XL= reinforced or extra load tire. It may also appear as xl, EXTRA LOAD, or RF on the tire side-
wall.
The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
vehicle equ ipment during the model year, al-
ways compa re the tire size designation on the
tire pressure label on your vehicle wit h the
tires on your vehicle. Make sure that the t ire
size information on the vehicle label is the
same as the size of the t ires on the vehicle.
This is especially important if the vehicle be-
longs to someone else or you bought the vehi-
cle with different rims/tires or you boug ht the
vehicle as a previously owned vehicle.
Remembe r, your safety and that of your pas-
sengers also depends on making sure that
load limits are not exceeded. Vehicle load in-
cludes everybody and everything in and on t he
vehicle. These load limits are technically refer-
red to as th e vehicle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat-
ing ("GAWR") is the maximum load t hat can
be ap plied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker label located on the
driver's side B-pillar. The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupants and luggage or
other cargo t hat the vehicle can carry. For the
