I spoke to Paul, the 14' diameter is 'default' if the car is measured as 'missing data'. He assures me the cameras 'scale' the wheels diameter automatically in this mode or it can be set manually. Nevertheless when you go back for the tyres the car will be re-measured to give you peace of mind. Typical friendly conversation with Paul and he understood why you felt unhappy with printout. Let us know how things go Thanks Tony, Its much appreciated that you spoke to Paul, I am sure everything will be fine. The service at Dury lane was excellent and I would be happy to recommend them, my last alignment done at the local tyre fitters was a mess so I am sure you appreciate my concerns Thanks on some excellent advice and congratulations on an excellent website that has given me a good insight into the black art of car alignment! Will let you know how it goes

Feel free to mention wim and our conversation, Paul ownes the centre if possible talk to him. This is a simple operator error but damaging if not addressed. Paul has my number but if you have any immediate needs contact me at work 01923 234666 and i will assist! Hi Tony, I spoke to paul this morning, who said that although the printout said 14" the machine will have been set to 18". Is this possible? thanks Chris Unlikely.... since the machine did not hold the data for your car on disc, then the data would have been input as 'missing'.... the machine then will set to default and require the cars dimensions as mentioned before.... 14" is the default......... if the printout displays 'before and after' measurements then i feel this is based on the visible wheel diameter... Tony Thanks for the reply, The printout displays Diagnosis and Adjustment (before and after) but no nominal values (because the settings were not on file I presume) The mesurements were not way out +2.9 on LF +0.3 on RF adjusted to +70 on each (at my request) rears were -2.5 RR and -0.30 LR adjusted to +1 on each Paul did say that the machine automatically will detect the wheel size, and adjust accordingly, I have two new front tires that he is going to fit for me on Wednesday. Should I demand a re-alignment? I dont want to cause a fuss, as he has been helpful. And i need a reliable alignment guy! Would it be possible for you to give him a bell tomorrow, and let me know what he said? Many thanks Chris

Hi Tony, I have no problems contacting the Center on Monday, They were very polite and helpful. And as we all know mistakes do happen. If you dont mind i will mention that i have discussed this with you and you have advised I need a re-align with the correct wheel diameter. (Do they need to know anything else)? I will let you know, if i have any problems but i am sure everyhting will be fine. Many Thanks

Yes it will... All machines require and image of the car in 3D so that the cameras can place themselves in a Horizontal, Longitudinal and Vertical plane, the wheel Diameter, wheel width and track form this image. In short the Geometry and any corrections were worthless................ sorry. Hi Tony, Thanks for the reply, the unit seemed to be just a 4 wheel laser alignment system, would this still make a difference, as the arms with the lasers on didnt seem adjustable (Sorry about my limited knowlede on the whole alignment can of worms!) This alignment was done at one of the trusted center`s on your site, I pressume i can call them and ask them to realign with the correct wheel diameter FOC? Are the readings likely to be out by much? IS the car still ok to drive? Thanks Chris

Hi, I have just had an alignment done using a Pro-Align SPACE 800, I gave the mechanic the required specs for the vehicle (350z) as the machine did not have the car in its database. After getting my printout i have noticed that the Rim Diam is down as 14" where as my car has 18" wheels Will this make a difference to the measurements taken? all readings on the sheet are in degrees and minutes, apart from the toe which is in mm. Thanks MrRoper
