What number is 12.5 wide tires?
Tire Width - "1250"
Standard tire width is indicated in inches with the decimal point removed. Therefore, in this example, the number 1250 indicates that this tire is 12.5" wide.
A 12.50-inch wide LT tire, for example, might show a range of approved rim widths from 8.5-11 inches.
The number “225” stands for the width of the tire in millimeters – so in this case the tire is 22.5 cm wide. The “45” that follows is the aspect ratio - the height of the tire sidewall as a percentage of its width.
For example a 275/35 R19 tire size, it means that the width of the tire is 275mm (~ 10.8 inch) wide. The picture below shows an illustration of the 275mm length tire width. An illustration of what 275 means in a tire size designation.

Overall in a comparison of 225 vs 235 tires, 235 tires come with a wider footprint which enables better wet/snow/ice braking performances compared to a 225 tire. However a 225 width tire having a narrow footprint has a better noise performance compared to a 235 width tire.
Is a 205 tire wider than a 225?
A 225/75-15 tire is approximately 28.4-inches in overall diameter when inflated while a 205/75-15 tire is about 27.1-inches. The difference in width between a 225mm and 205mm tire is 20mm, or about 3/4-inch.
255 (Tire Width): The tire width is 255 millimeters from sidewall to sidewall (just over ten inches).
Going from 265 to 275 is fine on your car and you should not notice any difference in driving. It's less than a 4% difference in width: 10/265 = 0.0377).

A 650b wheel is one that's about 27.5 inches in diameter, when measured from tyre edge to tyre edge. This compares to 26in for a standard mountain bike wheel and 29in for so-called '29er' wheels (700c road wheels are also 29in in diameter). What's the Fastest Tyre Size for Mountain Biking?
A metric tractor tire sizes expression may look something like “520/85R42.” The “520” part means the tire is 520mm wide, “R” means it's a radial tire, and “42” is the rim size expressed in inches, just like the standard method.
A standard sized tire will be displayed in inches. A tire that reads 33 x 12.5 R15, is 33-inches in diameter (or tall), 12.5-inches wide, and will fit a 15-inch wheel.
The width of a 305 tire size in inches is 305mm, or roughly 12 inches.

A 245 is 245 millimeters, or 24.5 centimeters, wide. The tread width is actually somewhat smaller than the tire's actual width.
The “235” grouping indicates the width of the tire from sidewall to sidewall in millimeters. So, in this example, the tire is 235 millimeters — 9.25 inches — wide from sidewall to sidewall.
Tire Width
For instance, in a size P215/65 R15 tire, the width is 215 millimeters.
12.5 tires can be fitted on rims 11.0 to 12.0 inches wide.
The ratio between the section width and the rim width is pretty important. If the rim width is too narrow, you pinch the tire in and cause it to balloon more in cross-section. If the rim width is too wide, you run the risk of the tire ripping away at high speed.
Possible adverse effects of wider tires
For one thing, tires may be more susceptible to aquaplaning or hydroplaning. Also, the car will have less control on slippery, loose surfaces like gravel. Elsewhere, a wide tire may not fit correctly inside the wheel. It may protrude outwards.
For example a tire size 285/35-19 has a tread width of 9.9". The ideal wheel width would be 10.0" for that tire.

Is a taller or wider tire better?
Overall, wider tires are better for dry surfaces and for high-performance vehicles. Greater surface area allows for better day-to-day traction and durability.
From a safety point of view, both types have their good sides: On a dry road, wider tires will offer more grip than narrow ones, but the risk of aquaplaning will be higher with wide tires. – In the winter, narrow tires are better under extreme conditions as they provide higher surface pressure against the road.
The section width can be converted to inches by dividing the width in millimeters by 25.4 like so: (225 millimeters) / (25.4 mm/in) = 8.86 inches.

For example a 200/55R18 would be around 26.7 inches tall and 7.9 (200mm/25.4) inches wide.
For example, a 60-series tire features a sidewall that is 60% as tall as the tire's section width. A 50-series tire will feature a shorter sidewall, at 50% of section width.

This is the size of the rim/wheel the tire is fitted to. 17inches. Since you only specified the first, I can only tell you that the 265 is 10mm wider than the 255.
While the exact dimensions of a 245 or a 255 tire can vary somewhat between tire manufacturers, for any specific manufacturer a 255 tire will have a wider section width (bulge or tread width) than a 245 tire, the difference being 10 mm.
You may also notice that some enthusiasts instead choose a much wider tire for the rear axles as compared to what they put up front. The theory behind this is that it gives you as much rubber as possible to transmit power to the pavement, thus ensuring excellent traction for higher horsepower, rear-wheel drive cars.
How much wider tire can I use?
As a general rule of thumb, it's safe to fit a tire up to 20 millimeters wider than stock on the original rim. The actual width of the tire will vary depending on the width of the rim: The tire will expand 5 millimeters for every half-inch (12.5 millimeters) increase in rim width.
The 295 will also hold more weight. The 35 has a maximum load of 3195 and the 295 has a maximum load of 3750. Carolina Classic Trucks Inc.

Comparing 295 vs 33 Tires
In fact, some people mistakenly believe that the 295 tires are the same as the 33-inch tires. The 295 tires, on the other hand, are slightly larger than the 33-inch tires. Compared to the 33-inch tires, the 295 has a diameter ranging from 33.2 to 33.5 inches.
295 is way too small for a 12" wide wheel.
The section width can be converted to inches by dividing the width in millimeters by 25.4 like so: (225 millimeters) / (25.4 mm/in) = 8.86 inches.

Overall in a comparison of 225 vs 235 tires, 235 tires come with a wider footprint which enables better wet/snow/ice braking performances compared to a 225 tire. However a 225 width tire having a narrow footprint has a better noise performance compared to a 235 width tire.
255 (Tire Width): The tire width is 255 millimeters from sidewall to sidewall (just over ten inches). 45 (Aspect Ratio): The tire's sidewall is 45% of the tire's width, which means the sidewall is about 114 millimeters or just over 4 inches.
The 265 would be 40 mm wider than the 225. Be careful to make sure the diameter of the tire is the same with the different size tires. This is one of the in puts to the computer to let it know how fast you are going.
