Non-Factory fitted rims/tyres

Featured Replies

Hello all,

Is anyone know a non-factory fitted rim/tyre set will be ok or is it guarantee violation at Skoda, also does it mean car modification for insurance company. I am thinking on a set of 175/50 16" what is almost the same diameter as the 175/65 14" factory fitted. Any advice ?

I don't think it will affect the warranty, but it will most definitely require a chat with your insurers. It can be a problem with some insurers even if you change between standard wheels from the manufacturer.

I'm not sure the tyres are wide enough.... we have 15's with 185/55/15 tyres (skoda fit option)

I'd go for 195/45/16 (0.51% RR difference)

or 185/50/16's (1.03% difference)

edit: your 175/50/16's are 0.68% difference, (which is fine!) but I would always take advantage of the extra size to get some extra rubber on the ground, with the 185's our citygo has more grip than you would think !

Thanks guys!

Sharkrider, is it 75ps do you have? Some citigo coming out with 175mm but i am not too sure. There is more rim/tyre option on 185mm that's for sure but looks like i am on the other side on 'grip vs. fuel consumption' war. Is that extra 10mm significant enough to have different/higher fuel consumtion i mean what is the difference, anyone tested ever?

it swmbo's car, a 60 ps SE loaded with every possible extra (it was a press car I believe) the 185/55/15 size is standard if you specify the 15 inch wheels....

its only done 3,000 miles so far, so has some loosening up to do, she just drives normally, and never gets less than 52 mpg so far... I did a 40 mile drive with economy in mind, and got 68 mpg, it was on michelin energy's, its now on continetal winters (same size) and fuel economy hasn't suffered. So I doubt it makes much difference...

What is the aim with the tyres width you want?

I have stock 15" for the summer (185 as Sharkrider said) and 14" for the winter with 165 section tyres to cut through the rain, snow etc...

To my mind wide section is more grip, so better, but on such a light car overly wide tyres are going to suffer when the weather turns bad compared to thinner ones.

The wider the section the longer it takes for water to be removed to the edges of the tread.

So a higher chance of aquaplaning, especially when you have a really light car that does not put much ground pressure on it's rubber.

Fitting 16" rims is going be be a notifiable modification to the insurance company.

If going that bit bigger on the rim and it's for fun use I'd also probably for for 185 or 195 section tyres.

If 60 ps can roll the 185, and fuel economy as mentioned above, then 75 ps on 195 not that extreme. More or less the same on Honda's forum --US-- sort of...Someone went from 165 to 175 lost about 5-7mpg, both were LRR tyres. I guess that's not significant on my list. There is pro and contra on both, narrower and wider tyres. Fact, i am not planning two sets, so wide 195mm keep in mind rain and snow maybe not the best. Narrow 175mm questionable stopping power and cornering stability. How much extra grip has an all-season 195mm compared to a summer only 175? Which is better in show? 195 all-season sure has more grip but the 175 summer can cut through better. 185 could be ideal a bit of everything, but difference in diameter is 1.03% compared to factory 185/55/15, if insurers happy with that maybe that is the answer :-).

The funny thing with the Citigo engines is that both the 60 and 75 feel almost exactly the same, they make the same power and torque up to around 5,000(ish)rpm with the 75 then delivering more by revving the nuts off it and taking it to the redline. (and beyond at peak power at 6,200rpm, but redline is 6k)

Changing from 185 tyres to 165 I've noticed no real difference in fuel economy. I'm not sure it effects the drag profile of the car that much and the gearing is pretty much the same.

I have to say I'd probably stick with 185 section tyres for all year round use, if you are only going to run one set. Even if you do decide to go up to 16" rims.

Personally (and this is only my opinion) I don't think I'd want to be on 195 tyres in the winter in such a light car if we start having ice and snow.

on 185/50/16's the 1.03% would not be a problem, most wheel/tyre places say up to 2.5-3% difference is ok.. on my vRS I've gone from 205/40/17 summers to 205/45/17 winters (for cost and availability reasons) and thats 3.36% difference, my insurance company said "as long as the size is skoda approved we are ok with it, no changes to premium" and as they were approved by, and fitted by, the techs at my skoda garage I'm happy, means my speedo now reads accurate instead of fast,and I have a bit more clearance for the snow ;)

I agree with the engine, we test drove the 75, and own the 60, and I cant tell the difference! I assume they are the same engine , but with a different map.....

consensus so far seems to be 185/50/16's ;) mid-range about £60 each. but I would assume it will be a case of notifying your insurer as the 16 inch wheel is not a skoda approved fit... shouldn't be too expensive though.

The change of wheels needs to be declared.

I don't mind to let them know, hope Insurance Company won't take it as modifications if it does cannot be to pricey.

A specialist insurer would add them free of charge as it's a very minor costmetic modification.

Done some useful research and found out that VW Up! offers 16" alloys, so i am pretty sure that Skoda will take the stress from added weight also. On tyre front, cheapest version coming out with 165mm on 14" --i said 175mm above--, it's definitely not the most rubber on the ground but seams Skoda feels it's 'safe' enough to offer. Based on this infos at this moment i am on 16" 6J semi black alloys with 175/50/16R Vredestein Hi-Trac 2. with option to go up 185/195 if i feel i need to. It's quite a weird mix, but gives the look, excellent wet and good dry traction, i'll make it through when it snows and i do believe when it's melting just as good as a cheap snow tyre based on wet test and review. This case rolling resistance and fuel consumption won't suffer from upsizing, so to sum. up ...i cannot have everything but more or less i get what i wanted :-)

Finally here is a very interesting test about upsizing:

Ordered Citigo S at the begining of December for my daughter but when we specced black alloys they were over £160 each so the dealer said it would be cheaper to buy non standard Skoda wheels.We want to run on 15" rims and 185 tyres- can anyone point me in the direction of a reputable wheel and tyre dealer who knows their stuff,I dont want to order rims that won't fit

The stupid thing is that these are available factory fit in Europe which would be much cheaper but they are on the great Skoda UK banned options list it seems.

I do wonder if this is because of VAG control. Perhaps with the upsurge of UK Skoda sales they do not want to introduce even more competition for their UP! models by allowing more 'upmarket/trendy' parts?

Just an FYI, The CityGo/UP/Mii all run old style VW patterns

57.1 CB

4x100 PCD

Any Vag Group wheel from before 1990 should fit the CityGo.

I do notice a lot of discussion has been had over the 175 / 185 / 195 tred which is best etc etc but you are forgetting some very important things:

What wheels are you looking at fitting?

the ET(offset) and Width of the wheel will impact drasticlly on which tyer you can use

If you use something with a High Possitive ET and a wide wheel and large tred pattern then you run the risk of rubbing the tyer against the suspenssion, something with a Very Low Negative ET and a wide whee/tyer setup you will end up with the tyer tread sticking outside the arch which is not legal.

What wheels are you looking at fitting?

I found rare 5x16" perfect for 175mm width tyres, --go big but stay light--. Off set is a confusing thing for me, there is a few choices i will double check it with the supplier to be spot on.

http://www.willtheyfit.com/

Use that mate, You can input the current specs of the wheels and then input the spec of the ones you are looking work the correct tyer size and also see how much more 'Tuck' or 'Poke' you will get with them.

:happy: Rare 16"???? share? :happy:

Interesting, so my old p-slots "should fit" retro look?

Pics if you do try.

Pics if you do try.

Will not be until March aslong as dealer confirms the deal at the end of the week.
