Evening all,

I have been reading through various posts about spare wheels and acquired a ‘space saver spare wheel’ which is 3.5J x 16 code HA42160927 with a T125/70R16
 

I read that the closest to a full size is 205/60/16.

 

Am I right that I can’t fit a 205/60 tyre on this rim and that I need to buy a different rim?

 

If so what size rim would I need and can I still use this spare as a spare?

 

Thanks

You can’t fit a 205 on that rim no.

 

your best bet if you want the almost right size wheel and tyre is just to buy one off a scrap car.

 

Both kinds of space saver whether the bike tyre or the almost full size still have max speed ratings and time you can drive on it.

 

you also need different foam and securing pieces for the boot as the size is different 

Thanks ApertureS!

 

When you say best bet to buy one off a scrap car what do you mean? Buy a 16inch alloy wheel or a full 205/65/R16 setup?

 

Noted about the speed and time factors, it’s intended use is only to get out of trouble and nothing major, so would this space saver be okay for that?

 

thanks  

One option for a spare wheel is 205/55R16 fitted to a 6.5Jx16 ET46 steel rim from the Octavia MK3.

A 205/55R16 tyre has an outside diameter about 5% smaller than a 215/60R16 tyre.

 

Therefore another option, might be 215/60R16 fitted to either a 6Jx16 ET40 or 6Jx16 ET43 steel rim. The idea of the narrow 6J width is to keep reduce the width of the inflated 215/60R16 tyre by about 6mm compared to fitting it to the standard 6.5Jx16 ET41 rim, as apparently a 215/60R16 fitted to the standard 6.5Jx16 ET41 rim does not allow the boot floor to fit flush.

If it’s just to be used as an emergency “get me to a garage” wheel, you’re as well just sticking with the space saver wheel. Getting a 16” wheel still comes with the same restrictions as the space saver. So unless you’re going to go and get a full size spare, just stick with the skinny one.

Driving with a skinny space saver could be dangerous, in the same way as driving with faulty brakes. You simply don't have much control over the car.

 

It's much better to use a more normal sized tyre such as 205/55R16 or 215/60R16, etc...especially when there is room in the boot for one.

Hence why there are speed restrictions and distance restrictions.

 

also you’re completely aware you have a spare wheel on because you’ve just fitted it.

 

any conscious driver isn’t about to go rally driving with it on 😂😂

 

driving with a fit for purpose space saver is in no way comparable to driving with faulty brakes.

If you saw a car fitted with a space saver tyre trying to avoid an unpredictable moose (ie. the moose test) you would see how wrong you are.

 

It's like saying a drunk driver who doesn't drive over 50mph is perfectly safe as long as the pub isn't more than a couple of hours drive away.🤣😁

Kent is known for its rampant moose population, so, yeah op. Buy a proper wheel. 👍🏻

If you look up the elk test (moose test) most cars begin to fail it at 43-50mph/70-80kmh.

 

So when the spare wheel is rated for 50mph only, at this point the car is already failing the elk test so the spare wheel will have a very minimal factor in it.

 

No one is saying a drunk driver is safe? And not once did i mention anything was safe, nothing about driving is safe in the slightest, metal shells held together with lots of single points of failure that can go at very high speeds,

nothing about it is safe.

 

it’s about working out risk and minimalising it as best possible. And that includes a space saver spare wheel, it is there to reduce the risk of you being in danger at the side of the road and allow you to either get to a place of safety or get to a garage because there is less risk than sitting at the side of the road.

 

Just shows people can argue over literally anything, it wouldn’t be in the car if it wasn’t fit for purpose.

that is real pain, when you to drive ~80 kms without Cruise Control

and have to keep less speed than flow

 

really can't understand where is problem, twice click on links i posted above -
Pros and Cons have been described already:

 

a)  same size as all other wheels
 + can be installed on any axle
 + can be used for longer distances
 + no size diff = no speed limits
 + Cruise control will be available
 - boot floor will be pushed few cm up
 - most expensive

b) custom 205/65r16 (my choice)
 + minor width diff will provide safe driving on + 30% of speed printed on spare disc. Important note, when installed on rear axle.
 + minor circumference diff will provide ability of Cruise control usage. In theory, i haven't had to use this spare after tire were changed.
 + fits in it's place, doesn't change size of boot.

c) OEM 205/55r16
 + lot wider than 'd' = safer than 'd', but don't think printed speed limit can be exceed more than + 10%, even when installed on rear axle.
 + fits in it's place, doesn't change size of boot
 - huge circumference difference disables usage of Cruise Control

 - huge circumference difference isn't healthy for 4x4

d) OEM 125/70r18
 + fits in it's place, doesn't change size of boot
 - huge width difference = absolutely unsafe, even when installed or rear axle.
 - huge circumference difference disables usage of Cruise Control

 - huge circumference difference isn't healthy for 4x4
