458 Spare Tyre

i dont lnow but i am also intereseted to know this.

 

I found this old photo here http://www.ferrarichat.com/forum/141635438-post8.html

Baggage might be limited !

Look-alike means researching other cars using the bolt pattern and then seeing what might work on offset

 

Mel u just need to find the smallest rim that would fit over the rotor.
Bolt pattern is 5 X 114.3 mm

 

I would do the measurements.
And just buy the cheapest rim that will fit the pattern.
And that way u feel safe in that just in case situation.

 

Here goes a example
ENKEI 379-895-6515SP Silver RPF1 18x9.5 Wheel 5x114.3mm Bolt Pattern 15mm Offset | eBay
This is a 15 mm offset should work...but I will look get u the right offset.

 

Here u go
458
Five Spoke 20”, 5 X 114.3 mm
Front 8.5J X 20 ET 46.5mm, Rear 10.5J X 20 ET 58.5mm
So u would need a atleast 8.5 rim width and most likely u can use 46.5 offset on the front and back.just need to clear rotors.
Scratch the previous post.

 

Keep in mind that Ferrari wheels are hub centric; this means the wheel indexes off the center hub diameter, not just the location of the 5 lug bolts. So, in addition to the correct bolt pattern, you'll also probably want a wheel which has a center hub diameter that is compatible with Ferrari's 67.1mm hub size.

Correct Ray ...I didn't think about that.
Melvok 7 would work.

 

If the hub of the donor car is larger that that of the Ferrari's hub, there is a remedy. The aftermarket wheel industry deals with concentric hub rings to overcome mis-matched hub diameters. On the other hand, if the donor car's hub diameter is smaller than 67mm, that wheel will obviously not work. Some people do not like hub-centric rings, and while I am not a big fan of them, for temporary spare tire use I would consider it.

 

I like the hub centric setup also.

Another point to keep in mind is the thickness of the rim at the lug bolt location. With a normal car, you have studs and can mount just about any thickness wheel and take up the slack by threading the lug nuts further or less onto the wheel studs.

With the Ferrari, it's lug bolts, not nut. As such, the tolerances (specifically rim thickness where it mounts) become much more critical.

If you just toss a temp spare off a Honda or Toyota or something into the luggage compartment, you might be in for a nasty surprise should you ever have to mount it on your car in the dark. If the rim is too thin at the mounting area, there may be no way to clamp it down, as the Ferrari lug bolts are generally not fully threaded on the bolt shaft.

Make sure you do a test (and make sure the back of the bolts don't stick through the hub and interfere with the brake hose mounting plate, etc, etc.)

Myself, I don't carry a spare. But I'm darn handy using a plug repair kit on the side of the road! Just make sure you have the T-handle version, because the other kit is nearly impossible to use.

The plug repair kit?

Ray

 

That's the basic idea, yes.

Here is the one I carry in the 458, as well as my other cars.

Some important notes, however:

First and foremost, is you want the T-handle version, not the normal handle. The reason is that without the T-handle, it's darn near impossible to produce enough force to penetrate the tire effectively. You need to ream the hole out to the size of the tool, which requires a great deal of in/out force against the tire. Due to this, you almost have to have the T-handle in order to be able to pull and push properly.

Second, with regard to the insertion tool, you want one that is high quality and more symmetrical than the one you have shown. You will also want to carry a flat blade screw driver, which will generally be required to help pry open the fork tool at the end (allowing you to insert the sticky sealing string thing). You probably will also want to carry some needle nose pliers, since often times pulling a broken off nail out of a tire is no easy task.

Again, with the insertion tool, you'll definitely want the T-handle version, because you have to insert into the tire, which takes a great amount of force. You also have to remove the tool very quickly, leaving the sticky sealing string thing behind (think like yanking the table cloth out from under a wine bottle and dishes on a table sort of deal).

Once all this is done, you'll probably also want to have a very sharp switch blade handy, because you'll need to cut off the string which is hanging out.

Most of the kits include glue, but I never use it, as it only causes more trouble than it is worth. Generally, the sealing string thing is all you need and it sort of has its own glue on it already. I use the brown (slightly larger) strings, as opposed to the black ones usually.

Reaming the hole in the tire to the proper size is of utmost important, by the way. So make sure you don't skip that step. It seems counter intuitive to increase the size of a hole in your tire (when you are attempting to repair it), but it's required in order to get the sealing string thing properly installed.

You'll also need some sort of pump to re-inflate the tire.

It sounds like a simple job: just pop a sealing plug into a tire. However, if you have never done it before, be prepared. The first few times I did it, it was a nightmare of a job (even in a clean driveway, with all my tools available). I've since done it a number of times (usually for friends who are broken down and/or ex-girlfriends, etc.). Once you have done it a few times, and know the couple of little tricks that make it easier, it's not too bad. Usually takes all of 10 minutes.

Like I say, I carry this kit in every car I own. It can really be a life saver if you run over a nail or something and are far away from home or help.

My pleasure.

Never hurts to have a spare tire around. However, in my experience with flats and tire damage, 9 times out of 10 it's a leak or puncture as opposed to any sort of catastrophic tire damage which requires replacement. Usually running over something large enough to destroy the tire or rim is a function of poor driving and/or tailgating, etc. Usually what gets you is a nail or screw or something in the tire. In those cases, the puncture repair kits work wonders and are generally easier than having to replace a tire on the side of the road.

Also, keep in mind, in order to change a tire, you need a jack to lift the car as well as a wrench to take the lug bolts off. With the 458, lifting the car isn't always such an easy task, unless you happen to be carrying a full blown, low profile floor jack. As far as removing the lug nuts, I have a nice expanding 1/2 ratchet, but I don't bother carrying it in the car (unless I'm maybe going on a long trip), because I don't have a spare anyway.

Myself, I keep the road side assistance card in the car and have the tire repair kit for flat tires. Much beyond a flat tire due to a nail and I figure we are in deep water anyway.

I too prefer a real spare. When I had the 360 with 18" wheels, I lucked into a brand new OEM spare wheel for $350 and with the cost of the tire, I was set at $500 albeit a small donut.

When I upgraded to six-piston Brembo, that would not work so I sourced a reconditioned 19" twin-spoke wheel from a 430. While it took up most of the luggage compartment, it was a full size spare without speed or distance limitations. It did not match the Stradale wheels so there would've been hastened incentive to repair the tire, so as to not have mis-matched wheels.

I never used either spare. But you never know, because two weeks after getting my Infiniti, a screw decides to invite itself into the tread.

With the 458 there are only three options - pay an obscene amount for a OEM spare, carry a tire plug kit, carry a can of fix-a-flat. I currently employ option # 3, but this is my conundrum. Somewhere I heard or read the fix-a-flat contents will plug the tire pressure sensors, causing yet another unpleasant expense. Does anyone know if that is true and if so are the OEM sensors sold individually or as a set? Do you have to use Ferrari or will Discount Tire work?

 

Personally, I wouldn't want to bathe my expensive TPMS sending unit in any type of glue like sealant. This is why the push/pull plug repair is a nice method. Keep in mind, the 458 comes with a 12v air pump.

That's great!

I actually just used mine the other night. I heard a strange clicking noise when I drove out of the mall the other day. The window was down and ask I was driving near the wall, I could hear a tick, tick, tick noise echo back. Sure enough, when I got home, I discovered a nail in the tire. Used the puncture kit and was back in business in about 15 minutes.

Silly question but if having a spare is so important why not buy an original from the dealer? Or if you belongvto a local club get the club to buy it and borrow it if you go on long trips?
