Full sized spare

[blueSup]

A couple of posters have mentioned they requested a full sized spare when they purchased the 162TSI Superb.
Were those requests fulfilled?

If my mathematrickery is correct, the 18x8 235/45 on the 162TSI is 668.7mm in diameter.
The 19x8 235/40 on the 206TSI is 670.6mm in diameter yet the car carries a dainty space saver spare.

To me, that 2mm difference means I'd probably fit a full sized spare in the wheel well if a full sized spare fits for the 162TSI.
Any thoughts or pictures of such?

I've just gone and had a quick look at mine, as from a quick glance at it and seeing it had a real tyre and not a slim donut I assumed I had a full size (never asked for it, bought a demonstrator so take what you get)

However it is a normal 205/55/16, on a normal steel rim, but with a big 80km/h restriction sticker on it like you see on a donut 0_o. Is that what others with the 19"s from the tech and image packs got? That's a 6.2% difference in diameter from the 235/40/19 so I guess that's why they put the warning sticker on...

One of the issue with spares is not the diameter, but the height.
i.e a 235 tyre will sit up 30mm higher than a 205 tyre, in the spare tyre well in the boot.
That extra height will compromise the boot floor from being level/flush.

I have a full size alloy spare in my 206 & it is the same 245 size fitted to my car. You are right it sits higher than a 205 but not as much as you calculate. A 205 is under the well top, so the 245 sits about 1.5 cms higher. It was the same in the 3TV6. When I first put the boot floor back, it sat a fraction higher for a few days, before settling very slightly higher in the centre but I would defy you to pick it unless someone showed you the bigger wheel underneath.

If you look in the boot of the sedan, there is a black plastic trim on the inside rear of the boot with a 12mm lip on the bottom. I needed trimmed a tapering semi circular piece out of the middle of that trim to make the wheel with 245 tyre lift in & out easily, without any fouling. You need to do the same to a lesser extent for 235. Why a lip on a piece of plastic trim intrudes into the well area is beyond me. The other thing one needs to do is take a knife to the foam tool block & remove the foam batwings Skoda use to to fill the empty space left around the billycart wheel.

I've had to use my spare twice now, both time out in country areas where there are no tyre traders stocking 235 or 245 for 19" rims. I have a genuine Skoda 19" alloy for the spare, courtesy of my mate buying from Superskoda's clearance in Prague, in April 2016 & bringing it back for me. Out here Skoda dealers quoted me three times the price in Europe & the prices were NOT consistent across the dealers. Sydney Skoda dealers quoted from $988 to $1,387 for the same 19: alloy! It would be much easier & cheaper to just buy a right size & offset new wheel which looks similar from somebody like Jax or Beaurepaires etc. My old school mate who runs a tyre dealership tells me he sells at least 30 wheels a month to customers wanting a full sized spare.

Personally, I'd like to see these so-called 'spacesaver' wheels banned. The official reason Skoda claims not to supply a full sized spare in the 206 is it was to reduce weight to get the car under 6secs. I weighed the billycart wheel & the alloy. Their excuse is rubbish. Those steel wheels with higher profile tyres aren't light. It is just cost saving, for them.

When I get a chance, I'll take a couple of photos to add into this.

Thanks for the info 2009fsi.
I had an idea the boot floor might rest on the bigger rim. Now to find the time to see how it all fits.

Confirmed: No full-sized spare in the wagon without some cosmetic surgery to the inside plastic edge of the sill. Plus it does sit higher and you need to protect the face of the rim from the floor of the wheel well.

For these reasons I decided to just buy a 19 inch mag for $250 and put on the same Pirelli P7 as is on the car already so there should be no issues using it as a spare at all.
When the fronts are worn then 1 can go to spare and i only need to buy 1 new tyre
I was just going to put the wheel in the back of my wagon on trips away from the city but in the end i have it in permanently as it doesnt take up too much room - i fill it up with gear and i have a box on top of it also

It seems that we should be almost grateful that there is a reasonable wheel well provided these days.
Looking at BMW then run flats are an incredibly expensive and compromised solution.
Inflation and goo canisters are possibly even worse, especially if you are the poor tyre bod that has to replace it.

At least the 'space saver' tyre provided is a reasonable size. I used it on my Octavia and it got me out of a mess very late at night in deepest South Australia.

When you look at the enormous tyres fitted to high performance SUV's (eg X5 or X6) there is no way a full size spare could be fitted in the vehicle and I dread to think of the effort required to actually change them, not that the owners are likely sink to that level, or go far out of town.

The "full size" spare in the Superb is a 205/55R16 (IIRC - haven't checked in months) - its the same overall rolling diametre as the Mk2 Superb; Mk2 & Mk3 Octy, etc etc. Not the same rolling diametre as the Mk3 Superb.
Full size tyre, yes (205) but not full size wheel. As such, only suitable for doing the posted 80km/h.

The other main problem is you can't fit a 225 or 235 tyre under the boot floor, so you can't buy another Superb alloy and use that as a spare... (Not that you'd want to, super heavy!)


EDIT:
There is only so much room around the wheel, also. I'd hate to have my spare wedged in the spare wheel well so hard it'll never come out! Ick!
