Run flat tires

Indeed. I am shocked and happy at the same time as it likely means tbe cause is now determined. The printout I received show toe specs 0.05 - 0.12 for some reason.

I emailed and spoke to the mechanic who just did my alignment yesterday explained that I need piece of mind at 0.01 at all 4 wheels. Asked for new rear alignment bolts to replace my ceased bolts. He is cool, ordered the bolts and once he changes them (I will have to pay obviously) he will realign for free to the values I asked for... pheww. Now wonder how much those bolts will be)))

The car feels so quiet on a good road.. almost silent. Different kind of experience. So much more enjoyable. My new Continental Sports non RF are quiet huray!

very cool

If the mechanic is a worker at the shop, Id hand him 10 bucks, say "I really appreciate your help" or "thanks for putting up with me, it is really appreciated". If he is the owner, offer to give him a great review on yelp or wherever he wants.

Shops get the crap kicked out of them with the new online world, when they do something right, it should be acknowledged. A smart owner will recognize that an authentic review is worth a lot



Oh, to put a fork in it (alignments that is)...many times people will say 'car doesnt pull, so the alignment is fine'. Nope! Whiles yours had obvious wear signs, there really is no way other than putting it on the rack.

Great points ard re human factor and reviews. I think my guy is at least a limited partner (only him and the owner price jobs) - he was the first employee 20+ years ago since the shop opened doors. He drives a 997 4s as his summer car but money never hurt) I will hand him CAD 20 but expect him to adamantly reject it, I will try though!

Online reviews - I am all over it these days! Dont want to rush) i will give it a week or so to see that my struts still in place and they actually get all 4 wheels to the desired 0.01 or at least closer to that.

My previous alignment shop Midas already has 1 star google review, the images of my unevenly worn tires and the screen images showing front toe that is 500%+ off! The interesting fact is the that Midas' owner is a retired mechanic (from GM) and I had 0 doubts trusting him my car and his guys xompletely screwed it up. Personalities and attitudes towards quality, customer, etc. make ALL the difference.

I haven't checked the pressures hot. Maximum inflation pressure is 50psi.
I don't think I'd be exceeding this. Good point though, next time I do a good run I'll check.
Fuel economy, I imagine would be better. Less resistance.
Most of my highway work is towing. Last trip I averaged 12.3l/100
Doing a constant 110km/hour. This is pulling a touch over 1.6tonnes

Thanks Chris, I recall my Acura showing higher (vs stationary) pressure while moving, especially highway speeds. Also in the fast turnz, the outaide wheels were additional 1-3% higher pressure as far as I recall.

I used to run higher pressures, often at the stated limit. I probably got better gas milage and possibly tire wear. But it was at the cost of handling and comfort. At maximum pressure the contact patch is reduced resulting in less breaking and cornering limits and of course ride. I am willing to sacrifice wear for cornering and breaking.

Thanks Tomaz. You mean pumping them cold to the stated limit?

Yes, I don't do that anymore.

***Update***
Just had Rear Tie Rod Bolts and Washers replaced to enable more precise alignment. 4 wheel alignment redone to smaller toes o all wheels. I witnessed how not easy it is to get a precise value to two decimal points. I ended up with 0.01 for both fronts which changed to Front Left 0.00 and Front Right 0.02 while he presses print button. In the rear I now have negative toe of -0.03 Rear Left and -0.01 Rear Right.

However, what surprised me more is that its only been a 1,000km since my last alignment a month ago and my front alignment numbers moved by 0.05 and 0.02 I know because I compared todays pre-work numbers on the screen (0.10 and 0.07) to the last print out of 0.05 for bothfront wheels. Big movement. The mechanic said its normal and will always change. This means in a couple of weeks my numbers will be slightly different. Sounds like regular procedure.

You mean toe in, correct?????

My rear tires now show small negative numbers, as opposed to being small positive numbers. The goal was to get to positive 0.01 on all 4 wheels, but I ended up with a negative sign on the rears. I am not sure if the negative toe in is still a toe in or it is called toe out.
