The Bada Dost tyre size depends on the version: 215/75 R15 LT tubeless on the i3, i3+ and i5 family, and 7.00 R15 LT 12PR tube type on the i4. Every Bada Dost rolls on 15 inch steel wheels, with one size on both axles.
Because Ashok Leyland sells many payload and deck versions, owners often get the wrong tyre quoted at the shop. Use the chart below, then confirm with the sidewall of a tyre on your own truck.

Bada Dost tyre size chart
| Version | Front | Rear | Wheel |
|---|---|---|---|
| i3, i3+, i3+ XL | 215/75 R15 LT (tubeless) | 215/75 R15 LT (tubeless) | 15 inch steel |
| i4 | 7.00 R15 LT 12PR (tube type) | 7.00 R15 LT 12PR (tube type) | 15 inch steel |
| i5, i5 XL, i5+ (LS, LX) | 215/75 R15 LT | 215/75 R15 LT | 15 inch steel |
One comparison listing shows the i5 LS on the 7.00 R15 size instead, and we did not find a published size for the i6. If you own either, read the sidewall and tell the shop exactly what is printed there.
Two very different 15 inch tyres
215/75 R15 LT is a modern metric size: 215 mm across the tread, its sidewall reaching about 161 mm (75 percent). Standing height comes to 381 + 322.5, roughly 704 mm. LT marks a light truck build with a stronger carcass than a car tyre.
7.00 R15 LT 12PR uses the older inch style marking. 7.00 is the section width in inches, R15 the rim, and 12PR a ply rating that tells you it is built for heavy loads. It runs with a tube. The two sizes need different rims in practice, so do not mix them on one truck without dealer advice. The tubeless vs tube guide explains the repair difference.
Load rating matters more than tread pattern
A Bada Dost often runs close to its payload limit every day. When you buy tyres:
- Match the load index or ply rating on the old tyre. A car tyre in 215/75 R15 is not the same thing.
- Keep the same type on all four corners.
- Ask for a highway rib pattern if you run long distances, and a block pattern only if you work on mud and farm tracks.
See the load index guide for how numbers translate into kilos per tyre.
Pressure for a loaded Bada Dost
We did not find a published pressure we could confirm twice, so this Bada Dost page leaves the number out. Ashok Leyland prints it in the owner's manual, and commercial vehicles usually carry a higher rear figure for full load. Check cold, early in the morning before the first trip. An under inflated LT tyre with a full deck flexes and overheats, which is how sidewalls fail on highways. Use our pressure converter if your gauge is in bar or kg/cm2.
Making Bada Dost tyres last
- Load only what the RC allows; each extra quintal on a Bada Dost deck shortens tyre life.
- Rotate every couple of services so the rear pair does not wear out alone. Our rotation guide shows the pattern.
- Check for stones stuck between the tread blocks after quarry or construction site runs.
- Any sidewall swelling or deep gash goes to a tyre dealer before the truck carries another load.
- Fit new tyres when the grooves meet the wear bars or the DOT stamp shows roughly half a decade of age.
Bada Dost tyre size versus the smaller Dost
Owners of the lighter Dost and Dost+ should open the Dost tyre size page; those trucks run smaller 14 and 15 inch LT tyres. Their wheels are not interchangeable with the Bada Dost. Ashok Leyland rivals, pickups and vans all branch off the car and van tyre size hub, so start there for a mixed fleet.
Questions owners ask
Which tyre size fits my Bada Dost?
The i3, i3+ and i5 family take 215/75 R15 LT; the i4 takes 7.00 R15 LT 12PR. Every version runs 15 inch steel wheels and one size on both axles.
Is the Bada Dost i4 tyre tubeless?
No. The i4 is listed with 7.00 R15 LT 12PR tube type tyres. Puncture repair means fixing or replacing the tube.
What tyre does the Bada Dost i5 use?
Most listings give 215/75 R15 LT for the i5, i5 XL and i5+. One listing shows 7.00 R15 for the i5 LS, so check your sidewall.
Can I use car tyres of the same size?
No. Fit LT tyres whose load figure is no lower than on the Bada Dost originals. Car tyres are not built for a pickup's load.
Where do I find the Bada Dost tyre pressure?
Ashok Leyland prints it in the Bada Dost handbook, and a cab sticker may repeat it. Measure before the first trip and switch to the laden value when the deck is packed.
When are Bada Dost tyres finished?
Once Bada Dost grooves meet the wear bars, the sidewall shows cracks, bulges or cuts, or the DOT stamp points to roughly half a decade of age.
