Good day to all members of GWRRA and I hope your last ride was smooth and enjoyable.

Hey, have you been riding yet? The rain has stopped and the sun is out and shining it's time to RIDE! You've done your checklist like you do EVERY TIME before you ride, RIGHT?

When you were checking those tire pressures did you look at the tread of each tire? Are there ANY cracks in the rubber? Feathering of the tread? Any lumps, bumps, cuts? Any leaky valve stems? Missing valve cap? CORDS!!!!

Yes, I know. "I can't see much of the rear tire!" Put something on the floor and lay yourself down so you can SEE the tire as you roll the rear wheel by hand. Take a flashlight or shop light with you when you get down there.

PLEASE NOTE: You do have it on the center stand right? If not then PUT THE BIKE ON THE CENTER STAND! You Trike guys need the rear of the bike on jack stands so you can roll the rear wheels by hand to inspect the inboard side of both rear tires. To inspect the front tire with ease, have your Co-Rider sit on the back of the bike and have them lean back, works even better with a full trunk and saddle bags.

Is the tread wearing funny? Just doesn't look right? Feathering or cupping? Something is not right then it needs to be addressed NOW! Most funky tread wear is caused by improper inflation pressure and or overloading of the bike!

Here is what two of the major manufacturers have to say about motorcycle tires and their care.

DUNLOP: As the world leader in motorcycle tires, Dunlop continues to be concerned about the lack of attention paid by many cyclists to proper use and maintenance of their tires, particularly when fitted to motorcycles intended for touring.

Dunlop technical personnel have attended touring rallies all over North America to collect vital data and give instructional seminars. What we have observed at these rallies alarms us; many touring riders are not following proper tire maintenance procedures. The requirements for proper tire usage are not complicated, but they do require consistent attention.

Owners and operators of motorcycles should closely monitor vehicle loadings to insure they are within the maximum loads and corresponding inflation pressures for their tires. This basic load and pressure information is clearly stamped on the tire sidewalls. The tire does not support the load-the air pressure does. The manufacturer's ratings for the maximum load and inflation pressure are critical tire design elements. If not observed, the handling and performance of your motorcycle will be greatly affected. We have checked inflation pressures at several touring rallies and found a high percentage of rear tires to be underinflated. In addition, weight checks of the rear axles of these motorcycles indicated a number of tires were loaded beyond maximum capacity.

Our inspections have not been limited to those cycles fitted with Dunlop tires; the situation exists for all brands of tires. Regardless of the make of tire, this is a serious problem. Riders of motorcycles with significantly underinflated and overloaded tires will experience handling and steering difficulty. In addition, this abuse will result in disappointing premature tire wear and may cause catastrophic tire failure. The addition of accessories, cargo, and dual riding to touring motorcycles aggravates the problems of overloading and under inflation. The excessive flexing that results from under inflation or overload causes buildup of internal heat, fatigue cracking and eventual carcass breakup resulting in complete failure. A consequence of such failure may be an accident with serious personal injury or death.

The appearance of stress cracks in the tread grooves is one indicator of overload and/or under inflation. If you find evidence of tread groove cracking, you should remove and replace the tire immediately. This damage is permanent and non-repairable. Our inspection of tires of various style and manufacture at rallies and our subsequent testing have confirmed that under inflation (and/or excessive load) causes tread groove cracking and can result in more serious damage within the tire body. Uneven wear may also accompany underinflated use. Failure to heed these visual warnings can result in tire failure or blowout.

The use of trailers can also contribute to tire damage and touring motorcycle instability. Although most motorcycle manufacturers recommend against their use, a percentage of the motorcycles we have inspected were so equipped. The trailer tongue weight added to an already heavily laden motorcycle can fail a rear tire. The percentage of overloaded motorcycle rear tires found during our inspection would have been higher if trailer tongue weight had been considered. The forces of rapid acceleration and deceleration may also multiply the effects of trailer tongue weight.

To get the maximum safe use out of your tires and maximum touring enjoyment you should:

1. Properly maintain all aspects of your vehicle in accordance with manufacturer's recommendations. Read and reread your motorcycle owner's manual.
2. Never exceed the loading and accessories restrictions found in your motorcycle owner's manual, or the maximum load displayed on the tire sidewalls. Know your loaded vehicle weight!
3. Check air pressure at frequent, regular intervals, particularly just before and during long trips. Always use an accurate tire gauge* and check pressures only when the tires are cold (i.e., wait one hour after running). We have found many cheap gauges to be off more than 5 psi, so be sure to use a top quality gauge and preferably one that retains the pressure reading until reset!
4. Inspect your tires as often as possible. Look for irregular wear, any signs of cracking in the sidewalls and tread, blisters, knots, cuts or punctures. Immediately remove and replace damaged tires.

If in doubt, ask your motorcycle tire dealer to check your loading, inflation and tires. Remember, your tires stand between you and a serious accident. For touring motorcycle loading, follow these general guidelines:

• " Light loads-single rider with some luggage (up to 200 lb. total)-minimum tire pressure of 32 psi front and 36 psi rear must be maintained.
• " Heavier loads-dual riding and/or luggage (from 200 lb. total up to maximum motorcycle capacity stated in the owner's manual)-pressure of 36 psi front and 40 psi rear must be maintained.

Please Note: For any dual riding or fully loaded use, 40 psi must be maintained in all Dunlop rear tires fitted to touring motorcycles.

In addition to following these recommendations, notice what your tires are telling you while you're riding. If your steering response is slow or mushy, or if cornering and braking response is heavy, there's a good chance your tires are underinflated. Vibration or wobble may signal that actual tire damage has occurred and failure is imminent! If you conscientiously follow our recommendations, you will enjoy better, longer and safer tire performance and many, many miles of touring pleasure.

METZELER: Always inflate tires to the correct pressure as indicated in the owner's manual.

However Metzeler North America has found the air pressure suggestions listed below will improve mileage and customer satisfaction especially if an emphasis is placed on running the air pressure towards the maximum as stated on the sidewall. Check cold tire pressures frequently. Correct tire pressure is crucial for safe handling. Over inflation may impair ride comfort and reduce the contact patch between the tire and driving surface of the tires. Insufficient air pressure will result in poor handling and cause a tendency for the motorcycle to "wander". In addition, improper and insufficient tire will cause accelerated tire wear, increased fuel consumption, less control and the possibilities for tire failure to due an overload/under inflated operating situation.

I've got over 10K miles on my Dunlop E3's. I have a little feathering on the rear but the front is in top shape and will give me at least another 8K miles.

I hope everyone enjoys my article and finds any bit of it helpful. May great weather, friends and rides find you till next we ride together.
