If you want to change the size of your car's wheels, there are some good things and some bad things about doing it, also you can find more interesting information on zero60times.com. When you switch to a bigger wheel size (like from 17 inches to 18 inches), you need new tires that are the same size.
However, those tires need to be thinner so they can fit under the car without hitting things when you go over bumps or potholes. This makes the suspension work harder every time it goes up and down. If the wheel size goes up by one inch, then the tire height should go down by one inch as well, so that the overall diameter stays the same.
If you have the original stock tire size of 215/65R17 and you buy 18-inch wheels, the right tire size for the larger rims might be 225/55R18. This is because the larger-diameter wheel size will make the tires look wider (225 millimeters instead of 215), and also because a lower profile (55 instead of 65) will give your car a more stylish look.
If you change your wheel size, but not the tire size, then there will be a difference in speed. Your speedometer will read different things. You could get damage to the tires or even your car.
Make sure that you combine wheel and tire sizes so that there is no difference in speed like before. This way, the risk of damage is lower. It may cost more money but it can save you from lots of problems.
Some people think that getting larger diameter wheels and tires for their car will improve the car's handling and speed. But sometimes this can come at a cost. Larger profile tires can be harder to ride on and make more noise than smaller tires. They can also weigh more, which might offset any performance benefits you were hoping to get. Another thing to consider is the size of the wheel.
A steel wheel weighs more than an aluminum alloy wheel, but an expensive, lightweight aluminum alloy wheel might be a good idea if you want to upgrade your car's size.
Bigger wheels cost more money. The bigger you go, the more expensive they get. If you buy larger wheels as part of an option package on a new car, or if it comes with them when you get a higher trim level, the initial cost may not be that high. But when it comes to replacing your wheel or tire the extra expense can be substantial.
