Well we told you there were a lot of tire myths and we only have four we are covering.
Myth: I don’t need winter specific tires
So lets see here, you don’t want to by winter tires but you know the snow is coming what do you do? Well some of us will go find a set of all season tires and hope for the best, thinking well these are a good deal I can use them a couple more years. Well if you live in the northern states that may not be the best idea. Snow tires have a lot to offer to those that drive in the snow. First being a tread pattern designed specifically for maximizing traction in the snow. Next they also have a much softer compound so they grip better on hard packed snow. And in some places you can even run studded tire which will bite into the ice. You just won’t get that out of all season tires. While there are places that see no more than a few inches a year where it would be pointless to spend the money on winter tires. Remember a set of winter tires will be cheaper than getting into a wreck because you lost traction.
Myth: A bump in the side of the tire is a defect
Well this is not true, this is where the belts in the tire come back together and over lap. Nearly every tire has this spot and if you look for tires with out it you may never end up buying tires. While some think this may be a weak spot it is actually the strongest part of the tire. There are also some tire manufacturers that are offering tires built differently that have no over lap because the way the materials are put into the tire.
Well this is the last of our tire myths, although there are plenty more out there. We are moving on to our next subjects. If you have questions about tires and we didn’t cover it just contact us on out contact page, or on Facebook.
Myth: Electronic Turbos:
So one of Ebay’s favorite car scams is the electronic turbo. Which always seems like an enticing offer. I mean who wouldn’t want to boost their horse power by 50% for 30 bucks. We like they say if its to good to be true it probably is. With everyone one of them claiming not to be like the other guys and making real horse power, they all seem to be real right? No, sorry to bust your bubble folks. There is no way a fan will create boost. While a fan in the tube will move air, it will not overcome the vacuum of the engine. And in most cases they restrict the air flow and cost you power. When you look at how a turbo or any forced induction works, you will realize that turbos compress the the air. As air comes in the inlet and moves towards the outlet the area in which it compresses gets smaller making the air more dense. Also turbos spin at tens of thousands of rpm, you simply will not get that out of a fan in a tube.
There are a few applications of electronic forced induction kits. These have huge motor’s typicality mounted to a real turbo or super charger, and powered by many 12 volt batteries. Meaning they need more than a couple wires and a computer fan. While I have toyed with the notion of developing my own version of this, and have designed the entire device, car batteries are just not at the point yet to support the draw that one would require.
We will be like our other myths, covering forced induction in full in the coming weeks.

Also We are now on Pinterest, although I haven’t quite figured that one out yet.
Myths are wrapped around the car world just as much as the truths. This week and maybe even into the next we are going to debunk a few for you so you may be a little more informed. Some of these myths come from good reasoning but with bad follow through, kind of like my golf swing. Typically they start from a lack of knowledge or to much from the industries for fathers who are set in their ways.
So lets get started.
The lower my car is and the harder the springs the better the handling.
This is one is one of the ones that comes with good reason, that lower centers of gravity the better the car will corner and harder springs will reduce body role. Yes this true, to a point, as there is a threshold that the car needs to reside in. What that means is when the car is lowered to much it will adversely affect the suspension geometry and cause things like bump steer. What is bump steer you may be wondering, well, bump steer in its simplest form is when the car will steer itself when the control arm goes up or down. We will cover that more later when we talk about total suspension systems. As well harder springs will help reduce how much the car “dives” into the corner on the outside, but that is job of the sway bar not the shock. When the spring is hard it will cause the tire to bounce more as it is the shock assemblies job is to keep the tire on the ground. Again we will cover this much more in the future.
Wings will make my car handle better.
This again s one that has perfect reasoning behind it but it’s only half the story. While spoilers will put down force on the back of the car it will take the force of the front, you know where the steering goes on, so you may now ponder how is this helping my handling. Well when coupled with a properly fitted front spliter which is basically a spoiler for the front of your car it will improve the over all down force of the car. It to has to be properly designed and fitted. Most cars you see in the circuits or Super Lap races have what can be referred to as Shopping Cart Wings. These optimize the air moving off the roof of the car by continuing it in a natural pattern off of the back of the car as a whole. One more thing to take into account is that to develop much down force at all you have to be traveling at a relatively high speed, or all they are doing is causing drag. As with what is above we will cover all the subjects in our myths fully begging in the next couple weeks.
