What happens when wheel diameter is increased?
But it’s not all bad. Increasing wheel diameter normally means increasing its width as well, making the contact patch between tyre and road larger, hence increasing grip. On the contrary, the increase in grip for the larger, wider wheels will culminate in faster and more composed handling as stated above.
Should I increase wheel size?
While larger-diameter wheels and tires should improve handling and high-speed performance, lower-profile tires also tend to have a firmer ride and may be noisier than the smaller, standard rubber. Bigger wheels cost more money. The bigger you go, the more expensive the wheels and tires.
Is it OK to change the size of your tires?
When changing your tire size might be acceptable It’s possible to change the size of your tires without actually changing the diameter. One example is if you want larger rims – you can buy tires that compensate for the larger rims by reducing the “height” of the outer tire.
What happens to the tire when tyre diameter is increased?
As the sidewall size goes down, the weight of the tire stays the same or gets bigger. However, as a result of an increase in wheel diameter, this makes the weight distribution of the wheel+tire combo worse – the heaviest part (the tire) is now further away from the center of the wheel – refer to Part I for why that’s bad.
Why are smaller tires better for the car?
Cost: Tires with a smaller rim diameter tend to cost less. Comfort: Higher sidewalls mean the tire can flex more over uneven roads, reducing noise and harsh bumps. Fuel Economy: Lighter wheels provide better fuel economy because the car does not have to work so hard to reach and maintain speed.
How to calculate the rim diameter of a tire?
We will be using a P235/60R-15 tire as our example: 235 is the section width, 60 the aspect ratio, and 15 the required wheel rim diameter. Here is the basic formula:

How big of a tire do you need for rear suspension?
Nothing is modified for the rear suspension as a driver would just want to level the stance. With the newly leveled stance, you can typically increase the tire diameter by 1.0″ – 2.0″. Check with the leveling kit manufacturer for recommended tire diameter and needed wheel width and offset for proper fitment.
