spare tire and patched tire questions

280z/300zx · 01-24-2011, 01:02 PM

So recently had a flat and thought I'd see if anyone has the answer to the questions I've always wondered.

How many miles does the spare last? In my case I had to put roughly 100miles on it. It was unavoidable due to the location where the flat first happened. Can I still use this spare later on or should I order a new one from Nissan?

With a patched tire how safe is it under racing conditions? I don't do anything crazy but should the car exceed 100mph is there going to be a problem? Also I auto-x occasionally, is this okay? The tire shop said it was fine but the kid was no older than 18years old. Just want to make sure that the patch will hold. Thanks

i thought donuts were rated for 100miles at 50mph max? but our donuts are bigger so not sure. i suppose you can continue to use for emergencies as long as it's pressured up (60psi) and no cracks or anything on the sidewall and treads.

about the patch in race conditions... hummm... really depends on the condition of both the tire and track. ive had both plugs (the ones you push-in from the outside) and patched tires in the past and they lasted the full tire life. no racing, but spirited driving on street.

The manual is your friend

The Warranty Information Booklet on page 22 says the Spare Tire is good for up top 3,000 miles. The Manual says replace the spare tire when the wear bars appear.
