Driving With `spare Wheel` Different Size To Rest R32Gtr

[blueboost20]

if i get a flat tyre and have to use my spare will it damage diffs,or whateva if i have to drive the car and its a different diameter to the other 3 wheels??

The spare should be the same rolling diameter to the other wheels lest you burn out the transfer case.

It is recommended that if you have to use the spare, put it on the front.

Less chance of damaging driveline due to the front diff being an open differential, so wheels can freely spin at different speeds.

If you put it on the back, you'll probably burn out the plates in the limited slip diff...

So if you've got a puncture on the rear, put up with the fact that you'll look totally stupid putting the spare on the front first to get that front wheel; attracting comments like, "Oh look at the 2 digit IQ mechanic! He's replacing a totally good wheel with a spare & he doesn't even realise he's got a flat at the back!" > guffaws

80 Km/hr speed limit on the spare BTW and you may feel the car brake (or steer) slightly to one side

Guess if u had a flat in the rear, put good tyre from the front to the back, then spare at front

Would be abit annoying changing 2 tyres on the side of the road

If your car has a good chassis, jacking up one side should lift both front and rear wheels on that side at the same time!!!

I considered doing it once, then remembered I had RACQ (Queensland road assist), poor fella.

I always assumed two proper wheels on the front would be beneficial somehow, also my front brakes don't allow for the spare to fit over the caliper.
