Need advice asap
 

So long story short i have a slashed tire and need to get my Z to a shop. Would it be a bad idea to put the spare donut tire on the rear with the differential? Will it heat it up too much since the tire diameters will be off? Thanks for the help

Why have a spare tire if you couldn't use it? :dunno:

Use the spare. Do you think it was designed for a front tire flat only?

I suppose you could put a good front tire on the back, and put the spare on the front.

Either way, don't drive faster than they recommend, and get the regular tire fixed as soon as you can.

I get what your asking about the VLSD potentialy being damaged, all of the above responders obviously do not. Yes i would swap out one of the fronts to the rear and put the donut spare on the front. I am assuming you have 19" or 20" wheels on your z for you to be concerned about this. If you have rims with the OEM rim diameter than it would not matter.

You're not supposed to drive on a spare more than 50 miles or 50mph. The owners manual doesn't say anything about VLSD problems.

Ya I've asked around to some of the Nissan dealerships and some are telling me not to use the spare on the rear and some are telling me that it's ok to use the spare only for a low speed and short distance. I currently have the 18" track wheela on it. I just ordered a set of 20" matte black Giovanna kilis that are on the way.

Thank you guys for the help... One of the Nissan service managers was telling me to not put the spare on the rear with the differential even with stock wheels. We all know that they are frequently wrong so I just wanted to double check with you guys. I only have a 15 mile drive to the shop I am taking it to.

Why would you assume we didn't "get it"? Maybe we did, but didn't mention it because it makes no difference as long as you follow the OM recommendations for low speed operation and getting it fixed ASAP.

You need to calm down buddy and not get your panties in a bunch.

You can safely run the spare on the rear. As Dave mentions, keep the speed low. If you have TCS or VDC, turn this OFF.
