-P stands for Passenger
-LT represents Light Truck
-245 indicates tread width (in millimetres)
-The number following tread-width measures aspect ratio or profile height relative to tre’ad cross-section width in percentages
-R signifies Radial construction type; all tyres sold today are radial’s meaning they have ply cords running radially across the tyre.
-18 here specify Rim Diameter also measured in inches next digit after Aspect Ratio multiple by two gives precise measurement of Wheel rim diameter these tyres can fitted onto
Fact 2: Tire dimensions play an important role in automobile performance:
The correct wheel fitment including offset , as well as appropriate load capacity limits determined by maker compliance requirements must be followed strictly while purchasing Tyre set . You’ll find optimum measurements quoted inside vehicles user manual usually under section titled ‘Tyre Information’. Dimensions impact parameters related directly speedometer reading e.g If using smaller Tyre diameter than specified one’s expectation would be faster Speed indicated then real plus acceleration rate could reduce thus compromising Safety factor Since every vehicle has suspension settings continually Checking tyre specifications becomes paramount towards owning safe reliable driving experience.
Fact 3: Different types of tires require different sizing considerations :
Whether seeking performance-focused high-performance slicks for racing or daily all-season tread tires- Tyre manufacturers formulate size recommendations with specific vehicle types in mind. For upgrading to wider rims, one must ensure that not only Tyres match width requirements but sidewall profile as well otherwise many electronic safety features equipped do work properly .

Frequently Asked Questions (FAQ) and Answers on How to Identify Tire Size
As a car owner, one of the essential aspects you need to familiarize yourself with is identifying tire size. It’s not uncommon for drivers to experience confusion or uncertainty when it comes to picking the right tires for their vehicles. In this blog post, we are going to answer some frequently asked questions (FAQ) and provide insightful answers on how to identify your tire size.
So let’s dive in!
Q: Where do I find my tire size?
A: Your tire size can be found on the sidewall of any of your vehicle’s tires. This code typically begins with a letter sequence followed by numbers indicating different values such as section width, aspect ratio, wheel diameter and load index included on the sidewall.
Q: What is my tire’s section width?
A: Section width refers to the distance in millimeters between one edge of the tread groove across to its opposite side.
Q: What is Aspect Ratio?
A: A two-digit number after an oblique stroke indicates an aspect ratio that compares your wear patch height against its cross-section width over time based upon numerical rankings usually 55 or 60 which indicates a bit less rubber percentage versus rim diameter than other numbers shown next along leftward curves towards 70s-90s range and beyond these numbers where larger ratios may have very low profile sizes tied only at center affecting large impacts quite easily; consequently leading into greater flexibility from radial damping rates too much though admittedly strength withstand capacity lowered accordingly if higher percentages are marked out here anyway :).
Q: Why does Wheel Diameter matter in Tire sizing?
A:The wheel diameter correlates directly with overall ride quality because bigger-diameter wheels accompany lower-profile tyres – these will trade off comfort levels for better road feedback through steering columns without compromising rim protection; conversely speaking smaller-size rims could accommodate wider layers providing extra shock absorption while sacrificing cornering stability due largely caused uneven mass distribution created generally perceived safety incidents among many drivers checking load capacity ratings set by manufacturers themselves still advisable follow instructions included always,
Q: What is Load Index?
A: A two or three-digit number followed by a letter character indicates its tire’s maximum allowable weight rating when mounted and determined from tests conducted on dynamometers. Once it has attained this index value, we can cross-reference data gathered about the total mass score using wheel alignment tools at workshops where additional checks come from knowing actual poundage so as not to meet pressure demands in weighing down car more than intended during regular use.
Q: How do I compare my existing Tire size with New Ones before Purchase?
A:The simplest way to compare your current tire’s size with another is just swapping out one for the other on any corner of your vehicle —once you see which side fits best without overhanging leftward rightward clearance margins then check inflation values recommended previously outlined also search proper speed and loading indicators listed following guidelines placed near the sidewall covering up full height unless they have legible codes that are easy enough decipherable upon closer inspection such fonts; finally making sure no physical damage occurred usage time warranted changing done same day.
Conclusion:
Identifying tire sizes isn’t rocket science, but it requires an understanding of some critical terminologies like section width, aspect ratio, wheel diameter load index, among others. Knowing these details will help you choose the appropriate tires to maintain safe driving conditions while keeping the fuel efficiency optimal.

Mastering the Basics: A Comprehensive Guide on How to Decode Different Aspects of a Tire’s Sizing Information
When it comes to choosing the right tire for your vehicle, understanding its sizing information is crucial. It’s not just about fitting the tire to your rim – it’s also about ensuring you get optimal performance, comfort and safety.
Tire sizes may seem confusing at first glance, but once you’ve mastered the basics, they become quite intuitive. In this comprehensive guide, we’ll walk you through everything from decoding sidewall markings to understanding load ratings.
Let’s start with an overview of a typical tire size: P225/60R16 97V
The first letter indicates the type of tire:
P = Passenger (the most common)
LT = Light Truck
ST = Special Trailer
T125 / 70R15 95 M would be used in spare tires only and T135 / R15 78 S are Temporary Spare tires or Compact Spares as some cars refer them too.
Next up are three numbers that indicate the width of the tire in millimeters:
225 indicates that this particular model has a width of approximately 225 mm across its tread face when installed and inflated correctly on a compatible rim.
Following this number is slash “/”, which signals aspect ratio:
Aspect Ratio refers to how tall is this tyre’s profile compared to its width. A higher aspect ratio means more rubber between wheel hub and street and can improve ride quality/highway stability while sacrificing responsiveness during turns. Even then One example could be presented here like these values creates a circumference so smaller tires have quicker response time yet harder ride while bigger ones provide smoother rides albeit slower reactions times.
In other words if we consider P215/55/R17 sizings as per Aspects factor:
– The “215” represents Width
– The “55” representing percentage – This will show us Tyre Aspect Ratio in Percentage (55%).
A lower figure promotes better handling for cornering or reduces rolling resistance meaning economy rating tyres. A higher number often means a smoother ride and will increase your total rolling diameter in comparison to the tire with lower Aspect Ratio, which has its own undermentioned implications.
Going back to our example of 225/60R16
The aspect ratio here is 60%, meaning that the height of this tire’s sidewall is equivalent to 60% of its width.
Then comes the letter “R”, which stands for radial construction:
This refers to how the layers inside a tyre are arranged i.e whether they’re crossed diagonally (radial) or from edge-to-edge (bias-ply). Almost all modern vehicles use radial tires as they’re more stable at high speeds, long-lasting, quieter than bias-ply counterparts,
Finally, we get to two numerical ratings: load index and speed rating –
Load Index Number indicates Maximum weight-bearing capacity allowed for each Tire Size-cum-Construction-type-scale Basis as supplied by tyre manufacturers ranging from Load Index Ratings’ lowest limit(71 pounds per tire) right up till some values can reach high levels up towards thousands range depending upon models utilized while Tyre Speed Rating indicates maximum safe driving speed recommended for that particular size with full load content providing confidence level for users.
97V for P225 / 60 R16 tells us That:
Load Index – Indicates an amount equaling either around something close maybe above approximately about almost exactly 1609 – if converted from kilograms into pounds usually round off compliance factors.
Max Safe Driving Limit Speed – As it talks about V, This specifies tyres had been certified successfully managing car workings proficiently upto a permitted top-most velocity of roughly between around say 149 mph nearly equals among others such designated criteria
Now you know what each element on your tire’s flank signifies!
On top of these key aspects explained earlier; there are also various additional markings worth understanding, including DOT codes showing date/mode/year/locality plant code applicable when quizzed up.
All this data is essential to choosing the right tire for your vehicle, so it’s worth taking a few minutes to familiarize yourself with how to read this information beforehand next time you’re shopping!
