Advice needed on + and - of going from 17" to 16" wheels
That's why I said this... "Although 205/70R15 is a non-standard size on the Yeti, many owners do fit non-standard tyre sizes in the UK." 15" wheels have never been approved by Skoda for fitment to a Kamiq. However, skoda-parts.com are listing 15" wheels to fit them. https://www.skoda-parts.com/spare-part/2q0601027t03c-steel-wheel-disc-skoda-38412.html

Advice needed on + and - of going from 17" to 16" wheels
That's why I posted the load index of all three tyre sizes. The 205/70R15 tyre actually slightly exceeds the load carrying capacity of the 215/60R16 and 225/50R17 sizes. In many difficult winter conditions the narrower 205/70 size would outperform the boy racer 225/50 size especially if fitted with good 3PMSF tyres. Even on the Skoda Kodiaq RS with 20" wheels, you will soon find the limit of the car's handling when undertaking the moose test...

Skoda specified 16" and 17" wheels because of fashion, not safety. Cars like the Skoda Citigo with skinny 165/70R14 tyres have the lowest insurance premiums because low performance equals low risk.

These three tyre sizes all have similar outside diameters and similar load indexes. They are all interchangeable. 205/70R15 (710kg load index at 3Bar/44psi) 215/60R16 (690kg load index at 3Bar/44psi) 225/50R17 (670kg load index at 3Bar/44psi) The Skoda Yeti often has 312mm diameter front discs which means that you need at least 16" rims to clear the front brake calipers. However, on the lower powered models 288mm diameter front discs are fitted. This means that 15" rims will clear the front brake calipers. 205/70R15 tyres are more comfortable, more mpg, and less decibels.

All Weather tyres and Summer tyres
Asymmetric tyres are not directional. Once fitted correctly to the rim, asymmetric tyres can be fitted to the vehicle in any position...left or right, front or back.

7Jx16 ET45 5/112 57.1 is the standard rim size for the Yeti with 215/60R16 tyres ET45 means that the offset is 45mm. ET stands for Einpresstiefe which is a German word. In English, Einpresstiefe means offset. 5/112 means 5 bolt holes with a BCD (Bolt Circle Diameter) of 112mm. 57.1 means the centre bore is 57.1mm. Alcar 9257 are aftermarket steel rims that match the original Skoda steel rims. https://www.oponeo.co.uk/steel-wheel/alcar-kfz-9257#21246586 https://www.autodoc.co.uk/alcar/14750851 https://www.mytyres.co.uk/cgi-bin/skw.pl?dsco=110&s_p=Steel-Rims&sowigan=felgen&Hersteller=Skoda&PKWtyp=YETI+2.0+TDI&PKWtypgenau=%3A533741%3A%3A1968%3A81%3A200909%3A++++++%3A57.00%3A112.00%3A5%3A5L++++++++++++++++++%3A%3AO%3AE11*2007%2F46*0010*.++&Show+types=Show+types oponeo is a useful site to find the Alcar model number. autodoc are usually cheaper for steel rims than oponeo. mytyres also sell Alcar steel rims, but you have to search for them my entering a car model that they fit rather than just entering the Alcar model number. As well as 7Jx16 ET45 rims, 6Jx16 ET50 steel rims were also available for winter tyres in size 205/55R16. http://www.oemepc.com/skoda/part_single/catalog/sk/markt/CZ/modell/YET/year/2015/drive_standart/779/hg_ug/601/subcategory/601010/part_id/2543667/lang/e 7J rims are quite wide for a 215/60 tyre size. 6.5J is more normal for this tyre size. Alcar 8226 7Jx16 ET41 5/112 57.1 from the Skoda Superb MK3 which also uses the same 215/60R16 tyre size as the Yeti https://www.autodoc.co.uk/alcar/14750743

All Weather tyres and Summer tyres
This is the latest all-season tyre review. It was posted just two days ago on 27/9/20. Goodyear G3 came 1st out of 32 all-season tyres on test. Vredestein Quatrac came 2nd. The Vredestein Quatrac is new and replaces the Quatrac 5. https://www.tyrereviews.co.uk/Article/2020-Auto-Bild-All-Season-Tyre-Test.htm

Citigo Tyre Time
This link on national tyres is the Continental AllSeasonContact in size 185/55R15 86H. It's a good all-season tyre. Not the same as the TS860 which Continental classify as a winter tyre. Both tyres do well in tyre reviews. https://www.national.co.uk/tyres-search?width=185&profile=55&diameter=15&rating=H~&loadindex=&pattern=allseasoncontact However, Vredestein has just brought out a new all-season tyre called Quatrac. It replaces the Quatrac 5. Some sizes are being released now, other sizes won't be available until 2021. It came 2nd out of 32 all-season tyres in this month's autobild all-season tyre review. Goodyear G3 came in 1st place. https://www.autodoc.co.uk/tyres/vredestein-8714692358241-ap18555015hqt6a00 autobild September 2020 all-season tyre review https://www.tyrereviews.co.uk/Article/2020-Auto-Bild-All-Season-Tyre-Test.htm

Upgrading 165/70R14 Tyres
Has anyone fitted wider tyres to their 5Jx14 rims? Vredestein Quatrac 5 all-season tyres are available in 195/60R14 86H. Same outside diameter as the 165/70R14 size. Hankook Energy Eco 2 K435 summer tyres, Kumho i*cept RS (W442) winter tyres, Kumho EcoWing ES01 KH27 summer tyres, Toyo Proxes CF2 summer tyres, are also listed on mytyres amongst many others. You may be wondering if 195/60 fits on a 5.0" wide rim? Well, 185/70 is a recommended size for a 4.5" wide rim and 205/50 is a recommended size for a 5.5" wide rim, so 195/60 should fit a 5.0" wide rim because 195/60 is in the middle of 185/70 and 205/50 and 5.0" is in the middle of 4.5" and 5.5". Here's a chart: 185/70 4.5" rim (Recommended size) 195/60 5.0" rim (Should fit) 205/50 5.5" rim (Recommended size) Another way of looking at it, is that both 185/50 and 205/70 is a recommended size for a 5.0" rim and 195/60 is in the middle of 185/50 and 205/70 so should also fit. Here's another chart: 185/50 5.0" wide rim (Recommended size) 195/60 5.0" wide rim (Should fit) 205/70 5.0" wide rim (Recommended size) The load index for a 165/70R14 tyre is 81 (462kg), whereas the load index for a 195/60R14 tyre is 86 (530kg), so you can lower your tyre pressures by about 5psi when replacing 165/70R14 tyres with 195/60R14 tyres... or more precisely multiply the fraction 462/530 by the tyre pressures that you use for your 165/70R14 tyres. This of course assumes that your tyre pressure for your 165/70R14 tyres are correct. Always seek expert help if in doubt.
