To many Wheel Alignment mobs today give Excessive toe in on the front wheels (just in case if the car has the Railway line issue and THEY DON"T WANT YOU TO GO BACK WHINGING, TIME = $$$$$) thus wearing your tyre's out to quick. Trust Me! If you had money to waste do this.
Book your car into 10 Wheel Alignment places over 2 to 3 days and take your car to all of them and you will notice that all of them will adjust your wheel alignment and since this is the case that 90% of them will do this which one of them gave your car the best alignment?.
I Tell you this The best Wheel Alignment I've ever had was done by me using a Flat concrete driveway, Brick layers String, two car stands, a accurate Spirit Level, and two steel rulers one 150MM and the other 300MM. Do a Google and a Youtube on how its done. I hate having a steering wheel that is not in the correct position whilst driving on a Flat straight road (aca Brisbane to gold coast Hwy) and you will have this issue 50% of the time after you have paid some company mega dollars to give your car a wheel alignment.
For me the Least amount of toe in the better as you will find your front tyre's lasting a lot longer, Plus How many of you have a Compressor in your garage with Air Points around the garage for easy to put air in your tyre's if needed. I check my Tyre's pressures every Fortnight or if i'm slack every 3 weeks.
I'll tell you what the problem is....Finding a place and or person, that knows how to read tyre wear patterns and how to adjust the alignment settings, according to the wear patterns on the tyre. Granted, this can be done at home with your methods, but by grouping every aligner in the same boat is wrong.
Yeah, you can go on you-tube and learn how to adjust the alignment settings, but you-tube can't teach you how to read wear patterns and adjust the specific alignment settings to maximise the wear of a tyre and you-tube can't teach you how to make the judgement call on how each and every specific driver drives their car so minute adjustments can be made, so the tyre wear pattern is correct.
A straight steering wheel on every road surface you might travel on, is impossible to achieve, because every road has a varying amount of camber to it, which effects how the steering wheel is positioned, to keep the car straight. The workshop I work at, the road camber varies enough to offset the steering wheel to the right by 1 degree, which would be enough to annoy you, with what you have written and is impossible to have it 100% to your liking .
Yes granted there are alot of "cowboy" aligners out there that look at a computer screen, adjust so the settings are in the green, meaning the settings are what some person has put as being in specific allowable range on a computer program, but have no idea on reading a tyre wear pattern and making those minute adjustments correctly to prevent irregular wear you mention.....
Tyre pressures....Yes, they effect alignment settings a little bit.....But tyre pressures will cause uneven wear on either both edges, or the centre of the tyre.....Incorrect alignment settings will effect just 1 edge of a tyre. So tyre pressures is another area, which is driver style and car specific, not something you-tube can teach you
So you-tube isn't the answer...Experience is.....and this is coming from a knob that deals with these issues all day every day and you-tube "experts" that live in their own little world...
