I was hoping one of the resident experts could answer this one for me???

I have always been led to believe that in a 4WD car you had to run the same rolling radius tyres front to rear, otherwise it would damage the centre diff!!!

Is this true and if so, how come I have a 16" space saver in the boot of my MY01 Bug eye whuch runs 17" as standard??

Thanks in advance,

Chris

 

Because the tyre size is different on the 16inch rim giving similar rolling radius and is one of the reasons there is a speed restriction stamped on the space saver.
