TIRES

At John's Automotive Service we value the safety of our customers above all else. We want to ensure that you get to where you're going every time with a reliable and safe vehicle. A major problem area for the cars and trucks that come into John's Automotive Service, are tires. Your tires are your connection to the road, and without them doing their job properly, all the handling development and safety testing that went into your car may not keep you safe. Here is some basic information on your tires and how to know when the time has come for replacements.



Why are old or bad tires dangerous?

As stated above, your tires are an extremely important component of your car or truck. If you've ever been out of control in a vehicle, you'll know how scary being a powerless passenger inside a two ton metal box can be. Driving on tires that are too old, improperly inflated, out of balance, or not suited to weather conditions can spell disaster for your safe journey. Your tires were designed with a very specific task in mind. Using them improperly can have sudden and catastrophic consequences.



Signs your tires need air

This issue can be fairly simple to spot. If your tire seems to be wider at the part which contacts the road, they probably need to be topped up with air. Driving on under-inflated tires wears them out faster due to uneven pressure on the sidewall and can lead to full-on flats and even end up shredding the tire off the wheel! Low tire pressure ruins your vehicle's fuel economy. If you've ever ridden a bicycle with under-inflated tires you know how much extra effort you have to put in to get moving and stay rolling. On the flip side of this, driving with too much air in your tires is also unsafe. While it's unlikely that hitting a large pothole would cause the tire to burst (remember they're built to last for thousands of miles) having too much air pressure in a tire reduces the size of the contact patch, or the area where rubber meets road. This can lead to less grip and control over your vehicle. Every tire manufacturer prints the correct tire pressure on the side of their tires, so it's easy to find out the perfect pressure for your ride.



Signs your tires are out of tread

As with having over-inflated tires, a lack of tread can lead to less control and worse handling for your car or truck. Your tires' tread patterns help them to hold the road as well as channeling mud and water away from the areas that need to do the gripping. Without enough tread depth, your car can ride up on top of water on the road and cause you a complete loss of control. There are a few common methods of measuring tread depth, such as using a penny to gauge whether or not it's time to replace your tires, but we recommend coming into John's Automotive Service in Cedar Rapids, IA for a professional opinion on the matter. Not all tires are created equal and must be replaced at different times.



Signs your tires are damaged

Signs that your tires are damaged can come from a few sources. A visual inspection can catch potential problems before they become major issues such as nails or rocks embedded in the tread grooves. Always remember that there's a great deal of pressure contained within your tires. If you see any gashes, bubbles or hear the hiss of air escaping it's best to stay away from that tire and enlist the help of a professional. Believe us, you don't want a tire exploding anywhere near you.


You can sometimes feel tire damage while driving. If your car begins to make strange noises as it goes down the road or the handling suddenly becomes worse you should pull over as soon as it's safe. Driving on a flat is a bad idea, and can often lead to more severe damage to your vehicle.



What can and cannot be repaired

Tires are expensive and we take any opportunity we can to repair them safely and save you money. Small punctures can often be plugged and patched (it should always be both!) but sometimes the tire's day is done. If the puncture is on the outer edge of the tire (outside the tread) it's probably unsafe to repair. The same goes for a tire that's been driven on while flat. In this case the sidewall has become weakened and the tire is no longer safe. As with recommended pressures, each manufacturer has guides for what can and what can't be repaired.


At John's Automotive Service, customer safety is our number one priority. We hope you'll be a little safer with this information. If you'd like to talk about whether your tires may need inspection or replacement, call us at 319-396-4206 or visit us at 4910 Johnson Ave NW in Cedar Rapids, IA. Happy travels!

I do enjoy the rewards of being a car club member at John's Automotive! I actually left John"s Auto and I didn't have to get my card out to pay the bill. It was all covered by my Car Club membership. It pays to be loyal customer at John"s Automotive. I have received excellent care car!


-Peggy M.

I've been going to John's Automotive Service for about 5 years and have always been treated with respect. Bob, Al and the team do what repairs are required and do not try to up-sell you on things that are not needed. I do a lot of my own repair work, but I take it to John's when I need added expertise, special tools or just don't want to do it.


-Scott S.

The team at John's Automotive are knowledgeable, friendly and trustworthy. They always leave me feeling that they have my best interests at heart. Never fun to spend money on car repairs but it helps when you know you are getting value.


-Thomas G.

As always, John's Auto provided the quality service I have come to expect from them. They finish on time and in budget. I love the use of their loaner car as well. No upselling of additional services, but they will keep an eye on possible needs in the future.


-Josh W.

I absolutely love the people and service at John's Automotive Service. They are friendly, thorough, fair, and honest. They work around my schedule and always help to make sure I'm getting the best deal. They have an outstanding rewards program. I would highly recommend John's to anyone needing anything from minor to major repairs and service.


-Natalie I.

I can only give John's Automotive five stars for their service. They're knowledgeable, they are patient in explaining what and why I need work on my vehicle. They don't look at me or talk to me like I'm just a female, and not worth their time. They are people friendly, which is also important to me. Last fall they even went above and beyond 'the call of duty'. After they had finished working on my truck, I rode my recumbent trike to their shop to pickup the truck. I had just bought the transport rack and was still learning how to load the trike. They volunteered to help me get the trike loaded. As a matter of fact, one of the mechanics even helped adjust the rack to fit the trike better. Some places would just say ... To bad: it's your problem. Not the personnel at John's ... They wanted to make sure both I and my trike were safe. My father has been gone for years and my brothers and son do not live close. It is really nice to feel secure in the fact that I have mechanics who will give me good advice without taking advantage of me and at the same time, give me qualîty work that they stand behind. Thanks to all personnel at John's Automotive.
