Just wonder what tyre pressure will be economic one for Magna?

On user manual it recommend 29 psi for front tyres and 26 psi for rear tyres. But I feel a bit more fuel consumption.

Who can suggest economic tyre pressure on your gear? I tried 31 psi feel better than recommend one.

36 on all 4

yup

and factory fitted tyre width, wider = much high wind resistance.

33 to 36

Check the tyre for max pressure rating though. :)

i would say 36 in front beacuse of extra weight and 32 in rear
if the tyres in wearing in the center of the tyre theres too much if its wearing on the outsides theres not enough

hey guys my tire fitter guy recomends 36 on the front and 34 on the back being a front wheel drive car you should put more air in the front tires so they dont wear as fast. . . . .

he recons that tire pressure wont hurt . . . . . . . works for me!!!

:shock: that would surely blow all 4 of them where I live.
Its hell in here (gets to 50 C in the shade). The max I go is 30 - 32

errrrr just pump them up on when its hot and the tyres are warm, then goto 36psi.

at the moment your just balding your sidewalls and outer tread running 30psi.

I run 36psi all round never had any problems. Off course if you were going to do any circuit racing or drag racing you would have to lower the pressures to compensate for higher working temperature as compared to normal street driving. :D

For best economy with least rolling resistance, one'll want the tyres to remain as round as possible under load, hence max pressure. This is not practical for a number of reasons & mainly due to ride confort and cornering performance to a great extend.

Where factory settings are aimed for max comfort and safety, it is an arbitary choice for the owner to deviate from these settings with acceptable safety margin.

To achieve best fuel economy is to drive safely and conservatively.

i live halfway to hell in Karratha so i cop the 42 degree + days and my tyres are inflated to 36 front 34 rear, even with the huge temps of the road the rolling resistance is far less and i have never seen someone with tyres that have been over inflated their whole lives, so pump em up and enjoy some better economy
