Tires Pressure/Tire Size by Type

Answer 1

Hi, what kind of vehicle do you have? Tires vary in sizes but most tire sizes begin with a letter or letters that identify the type of vehicle and/or type of service for which they were designed. The common indicators are as follows:

P225/50R16 91S- The letter P signifies the tire is a "P-metric" size that was designed to be fitted on vehicles that are primarily used as passenger vehicles. This includes cars, minivans, sport utility vehicles and light duty pickup trucks (typically 1/4- and 1/2-ton load capacity).

T125/90D16 98M

T = If a tire size begins with a "T," it signifies the tire is a "Temporary Spare" ("space saver" or "mini spare") that was designed to be used temporarily only until a flat tire can be repaired or replaced.

LT = If a tire size begins with "LT," it signifies the tire is a "Light Truck-metric" size that was designed to be used on vehicles that are capable of carrying heavy cargo or towing large trailers. This includes medium and heavy-duty (typically 3/4- and 1-ton load capacity) pickup trucks, sport utility vehicles and full-size vans.

195/70R15C 104/102R

C = If a Euro-metric sized tire ends with a "C," it signifies the tire is a "Commercial" tire intended to be used on vans or delivery trucks that are capable of carrying heavy loads.

ST225/75R15

ST = If a tire size begins with "ST," it signifies the tire is a "Special Trailer Service" size that was designed to only be used on boat, car or utility trailers.

Answer 2

If you tire pressure is incorrect, you will find that you use more fuel than necessary, your braking can be ineffective and your grip to the road could be seriously affected as well. Hence, correct tire pressure is crucial to driving performance. There are no flashing lights to let you know when your tire pressure is too low or too high, so it is up to you to stay on top of it.
