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

  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

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.

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.

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

  Hey San Diego area drivers, are your tires worn out? What is the standard for our CA streets? How can you tell on your vehicle?While there may be legal requirements for the San Diego area, there are safety concerns that go beyond meeting minimum replacement mandates.Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently.We're referring to the tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.A car and a full-sized pick-up accelerated to ... read more
