TYRE WEAR

Early tyre wear and road noise problems were attributed to the variance in the front rear axle drive ratios and their combined effect on the viscous coupling. The revised IRD drive ratio from 2001 onward appears to have eliminated the problem on these cars.
It’s easy to jump the gun and blame the transmission for tyre wear, but freelanders suffer normal tyre problems too. For example, over inflation wears the centre of the tread, under inflation the outer parts. Incorrect tracking at front or back (rear tracking is adjustable) can cause both tyres on an axle to wear on both outer, or both inner edges.
Suggest driveline problems, and it’s usually this wear pattern that causes excessive road noise. Check suspension links, bushes and dampers are serviceable before blaming tyre problems on the driveline. Use same size tyres front and rear and keep newest tyres on the back.
