If you go from the stock tires to a 245/45/R16 tire in the rear, how much faster (if any) will our 60 foot times be? Please help thanks

 

same as stock.


not to mention this is totally dependent on driver anyways.

 

The smaller the diameter of the complete wheel, the quicker the acceleration but less top speed!? Is this correct? So a 14" wheel will make the car accelerate more quickly then the same car with for example 20" wheels...

 

yeah but a 245/45/16 is barely any smaller than stock.

 

Correct me if I'm wrong, but the stock 225 SO2's actually have a 245-size contact patch, so basically they are 245's. This is why people usually replace them with 245-sized tires when going with a different model.

 

Going to a 14" wheel is kind of like adding gears, except you also benefit from having less rotational mass.

 

Wheel diameter isn't what changes gearing. It's the diameter of the tire you put on that wheel.

EG. If you take a 16" wheel with the stock 225/50/16 tire on it and compare that to an 18" wheel with a 225/35/18 tire on it. The 18" setup will have better gearing for acceleration.

To answer the original question ........................ you won't accelerate any quicker. A 225/50/16 tire is almost the same diameter as a 245/45/16 tire. If you could get a 245/35/16 tire, then you would have an advantage, but your car would look really stupid.

 

I think he was talking about traction and 60' times, not acceleration. However, as stated above, the OEM 225's have the same contact width as non OEM 245's...so it will be about the same. Now, if you get some 245 drag radials, your 60' will go down considerably...if you can drive.

 

I did mean traction but thanks for all the info. I didn't know the stocks were same width as 245 aftermarkets.
