What This Size Means

245 = tread width in millimetres. 75 = aspect ratio, meaning the sidewall height is 75% of the tread width (184 mm). R = radial construction (or bias-ply if dash-indicated). 16 = wheel rim diameter in inches (406 mm).

Editor's Technical Insight

The Mahindra Thar is India's most celebrated recreational 4x4, rolling on purposeful 255/65 R18 all-terrain rubber on LX trims (and 245/75 R16 steel wheels on AX Opt models). The factory 18-inch tyre boasts a generous 166mm sidewall height and a 31-inch outer rolling diameter, delivering 226mm of unladen ground clearance and a 650mm water-wading threshold. While the stock MRF Wanderer or CEAT CrossDrive tyres balance highway refinement and casual trail traction reasonably well, serious off-road enthusiasts frequently transition to more aggressive tread patterns like BFGoodrich KO2 or Maxxis Bighorn. For deep sand driving in Rajasthan dunes, airing down the tyres to 18-20 psi elongates the contact patch dramatically, allowing the Thar to float over powdery sand without bogging down; however, remember to reinflate to the factory 32 psi before returning to highway asphalt. The Thar's live rear axle and high body-on-frame stance make front-end wheel alignment sensitive to hard trail impacts: check toe and camber every 10,000 km to prevent asymmetric feathering on the front outer tread blocks.

Frequently Asked Questions

Can I install 285/60 R18 tyres on my Thar without lifting the suspension?
Yes, 285/60 R18 tyres fit on factory 18-inch rims without touching the chassis during straight highway driving. However, during extreme cross-axle off-road articulation, the wider 285mm section will briefly contact the inner front bumper lip and plastic wheel well liner unless a minor bumper trim or 1-inch leveling spacer is fitted.
महिंद्रा थार में सड़क और ऑफ-रोडिंग के लिए हवा (टायर प्रेशर) कितनी होनी चाहिए? (Mahindra Thar tyre pressure)
Mahindra recommends 32 psi on all four tyres for normal highway and city driving. For off-road loose sand driving (रेत में ऑफ-रोडिंग), air down to 18–22 psi for greater flotation, and reinflate to 32 psi before driving on paved roads.
Are 16-inch wheels better than 18-inch wheels for hard off-roading on the Thar?
Yes — 16-inch wheels with 245/75 R16 or 265/75 R16 tyres provide a taller 184mm sidewall cushion, allowing greater flexibility when aired down, significantly reducing rim damage risk, and providing a wider selection of aggressive Mud-Terrain (M/T) tyre options.
Does the 5-door Thar Roxx use a different tyre size?
Top variants of the Thar Roxx feature 255/60 R19 tyres on 19-inch alloys, while mid-spec Roxx trims use the familiar 255/65 R18 configuration.
