maybe the VTEC has a bigg speedo error.35k on other cars means 47k on a vtec.
Yeah right!!! You mean so say that when my speedo is showing 100kmph i'm actually doing 76kmph?

When i did the Hubli-Ankola last week, my trip meter read 135.6 at the Ankola junction. The actual distance between Hubli and Ankola is 135kms. A diff of just 600 meters. That is as accurate as it gets dude. An error of 0.44% to be precise.

hey shan,

not kidding this time.

does your speedo still show the same reading even after changing the tires.

?????
i think its been more than a week since you changed your tires to 195/60r14
this tire size already has a diff of 1.11% over ur original circumference.
so the actual 135 kms of the Ankola road will show 136.8 km on ur speedo if its right.

but since its showing 135.6 instead of 136.8 means it already has an error .
so with ur stock tires the error will be more

Even though Shantanus tyres may have "lasted" until 45000 + kms, they would have lost their margin of "safe usability" by 30000 kms odd, for sure. Using tyres beyond the age where they deliver optimal performance is not recommended at all.

We change the tires in our OHC by around 30k max. The driver and my dad hardly accelrate hard, they dont go beyond 70kmph in it. but still since they travel on the highways often i get the tires changed at around 30k kms. Better to change it at that time bcas tires older than 30-35k (bridgestones atleast) have a serious tendency to aquaplane. I have experienced it on the highway on a accent.

BTW the new pirellis on it are absolutely rocking. its that energy series i think. have not checked the FE in it. but the ride is very good now. handling even more so. a perfect balance i would say. but they are very very sensitive and have to be balanced/wheel alignment done strictly every 5k or so i was told.

Dude, simple mathematics. My new tyres are bigger by 1.11%. So, it is bound to show more than the old tyres at any given point. I'f my car does 135.6 (over a 135km run) with a tyre circumference of 72.88 inches. A tyre with a circumference of 72.08 inches should read 134.11 kms.

And don't forget that the distance between your wheel hub and the road is the actual radius of the wheel and that can vary with increased or decreased tyre pressure.

It is practically not possible to get a therotical result. There are too many factors that come into the picture when you do it practically.
