I RECENTLY replaced the front tyres on my 2003 Mitsubishi KJ Verada AWD because of unusual wear on the outer edges of both. The tyre retailer claimed the wear was caused by under-inflation. I regularly check the pressure and run the tyres at the maker's recommended pressures of 29psi front and 26psi rear. The retailer said I should inflate them to 32psi front and rear. Who do I believe? Given that tyre gauges at service stations can be inaccurate, what is the best way to ensure a tyre gauge is telling the truth?
BOTH maker and retailer are actually correct. The Mitsubishi pressure takes into account ride comfort, handling, noise and tyre life and is usually a compromise. The tyre retailer gives you a recommendation for better life and handling, but the ride may be harsher and road noise higher. I'd be happy to follow the 32psi he recommends. I prefer to run pressures slightly higher than those recommended by makers. Use your own hand-held gauge. Go to your tyre retailer and check it against the gauges there. Forget about servo gauges.
