Where do you find rim size?
Locate the stamped size on the back of the hub on the rim. This is the assigned measured size of the rim, and it is broken into three sizes: diameter, width and bolt pattern. For example, a 14 by 6 by 4.5 reading on the rim indicates that the diameter of the rim is 14 inches, and it will accommodate most 14-inch tires.
What does ST205 75R15 mean?
It means the section height of the tire is 75% of the 205 mm section width. … The 15 is the wheel diameter in inches and the C after the tire size will designate the load range. The load range C is a 6-ply rated tire. The maximum load rating on the load range C tire in the ST205/75D15 size is 1,820 lbs at 50 psi.

What is a 5 on 5 bolt pattern?
The 5×5 Bolt Pattern or Pitch Circle Diameter (PCD) is made up of the stud count (5) and the bolt circle measurement (5), the notional circle determined by the center position of the studs. The 5×5 bolt pattern is common to Buick, Cadillac, Chevrolet, Chrysler, Daewoo, Dodge and Fiat vehicles.
Is 10mm offset a big difference?
10mm isn’t a huge amount. On some cars it makes little difference. Tough you say. But if you want exact fit…see if the dealer still make it right.
How many inches is a Offset?
Offset is simply the distance from the hub mounting surface to the center of the wheel. In other words, Offset = Measured Backspace – Calculated Wheel Center Distance. In this example, we already know that our Measured Backspace = 5 3/16 inches. And we know that our Calculated Wheel Center Distance = 6 inches.
How do I identify my rims?
Inspect the rim of the wheel. The rim is the outer part of the wheel (not the center), and manufacturers like BBS often have their logo molded into the rim for identification. Also inspect the area around the lug holes where the wheel is fastened to the car. Often there will be a logo or company name there as well.

Can I put bigger wheels on my trailer?
You can add larger wheels and tires to a trailer as long as you have enough room for the larger size. … Larger tires will typically have a higher weight rating. Tires with a higher weight rating will not increase the load carrying capacity of the trailer, so you will still be limited to the weight capacity of the axle.
Can you run two different size tires on a trailer?
An important point of consideration is when using two different size tires, the load has to be no more than the capacity of the lowest rated tire. With this substantial difference with both weight capacities and inflation levels, the chances of inadvertently overloading on the smaller side tire is quite possible.
How do you measure tire sizes?
The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.
Which is better Load Range C or D?
The difference between an load range C and load range D tire in the same size is the capacity and psi rating. … The D rated tire has a higher capacity. For a ST175/80D13 like # AM1ST77, the capacity is 1,610 pounds at 65 psi. For a C load range in the same size, like # AM1ST76 , the capacity is 1,360 pounds at 50 psi.
What is the difference between a D15 and R15 tire?
The R15 is a Radial tire and the D15 is a Bias Ply tire. … These tires are usually a harder rubber and can carry more weight but not necessarily a smoother ride.
What does AD stand for on a trailer tire?
The D indicates that the tire is a diagonal bias ply construction and the R indicates that the tire is a radial tire construction. Beyond the size and type, there are load ranges for tires. Most trailer tires are load range B, C or D.

How do you measure the bolt pattern on a trailer?
