Tires are a lot more than just four pieces of rubber. They are tasked with transferring the power from the car to the road and supporting the weight of the car, yourself, your passengers, your dog, and your luggage. As such, you need to pay a great deal of attention while shopping for a new set of tires, and knowing what comes with a set of tires and what does not is also something you ought to be aware of.
Do Tires Come With Rims?
While buying a set of tires you are only buying the rubber which means that rims do not usually come included with the package. If you don’t own an adequate set of rims you will have to purchase them separately. However, some wheel packages do include both the rims and the tires, so be sure to investigate thoroughly before you decide to spend your money.
Which Parts Make Up A Wheel?
A wheel is essentially made up out of the tire, the rim, and the hub which is being held in place by a set of lug nuts. The rim is designed to keep the tire in place in order for the tire to do its job while the hub is designed to house the bearings which tie the wheel to the axle. A well-manufactured hub consists out of tiny steel balls which transfer power with almost no friction.
Some wheels also come with hubcaps which are designed for aesthetic purposes. All of these components serve a vital role when it comes to on-road safety and thus need to be adjusted according to the manufacturer’s recommendations.
How To Buy A Set Of New Tires?
Before you go ahead and buy a new set of tires you need to make sure you are buying the right set. As such, you need to match the dimensions listed on your existing tires with the newer set. You can also check your owner’s manual for tire dimensions information or contact your dealer directly and ask for further instructions.
You should always replace all four tires at the same time in order to balance out tire wear across all four tires. This is especially the case if you own an all-wheel-drive car. You should also buy a set of tires with a specific speed rating depending on what type of car you own. If you are not willing to replace all four wheels at the same, be sure to at least replace the front two tires or the rear two tires at the same time.
How To Buy A Set Of New Rims?
No matter if you are buying a new set of rims for aesthetic purposes or you simply need four rims for a set of tires, you need to make sure you buy the right set. Many different factors influence how expensive or cheap a set of rims might be such as if they are forged or cast, are they a single-piece rim or a two or even three-piece rim, are they custom made, or off the shelf, or how big and substantial they are.
Factors To Consider When Buying A New Set Of Rims?
If you’ve already purchased your set of tires and you need to buy a set of rims separately, make sure to consider these factors before you buy:
- Wheel Diameter
- Wheel Width
- Bolt Pattern
- Load Rating
- Center Bore
The diameter of the wheel is essentially the size of the wheel which is being measured in inches. If your tires are made for 17” inch rims, you will have to look for a 17” inch rim. There isn’t much you can do if your wheel and tire diameters are not the same, so be sure to match them accordingly. If you own a performance car, you are likely going to need wider wheels in order to house low-profile tires.
The wheel width is the distance between the wheel bead seat faces and the wheel and tire width don’t have to match 100%. However, don’t attempt to mount a tire that is more than 20 millimeters wider than the wheel itself. It’s always best to match your wheel dimensions with your tire dimensions as closely as possible in order not to affect your car’s transmission and many other components.
Wheel offset is the distance between the wheel centerline and where the wheel is mounted onto the axle. As such, a wheel can have either a neutral, a positive or a negative offset depending on the distance between these two so make sure to buy a set of rims with the same offset as your existing set.
Your car’s bolt pattern and the bolt pattern of your new set of rims need to match precisely for your new set of rims to successfully mount onto your car. You can invest in a set of wheel adapters but these can only help if the differences are minimal. Either way, it’s best to match the bolt pattern completely in order not to risk any potential issues that might arise from faulty adapters or bad installation.
Load rating refers to how much weight a specific set of rims can endure. This is not all that relevant for passengers vehicles and is mostly associated either with heavy-duty trucks or commercial vehicles.
The center bore is the hole situated in the middle of a rim that needs to precisely match the car’s wheel mounting surface. As such, be sure to match these two whenever you invest in a set of new rims. If the center bore is larger than the wheel, there really is nothing you can do about it.
As previously stated, a tire set does not usually come included with a set of rims. However, it all depends on what you are buying as some packages do include both rims and tires. Some packages will also include special lug nuts and hub caps while others will only include installation, tire mounting, balancing, and old tire disposal.
Either way, you need to make sure you buy a matching set according to all of the parameters listed in this article. If you are having trouble deciding which type of rims or tires to go for, it’s best to contact your local dealer or your local tire shop.
