Hello everyone,
Obviously a bigger tire looks better, but I read that putting bigger tires on a car can slow it down. Does anyone have any real life examples to prove the point either way?

 

Real world, it s about the extra weight (if any) as I assume your would be leaving the overall diameter the same. If you change the overall diameter then it will make a bigger difference.

 

 

When the article read "bigger tires" did it mean larger diameter or wider tread? Tires can have a huge impact on performance, but I'd need to read that article to see exactly what they are talking about.

 

Bigger tires and wheels could have an impact on 0-60 times in both ways.

Heavier tires (taller/wider) creates more rotating mass that is a drag on straight line performance. This is why many drag racers use small wheels with wide tires.

Wider tires (more surface area) though not necessarily taller can increase traction which generally would improve 0-60 times since it would improve your ability to launch - assuming you actually can benefit from the traction and don't add more weight. This is also why drag racers use wide tires.

For most street cars you are more likely to buy too much tire/wheel negatively impacting 0-60 rather than improving. The upgrade could also help with track times. So the big question is what is the main goal - looks, 0-60/qtr mile, or road course lap times? Then you can find tires accordingly. There isn't one that will do it all, but it's pretty safe to assume if you keep the weight minimal and by a quality wheel you can at least minimize negative impact in other areas. If you are looking for a "mix", then the best bet is to invest in the tire compound.
