Many people are surprised to learn that you can change tire size on the same rim. It may not be something you want to do every day, but if you have a flat or need new tires and no other options, it is possible. If your vehicle has steel wheels, they probably won’t look exactly the way they did before once you’ve changed them out. But with aluminum alloy rims that are specifically made for changing tire sizes over time, this can be done without any trouble at all. Just take your old tires off of the old rims and put them back on when you get new ones.
If your car’s current set of wheels are steel, then there will likely be some damage like scratches or dents in them after a tire change. You may even have a hard time trying to get the new tires on them, as they might not fit correctly. Steel wheels are also much heavier compared to aluminum alloy wheels , which can make it tough for older people or those without a lot of strength in their arms and hands. So if you’ve been looking at getting a set of alloy rims for your car or other vehicle, now’s the time.
What to Consider before changing the size:
1) Keep the same rim type (bolt pattern/PCD):
Tire sizing is usually evenly divisible by the diameter of the rim. For example, a 16 inch wheel may be used for different sized tires ranging from 14 to 18 inches. However, this isn’t true if you go up or down even one size. Going up one size will require wheels with more backspacing than stock, while going down will require less backspacing than stock.
2) Keep the same number of lugs:
A machine called an impact wrench is used to install and remove lug nuts on cars. Some impact wrenches can tighten or loosen specific lug nut types (e.g., five-lug nuts). So if your old rims had five lugs, make sure that your new rims also have five lugs and that they’re the same size. Otherwise, you’ll need to get a different impact wrench.
3) Keep tires within load rating:
When tires are installed on rims, the air inside them provides support against the downward force of gravity on the wheel assembly (called load). When tires exceed their maximum load rating capacity, it’s possible for them to rip away from the rim during use, potentially causing an accident or injury. You can look up your tire’s load rating using its size and speed rating as search terms on our homepage; we’ll show you both maximum and minimum loads required for proper performance and handling. If your old tire was overloaded compared to what your new one is rated for, then its load will need to be reduced after you’ve put the new tire on.
4) Keep tires within speed rating:
Speed ratings are an indicator of how fast a tire can go before it reaches its optimal or minimum performance level. If you’re going up one size, then your new tire will likely have a higher speed rating than the old one–and vice versa if you’re going down. It’s best to not exceed either of these speeds, as this can create excess heat that may cause premature wear and damage.
5) Keep the tire’s construction the same:
Similar to load ratings, some tires are designed with specific levels of stress tolerance depending on their type. One example is all-season tires , which are capable of handling everything from mild snow to heavy rains without any trouble at all. If you change your tire size but keep the construction type, then it’ll be more suited for whatever weather or terrain you’re driving on. Trying to handle whatever comes your way with a different construction will cause your car to perform poorly and wear out faster than normal.
6) Plan for rim width changes:
Rim width can affect how far apart your tires sit from each other–otherwise known as track width . This affects how well they maintain traction when cornering and during other types of motion. Using a rim that’s too narrow will push your tires closer together, which may cause the wheels to rub against one another. A rim that’s too wide can cause a reduction in traction, potentially resulting in loss of control over the vehicle.
If all of these factors line up properly for a tire change, then you should be good to go! But first things first–you’ll need a set of alloy rims . Aluminum alloy wheels are great for this job because they’re lightweight and strong compared to steel rims. This makes them easier to handle when changing sizes, less likely to bend or warp when the job’s done, and even gives your car a little boost in fuel economy (although this last benefit isn’t much of a factor when it comes to one tire). If you’ve been putting off buying alloy rims for long enough, now might be the perfect time to change things up.
