significantly

• You changed rim size beyond factory options

• Fender rolling, spacers, or suspension mods were involved

Not reporting doesn’t just risk a summons — it can also:

• Void insurance claims

• Reduce resale value

• Cause inspection failures later

• That’s when people panic.

How to Make Your Tyre Size “JPJ-Safe”

If you want peace of mind, do this:

1. Check your original tyre specs

2. Confirm your new size stays within tolerance

3. If unsure, go for Puspakom inspection

4. Submit the details to JPJ if required

Yes, it’s a bit leceh — but way better than fixing it last minute.

Expert Quick FAQs

1. Can JPJ saman me just for bigger tyres?

Yes, if the size exceeds limits or affects safety.

2. Are rim changes also regulated?

Yes. Rim size + tyre size are evaluated together.

3. Will insurance still cover me?

Not guaranteed. Illegal mods can void claims.

4. Do JPJ officers actually check tyre size?

Yes — especially during Ops Bersepadu or obvious mods.
