Dover’s Difficult Mile a Monstrous Challenge: 

Dover has long been a track on the NASCAR circuit that presents many challenges for
drivers, teams and Goodyear.  A lot of what Goodyear builds into its tire
set-ups falls into two categories – compounds and constructions.  The
compounds run this weekend have been developed over many races
and many tire tests to lay rubber down on the concrete track surface.
At Dover, it's easy to see the impact of this tire set-up as the track starts
to turn from white to black as soon as cars hit the track.  The construction
of the current Goodyear tire combination has continued to evolve to
accommodate the lower air pressures teams run as NASCAR moves
toward a lower downforce aerodynamic package, while at the same
time being able to handle the speeds and loads that Dover’s high banks
produce.
 
Notes:

Teams in all three NASCAR series in action at Dover this week will
run the same right-side tire code, though Cup and Xfinity Series teams will
run a different left-side code than those in the Camping World Truck Series.

This is the same tire set-up that Cup teams ran at Dover in both races
last season.

In the Xfinity Series, teams ran this right-side tire code
(D-4696) twice at Dover in 2016 and while they ran this left-side tire code
(D-4684) at other tracks last season, this is the first time they are running
it at Dover. Compared to what Xfinity teams ran at this track last season,
this left-side features a compound change for more grip.

Teams in these two series ran this left-side code at Chicagoland, Homestead and Texas last
year, while Cup teams ran this right-side code at Darlington. Dover is
unique among NASCAR ovals of one mile or less in length, in that inner liners
are required on all four tire positions and air pressure in those inner liners
should be 12-25 psi greater than that of the outer tire.
