Goodyear Efficient Grip on 1.6MultiJet? What pressures?

It should be an easy question shouldn't it....turn to the right page in the manual (page 193/194) and read from the table. EXCEPT:-


There appear to be THREE options I have found so far.


I will list them and the sources but the difference between the highest and lowest figures is a massive 27% difference in front tyre pressure being recommended, so something isnt right and I am guessing there must be a fair few owners running around with pressures which are incorrect as they or the dealer used the wrong figure, as the dealers seem confused as well.


I am using the figs below for my car the 1.6 Multijet station wagon, but if you have the Goodyear Efficient Grip tyres similar anomolies exist for the hatchback as well.

OPTION 1: - The owners manual says for the 1.6 Mjet station wagon with 205/55 R16 tyres, pressures are 2.5bar front and 2.3 rear. (Tyre brand unspecified).

OPTION 2: - My car is an 'Easy Plus' spec not an ECO. However the owners manual also says the 'ECO' model (same car/engine/weight and tyre size as mine) and with with Goodyear Efficient Grip Performance tyres (same as mine) still the same 205/55 R16 size the pressures are increased to 2.8 bar front and 2.5 bar rear. Which is quite a big increase just for a different tyre brand. But as my car is identical weight/power/configuration AND has these tyres fitted this seems the to be the most likely set of pressures to use.

OPTION 3:- The supplying Fiat main dealer advises me that it should be 32psi (2.21 bar front and rear). That is an absolutely massive 0.59 bar or 8.5 psi difference for the fronts v. what the manual says for a car with the Goodyear Tyres.

I was not comfortable with the dealers answer, so the question was put to another branch of the same dealer, and they were going to look into it, but never called back, so my guess is they were not clear either.


So my final attempt to get the right figure was to go to Fiat directly. One email and one phone call later and they have admitted they are confused as well and have gone away to investigate.


I dont have an answer just yet, but will post up again when Fiat give a definitive. If anyone has been through the hoops before it would be great to know what answer you were given, but 27% between the lowest and highest figures is a little errr... worrying, for such a simple question!!

Re: Goodyear Efficient Grip on 1.6MultiJet? What pressures?

I dont know if other models have the Goodyears fitted, but if you have a 1.6 diesel with Goodyears you might want to check you have 40.6 psi in the fronts and 36.2 psi in the rear.


I now have the answer from Fiat HQ, so to summarise:- the UK main dealer had it wrong (32psi F&R quoted), Fiat customer services acknowledged it was unclear (so couldn't answer my question), so it went to the Technical Dept at Fiat in Italy, and several emails were exchanged. VIN numbers were checked and photos of the tyre wall sent.


So the final answer I have received back:-


FRONT: 2.8 BAR (with “Empty and medium load”)
REAR: 2.5 BAR (with “Empty and medium load”)

In other words read from the heading in the manual for the 'eco' model, rather than standard model pressures. Above is correct if 205/55R16 91V or 91H Goodyear Efficient Grip Performance tyres are fitted. Pressures should be the same for hatch or station wagon when unladen (but differ when fully laden).



So yes, if you have those tyres, the fronts are indeed supposed to be pumped up all the way to 40.6 psi. Rather shockingly a full 8.6 psi higher than the main dealer quoted, so it was worth asking for clarification !!


It still seems unusually high to me, and they didn't explain why other tyre brands had much lower pressures recommended, but there you go... the figures have come straight from Fiat, so I hope it helps someone.


It isn't just me though !! It looks like it caught out some of the main dealers as well.

Re: Goodyear Efficient Grip on 1.6MultiJet? What pressures?

I've got Goodyear Efficient Grip tyres on my new Tipo. However, mine is a 1.4 with 15 inch wheels and interestingly, according to the manual, this is the only engine where there is no differentiation between tyre size, pressure and brand.

Just a thought, but I wonder whether the Goodyear Efficient Grip tyre is the preferred tyre for the Tipo and on the bigger / heavier engine models in the range the higher pressures are required to gain / achieve optimum efficiency maybe?
