I've had my Mito for ten months and only had to put air in the tyres three times. On every occassion the reading was only 0.1 of a bar under the recommended amount. Has anyone else experienced this?

well I don't check my tyres with a pressure guage but I've had it for 4 months and haven't topped it up since it was new. You would expect new road tyres to last a pretty long time before deflating enough to require a refill.
I have a feeling my tyres have deflated a little though, because it appears to be cornering slightly worse than I remember..

No point complaining about MPG if you aren't even going to bother checking your tyre pressures :rolleyes:

Agreed, so many factors that effect fuel economy aren't taken into account. But a lot of threads that come up complaining about it are from brand new cars, i.e. the tyres should be inflated properly. But maybe they are over-inflated?

WTH? I've never once complained about mpg :confused:

In fact, my motto is 'buying an Alfa Romeo for its fuel economy is like buying a porn film for its plot'

Lots of things could cause slight leaks (or major ones): bad or damaged valve, any notches, scratches or damage to the wheel, any knocks to the wheel (pot holes or something), or perished tyres, but as they are new, wouldn't expect that.

As the weather goes colder, tyre pressures decrease. A loss of 0.2bar in the autumn is normal - a similar rise is to be expected in the spring.

Correct tyre pressure is vital for tyre life and safety and should be checked on a regular basis with an accurate gauge. There is certainly no guarantee that a new car has the correct tyre pressures by the time you drive it away from the showroom.

By the time a tyre looks or feels under pressure then its most likely way off the correct pressure and an over inflated tyre is just as dangerous, the pressure gauges on garage forecourts are notoriously inaccurate :rolleyes:

First time I checked my tyres since ive had it from new (9 months) and all my tyres were at 15 when they should have been 30.. Whoops :lol:

Whoops indeed :tut: Check the sidewalls for wrinkles, cracks or a different texture of the rubber around the middle. At 15psi you could easily have damaged the sidewalls. If your mileage isn't too high you should be alright...

Although, thinking about it it's unlikely that all four would lose that much pressure over that time period (assuming they were correctly inflated when you bought the car).. Are you sure the pressure gauge you are using now is telling you the truth? Get/borrow another one or go to a garage and check them again.

Went to the Garage 2day, My Pressure was 33 was on the fronts and 30 on the back. 1st time i've checked since i got it. I've always thought that my mpg and Handling were way off seems i found the culprit. So i've put it 28 on the front and 32 on the back. So lets c if there's a difference. Wot does every1 else put in the tyres?

I hope that is a typo!!

They should be:
2.3 (33PSI) Bar Front
2.1 (30 PSI) Bar Rear

So they were correct before you changed them......!!

Cold pressures of 2.6 in the front, 2.4 in the back, seems to even out the handling a bit. The problem with our lovely tropical weather is that tires heat up fast when you're driving on the highway, so that 2.6 bar could get up to 2.8 or 2.9 bar. Feels like driving on bricks instead of rubber :)

As you will see when you read the owners manual, pressures are different depending on engine and tyre size.

Always pays to read the manual at least once!!
