    @Krishna :Sorry for the wrong calculations and misleading you, effect of parallel processing :A
    @redtux : Break failure? How? Is it related to the ABS?

    Re: Tires

    The theory is that while making these changes, you keep the overall tire diameter within 3% of the original equipment tires. This is important because larger variances can cause problems with transmission shift points which can decrease fuel mileage. It can also confuse braking system computers which can even lead to brake failure.

    Here's the rule of thumb for "plus sizing":

    Plus 1:
    Increase section width by 10mm
    Decrease aspect ratio by 10 points
    Increase rim diameter by 1 inch

    Plus 2:
    Increase section width by 20mm
    Decrease aspect ratio by 20 points
    Increase rim diameter by 2 inches.

    This is not exact, but it will usually get you in the right ballpark.

    Got the new tires and alloys installed two days back. And just back from Chennai. It was a great trip. Started from Trivandrum went to Kochi, from there Palakkad, Salem and Chennai. The tires immediately showed off there grip level. ::T You can hurdle the car into corners with more speed, and great confidence :dance . Breaking distance seems to be reduced. For the Chennai trip from here to Chennai via Salem the MID showed an average of 19.3 km/l. ::D I think that s respectable economy. On the way back through the L&T road, we just blasted!! High speed corners taking at speeds around 120 to 140. :twisted: And the speedo showed 180km/hr.( give or take a few km/hr). Mileage dropped to 18.4km/l. Only thing bothering was like Pran said on wet surfaces, the grip levels are a bit low. ABS inter veins everytime i slam on the brake. :A Ride comfort is good and road noise levels are low. Here are some pics of alloys and tires.. some are shaken excuse ..i was shivering. ::D

    Jiji, really nice alloys. Not too flashy, not too dull. If i am correct there are 5 black spokes, rt? If so, the alloys look like a 5 silver-spoke one but better load distribution with the 10 spokes. Good choice man!

    1 doubt , while changing my punctured tire i noticed there are two pins on the hub and holes for it on the steel wheel.
    Do the alloys have provision for these pins ?
    i know that fiat alloys have it.
