Goddard Tires 235/60R18 107H XL: What Do the Numbers Mean and Will They Fit Your Car?
When buying new tires, a code like 235/60R18 107H XL can look like a random string of numbers and letters. In reality, it tells you a lot about the tire: its width, its sidewall height, the correct rim size, the load it can carry, and even its speed rating.
One option available in Kuwait is the Goddard TRANSFORCE 568 in size 235/60R18 107H XL, listed by B2B Auto under SUV tires, with a load index of 107, equivalent to 975 kg per tire. It is also not a run-flat tire.
What does 235/60R18 mean?
Let's break the code down into its parts to make it simpler:
235: The nominal tire width from one side to the other, measured at 235 mm.
60: The aspect ratio — the sidewall height as a percentage of the tire's width. This means the sidewall height equals 60% of 235 mm, or roughly 141 mm.
R: Indicates that the tire is built with a radial construction, the standard structure used in modern car tires.
18: The rim diameter the tire fits, which is 18 inches.
One important point to keep in mind: having an 18-inch rim on your car doesn't automatically mean any R18 tire will fit it. The width, aspect ratio, load index, and speed rating must also match the specifications set by your car's manufacturer.
What does the number 107 mean?
The number 107 is the Load Index.
For this Goddard tire size, a load index of 107 corresponds to a maximum capacity of 975 kg per tire when used under the tire's specified conditions and pressure.
However, this doesn't mean the vehicle's allowed weight is simply calculated by multiplying 975 by four and using that as a loading baseline. Tire selection should be based on the load index recommended by the car manufacturer and the requirements of each axle.
So when replacing a tire, never choose one with a load index lower than what your car requires.
And what does the letter H mean?
The letter H is the Speed Rating, indicating that the tire is rated for speeds up to about 210 km/h under the tire's specified operating and load conditions.
This number, of course, doesn't mean you should drive at that speed — actual driving speed should always comply with road limits, traffic laws, and driving conditions.
More importantly, when buying a replacement tire, make sure the speed rating matches or meets the minimum required by your car's manufacturer.
What does XL mean?
The letters XL stand for Extra Load, meaning the tire has a reinforced structure that allows it to handle higher load and operating pressure than the standard tire of the same size.
This is why XL tires are common in many SUVs, crossovers, and heavier vehicles. Note that having XL doesn't mean the tire is run-flat — and in fact, Goddard's specifications for the 235/60R18 on B2B specifically confirm that it is XL but not run-flat.
Is the Goddard 235/60R18 107H XL tire right for your car?
It could be a good fit if your car manufacturer specifies 235/60R18, and if the load index of 107 and speed rating of H meet the requirements specified for your vehicle.
Simply having an SUV or an 18-inch rim is not enough on its own.
Before buying, check the label usually found on the driver's door frame or your owner's manual, and compare the size, load index, and speed rating against the required specifications. Tire manufacturers recommend always referring to the car manufacturer's specifications when choosing the correct size and pressure.
Is this size suitable for daily driving in Kuwait?
If this is the size approved for your car, its specifications place it among the sizes commonly used in many SUV and crossover applications. B2B also classifies the Goddard TRANSFORCE 568 in this size under the SUV category and describes it as a tire suited for daily driving and long road trips in Kuwait.
Given Kuwait's heat, choosing the right tire isn't enough on its own — tire pressure matters too. Check pressure while the tires are cold, and stick to the value specified by your car's manufacturer, not the maximum pressure printed on the tire's sidewall. High temperatures and driving heat both raise the internal air pressure of the tire.
Summary
The Goddard 235/60R18 107H XL size designation means a tire with a width of 235 mm, a sidewall aspect ratio of 60%, fitted to an 18-inch rim, with a load index of 107 (= 975 kg per tire), a speed rating of H (up to about 210 km/h), and a reinforced XL (Extra Load) construction.
But the more important question isn't whether the tire is generally good for SUVs — it's: does this specification match what your car's manufacturer recommends?
If the 235/60R18 size along with the load index and speed rating suit your vehicle, then the Goddard TRANSFORCE 568 is worth including among the options you compare when buying new tires in Kuwait.
