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.

195 wide tyres want a wider rim than 5 inch.

195 60 14 is a rare size so will be more expensive than other sizes.

 

Equivalency table

Rim width	Minimum tyre width	Ideal tyre width	Maximum tyre width
5,0 Inches	155 mm	165 or 175 mm	185 mm
5,5 Inches	165 mm	175 or 185 mm	195 mm
6,0 Inches	175 mm	185 or 195 mm	205 mm
6,5 Inches	185 mm	195 or 205 mm	215 mm
7,0 Inches	195 mm	205 or 215 mm	225 mm

 

On the cars I have:-

175 on 5 inch rims

185 on 6 inch rims

 

From 165 70 14 you could fit 175 65 14 or

Change the rims and tyres to 185 55 15.

 

Do not reduce the tyre pressure for a wider tyre.

Your chart is wrong as it doesn't take the aspect ratio into account when determining the minimum rim width needed for a particular tyre size.

 

Take for example a 205 tyre. The minimum rim width for a 205 tyre is between 5" and 7" depending what the aspect ratio is. Your chart says that a 205 tyre has a minimum rim width of 6". There is no 205 tyre that has a minimum rim width of 6". It's either 5", 5.5", 6.5", or 7", depending what the aspect ratio is.

 

Minimum rim width for 205/70 tyre is 5".

Minimum rim width for 205/65 tyre us 5.5"

Minimum rim width for 205/60 tyre is 5.5"

Minimum rim width for 205/55 tyre is 5.5"

Minimum rim width for 205/50 tyre is 5.5"

Minimum rim width for 205/45 tyre is 6.5"

Minimum rim width for 205/40 tyre is 7"

 

Same principal applies to all the other tyre widths.

 

Notice that the minimum rim width increases as the aspect ratio decreases, and vice versa.

 

ETRTO (European Tyre and Rim Technical Organisation) are the industry body that sets approved rim widths for car tyres.

Not sure what problem this would solve on a modest Citigo - often, wider tyres can reduce wet grip, and lower section tyres will harden ride.

 

Mine came new with 185/50s on 16" rims fitted, but if I'd had a choice, I'd have got something more compliant, but at least the handling is sharp as there is very little lateral 'give'.

 

That aside, unless you want to spend money to upgrade wheels, you may find that a really well-rated tyre of a good brand in your current width,  may well offer better characteristics (depending on what you wanted) than a 'bigger' but less developed tyre, tech-wise.....

It's not my chart.

Although it's often said that narrower tyres are better for wet grip than wider sizes, this doesn't apply all the way down to the narrowest tyres possible. With Skoda Citigo size tyres, I doubt even 185s are wide enough to start getting reduced wet grip. I think 175/65R14 would give more wet grip than 165/70R14. However, so much depends on the make and model of tyre. For Octavia tyre sizes such as 195/65R15 and 205/55R16, the 195 width may offer better wet stopping distances than the 205 width, but again so much depends on the make and model of tyre.

 

I would rather have 14" or 15" rims on a Citigo than 16". Although 16" rims give you sharper handling, the increase in comfort from 14" and 15" tyres would be a bigger benefit. Plus 185/50R16 tyres are far more expensive than 14" and 15" tyres. With such small sidewalls on the 16" tyres, there's also a bigger risk of damaging your rims when going over potholes.

ETRTO group 50 to 65 aspect ratios together when they do their rim width recommendations.

 

This means that the minimum rim width recommendations that ETRTO gives for 50 aspect ratio tyres are always correct, but that the minimum rim width recommendations that ETRTO gives for 55, 60, and 65 aspect ratios are not always correct.

 

For example, ETRTO recommends that a 195/60 tyre can be fitted to a minimum rim width of 5.5". However, because ETRTO recommends a minimum rim width of 4.5" for a 185/70 tyre and a minimum rim width of 5.5" for a 205/50 tyre it's easy to see that a 195/60 tyre will fit a 5" rim. Another way of looking at it, is that ETRTO recommends a minimum rim width of 5" for both a 185/50 tyre and a 205/70 tyre. So again, it's easy to see that a 195/60 tyre will also fit a 5" width rim.

 

If you don't fancy fitting a 195/60R14 tyre to a 5" wide rim because ETRTO doesn't recommend it, then 205/50R15 can be fitted to a 5.5Jx15 rim as ETRTO does recommend that fitment. I've done the maths, and 195/60 is actually a better fit on a 5" wide rim than 205/50 is on a 5.5" wide rim. ETRTO are based in Belgium and are one of these flawed European organisations. It's a good job we are leaving the EU.

 

Other discrepancies that I have found in ETRTO recommendations, are that 175/60 comfortably fits a 4.5" wide rim and 155/60 comfortably fits a 4" wide rim even though ETRTO recommends minimum rim widths of 5" and 4.5" respectively for these tyre sizes.

How many tyres do they sell?

 

Thanks AG Falco

ETRTO don't sell tyres. Here's a link to their website.

 

https://www.etrto.org/Home

 

There's not much technical information on their website. It appears they're into some kind of money making scam, as they sell technical manuals for over Euros 150 each. Fortunately for us, their recommended rim sizes are available for free elsewhere on the internet. Maybe some of the money the UK has been sending to Brussels each year for membership of the EU has been going to them to prop them up.

ETRTO is a trade body funded by its members, i.e. tyre manufacturers. This does not however, mean it is "anti-curved bananas" or any other preferred conspiracy theory
