Thought some would be interested in this e-mail I got back from Dunlop about the tire cupping on my "06' Wing with less than 5000 miles. Think it is interesting the factory is recommending more tire pressure in the fronts too (38 psi), maybe someone should tell Honda! :shock:
Oh yea, and only use those brakes when absolutely necessary!! :roll:[Thank you for taking the time to contact us regarding your tire
questions pertaining to inflation pressures and irregular tread wear.
You may not be able to entirely avoid irregular wear. Irregular wear
or tire cupping is a somewhat common occurrence on all vehicles.
On a four-wheel vehicle, you are advised to rotate your tires
periodically to even out wear. Unfortunately, you do not have this
luxury with a motorcycle because front and rear tires, unlike those on
a four-wheel vehicle, are not interchangeable.
However, there are steps that can be taken to minimize cupping and
uneven wear on a motorcycle:
1.Maintain your motorcycle and
particularly your front forks and
2.Avoid hard braking whenever possible.
Braking causes the tire to grab
and wear in one direction. When
braking is applied to the front tire, the
load transfer over-flexes the tire
and increases the tendency for cupping
and uneven wear.
3.Maintain your tire pressures.
Underinflation or overinflation in motorcycle
tires are significant causes of
cupping and uneven wear, particularly in
association with hard braking and/or
The recommended inflation pressures for your '06 Honda GL 1800 Gold
Wing are 38 psi front and 41 psi rear if your running the original
equipment tire sizes (i.e. 130/70-18 front and 180/60-16 rear).
