Tire Profile vs Ride Quality

Hello Everyone, 
Welcome to new article, 
Everyone wants smooth ride quality, better cornering experience, low cabin noise, good fuel economy, excellent braking capability, good grip in dry and wet conditions etc, 



How To Decide Whether to Go with Low Profile or High Profile Tires

Tire profile is  mainly divided into two types
Low Profile
High Profile 

Low Profiles: Low-profile tires are used mostly on sports cars and F1 race cars to improve a vehicle’s cornering, handling, performance, and looks. A larger contact patch area provides better grip on dry paved roads, and with larger rims and brakes, the cars braking ability also improves alot. However, the ride becomes rough, because tires absorb less shock from bumps. Such tires are a trend, so you may also see them on mostly high-class vehicles.

Aspect Ratio: Low-profile tires come with low aspect ratios (side walls/profiles) – 55% or less. The information is at the beginning of the main tire code, after the tire width. You will see numbers like 215/55, where the two digits after the slash character are the aspect ratio. It shows the relation of te tire height to its width in percent, so on a 215/55, the height will be 55% from 215 mm – 118.25 mm.

Advantages and Disadvantages of Low Profile 

Advantages: 

  • More fuel efficiency.
  • Better looks.
  • Improved grip, cornering, braking, etc.
  • Additional ‘run-flat’ technologies.

Disadvantages:

  • Less grip on irregular surfaces.
  • More noise.
  • Rough ride.
  • Faster wear 
High Profile: Higher-profile tires are generally seen on most of the cars in market they having their USP like they are quieter and may provide a more cushioned ride. They are also cheaper to buy if compared with low Profile Tires.

Aspect Ratio:  High-profile tires come with high aspect ratios (side walls/profiles) – 65% or more. The information is at the beginning of the main tire code, after the tire width. You will see numbers like 185/70, where the two digits after the slash character are the aspect ratio. It shows the relation of tire height to its width in percent, so on a 185/70, the height will be 70% from 185 mm – 129.5 mm.

Advantages and Disadvantages of High Profile 

Advantages: 

  • Good grip on Bad roads (Indian road Condition)
  • Less noise.
  • Good Cushioning
  • Smooth ride.

Disadvantages:

  • No Good looks
  • less stability on high speeds and corner.
  • Basically this tire are for normal use.

Honest Advice 

If You are running is mostly on plain roads you can go with low profile tires. which will provide you smooth ride, cool looks and superb drive ability and performance, they are sportier and they have sharp responses on high speeds.

If your budget is not of upgrading to new rims and set of tires, if your driving is mainly on bad roads stick to high profile tires only.

Interesting Facts About Low-Profile Tires


  • The lowest by now are Kumho’s 385/15 series for luxurious cars like Dodge Viper, Ferrari F430, Corvette Z06, etc. They go along with Nexen 365/15 that the company also showed during SEMA The tires are more for track than for everyday street or highway use.
  • In 1920s, almost all tires had 98% aspect ratio, going down to 70% in 1960s/1970s. The 70s became a new era in tire profile diversity, introducing 65-55% tires to the market. Since that time, 65% became more standard, and now 55% turns more and more regular rather than low-profile.
  • Tire width also matters in low-profile tires, as 225/50 and 205/55 will have almost the same height (varying by 0.25 mm). Many drivers pay attention only to the aspect ratio, often choosing the wrong size. Some also pay more for a particular profile, while cheaper tires may have the same height.
  • Some manufacturers recommend about 0.2 bar higher pressure for the low-profile tires that are OE for a particular vehicle. This isn’t a rule, but more air will handle the load of the car better. However, remember that over-inflation reduced ride comfort, and under-inflation may cause irreparable damages and overheat.
