Spare Tire size for Nizmo

Chiefish · 05-01-2015, 08:23 PM

Does anybody know the correct spare tire size for the Nizmo? I was looking into a Wicked CAS Magic Box when I stumbled across a blurb about the Nismo/Sport has a 19" Spare. I looked at my spare today, and sure enough it was 18". Did I somehow get the wrong-sized spare? If I had to use it in an emergency, would it hurt my rear diferential? Does anybody have a 19" spare? Is it really made of "Compressed Aluminum" as I read somewhere? Looking for answers.

don't have a nismo, so i can't answer your question about 19" wheel on the spare, but figured i'd chime in since there haven't been any responses so far.

in practice, what you'd need to be concerned about is how closely the wheel and tire are in comparison to the original tire. I'd expect the spare to be about 26" in total diameter give or take. never taken the spare out to measure it though. the large difference in diameter is what would lead to sensors going whacky and might put some stress on your diff.

it should go without saying, but as with any car, it's not wise to run the spare for longer than 25-50 miles. they aren't meant for prolonged use no matter what the diameter.

also, i'd be really surprised if Nissan put a different spare in for the Nismos. then again, it wouldnt be the first time i was surprised by Nissan's decisions.

The 18" and 19" OEM wheels all have tyres with very similar overall diameter and the spare is similarly sized at 677mm or 26.5", so no issues for the diff.

thanks for your inputs.
i've read on other threads about the nismos having a different spare....something about a a subwoofer fitting in a base model wheel well, but not in a nismo/sport.
