THE factory original Goodyear tyres on my 2007 BF Ford Falcon need replacing after 41,000km. I understand this is about average for a car of this size. I have obtained three quotes and they come in between $1080 to $1260 fitted and balanced for a set of four. I got a fourth quote for a similar tyre named Rockstone, which I understand is made in China and about half the price of the Goodyear. The dealer assured me their driving characteristics were similar to the Goodyear tyres, and they were rated higher at 98W. I have never heard of them. Are they safe? Do they have good tyre life?
Joe Briffa, email Little is known about the Rockstone brand, so it’s not possible to advise on their safety or potential life. There is no doubt, however, that you would be compromising somewhere, either in the performance, noise, ride comfort or life. The best advice is to shop around for a known brand of tyre that still gives you a saving over the Goodyears.
AFTER a battery change, the malfunction indicator light (MIL) in my 2005 Nissan X-Trail came on and the engine went into ‘‘limp’’ mode. After checking online, I found the computer on the X-Trail could be reset by removing certain fuses for a short time. Feeling very clever, I did this, and sure enough, the MIL went off and the car came out of ‘‘limp’’ mode. However, it was noted by my ‘‘cyber guru’’ that if the fault were more serious, the MIL would come back on, which it did! Are you aware of any on-board diagnostic code reader I can get for my car so I can identify and rectify the problem without going to the dealer?'
Paul Ditchburn, Parkdale I’M not aware of any affordable equipment you could buy to diagnose problems at home. If you want to save money you could use an independent service agent who would generally charge much less than the dealer.
Safety worry: a Falcon owner is looking for cheaper, quality tyres.
