Guys,

How does changing to a bigger tire translate to power and speed?

thanks,

city

It doesn't.

Bigger tire = more unsprung weight
Bigger tire = more revolution per turn for the crank/axle
Bigger tire = more contact patch resulting to more resistance in initial roll.

All points to No, it doesn't.

What it does is increase the contact patch of the tire to the road resulting to better grip and handling.

perfect answer!

does that mean slower acceleration and speeds too?? Read also that wider tires means less grip on wet roads? thanks for any info.

having bigger tires (i.e. as in wider) is likened to having a bigger footprint thus more friction against the road which means better grip. this translates to better control but the trade off is usually worse mileage as the engine has to work more in order to off-set the increased friction between the tire & the road. on the other hand, having bigger tires (i.e. as in thicker) is likened to having more cushion between the cars body & the road translating to a more supple ride, granting a normal tire psi. the trade off however, is also like having a wider tire.

Bigger tires (in diameter) can help your fuel economy a bit i heard.

I think for powerful cars it can help in acceleration(less wheel spin) and braking because of the larger footprint/contact patch.

For weaker cars, it can just make the car less aerodynamic, slightly slower and probably slightly less fuel efficient.

Well, for more powerful cars, their wide tires are pretty much "stock" for them, kung baga, minimum requirement to get the power transferred as opposed to aftermarket upgrades wherein the stock 195 to 215 tires are more than sufficient.
