Ertiga alloy wheels from the factory are 15 inch, fitted on the ZXi and ZXi+, wrapped in 185/65 R15 rubber, exactly like the steel wheels on the LXi and VXi. The ZXi+ gets a machined two tone finish; the ZXi alloy has its own, simpler look.
Most owners who ask us about alloys drive a lower variant and want the top model look, or want a bigger 16 inch wheel. Both are possible, but an MPV that carries seven people needs the right wheel strength and fitment, not just the right look.

Factory wheels on each Ertiga variant
| Variant | Wheel | Tyre |
|---|---|---|
| LXi | 15 inch steel with cover | 185/65 R15 |
| VXi, VXi CNG | 15 inch steel with cover | 185/65 R15 |
| ZXi, ZXi CNG | 15 inch alloy | 185/65 R15 |
| ZXi+ | 15 inch alloy, machined two tone | 185/65 R15 |
Because the rim size is the same, a factory alloy set from a ZXi or ZXi+ bolts straight onto an LXi or VXi of the same generation, and you keep your existing tyres. This is the safest upgrade, since the maker designed those wheels for the Ertiga's weight.
Before buying aftermarket Ertiga alloy wheels
An aftermarket wheel must match the car on five points:
- PCD: the bolt circle and stud count. Read it off your current wheel or ask the wheel seller to test fit. Our PCD calculator explains how to measure it.
- Centre bore: the middle hole has to hug the hub snugly; if it is larger, fit a correctly sized spigot ring.
- Offset: push the wheel outward and a loaded Ertiga may scuff its arches; pull it inward and the tyre may meet suspension parts.
- Load rating: seven occupants plus bags is serious weight, so get the per wheel rating in writing.
- Overall diameter: the new combination should stand no more than 3 percent off the stock 621 mm height.
No PCD or offset number appears on this page, since the maker's own figure was not available to us. Check your wheel before buying.
15 inch or 16 inch alloys on the Ertiga
A 15 inch alloy keeps the factory tyre, the soft ride and the low replacement cost of a common size. Going up an inch with a 195/55 R16 tyre leaves height almost unchanged at about 620 mm while the wheel looks less lost in the arch. The trade off is a thinner sidewall, a firmer ride over broken roads, and a higher chance of denting the rim in a deep crater when the car is heavy. Wider 205 section tyres also add steering effort in parking. Insurance and warranty claims may ask about non factory wheels, so keep the bill. Separate guides cover 15 inch alloy wheels as well as the 16 inch alloy wheels option.
Caring for machined two tone alloys
The ZXi+ wheel has a bright cut face with a clear lacquer coat over it. Chip that lacquer and moisture creeps beneath it, leaving milky blotches across the bright metal within a single rainy season. Every week or two, rinse off brake dust using a gentle wash solution and a soft bristle brush. Avoid acid wheel cleaners and hard wire brushes. Kerb rash across the bright cut area can be refinished on a lathe at a wheel repair shop, which takes off a thin layer and recoats it. That can only be done a limited number of times. How that lathe refinish works is explained on our page about diamond cut alloy wheels.
Bent or cracked alloy: what to do
A hard pothole hit can bend the inner lip of a 15 inch alloy. The steering may shimmy once you pass 60 km/h, or the tyre may lose air slowly at the bead. Bends in the lip usually respond to a straightening press, but a crack near the spokes or the bolt holes cannot be safely welded for a heavy family car.
Wheel nuts, balancing and alignment
Match nut seats to the wheel you fit; a steel rim nut may not seat properly in an alloy. Snug them diagonally, opposite nut after opposite nut, then recheck torque after a short first drive. Get each wheel balanced when the tyre goes on, and get the alignment checked after any wheel change. These steps keep the steering straight on expressways and stop uneven wear on the front tyres.

Questions owners ask
What size are the Ertiga alloy wheels?
ZXi and ZXi+ alloys measure 15 inch and wear 185/65 R15 tyres. LXi and VXi cars get steel rims of that diameter under plastic covers.
Can I fit ZXi+ alloys on my VXi?
Yes, factory alloys from the same generation bolt on and use the same tyres. Use the correct wheel nuts for alloys.
Will 16 inch alloys fit the Ertiga?
A 16 inch wheel with a 195/55 R16 tyre keeps the overall size close. No factory Ertiga comes with it, so confirm offset, look for contact with the steering fully turned and the car loaded, and expect a firmer ride.
Do alloys improve mileage on the Ertiga?
The change is very small. A lighter wheel helps a little, but a bigger, wider wheel can cancel that out.
Why are my ZXi+ alloys turning white?
Its transparent protective layer has been chipped and moisture has got underneath. A wheel shop can refinish the face; harsh cleaners make it worse.
Can a bent alloy be repaired?
Usually yes if only the lip is bent. A cracked wheel should be replaced, not welded, on a family car.
