Fitting Full Size Spare... there's room

[veew]

Cheers mate.
I've got 6 months to wort it out so I will take my time to make the right decision. Good idea about putting the actual 20" wheel in the wheel well, see how high everything sits.

That's what I did in my gen1 Tig. I put a full-size wheel in and the (modified) boot floor ended up sitting flush with the boot lip so worked pretty well.

I had to toss the original solid floor and make a new floor that just covered the top of the tyre. The standard floor sat too high otherwise.

Just an update, I ended up buying a OEM steel 17" rim ($165). Will get Pirelli Scorpio Verde 215/65 R17s fitted next week. Thanks for all the help and advice!

Tyre fitted, boot floor sits without any problems.

Damn it, just found this ad:

https://www.gumtree.com.au/s-ad/littlehampton/wheels-tyres-rims/2017-vw-tiguan-tulsa-17-alloy-rim-and-tyre/1165255341

Would've bought these if I the ad was around 2 months earlier (didn't see it despite the ad stating listing was Nov 2017). Not far for me to travel to get it either.

Do you know if you can fit a Full Size 18" spare to a MY18 Tiguan 162TSI ?

The VW steel full size replacement 17" rim is narrower than the Tulsa 17" rim and also the other larger tyres in the range. It would probably result in the floor sitting on top of the tyre and create a load lip.

I'm surprised Tiguans don't come with a full size matching spare to start with! And re the OP, there's a few different options for large wheel, low profile snow chains these days... Check these ones out for example or these ones. And if ever the government catches up with technology, we'll have even more options. Especially in Australia's pathetic snow season.

Sad that the Highline 162TSI comes with 18" as standard but the num nuts in Germany are saving pennies and didn't make the wheel well 1 inch deeper to allow for an 18" spare if all the other wheels on the 162TSI are 18"

Dunkoff!

Right I've been doing some more investigation into this issue as I'm looking to install a "full-size" spare in my Sportline.

After reading the Owners Manual and discussions with VW Customer Care / VW Service Manager the result is that to run without any restritions you have to have a matching tyre on your spare.

According to the owners manual:

"If the spare wheel tyre is not the same as the tyres that are mounted on the vehicle" then it says "the spare wheel must be used only in the event of a tyre failure and for a short time"


Further it says:

"Follow these guidelines:
- Do not drive faster than 80km/hr (50mph)
- Avoid full acceleration, sudden braking and driving fast through bends in the road
- Do not use snow chains on the temporary spare wheel
- The tyre pressure must be checked as soon as possible after fitting the spare wheel or temporary spare wheel"

So basically if the tyre on your spare doesn't match the other 4 tyres on your car you technically can't drive your car over 80km/hr.

If you want to drive without any restrictions then you ideally would have a fully "matching" spare (best case) or the alternatively an "unmatching" rim but matching tyre.

I priced up a 20x8 Kapstadt rim from the dealer and they wanted $2,331 for a single alloy. Alternatively they did have a much more reasonably priced Kapstadt "Accessory" wheel which was $638. It's a different part number to the stock alloy and believe it comes in a slightly different collour but size/offset specs are identical. I may see how I go fitting it in the boot, however I think I may still be looking at going down the "Steelie" route or at least find a 17" rim and modifying the boot floor to accomodate it.

If you're going the steelie route then might as well get these for similar money. Thought they would have sold all the tyres by now.

The way I see it the steel 17x6.5" wheel is the only guaranteed way to fit a full-size spare under the floor without modification. The OP of this thread already tried fitting a 17x7" Tulsa and the floor didn't (quite) sit flush. Even though it was running the same tyre the extra 0.5" in rim width was all that was required to go from fitting to the boot floor being raised a couple of mm.

I'll test fit one of my Kapstadts this morning and then decide which route to go down. The way I see it I've got 4 options:

1 - run the stock space saver (80km/hr and 200km limit)
2 - get a steel 17x6.5" rim and 215/65R17 tyre (confirmed to fit, however 80km/hr limit if you're not running 215/65R17 as standard)
3 - get a 17" Tulsa and look to modify the floor (still 80km/hr limit on Adventure/Highline/Sportline/R-line)
4 - get a full-size matching wheel and make a new boot floor (no speed/distance restrictions)

Fitting Full Size Spare... there's room

OK so I've taken one of the Kapstadt ( 20x8 ) wheels off and test-fit it in the boot. As suspected the boot floor sits up on top of the wheel. The top of the wheel is just under the lip of the boot though so making a new (thinner) floor is still an option.







I also lined the spare up against the stock wheel and noted there's quite a difference in diameter (which is another reason to get a full-size spare).
