yes and no you cant go to wide or youll have rubbing and you cant go to thin or youll lose handling i genrally go with a wider tire in the rear and a thinner tire in front
No, you have to buy a wider tire.
205 is the width of your tire the 65 is an aspect ratio that determines how tall the tire is compared to the width
It usually can
The width of the contact patch of the tire on the road.
No, it is not safe to use a 2.125 tube in a 2.25 tire as the tube may stretch too thin and be more prone to punctures or blowouts. It is recommended to use a tube that matches the tire width for optimal safety and performance.
No, the tire width number is higher for wider tires. Tire sizes are typically expressed in a standard format, such as "225/45R17," where the first number (225) represents the tire's width in millimeters. Therefore, a tire with a width of 225 mm is wider than one with a width of, say, 195 mm.
The width of the road.
To determine the width of a tire, you can look at the sidewall of the tire where the size information is usually printed. The width is typically indicated in millimeters and is the first number listed in the tire size. You can also measure the width of the tire using a ruler or tape measure if the size information is not visible.
A tire's section width (aka"cross section width") is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. This measurement is made without any load placed upon the tire. The rim the tire is mounted on affects this measurement. On a narrow rim the measurement would be "narrower" than if the same tire was mounted on a wide rim. The industry rule of thumb is that for every 1/2" change in rim width, the tire's section width will correspondingly change by approximately 2/10". For example: a tire in the P205/60R15 size is measured on a 6.0" wide wheel and this size tire has an approved rim width range from 5.5" to 7.5" wide. The tire has a section width of 8.23" (209mm) when mounted on a 6.0" wide wheel. If that tire were mounted on a rim: 5.5" - 8.03" cross section width 7.5" - 8.93" cross section width It's mainly important for (fender, frame)clearances, but a narrow rim should give a softer ride due to sidewall positioning, but less grip due to tread not less flat, more sidewall roll.
That is the tire profile or section width. The number is a metric figure standing for the width of the tire in millimeters.
265 on a tire is the width of the tire in mm
A 295 tire typically has a section width of approximately 295 millimeters, which is about 11.6 inches. This measurement refers to the width of the tire when mounted and inflated. The actual width may vary slightly based on the tire's specific design and the rim width it is mounted on.
