Simple tire question

[efedor]

I'm wondering, if you had a boxster with worn out tires and a boxster with brand new tires and they were both to drive off at 75 from a standstill, not a race, just driving, would the acceleration and/or speed maintainence be the same between both cars or would the car with the new tires beat it? and why? thanks in advance

I'm no scientist, but m money would be on the new tires.

Fewer heat cycles, to me means the compound on the new tires would have more grip.

Worn out tire means many of heat cycles and a hardened compound.

So what your saying is that since the compound is hardened it may allow the old tire to "slide" and create a lesser traction? so if thats the case, would that mean that I would get higher gas milage and faster acceleration? thanks

In theory I would think more grip would mean less energy wasted getting up to speed, so technically you might see better mileage with newer tires, but the difference would probably be minute and difficult to measure.

Where are you going with this little exercise?

I just put new tires on my 04 boxster and was wondering why I felt the car accelerate faster....was it the tires, my brain? so thats why I was wondering. Thanks for your input.

Efedor, it was your brain justifiying to your wallet why you have spent soooo much money on tires! Enjoy. :)
