Checking and Maintaining Tires
Checking Tires 
To safely operate your vehicle, your tires must be of the proper type and size, in 
good condition with adequate  tread, and properly inflated.
■ Inflation guidelines
Properly inflated tires provide the best  combination of handling, tread life, and 
comfort. Refer to the driver’s doorjamb labe l or specifications page for the specified 
pressure. 
Underinflated tires wear unev enly, adversely affect handling and fuel economy, and 
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more prone to road hazards, 
and wear unevenly. 
Every day before you drive, look at each of  the tires. If one looks lower than the 
others, check the pressure with a tire gauge.
At least once a month or before  long trips, use a gauge to measure the pressure in all 
tires. Even tires in good condition can lose  1 – 2 psi (10 – 20 kPa, 0.1 – 0.2 kgf/cm2
) 
per month.
■ Inspection guidelines
Every time you check inflation, also examine the tires and valve stems. Look for: • Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,  
splits, or cracks in the side of the tire . Replace it if you see fabric or cord.
• Remove any foreign objects  and inspect for air leaks.
• Uneven tread wear. Have an authorized Acura NSX dealer check the wheel 
alignment.
• Excessive tread wear.
2 Wear Indicators  P. 412
• Cracks or other damage around valve stem.
1Checking Tires 
Measure the air pressure when tires are cold. This  
means the vehicle has been parked for at least three 
hours, or driven less than 1 mile (1.6 km). If  necessary, add or releas e air until the specified 
pressure is reached. 
If checked when hot, tire pressure can be as much as  4 – 6 psi (30 – 40 kPa, 0.3 – 0.4 kgf/cm 2
) higher than 
if checked when cold. 
Have an authorized Acura NSX dealer check the tires  
if you feel a consistent vi bration while driving. New 
tires and any that have be en removed and reinstalled 
should be properly balanced.
3WARNING
Using tires that are excessively worn or  
improperly inflated can cause a crash in 
which you can be seriously hurt or killed. 
Follow all instruction s in this owner’s 
manual regarding ti re inflation and 
maintenance.
