i have one question, would bigger tires (diameter) give me better economy on highways? and a decrease in city?

What size tyres do you have at the moment?

 

What makes a small difference is tyre width. So if you had 205/45R16 and changed to 185/65R14 you might get about 3% better fuel economy.

 

There are also differences in each tyre size, as some have less rolling resistance than others.

 

Do you get Euro labels in the Caribbean stuck on new tyres like in Europe?

i have 185/60 R14.

 

Nop, no Euro label, when selling cars here, fuel efficiency is ommited in listings, ads, commercial and even at the dealer, unless you specifically ask for that information, and most buyer don ask for it...  they dont care, they dont measure it, so you get an idea.

 

 

i was thinking about getting a 185/70 r14 but dont know how much will that impact the urban circulation.

Are you thinking in terms of lower engine rpm for a given road speed?

if it gets me better fuel mileage, yes.

165/70/R14 (on 5J wheels) is a standard size for Mk1 Fabia. That would have about the same rolling radius but be more than 10% narrower so might be worth trying if you can find some cheap tyres/rims in that size, for comparison. 

No rpm advantage, but that would only help on the highway anyway I think, once you run out of higher gears to choose.

Yes i got this car with those tyres and i will be needing new tires in 3 or 4 months and i am plplaning to put its original tires.

What size rims have you got?

 

The 165/70R14 probably came on 5Jx14 ET35 rims.

 

For steel rims, you can see this information stamped on the outside of the rim near the wheel bolts. The lettering is small, so you might need a magnifying glass to see clearly.

 

185/70R14 is a more expensive size than 185/60R14 or 185/65R14.

 

On 5J rims, changing from 165/70R14 to 175/65R14 is a popular choice. Like 165/70R14, 175/65R14 is one of the cheaper tyre sizes.

 

175/65R14 is also fitted to the Skoda Citigo as it's entry level tyre.

 

175/70R14 is the entry level size for the Fabia MK3, but tends to be more expensive than 165/70R14 and 175/65R14.

 

You may find the top gear too high using 185/70R14, which could increase fuel consumption.

 

Driving style is by far the biggest factor in reducing fuel consumption.

185/60R14 and 185/65R14 is ok for a 6J rim.

 

185/70R14 would be better fitted to a narrower 5J rim.

 

The latest VW Polo uses 185/70R14 on 5Jx14 ET38 rims, although that car's gearing is correct for this larger outside diameter.

which rim is mine?

It's cast into the back of the alloy rim.

 

It will be either 6Y0601025 7ZS or 6Y0601025E 7ZS

 

6Y0601025 is the 14" version.

 

6Y0601025E is the 15" version.

 

7ZS is the colour code, ie. chrome coloured metallic.

i uploaded a picture, i t think they are of magnesium, aluminium?

If you have 185/60R14 tyres, I think it must be the first one!

They are sand cast aluminium, like most alloy rims.

 

They are not magnesium. Magnesium would corrode (rust) easily, and are more suited to racing cars than road cars as they are not durable enough for road use.

 

Expensive cars like Ferraris and Porsches, will use forged aluminium which is stronger and lighter than sand cast aluminium but much more expensive.

i will doubble check that

Your suspension looks quite high. Does it have the +15mm off-road suspension option? This might be a standard option for cars sold in the Caribbean, due to poor roads.

Oem raised suspension? Wonder If I could find a set of those for my mk1.
