What does 88t mean on a tire

What do the numbers on tires mean? The tire size is just one small piece of this code. Read on to learn how to crack the tire code with this handy guide dedicated to tire types, sizes, and construction. Tire service type ratings Most tire sizes begin with one or more letters — for example, P or LT. The letter tells us what type of vehicle or service the tire was designed for. Euro-Metric sizes are equivalent to P-Metric sizes in dimensions, but Euro-Metric sizes have subtle differences in their load-carrying ratings and capabilities. These tires are designed for use on vehicles used to tow trailers or carry heavy loads. LT — Light Truck suffix Example: 9. Also known as mini spares or space savers, temporary spares are designed for short-term use until the regular tire is repaired or replaced. In addition to the C designation, these sizes are also branded with a load range and service description rating load range B, C, or D. The three digits following the service type prefix if present tell us the cross-sectional width of the tire in millimeters. In the example above, the tires width, measured from the widest point of the inner sidewall to the widest point of the outer sidewall when properly mounted, is millimeters. The section width can be converted to inches by dividing the width in millimeters by A lower aspect ratio means a lower-profile tire with a shorter sidewall, while a tire with a higher aspect ratio will have a taller sidewall and look more like a donut. Because we know that the tire size shown in this example has a section width of 8.

This is to prevent a potential oversteer condition.

Wages, employment opportunities, and growth projections for STEM jobs. Discover how to choose the right 3D printer for your needs and the key performance attributes to consider. Optimize your designs, reduce machining time, and lower your costs. The 88T is the load and speed rating. As for the F1 question, please see this post from a chap called Clausius2 on physics forums:. That contact must be the contact of two infinitely rigid surface, with no deformation, as we are said in the elementary physics class. Later, in tribology of machines one realises that friction is made up by means of adhesion, and the theory of adhesion talks about microwelding and deformation of both surfaces.

When it comes to tires, the alphanumeric jungle imprinted on their sidewalls often induces a foggy-eyed gaze from most vehicle owners. The load index 88 in this case is a numerical code associated with the maximum load a tire can carry at the speed indicated by its speed rating under specific service conditions. An 88 load index equates to a load capacity of lbs. Each letter signifies the maximum speed at which the tire can carry a load corresponding to its load index. For instance, a tire with an H speed rating can carry its rated load up to speeds of mph. An 88T marking on a tire means it has a load index of 88 and a speed rating of T.

Tires have an expiration date, it's usually about six years, and when it's reached they need to be replaced even if they have zero miles on them. Sports car owners are more likely to encounter this speed rating than owners of typical family sedans. It is usually represented in kilograms. The letter tells us what type of vehicle or service the tire was designed for. Tires usually come in the following widths in inches : 8, 10, 12, 13, 14, 15, 17, 18, 19, 20, 22, 23, 24, 26, and Read more: Five things you should know about a spare tire.
