The basic rim size must always be 16 inch, however within limits you can change the width or aspect ratio.
You can not mix different size tires and rims. The tire has to be the same size as the rim.
It wont. They will only change when you increase/decrease the size dramatically as the wheel or tire. A one inch change wont make a difference.A more accurate answerIt's true that the size of the rim does not directly have any impact on the speedometer accuracy. But changing the rim size generally means that you'll be changing the size of the tire. The speedometer is directly affected by the circumference of the tire that is used. If you use a tire with a 10% larger circumference, the speedometer will indicate that you're going 10% slower than you really are. If you match the circumference of the 14 inch tire to the circumference of the 15 inch tire, the speedometer accuracy will not change.
It depends on the tire. It could be made for a 15, 16, 17, etc size rim.
No
That depends on the rim width and the vehicle it is installed on.
That depends entirely on the application.
It all depends on the application.
the R stands for RIM , Example R15 Is a 15 Inch Rim The R actually means it is a tire of Radial construction. The wheel & tire diameter is 15" but the width of the rim should be 7" to 8" for this size tire.
No!. It is very unsafe to mix tire and rim sizes.
what is the largest tire I can put on a stock 20 inch 2008 dodge ram rim
No, the R15 means that it is a radial tire and the 15 is the rim size. Never try to mount a tire and a rim that are different sizes.
A change in overall tire height will change speedometer accuracy.
