Have bought a second hand Almera (year 2007) and am horrified to find a space saver in the boot. My 'dealer' says there are difficulties getting a reasonably priced full sized wheel hub and tyre to replace it. I do a lot of mileage - could be 1000km in a week. Am I worrying unnecessarily or should I persist? What price should I expect to pay for a full sized replacement wheel and tyre?
