Tire Mold Release
Q. Mold Release - Do any manufacturers of MC tires use this, and is this why a tire need to be 'scrubbed in?

A. There is NO manufacturer that uses mold release on the tread area of the tire. Approximately 70% of any tread compound is oil. During the curing process, oil rises thru the compound and forms a natural release agent against the metal mold. After curing several tires the molds "Seasons" from the oil and look like granny's "Cast Iron Skillet".

The surface of any tire has to be mechanically abraded to get to the rubber compound used for traction... removing the oil that has risen during the curing process.  Anyone that has seen tires from the race track that are "BLUED" will understand that this is also the oil in the compound rising to the surface.

Tire Compounds for Street
Q. If I want to be a faster rider through the canyons, shouldn't I be running Race Compound tires so that I get maximum grip?

A. Tires used on the race track are design for the track.......not the street.  Normal operating temps (internal not surface) for a race compound tire are around 90 degrees centigrade (around 200 F). 

Street compounds have a operational window of around 50F ~ 150F.
Race compounds have a operational window around 120F ~ 280F.

This higher temp is needed on race carcasses to enable the extra stickiness.  Taking these same racing compounds and trying to use them on the street could be dangerous, simply because your operating temperatures will rarely reach the optimum temp levels.  In turn, the tires may actually provide less traction than the corresponding street compound.

 

...Conclusion - Utilize the new generation of  "aftermarket high-performance" skins; you read about their great performance on this website all the time.
These new design compounds are a hybrid, resulting in the best of both worlds.  Tire designs are can be found to fit you style of riding, for example you may find a tire that presents characteristics for 70% sport riding, 30% track riding, making it a great fit for those who primarily carve the canyon, while doing the occasional track day.

Tire Balancing
Q.  Balancing - is there any practical difference between "Computer Spin Balancing" and an "old fashioned" balancing jig, in terms of high performance sportbike tires (road, not race)?
Is it a safety issue, particularly with the high-speed, high-stress environment many sportbike tires encounter?  I'm asking because many people are interested in mounting their own tires, but are reluctant to do so if it might endanger their safety...

 

A.  It is VERY critical that all street tires be balanced. Non-balanced tires develop problems exponentially as the speed rises. Poor ride, vibrations, chatter and irregular wear can result from non-balanced tires. Preferred balance methods prioritized in the following order,

  • Static balanced as in racetrack method, this is the most accurate method with experienced technician. Scissor needle bearings make this balance method accurate to with-in 2~3 grams. 

  • Computer balanced. 

  • Bubble balanced, just better than no balance at all.  Very sensitive to technician handling and balancer set-up.

 

Tire Tread Patterns
Q. I have a question about tread patterns - Does tread pattern affect grip on dry roads? Does a slick tire have more grip on dry roads than one with tread pattern? About wet roads - Does tread pattern affect grip on wet roads? If the road is just wet, not submerged under water, will a slick tread tire provide more grip than a tire with tread? And if the road is submerged, will the tread channel water out so it won't hydroplane and provide more grip?

A.  Let's visit a couple of issue before we answer the direct questions.

  • Slick tires are for use ONLY on a closed course or track environment.

  • Tires (compounds & constructions) are designed to operate at certain temperatures and certain conditions, race tires at high temps..............street tires at much lower temps.

  •  Slick tires have the most grip on the racetrack, given the compound choice is correct. Compound choice is relevant to expected operating temperature .

  • Tread pattern has a small influence on dry grip, but the pattern is there to move water away from the contact patch.

  • Tread pattern moves water away from the contact patch and allows the compound to grip the road surface. Otherwise Hydroplaning occurs. 

  • Slick tires will work on a damp surface. When only a small film of water develops, slicks will Hydroplane.  

  • When the water depth become too deep, even patterned tires will hydroplane.

 

Insurance Motorcycle
Q: What about insurance?

 

A: You should know that riding motorcycles is and can be dangerous and risky, more so than in automobiles. 

 

Although it is not frequently discussed, the fact remains that you need motorcycle insurance to protect you from the overwhelming loss that can occur in an accident. Well thought out coverage ensures no great loss of income or economic burden that could disable you financially after an accident. There are different kinds of coverage that pay for different kinds of loss. This is what confuses many riders when they buy motorcycle insurance. Not having the right kind of coverage can be devastating. It is like going into battle with holes in your armor.

 

In Texas you are required by law to carry a minimum amount of liability insurance to legally operate a motor vehicle on the roads. In general, liability coverage pays for damages to others if you cause an accident and injure another person or damage their property. Your injury or loss is not covered by this insurance coverage.

 

Part of the liability coverage is for bodily injury liability, a type of coverage that you are required by law to carry in most states. A legal minimum in many states is as little as $10,000 per person, per accident. Your coverage pays for injury to others when the accident is your fault. Important- remember that loss above that amount is not covered and the other person can seek legal action to obtain a judgment against you for that amount. 

 

If you are involved in an accident and the other driver is at fault, then the other driver’s property damage liability coverage pays for your injuries and motorcycle damage. Property damage liability insurance is required by law, but the legal minimum amount for this coverage in some states is only $5,000 per accident. So, if a driver with the $5,000 minimum totals out your $15,000 bike, his insurance company will pay you only $5,000. How will you get the other $10,000? If the other driver files for bankruptcy, you end up with nothing. That is where underinsured motorist coverage is important.

 

If you purchased underinsured property damage coverage, you may be able to collect the other $10,000 to fix your bike. This insurance is used to “fill the gap” between the actual amount of damages and what the other driver’s insurance paid, but only if the other driver caused the accident and only if you purchased limits high enough to cover all of the remaining damage. In other words, if the legal minimum requirement in your state is $5,000 for property damage liability; and you drive a $15,000 bike, you should have at least $10,000 limits on you underinsured property damage.

 

Underinsured motorist coverage picks up where the other driver’s insurance runs out. This typed of insurance is very important. If you are injured in a motorcycle accident, break your leg, spend a week in the hospital and are off work for six months, and experience a great deal of pain and suffering, but the other driver only had a minimum liability policy on their vehicle, you are left holding the bag. For example, someone else caused an accident, crashes into you, and puts you in the hospital with serious injuries. You end up not working for three or four months (if you have already used all your sick time and all your vacation time, you will receive no income until you go back to work). To make matters worse, the co-payments on your medical bills, if you have insurance, are several thousand dollars. So, if someone else causes an accident with you, and they only carry the $10,000 minimum, what will you do if your damages amount to more than $10,000? The average one night stay in a hospital is around $4,000, so you can see how easily and quickly medical bills can add up. And what about your lost wages? Finally, you are entitled to an amount for your pain and suffering. You need underinsured motorist coverage. It might be wise to consider strongly this insurance.

 

Underinsured motorist coverage is usually sold along with uninsured motorist insurance.

 

Uninsured motorist coverage is a very important insurance coverage for you to consider. In many metropolitan areas of the country the other drivers may be uninsured. These uninsured drivers can make up as high as 40% of the drivers on the road! The motorcycle driver is not at fault in most accidents. Therefore, you have a high probability of being hit and injured by a driver who has no insurance. The only way you can protect yourself is to purchase uninsured motorist coverage. Uninsured motorist coverage pays for medical expenses, property damage, and pain and suffering (however, there are limitations in no-fault states). We strongly recommend that you purchase this insurance and do not drive without it. Many riders mistakenly believe uninsured motorist coverage pays only for medical bills, and that they do not need it because they carry health insurance. WRONG!-- it pays for medical expenses, as well as loss of earnings, and pain and suffering.

 

It is a very good good idea to talk to your agent, or talk to several agents, to determine the best coverage that will provide the most protection against loss that you can afford. Then again what can you really afford to loose or be responsible. You need to remember that different insurance companies have different exclusions to their insurance policies. The most common for motorcycle policies is the passenger exclusion, which means that your insurance company will not pay for injuries to your passenger under your bodily injury liability coverage if you were at fault. There are other types of exclusions that, unless you ask, you may never know about until it is too late. Therefore, the most important thing you can do is to fully understand you entire coverage.

 

Collision is a type of insurance that pays, after your deductible has been met, for your bikes repair if you hit anything, even something like a dog or a deer, or if the accident was your fault. Many times bike component add-ons are excluded or value reduced by the insurance company. Understand this. 

 

Comprehensive is a type of insurance that pays for your bike, after your deductible has been met, for the replacement of your bike if it is stolen, suffers damage from fire or hail, or is vandalized. Again there are exclusions and deductions.

 

The time to find out about coverage and exclusions on any policies is before you buy it. Before you sign anything, ask your insurance agent if there are any exclusions or notice requirements in the policy. Always ask to have all exclusions and notice requirements explained to you before you buy any insurance.

 

RECOMMENDATION
A critical insurance coverage to consider for bike riders is uninsured and underinsured motorist coverage. This type of coverage could be extremely important, because 2/3 of motorcycle accidents are caused by the other driver.

 

You need to protect yourself just in case your injury is more than minor, such as a broken leg or foot. Hospital bills, loss of wages, and pain/suffering together can easily be greater then the minimum liability coverage in All States. In that your losses are frequently much greater than the other persons coverage.

 

Consider Uninsured/Underinsured coverage of 100/300 limits. That means $100,000 per person, $300,000 per accident. The insurance carriers require you purchase liability insurance at the same level. This is not a problem because additional coverage is not a lot of money, usually $90 to $110 per year.

 

If you have any questions about types of policies or limits of coverage contact your  insurance agent ASAP.
