used to have 175/70/13 on front, now i got 2 part worn 165/70/13s on the front...

what does 165 mean? cuz the steering seems heavier... good grip tho :D

165 is the width

ie smaller than u had on there

must b a better tyre as they are slimmer than what u had previously

what r the tyre pressures like as that could be the reason for heavy steering...... should b lighter with narrower tyres

You would think that wouldn't you, I mean about the narrower tyres thing. Usual the converse is true.

Up a width usually lightens the wheel in my experience, obviously going from a 5 inch wide 13 to a 10 inch wide 18 theres gonna be a lot more friction.

Width/profile/size indeed.

165 is the width in mm,

the 70 is the aspect ratio, 70% of the 165,

13 is the wheel size.

You'll need higher tyre pressure with the smaller tyres - smaller area supporting the same weight.

e.g

195-60-14

195 is the width in mm, 60 is the profile as percentage of the tyre width, in this case making 117mm, 14 is rim size in inches.
