Wheel cross reference

[McFarmer]

So our son has a Fiat, seems it has no spare tire. He is out west right now and doesn’t feel comfortable driving out on the back roads without a spare.

Very few Fiats in the salvage yards out there. Is there a chart where we could see what other makes use the same wheel pattern ? I’ve looked but have come up dry.

Thanks.

Tirerack... shop for wheels, plug in the make, model, year, and sometimes more info and it will show valid choices which will have specs like bolt pattern, hub diameter, offset, etc.

You could have half a dozen different wheels with the same bolt pattern and still have none of them interchangeable. On a particular application, not only do the diameter and width need to match, but also the offset and the configuration of the center disc as necessary to clear the brake calipers.

You'd stand a much better chance of finding the correct wheel at a tire and wheel shop where people have left their oe steel wheels behind when they put custom wheels on their Fiat. Also, if you search eBay for Fiat 500 steel wheels, there's piles of or wheels on there for $60-$70 each.

In addition to everything said above, you also need to pay attention to the center bore diameter for hub-centric wheels. For example, both my 1962 Olds F-85 and a similar vintage Ford Falcon use the same 4 x 4.5" bolt pattern, but the Ford wheel won't fit my Olds due to a smaller center bore on the Ford. Since you didn't tell us year, model, and current wheel size, there is no way to provide useful info. Also, is the original spare a full size or a donut spare? The wheel will be different, and a full size may not fit in the storage area if the factory spare was a mini.

Finally, when was the last time anyone here really needed to use a spare tire? In 45 years of driving, I think I've had to change one tire while out on the road.

Last summer.... AND even with never seize on the lugs and hub, the wheel had stuck to the hub since I had changed the snow tire out for the factory wheels and tires maybe three months earlier.

I have never been stranded by a flat (and most of my cars have no spare but do have TPMS), but I also carry a 12V compressor in every car and have often used it to top up a low tire that has a nail or screw in it before I can get it repaired or replaced. Modern, good quality tires don't fall apart from minor damage if you keep them at the correct pressure.
Now if I were going off-roading or were worried about actually breaking a wheel (like if I were going to drive through Jersey) then I would have a spare.

Which reminds me. If anyone ever touches your wheels, retorque the lug nuts as soon as you get it back. An otherwise good body shop had to replace a damaged wheel on my wife's car and when I got it back I had to use a breaker bar to loosen the bolts since they had torqued the piss out of them.

Got two flat tires at the same time year before last, got two flat tires a day apart a few years back, got a puncture in a run flat last year, had to buy two new ones, got a flat on the fork lift a few months back (that was a fun one to repair), got two flats on trailers and got a flat on the inner tire on the Ford f350 about 6 months ago .... I get loads of flats. For my daily driver I have a donut spare and a full size spare.

You lost me at, "our son has a Fiat"

I have a Fiat 850 1969 the typical Fiat bolt pattern is 4x98mm - not many other cars have that. What year is his Fiat?

I generally use this for other cars

Years ago, maybe 50, I read a sign in a tire shop "80 percent of flat tires occur in the last 10 percent of a tires life".

True tires are better than they used to be; does anyone else remember Firestone 500 tires?

My personal experience with FIAT cars is that your son would be better off with a Yugo.

I also use wheel-size.com to know the oem size, bolt pattern, offset, etc. Their info is very accurate. Once you're done figuring out the correct specs for your wheels and you want to get aftermarket ones, try 4wheelonline. They have a nice selection of wheels.

Also, check out fiatforum. You might get good recommendations from this forum.
