• Tramlining ? Someone is trying to sell something old , but with a shiny new name . That’s what tire “ tramlining” means . I’m certain there’s a tire company somewhere that’s going to sell you four new tires , or you will probably need four tires , and of course , unless your really broke , it’s Wise to have them set your Toe Adjustment after checking the front end suspension / steering for broken / worn out parts , and If you go to any big brand named Firestone , or Goodyear stores , They’re going to probably have several different people looking for any reason to point out a problem with a suspension component using terms Like “Tramlining” , and your gonna be like “ Ooh my , ‘Tramlining’ . Sounds important . I better get one of them .” It’s just another Grabble using words , and just as certain , and as quick as You all started donning those darn coronu muzzles , you will pay these guys , these wolves , these salesman , and they must sell people Tires , and services that they need so that they can eat . They get a commission , and if They’re hungry enough , or just psychopathic enough they’ll Lie , and sometimes just for fun , to see how far they can take it with you , and see if they can get you looking under your seats for seventeen more cents , like some crack head , to pay up your bill in full . The majority of the Mechanics out there are moral guys , at car dealerships they are ethical , and competent , but in those high pressure selling shops there are often young , inexperienced , and often this leads to them either being easily swayed to ‘go along’ with the salesman who is their Boss , and them ‘faking’ adjusting alignment angles on your car . They may be under there LARPing it up big time , but they ain’t doing much else . Feigning as though they’re adjusting your front end angles , today a front end alignment consists of measuring where all of the front end geometry angles are at in relation to the weight of the car , and these are checked , even though caster and camber may not be adjustable , if one of the angles is way off , it will indicate somewhere something is ‘bent’ . After checking the caster camber , and Steering Axis Inclination angles , last thing is adjusting the toe - in , or toe out , depending on the specific car’s manufactured recommended toe angle setting . with few exceptions setting the toe angle will be the only adjustment , and it is critical that it is correct , or your tires are going to be quickly destroyed .A couple exceptions that require other adjustment while front end - END - alignments are done may be if your car, or truck was in a collision , damaged , or bent a suspension part from hitting a pothole , or has frame sagging from being over twenty years old . , the Caster and Camber should not change too much , or not enough to matter , and not require adjusting , but I assure you , you will be charged for checking it , as if there’s an option not too . Most Vehicles today only have toe adjustments . So when - you get charged $400.00 for a four wheel Alignment , you better look at what the Kid is doing under there, and if He’s not at each of the wheels , and spending at least ten minutes at the adjustment per four wheels after your Car is all set up with the measuring system , and He has found the correct information etc . Ninety nine percent of the time , unless you own a new car , these adjustments are frozen , and will take longer than ten minutes each to get to move so the adjustments can be made., So up to two hours of the Mechanic doing stuff , not walking around telling jokes to the other Guys , and if he is doing that , and he points at you and laughs while talking to another Mechanic , well , you can assume very safely that you are just another ‘mark’ , or just another victim of their Tire Grabble ..
  - O.K. where was I then , ‘ tramlining ‘ . We used to call it ‘bump steer’ . Your tires have a natural tendency to follow trolley car tracks that are in the roads where trolley cars ride among the automobiles . When Bias - Ply tires were still in use this was a big problem because being much stiffer by the virtue of inherent bias ply tire attributes because of what they were made from , and how they were made from the necessary design using these materials added to these bias ply hazardous attributes also . You all know that feeling of driving over a train track rut , and it takes your car along the track , and likes to stay there , well bias ply tires used to get sucked in , ride along the track about ten feet , and then your car would not want to ride along the entire time with the track , but after about ten feet it would send your car's tires / wheels jumping from , or bouncing out from it’s track rut , but it felt more like the front , or rear axle was being thrown into the opposite Lane of Traffic . Never did they both jump in or out of the tracks rut together though . Bias Ply Tires were so susceptible to this characteristic Tramlining characteristic that they would weave along , and pull your steering along cracks in the road even , It was truly not a sweet Ride .
  - But then in around 1970 or so , certainly by 1975 , but not entirely dominating the tire scene until 1979 came Radial Tires , and the experience of Driving a car finally was a pleasure , not a chore . But that’s another Chapter . I think I helped you define and understand what Tramlining refers to , and how not to be taken advantage of by salesmen at unethical tire Shops … Of course there is a lot more theory involved in front end geometry that no one cares to learn about today , and I’m not interested in typing all
  that crap in here only to have no one read it , but if anyone desires to understand Caster , SAI , and Camber , etc. I ‘ll type it if you are interested . not now though..
