Can you replace R17 tires with R18 tires?
An 18-inch tire, for example, will probably weigh at least a couple of pounds more than a 16- or 17-inch tire. That could also be true of a larger-size wheel. But replacing a standard 17-inch alloy wheel with an 18- or 19-inch alloy rim will add weight — unless it’s an expensive, lightweight type.
What’s the difference between R17 and R18 tires?
It comes down to more subjective measures, apparently. The smaller 17-inch tires represent the most comfortable ride thanks to the larger sidewall. The 18-inch tires create a bit more road noise, and this is further exacerbated when the car jumps up to the 19-inch wheels and tires.
What size tire can you put on a 17 inch rim?
The largest tire size that will fit on a 17-inch rim is a 54-inch tire in diameter (54/19.5R17). The bigger the tire, the more grip and stability on the road while driving and turning. However, drastic tire changes can cause some issues for braking systems and speedometers.
Can you put R17 tires on r16?
You have to replace tires and wheels. You can’t put a 17 inch tire on a 16 inch wheel. You have to purchase both.
What does r18 mean on tires?
The figure “18” indicates the wheel rim diameter in inches, while “95” is the load index, indicating the maximum weight the tire can bear; 95 equates to 650 kg. Then comes the letter “H” which is the speed index, where “H” signals a maximum speed of 210 km/h. “SSR” indicates that this is a “SelfSupportingRunflat” tire.

Is it okay to change all four tires with a different aspect ratio?
Can I Change Tire Sizes? That said, the only dimensions you can change are the width and aspect ratio — never the wheel size, unless you buy replacement wheels — and you should always strive to keep the total height of the tire the same as the OEM.
How do you calculate tire size?
The first number on a metric tire is the width in millimeters. Divide this number by 25.4 to get the inch equivalent as there is 25.4 mm in 1 inch. The third number generally preceded by an “R” is the wheel diameter. The sidewall or aspect ratio are used in metric tire sizes to determine the overall height of a tire.
How wide is a 245 tire?
245/45R17 tires have a diameter of 25.7″, a section width of 9.6″, and a wheel diameter of 17″. The circumference is 80.6″ and they have 786 revolutions per mile. Generally they are approved to be mounted on 7.5-9″ wide wheels.
What is the height and width of a tire?
Tire Width is the width of the tire measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P215/65 R15 tire, the width is 215 millimeters. Aspect Ratio is the ratio of the height of the tire’s cross-section to its width.
What is tire size?

Tires in these sizes are typically found on most passenger cars, light-duty light trucks, SUVs, minivans , and vans. Tires with a rim diameter measured in inches are called “inch rim” sizes.
