Short answer: sometimes, but only within tight limits

If you need to replace one tyre range rover awd owners should first measure tread depths: if the new tyre’s rolling diameter sits within roughly 2–3mm tread depth of the other three, a single replacement is acceptable; outside that, you risk differential and transfer case stress.

Permanent AWD Range Rover models, including full-size Range Rover and Sport, are most sensitive to mismatches; Velar and Evoque with on-demand AWD are slightly more forgiving, yet the 3mm rule remains the practical safety line.

Why rolling diameter matters for AWD drivetrains

Different rolling diameters cause the worn tyre to spin faster under load, which drags the centre differential and transfer case; that extra rotational speed and heat can accelerate wear or lead to failure, with repairs running into four-figure sums on many Range Rover models.

Even a 2–3mm tread-depth mismatch changes effective circumference enough to create drivetrain slip; that slip is what triggers uneven wear and potential long-term damage in permanent AWD systems used on models such as Discovery and Defender.

How to measure tread correctly before replacing one tyre

Use a metric tread depth gauge and measure at the centre groove of each tyre while the tyres are cold; record centre depth for all four tyres and compare the new tyre’s depth to the most-worn tyre, not the average.

If the difference is more than about 3mm between the new tyre and the most-worn tyre, plan to fit at least a pair on the same axle or consider having the new tyre shaved to match; many tyre specialists will shave premium tyres to achieve a closer rolling radius.

Replacement strategies: single, pair, or a full set

Practical rule of thumb for replace one tyre range rover awd decisions: (1) all four tyres within ~3mm = single tyre OK; (2) set is early life and one tyre damaged = fit a single (if within tolerance); (3) set is mid-life and one tyre damaged = replace the pair on the same axle and rotate so the more-worn pair runs on the front; (4) all four worn = full set replacement.

On many JLR AWD models the cheapest long-term option is fitting a pair on the same axle rather than risking differential or transfer case repairs, because a gearbox or transfer-case rebuild typically costs far more than two tyres plus labour.

Electronics: air suspension, ADAS and TPMS can complain

A small rolling-radius mismatch can show up as ride-height drift in electronic air suspension, ADAS wheel-speed sensor discrepancies and TPMS relearn requirements; these systems use wheel-speed and radius as inputs, so expect fault codes if mismatch grows.

If fault codes appear after a tyre change have the car scanned for ABS/ESC and height-sensor codes; if you need a full diagnostic we can scan and interpret the codes to confirm whether rolling-radius drift is the root cause.

What to do immediately after a tyre failure on the road

If you get a puncture, measure and record the remaining centre tread depths of the other three tyres as soon as you can; if the most-worn remaining tyre is within 2–3mm of a new tyre you can replace singly, otherwise arrange a same-axle pair replacement.

Avoid temporary run-flat repairs that leave a mismatched diameter long-term; if a replacement tyre is fitted, ask the fitter to note the exact tread depth in mm and schedule a front-to-rear rotation at the next service to keep wear even.

Preventing premature single replacements

Rotate tyres front-to-rear at each service interval to even wear so a single replacement remains an option longer; uneven wear makes single replacements rare once a set reaches mid-life.

Keep tyre pressures correct and check monthly because under-inflation increases sidewall vulnerability to potholes and curb damage; correct pressures also help maintain even centre tread wear across the set.

When to call a specialist

Call a specialist if your single-tyre change triggers persistent ABS/ESC, ADAS or air-suspension codes, or if you cannot match a new tyre within about 3mm of the most-worn tyre; those symptoms point to rolling-radius drift that needs a diagnostic scan.

Single vs Pair vs Full Set: When to Use Each

Final Thoughts

A single tyre replacement on a Range Rover AWD is possible, but only when the new tyre sits very close to the other three in centre tread depth, typically within about 2–3mm. Measure, compare and, when unsure, choose a pair on the same axle or a full set to protect the centre differential and transfer case. Small preventive steps like monthly pressure checks and regular rotations make single replacements viable for longer and save you from expensive repairs.
