I read up some articles on tire.
The finding is counterintuitive, therefore would like to share.
Bigger Tire does not improve your vehicle traction. (175/185/195 all the same, given the same load and pressure)
Bigger Tire increases the risk of Hydroplaning in wet weather. Meaning your tire float more easily on wet surfaces.
Bigger Tire gives lousy ride.
Bigger Tire increases fuel consumption.
Any Egineers out there to counter the above points?
