Fitment Advice & Size Verification

4.00-8 6PR is the standard front and rear fitment on the Bajaj RE Compact, TVS King, Mahindra Alfa Passenger and Atul Auto Gemini. Because three-wheeler rims are small and the tyre is tube type, the valve must be replaced with the tube and the rim bead seat checked for rust before mounting. Keep the cold pressure at 32 PSI solo and 35 PSI with a full passenger load - a soft tyre on a CNG auto raises fuel consumption and wears the shoulder unevenly. If your auto runs a different code, we will read it off the tyre for you at the workshop.

Note: Always verify your vehicle door jamb sticker, fuel lid placard, or existing tyre sidewall markings before purchasing. For safe handling and speedometer accuracy, overall rolling diameter should remain within ±2% of original manufacturer fitment.

Frequently Asked Questions

Expert answers for 4.00-8 pricing, pressure, and warranty

A 6PR casing is the standard for passenger CNG autos running this size, and an 8PR 4.00-8 is the correct choice for cargo three-wheelers that carry heavier loads. Using too low a ply rating on a loaded vehicle causes the casing to flex, heat up and separate at the shoulder.
Almost all 4.00-8 6PR and 8PR tyres in this size are tube type, because the 8-inch steel rims on three-wheelers are not tubeless-compatible. We always fit a fresh tube and valve with the tyre and check the tube for pinhole leaks before refitting.
New 6PR 4.00-8 tyres start from ₹1,100 at Sahara Tyre GIDC, and 5-point safety tested used tyres are available at roughly 25% to 40% of the new price. Fitting, tube replacement, valve replacement and balance are included in the quoted price with no hidden charges.
