Selecting New Tires and Wheels

Some of us San Diego drivers just love tires. All those little rubber hairs on new tires and the smell is wonderful. We live in a great time for tires. No matter how you drive around CA, where you want to go or the look you're after; there is a tire for you.The same is true about wheels. The hardest part is choosing from the thousands of wheels available at CA tire shops.The team at John's Automotive Care can help you get some things in mind before you make a purchase. Let's start with function and think about how you drive.For example, maybe you have a large SUV but you don't drive off-road around CA, so an off-road tread isn't important. Also, because you are not out bouncing over rocks in the CA backcountry, you don't need a high profile tire to protect your rims. So that means you can probably go with the low-wide look.If you have a winter season with rain and snow or if you find you need better ice and snow performance, they make great, high-performance snow tires that won't ... read more

Automotive Tips from John's Automotive Care: Rotor Problems

The brake rotor, or disc, is attached to your wheel. The brake pads rub on the rotor to slow your car when you are driving in San Diego.Rotors can warp, crack or become misaligned. They can also be damaged by worn out brake pads that scratch grooves into the surface. These conditions result in less contact surface for the brake pads, leaving you with reduced braking power.Over time and miles, rotors can also wear down below safe specifications. It is important for San Diego drivers to know that simply replacing brake pads on a wheel with a bad rotor will not solve the problem. Depending on their condition, rotors may be resurfaced or replaced.Brake noise or a pulsation in the brake pedal are signs of potential brake problems that should be addressed right away. If you have any brake concerns, please have your friendly and professional John's Automotive Care tech perform a thorough inspection.Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 9212061 ... read more

Time for Differential Service at John's Automotive Care?

Hello San Diego - let's talk differentials. If you have a rear-wheel drive vehicle, your differential is on the back axle. With front-wheel drive cars, the differential is up front. All-wheel drive and 4-wheel drive vehicles have three differentials - front, rear and in the middle. So you see, you've got a differential (or two or three) and it needs service now and then.What does your vehicle differential do? Well, it compensates for the differences in speed between your outer and inner wheels in a turn. Using the dimensions of a typical car, let's compare the distance the wheels travel from the start of a turn through to the completion of the turn.The inside wheel travels about 12.6 feet/3.8 meters. How much farther does the outside wheel travel? About 18.8 feet/5.7 meters – over 6 feet/1.9 meters more. This means the outer tire has to rotate 9 times in the same amount of time that the inner tire has to rotate only 6 times - so the ... read more

Smart San Diego Drivers Protect Against Overheating

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for San Diego drivers to prevent. The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine and then flows to the radiator. Air passing through cooling fans on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again. The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage. Different engines require different types of coolant/antifreeze. The owner's ... read more

Timing Belt Replacement in San Diego

Today we want to talk to San Diego drivers about timing belts. They're something that many drivers don't know much about and yet your vehicle won't run if it's broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner's manual, it's not the kind of thing that most San Diego area auto owners remember because it's not well understood.Let's review what a timing belt does. As most know, the engine's power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel, pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens ... read more

Getting the Right Tires and Wheels in San Diego

A lot of people get custom wheels in San Diego. When you do this yourself (over the internet . . .) you could run into trouble if you're not careful. Sometimes, once they're mounted, they just don't fit right. The tires rub in turns or on bumps. You don't want that. Consulting your John's Automotive Care tire professional can ensure you get the right fit. First he'll ask you a series of questions about your San Diego driving needs and what you want in your new wheels. Now, not every wheel can go on every car. Care must be taken so that tires and wheels are not too large or that the wheel is centered too far towards the outside or the inside so the tires rub.If you don't want to make any modifications to your vehicle, you would need to focus on the wheels that would fit. With trucks, some people in San Diego like much bigger tires so they need a suspension lift.Also, most San Diego drivers don't realize that you need to keep the rolling diameter ... read more

Super Slick at John's Automotive Care in San Diego: Synthetic Oil

When you get an oil change, it's always a safe bet to just use the type of oil the manufacturer recommends. But sometimes we're asked if we'd like conventional or synthetic motor oil. We glance at the price tags on the two options and choose the cheaper one. But in this case, the more expensive oil might be the better bargain for San Diego drivers. Conventional oil is made from petroleum. Its molecules form long hydrocarbon chains. Synthetic motor oil is either more highly refined petroleum or completely man-made. Its molecules are more uniform. This provides advantages over conventional motor oil. First of all, the molecular structure of synthetic motor oil makes it more slippery than conventional oil so it lubricates better. This translates to better wear protection for San Diego drivers, cooler operating temperatures and more engine power. Further, synthetic oil is more heat-resistant than conventional oil, and it doesn't vaporize ... read more

Relax When the Wind Blows in CA: Winter Car Prep for San Diego Drivers

When autumn comes around in San Diego, leaves fall, nights get longer and there's a definite nip in the air. Time to unpack the boots and gloves and fold some extra blankets onto the beds. It's also time for San Diego drivers to winterize their vehicles.Here is some expert auto advice for San Diego drivers on what vehicles need to keep everyone safe and rolling throughout the CA winter months.1. Check your antifreeze. Top it off or change it if necessary. You don't want your radiator, engine or hoses freezing up. If your vehicle isn't generating enough heat to keep you warm, your antifreeze might be low, or you might have a thermostat problem. Either way, you should get it checked out before the full force of CA winter sets in. If you are due for a cooling system service at John's Automotive Care in San Diego, get that done as well.2. Check your brakes. The slushy wet conditions of winter increase stopping distances. Ice exacerbates the problem. Your f ... read more
