Co l d tire inf l ation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.

Tire pressure generally refers to t he amo unt of a ir in a tire tha t it
needs it to do its job and safe ly carry the comb ined load of the entire
vehicle and its contents . Tire pressure is measured in kilopasca ls
(kPa), t he inte rnationa l measur ing unit and in poun ds per square inch
(PSI). Tire press ure is based in part on the vehicle's design and load
limit - the greatest amount of weight that the vehi cle can car ry safe ly
and the tire s ize. The proper tire pressure is frequently refer red to as
the "recommended cold t ire inflation pressure. " Air in t he tires
expands when the tire heats up because of internal friction when it
flexes in use . The ti re press ure is hig her when t he t ire has warme d up
than whe n it is "cold." It is the inflation pressure in a "cold" tire that
counts. The refo re, you sho uld never let air out of a warm t ire to
match "cold ti re inflation pressure " recommendations . The t ires
wou ld then be un der inflated and could fail suddenly.

Maintain ing prope r tire pressure is one of the most importa nt things
you can do to he lp avoid sudde n t ire fa ilure . Under inflated tires are a
majo r cause of sudden tire fa ilure . Keeping t ires at the rig ht pressure
is a lso important for safe a nd responsive vehicl e ha nd ling , traction,
braki ng an d load ca rrying.
Tire pressures are particularly impo rtant
when the vehicle is being driven at higher speeds, and then espe·
cially when heavily loaded even within the permissible load·
carrying capacities approved for your vehicle .
The recommended tire pressures for your Audi depend on the kind of
tires on your vehicle and the num be r of passengers and/or amou nt of
luggage you will be tra nspo rt ing .
On USA vehicles, the tire pressure label is located on the driver 's side
8-pi llar. On Can ada vehicles, the tire press ure label is loca ted either
on the driver's side B-pillar o r inside the fuel f iller flap. The t ire pres ·
