That's part why I wonder if the shelf life of a donut spare that's kept protected is better than a conventional daily-use tire or not.Bob Lincoln said:The original donut spares in both my 84 and 93 Daytonas are in great shape.
The full-size spare underneath my 92 Dakota had deteriorated enough by last year that I bought a new tire. People thought I was foolish to invest in a new tire, especially since I drive it about 3K to 4K miles a year, and don't have occasion to rotate them. But it's crazy to have a spare and for it to be non-functional. It's good insurance. And I winch it down at least once a year to be sure the winch works and I can actually get at it.
When I bought the Impala it still had its original tires on it, as the car had less than 7K on the odometer. I had the tires changed before I drove it on the freeway or extensively. It came with a 15" steel wheel with conventional-seeming tire as a sort-of full-sized spare, when I pulled that wheel out to replace it with the factory 17" wheel and tire that I acquired I think my placing it on the floor of the garage was the first time that the tire had been on the ground or even out of the trunk since that car left the factory.
Some of the T-bucket hotrodders like using the donut wheels with replacement tires on their rat-rods, but with the replacement tire it's not unsafe.digitalrailroader said:I've only had a blowout once in the 5 years I've been driving, and it happened in the Breeze; I had picked up a piece of metal from the parking lot at the Technology Center when i was getting my Automotive Degree, and it had actually blown out the sidewall. a little bit after that, I went to the local Pull-a-part, and picked up a full size 14" Steel wheel, and had a Brand new tire put on it; that Full size Spare has NEVER Seen Road Ever Since I put it in, because after that, the Breeze's engine Blew Sky High. of course, all Three of the cars we drive now (Dad's Silverado has a full Size 17" spare, The Breeze's Replacement has a 14" Dunut, and my mom's SX4 has a 15" Dunut) the Spares in them have NEVER Seen Pavement (and Hopefully NEVER Will) but one of my Pet Peeves when driving is seeing people driving on a Donut Spare as if its a Full Size Spare! (the Automakers need to put BRIGHT RED Warning Labels on the Space saver Rims that say DO NOT USE YOUR SPACE SAVER SPARE TIRE LIKE A FULL SIZE SPARE TIRE!)
I've heard that the XJ Cherokee donut spare tire is a good spare for sixties and seventies RWD Mopar cars, anyone tried this?
