Do EVs Need Higher Tyre Pressures Than Petrol Cars?

Electric vehicles behave differently from petrol cars in ways that reach right down to the tyres. They’re heavier, they deliver torque instantly, and they roll almost silently — all of which change what the tyres are being asked to do. A common question from new EV owners in Australia is whether the old pressure figures still apply. Here’s what actually matters, and why the answer always comes back to your own placard.

Are EVs really heavier than petrol cars?

Yes. The battery pack in an EV can add several hundred kilograms over an equivalent petrol model. A mid-size electric SUV can easily weigh more than a diesel one of the same footprint. As Servistar (an Australian workshop network) puts it, “some EVs are heavier than comparable petrol cars because of the battery pack,” and “higher vehicle load means each tyre has more work to do.” That extra mass is exactly why carmakers often set higher tyre pressures for EVs — the air inside the tyre has to support more weight, just as it does on a fully loaded family car.

So do EVs need higher tyre pressures?

Frequently they do — but the figure comes from the vehicle, not a rule of thumb. An EV’s tyre placard is calculated for its kerb weight, so if that pressure is higher than a similar petrol car’s, that’s the engineering doing its job. The critical rule: use the pressure specified for your vehicle, not a generic figure borrowed from another EV or a petrol car. You’ll find it on the placard (door jamb, fuel/charge flap or glovebox) and in the owner’s manual — the same place we cover in placard pressure vs sidewall maximum. Never inflate to the sidewall maximum instead; that’s the tyre’s ceiling, not your target.

Do EVs need special high-load tyres?

Many do. Because of the weight, EV placards often call for tyres with a higher load index or an XL (Extra Load / reinforced) construction. Fitting a tyre with too low a load rating is both unsafe and can fail a roadworthy inspection. This is a fitment issue as much as a pressure one — see load index requirements for heavy EVs and whether you actually need EV-specific tyres in Australia. The short version: match or exceed the load index on your placard, and don’t downgrade to save money.

How do EV pressures compare to petrol cars?

The table below shows the general pattern. Exact numbers vary widely by model — always read your own placard.

Why do EV tyres wear out faster — and does pressure help?

Electric motors deliver strong torque straight away, so repeated hard launches ask a lot from the tread. Combine instant torque with extra weight and EV tyres often wear faster than on a petrol car. Correct pressure won’t cancel that out, but running under the placard figure makes it worse — under-inflation adds heat and edge wear on an already hard-working tyre. Keeping pressures exactly right is one of the cheapest ways to protect them. We dig into the causes in why EV tyres wear out faster and what to do about it.

Does higher pressure hurt EV range or ride?

Correct pressure actually helps efficiency: under-inflation raises rolling resistance and quietly eats into your range, exactly as it burns extra fuel in a petrol car — the mechanism is identical, as we explain in tyre pressure and fuel economy. The trade-off is a slightly firmer ride, but you should never drop below the placard figure to soften the ride. And because you can’t hear the tyres as much in a quiet EV cabin, it’s easy to miss a slowly deflating tyre — so build in regular checks, as covered in how often you should check tyre pressures.

Frequently asked questions

Can I just add a few psi because my car is an EV?

No — use your placard figure, which already accounts for the weight. Adding pressure on top of that can over-inflate the tyre, reducing grip and centre-wearing the tread.

Where is the tyre placard on an EV?

Same places as any car: usually the driver’s door jamb, sometimes the charge-port flap or glovebox. It lists the correct cold pressures and the load and speed rating your tyres must meet.

Do all EVs need XL tyres?

Not all, but many heavier ones do. Check the load index on your placard and match or exceed it. Fitting an under-rated tyre is unsafe and can fail an inspection.

Will correct pressure improve my EV’s range?

It helps. Under-inflation increases rolling resistance and reduces range, so keeping tyres at the placard pressure is a free way to protect both range and tyre life.

Figures here are general guides for 2026 and vary by model. Always confirm your correct pressures and load rating on your EV’s placard or owner’s manual. Authority sources: Servistar — do electric cars wear tyres faster? and Michelin Australia — rolling resistance.
