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

Upsizing Wheels and Tires With John's Automotive Care

Many San Diego drivers want to accessorize their vehicle - you know, make it theirs. One of the easiest ways to get a custom look is to get some new wheels. There are thousands of wheel designs at San Diego area tire shops to get you the look you want. And for many San Diego drivers, that look includes bigger wheels. It used to be that cars came from the factory with 15 or 16 inch wheels. Now 16, 17 and even 18 inchers are standard. And the factories are offering optional wheel packages up to 20 inches or more. So let's talk about what to consider when you want to upsize your wheels. It's not exactly a DIY project, so you need to know a thing or two before you get started. The most important term to know is rolling diameter. The rolling diameter is simply the overall height of your tire. Unless you want to modify your vehicle suspension, you'll want to keep your rolling diameter the same when you upsize your wheels.Let's think about those three golden doughnuts in front of you.

Steer Right in San Diego

Virtually all vehicles come with power steering, so many San Diego drivers have never driven a car or truck without it. Power steering assists you when you turn your vehicle steering wheel. Without it, it would be very hard to steer. Now this power assist comes in a couple of forms. In recent years, a lot of vehicles have an electric motor that reduces steering effort and helps improve performance and handling. The other kind of power steering is hydraulic. This is the kind most older CA vehicles — and a lot of newer ones — have. Power steering fluid is pressurized by a pump and is used to assist steering. Of course, vehicles need the right amount of fluid in the system. If it's too low, your steering is affected and you could damage your vehicle pump. Also, power steering fluid can become corrosive over time and damage the pump, hoses and connectors, leading to leaks and repairs. Power steering ... read more

Speak Up: Talking with Your John's Automotive Care Service Advisor

About 80% of the vehicles on San Diego roads today are behind on their preventive maintenance schedules. That translates to about 160 million vehicles in the United States that aren't performing as well as they could be - thousands right here in CA. Some of the maintenance issues are minor. Others represent serious safety concerns. There are many reasons San Diego drivers neglect their routine car care. Some of the more common ones are complacency, lack of confidence, lack of trust and budget issues. Modern vehicles are amazingly reliable compared to their older counterparts. They can run for years without any repairs, and we sometimes translate that to mean they don't need any maintenance. The trouble is that without maintenance, parts in the vehicle are gradually wearing out, fluids are getting dirty, oil is developing sludge — a lot of stuff is happening that we can't see, and it is destroying the vehicle. The first time we learn there is a pr ... read more

Problems with Suspension Solved at John's Automotive Care in San Diego

A vehicle's suspension system is tough. It can last for years and after lots of driving for San Diego drivers. But it can be damaged quickly by hitting a pothole, curb or rock, and it can wear more quickly if you frequently drive off-road or on bumpy roads. A workhorse vehicle — one that hauls heavy loads — is also going to be hard on its suspension system.Because the useful life of your suspension system contains these elements of unpredictability, it is important for San Diego drivers to have them inspected periodically. Worn, broken and missing parts can be identified during an inspection at John's Automotive Care . An ineffective suspension system will decrease the driver's control over a vehicle, so when it is damaged it frequently leads to the worst kind of vehicular damage — dangerous accidents.The suspension system is composed of springs and shock absorbers (or shocks). Springs suspend the weight of the vehicle above its axles. They allow the vehicle to ... read more
