2007 Suzuki Grand Vitara do front and rear tires have to be same size?
I just replaced 2 front tires and could not get same size as the rear. A shop
just told me it can damage my transmission. Is this true?
Yes, they should be the same size.
Do not attempt to use the 4 wheel drive if the front and rear tires are different sizes. This can damage the transfer case because the transfer case is geared for the front and rear axles to be turning the same RPM.
Any vehicle that has either 4WD or AWD must use the same size and make of tires, tread depth should all be within 2/32 of each other, this is more critical with a AWD vehicle.
Ok I got it.. thanks
