Below 45 Degrees in San Diego: Consider Winter Tires

Remember snow tires? They were basically just regular tires with big, knobby lugs to get them through deep snow. They were loud and rode hard, and San Diego drivers couldn't wait to get them off the car. Then along came television advertisements for “all-season” radials. CA drivers ran out and bought some and we thought we were done with snow tires forever.Tires have come a long way since then. Modern winter tires sold in the San Diego area are much better designed for the wide range of conditions that come with CA winter weather. They are made with a rubber compound that helps them stay flexible in cold weather. Regular tires become hard and stiff at San Diego temperatures below 45°F (7° C) which reduces their traction. That's a concern in winter, especially with snowy or wet conditions. But it also means that San Diego drivers are better off with winter tires in cold weather even when it's dry.The tread design on winter tires has been improved to move snow, slush ... read more

Wasteful Thinking

With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin.  Some vehicles offer remote starting that let you do that from the comfort of your home or apartment.  But is letting your vehicle idle like that good for it? Manufacturers say it doesn't harm the vehicle.  They say it's because modern vehicles are made differently from those in the past.  Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders.  The engine gets only the fuel it needs, taking conditions into account. Older vehicles, on the other hand, used to use carburetors.  When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions.  Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil. So yes, you ca ... read more

Stay Safe in San Diego by Putting Your Cell Phone on ICE

We don't want to think about it, but each San Diego resident who drives or rides in a vehicle is potentially an accident victim. In the worst-case scenario, those people are unconscious and unable to communicate with CA rescue workers. Rescue workers and San Diego police are well aware of this difficulty, even if the rest of us don't stop to think about it. They can all recount stories of searching through glove compartments, pockets, wallets, purses and cell phone directories for a person's name and for contact information for someone who can help them get the person the medical care they need. This contact information is critical in an accident because San Diego medical workers need to know about allergies and potential drug interactions. Also, in CA, some medical treatments can't be provided without authorization or consent, and there can be insurance and billing issues if the person's medical care is not properly arranged. ICE provides a solution for these con ... read more

John's Automotive Care Tire Safety: Washington vs. Lincoln

  Welcome to the John's Automotive Care automotive blog. Today, let's talk about the effect of tire wear. Let's focus on stopping in wet San Diego conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can't move the water, the tire will actually ride on top of a thin film of water.That's called hydroplaning. If it's really bad, San Diego drivers can actually spin out of control - endangering themselves and the other drivers around them. At best, you won't stop as fast. So how does a tire move water? It has channels for water to flow through. Look at your vehicle tire and you'll see channels: channels that run around the tire and channels that flow across the tire. They're designed to direct water away from the tire so it can contact the road better.And the deeper the channel, the more water it can move. A brand new John's Automotive Care tire has very deep channels and can easily move a lo ... read more

Wishy-Washy in San Diego

Perhaps you've found yourself driving when something all of a sudden splashes on your windshield, obstructing your view. You know that sinking feeling when you try to turn on the windshield washers and no fluid comes out. Now you're blinded even more. What can you do? The best thing is to make sure your windshield washer fluid is always topped off and ready for these situations. You probably figure you'll grab a bottle of that blue stuff you see in the store. But is that really the right choice? One thing you know isn't the right choice is plain water. It can freeze when temperatures drop. Plus, when it's close to the freezing mark outside, spraying water on your windshield can freeze, turning it literally into frosted glass and blinding you suddenly. Water freezing in your vehicle's washer lines can also damage them. There are different types of windshield washer fluid made for different climates. Many have alcohol to prevent them from freezing; their label will usually tell you at wh ... read more
