Buying new tires for your vehicle could be a struggle. This is due to a lack of awareness and knowledge of this diverse domain. However, we have made things easier to understand as a newbie. This review will offer you an understanding of technical metrics that you must know.
We will dive deep into the basics of tire profile understanding. I will share tips and tricks to save yourself from getting looted in this diverse market. More about profile upgrades along with its credibility and expert opinions. Choosing the right brand for your vehicle and my thoughts on tire profile upgrades and buying guide.
Basic knowledge about tires:
Tires manufacturing date:
The manufacturing date has a high significance on the quality, comfort, and driving capability of the vehicle. Most of the tires come with a maximum lifespan or shelf life of 5 years. The manufacturing date is written visible on the sidewall of the tire. If the manufacturing date is just above 8 months or at max 1 year then avoid those tires.
Always go for the tires with fresh manufacturing. That will ensure drive quality and tire rubber life. Expired and older tires either start to deform or lose their performance element. Commonly the tires get hardened and reduce the grip over time due to expired tread compound.
Hardened tires ruin the drive quality and make your suspension work more often. On longer usage of expired tires, they might even burst due to the lost elasticity and quality. This might be surprising why you are getting tires for cheap when they are still wrapped as new. As the manufacturing date gets older the tire will start to lose its actual value.
Stay aware of the tempered manufacturing date:
There are a few things to check for the tempered manufacturing date.
- Opt for a well-known brand for quality. Buy tires directly from authorized dealerships or trusted sellers.
- Scan the QR code on tires so that you can run a legitimacy test if buying from a third-party vendor. It will demonstrate the actual brand, tread pattern, and manufacturing date of the tires.
- If that specific brand does not provide any QR code then there are still ways that you can check for the tempered manufacturing date.
- Check for the place where the manufacturing date is punched. Tempered date leaves signs of roughness or overwriting on the same manufacturing date.
- Check for overwriting or rubber residue which makes the date rough. It will leave finishing flaws.
- Inspect the inner part of the sidewall where the date is punched. Check for roughness on the tire pattern.
Choosing the right profile
Tires have a specific size, width, profile, speed rating, and load rating as well. These elements have an impact on driving quality and comfort. Fuel efficiency also varies on the tire profile and design pattern you have chosen for your vehicle.
The tire profile is written on the sidewall in a highlighted color or the color just the same as the rubber compound. The tire width is written in a specific format for every vehicle for universal understanding.
The tire profile is usually written like 205/55 R18 91V and this number is usually not understood by many. Any uncertain size, width, or quality has a direct impact on the quality of the drive.
1. Tire width:
205/55 R18 91V The (205) in the profile signifies the width of the tire. The more the number gets high the tire will get bulky or greater in width. Yet the width matters a lot when it comes to the road grip, ride quality, and fuel efficiency of the vehicle.
| Advantages | Disadvantages |
| More width means the more surface area of the tire would be in contact with the road. Tires will offer better traction. | Equipping your car with a greater tire width than the recommended size makes quite an impact on fuel efficiency. |
| Greater-width tires make them look aggressive, especially when you are preparing your car for drags and auto shows. | Due to greater tire width, the tire becomes a bit heavier than the stock ones. |
| If you didn’t go for the right tire width. You may scrape your tires with the inside of the fender walls causing rust to develop. |
Choosing the right tire width:
The user manual comes with a specified tire profile so you are not going to have to issue finding the right tire profile if you want to keep the tires stock.
However, upgrading your tire profile is made easy by online configurators. It can recommend an optimal tire width without causing any trouble. But taking an expert’s opinion is always a good option.
For better analysis, you may take other car owners’ experience for an up tire size. However, you should know that increasing your tire width will cause it to reduce fuel efficiency.
2. Tire profile or thickness of the tire:
Tire profile is the thickness of the side walls from the upper lip corner to the lower lip corner. The profile or thickness is written in the same pattern as 205/55 R18 91V. The (55) demonstrates the numbers for tire profile. Every car comes with a different tire profile depending on the type, weight, category, and size of the car.
| Advantages | Disadvantages |
| If you want your car to look good with big alloys. The low-profile tires will be preferable for tight fitment. Especially if you are a stance lover. | Low-profile tires create an impact on ride comfort and the longer life of the tires according to their usage. |
| High-performance cars use low-profile tires for less weight and better efficiency. It is due to their design and less weight. These little things create a great impact on the grip and performance of the vehicle. | Reduced profile will result in a bit of a hard-driving experience against impact absorption. It may give you some uncertain or increased vibrations in the cabin. |
| Subjecting a low-profile tire to abuse will reduce its life or completely damage it. | |
| It is quite often that you have to make your suspension work a bit earlier than usual due to the extra job the suspension has to do for absorbing all that energy. |
Choosing the right tire profile:
If you want to reduce the tire profile then wheel wells will have greater space left which won’t look good, especially if you won’t make it static. If you are going for a bigger alloy then it won’t have an issue till you are going for the right profile by an expert opinion.
3. Rim size or tire size:
Rim size or the tire size has the greatest impact on the performance. Due to a longer wheel spin radius and higher weight than the stock ones. The tire size is written as 205/55 R18 91V so the (R18) is the tire size. The R in the (R18) means the rim and (18) means to be its size in inches.
You cannot equip a tire which is 17 inches in size and the rim size is 18 inches. So, you must have to go for the same size as the alloy. Rim size also determines some metrics of the tire width and the tire profile or the thickness of the tire.
| Advantages | Disadvantages |
| Upgrading the rim size makes the car look good and fuller while making it aggressive at the same time. | Your car will have greater mass if you have upscaled your rim size by quite a difference. It will affect the economy significantly. |
| The stance community goes for bigger alloys for tight fittments. | Due to greater mass over the stock ones. The car will have a greater unsprung mass. Results in suspension to work much harder to absorb the vertical factor which will reduce the life of the suspension parts at a higher rate. |
| Upgrading tire size will increase traction. | It might increase the 0-60 figures due to increased weight. |
Choosing the right size:
Tire size has a direct impact on the other specs of the profile. If you do not have the right tire width or an optimal tire profile that sits with your rim and vehicle, it will make the car less reliable.
4. Tire maximum load capacity or load index:
The load capacity depends upon the usage and type of your vehicle. Load capacity is a unit that determines the maximum load capacity you can take at max without getting the tires malfunctioned. The right load index of the tire arises from vehicle type.
The load capacity unit is written as 205/55 R18 91V. The (91) signifies the load index. Actual load capacity can be found easily on the load index chart. If you are going to use your vehicle for commercial work or loading then go for a tire that is rated with a higher load index.
Shortcomings:
- Greater load capacity tires usually have higher weight than regular tires due to the extra material. Always go for the right load index when choosing tires.
- Going for a low-load index tire for a vehicle that is going to be used to load tons of weight will either blow it or shorten its lifespan.
Choosing the right load index:
Whenever choosing a new pair of tires either go for the one that is recommended by the manufacturer. Modifying load index is never suitable for regular vehicles. It is due to the vehicle’s weight and capacity to pull all that load.
5. Tire speed rating:
The tire speed rating will be written with the tire specs as 205/55 R18 91V. The (V) with (91) is the speed rating metric. The speed rating chart is available online or you can also ask for the chart from the dealers you are getting those tires from.
A greater alphabet will increase the maximum tire speed rating. If you achieve 200 km/h speed and the tires are only rated with a speed of 180 km/h then it can cause a huge problem.
This is because the tire at high speed generates high pressure and temperature inside. If they are not rated perfectly for the vehicle’s speed then either the tires won’t grip optimal or in the worst case they can burst.
