A wheel loader tyre size is the code moulded onto the sidewall, such as 17.5-25 or 23.5R25, that states the tyre’s width, its construction, and the rim it fits. On a wheel loader (the machine most Indian sites call a payloader), that code decides how much weight the machine can carry, how well it grips, and how long the tyre lasts. Tyres are the second biggest running cost on this machine after diesel, so reading the code correctly is worth a few minutes.
This guide explains what each part of the code means, lists the sizes fitted to the machines listed on DesiMachines, and shows how to match a tyre to the ground you actually work on.
How do you read a wheel loader tyre size?
Take 23.5R25, one of the commonest sizes in India. The 23.5 is the section width of the tyre in inches, measured across the widest part of the sidewall. The 25 is the rim diameter in inches, so that tyre only fits a 25-inch wheel. The letter in the middle tells you how the tyre is built.
An R means radial construction. A dash, as in 23.5-25, means bias (also called cross-ply) construction. Some listings write it as 23.5 x 25, which means the same thing as the dash. Compact machines sometimes use a metric-style code instead, such as the 16/70-20 fitted to the ACE ALN 100, where 16 is the width in inches and 70 is the aspect ratio.
You will often see extra markings after the size. L3 or L5 is the tread pattern class. 20PR is the ply rating, a measure of carcass strength. On the Hindustan 2021E the full code reads 14.00 x 25-20 PR E3/L3, which packs size, ply rating and tread class into one line.
What tyre size does each wheel loader class use?
Tyre size tracks machine weight closely. A heavier machine with a bigger bucket needs a wider tyre on a larger rim to spread that load. The pattern below comes from the specifications published for the machines listed on DesiMachines in August 2026.
| Machine | Operating weight | Bucket capacity | Tyre size |
|---|---|---|---|
| ACE ALN 100 | 4,000 kg (4 tonnes) | 1.0 m³ | 16/70 – 20 (PR14) |
| ACE ALN 300 | 9,970 kg (9.97 tonnes) | 1.7 m³ | 17.5 x 25-20 PR |
| Hyundai HL930I | 10,600 kg (10.6 tonnes) | 1.7 – 3.0 m³ | 17.5-25 L-3 12PR TT |
| Hindustan 2021E | 11,637 kg (11.64 tonnes) | 1.53 – 3.0 m³ | 14.00 x 25-20 PR E3/L3 |
| Hyundai HL950I | 17,700 kg (17.7 tonnes) | 3.0 m³ | 23.5-25 L-3 16PR TT |
| CAT 950GC | 18,849 kg (18.85 tonnes) | 2.9 – 4.4 m³ | 23.5R25 |
| Volvo L180H | 27,000 – 28,400 kg | 3.7 – 16 m³ | 26.5 R25 L3 |
| Cat 972L | 24,897 kg (24.9 tonnes) | 3.4 – 9.9 m³ | 26.5R25 L3 |

Three sizes cover most Indian work. Compact machines under about 10 tonnes run 16/70-20 or 17.5-25. The high-volume 17 to 19 tonne class, which does the bulk of quarry, block-yard and road work, runs 23.5-25. Machines above roughly 23 tonnes move up to 26.5-25 and then 29.5-25. If you are still choosing a machine size, wheel loader types by size class works through what each class is good for.
What do L2, L3, L4 and L5 mean?
The L code is the tread class, and it describes how deep the tread blocks are and what job the tyre is built for. It is set by an international standard, so an L3 from one brand is broadly comparable to an L3 from another.
| Class | Tread depth | Built for | Typical Indian use |
|---|---|---|---|
| L2 | Shallow | Soft ground, sand, snow | Rare; loose sand and farm-type work |
| L3 | Standard | General traction on mixed ground | The default fitment on most machines |
| L4 | About 1.5 times L3 | Abrasive surfaces, longer wear | Quarries, aggregate yards, heavy site work |
| L5 | About 2.5 times L3 | Sharp rock, maximum cut resistance | Mining faces and hard rock loading |
Most machines leave the factory on L3, which is a sensible middle setting. Moving up to L4 or L5 buys you rubber depth and cut resistance, and costs you money and heat: a thicker tyre runs hotter, so it suits slow work over short distances rather than long carry cycles on a hard haul road.
An E code sometimes appears instead of or alongside L, as on the Hindustan 2021E’s E3/L3 marking. E is the earthmover class used for dump trucks and similar haulers, and its appearance simply means the tyre is rated for both duties.
Bias or radial: which suits Indian sites?
Bias tyres are built with the cord layers running diagonally across the tyre, which makes a stiff sidewall. Radial tyres have the cords running straight across from bead to bead with a steel belt under the tread, which makes a flexible sidewall and a footprint that stays flat on the ground.
In practice, the difference plays out like this. Bias tyres resist sidewall cuts better and cost less to buy, so they hold their place on rough, rocky sites and on machines that work slowly in one spot. Radial tyres run cooler, wear more evenly and burn less fuel over long carry cycles, so they earn their price on machines that move material any real distance.
Look at the table above and you can see manufacturers making exactly that choice. The Hyundai HL950I lists a bias 23.5-25, while the similarly sized CAT 950GC lists a radial 23.5R25. Same class of machine, two different answers, both defensible.
One practical warning: never mix bias and radial on the same axle. The two carcass types flex differently under load, which puts the drivetrain in a permanent fight with itself and wears both tyres unevenly.
What does the ply rating (PR) mean?
Ply rating is a strength grade, written as 12PR, 16PR, 20PR and so on. It began as a literal count of the fabric layers in the tyre, but modern materials are far stronger than the old cotton plies, so today it is only a comparison scale. A 20PR tyre carries more load than a 16PR tyre of the same size; it does not contain twenty of anything. The same scale is used on pick and carry cranes, where ply rating climbs in step with tyre size right across the class, as set out in the guide to hydra crane tyre sizes by tonnage class.
The rating matters because it sets the safe load and the correct inflation pressure. Fitting a lower ply rating than the machine specifies looks like a saving until the sidewall flexes past its limit under a full bucket and fails. The figure to follow is the one on the machine’s specification, and the sizes above show that even similar-weight machines differ: the ALN 300 lists 20 PR at about 10 tonnes, while the HL930I lists 12PR at 10.6 tonnes, because carcass design differs between makers.
TT in a code such as 23.5-25 L-3 16PR TT means tube type, so the tyre runs with an inner tube. TL would mean tubeless. Fit the tube type the rim is built for and nothing else.
How do you pick the right tyre for your site?
Start with the machine’s specification and treat it as the baseline: size and rim diameter are fixed by the wheel, so those are not open to choice. What you actually choose is tread class, construction and ply rating.
Ask three questions about the work. How sharp is the ground? Broken rock and demolition rubble push you toward L4 or L5 and toward bias construction. How far does the machine carry each load? Anything beyond a short shuttle favours radials, which run cooler over distance. How many hours will the machine work each month? A machine on hire for long shifts justifies a better tyre; a machine that works a few hours a week does not.
Then check what your local dealer actually stocks. A tyre that is theoretically ideal but three weeks away is worse than a good tyre available tomorrow, because the machine earns nothing while it waits. Tyre availability by size is one of the quieter reasons the 23.5-25 class is so popular in India.

What makes wheel loader tyres wear out early?
Most tyres on Indian sites die before their tread is used up, and the causes are almost always operational rather than mechanical.
| Cause | What it looks like | What to change |
|---|---|---|
| Wrong inflation pressure | Wear down the centre (over) or both shoulders (under) | Check pressures cold, weekly, against the machine specification |
| Spinning the wheels into the heap | Fast, even tread loss on the drive tyres | Enter the heap lower and let the bucket do the work |
| Debris left around the loading face | Cuts and punctures in the sidewall | Clean the working area; it takes minutes |
| Sharp turns under a full bucket | Scrubbed, feathered tread edges | Straighten before lifting; use a wider approach |
| Overloading the bucket | Sidewall bulging, quicker overall wear | Match bucket size to material density |
Bucket choice feeds directly into that last line, because a bucket sized for light material becomes an overload when it is filled with wet aggregate. Our guide to wheel loader bucket types and sizing covers how to match the two, and how a wheel loader works explains why the load transfers the way it does.
Tyres also tell you about a machine’s history, which is why they are on every used-machine checklist. Uneven wear across a pair usually means the machine has been worked hard on bad ground or run at wrong pressures for a long time. The used wheel loader buying guide sets out what else to check, and fuel tank and oil capacities covers the service side.
