daverclasper Posted July 8, 2020 Report Share Posted July 8, 2020 Hi. Had some new boots fitted by Pro Tyre and a geometry check. This was done unladen. The toe in is 16mm, (left 7.7mm, Right 8.3mm, whatever that means?). I will have a go at setting it myself, using Pete's D.I.Y method, though as the above figure seems way excessive, is there anything I should look at, to see what may have caused this please?. Cheers, Dave Link to comment Share on other sites More sharing options...
Nigel Clark Posted July 8, 2020 Report Share Posted July 8, 2020 The official workshop manual states front toe in for the Vitesse 1/16th to 1/8th inch. or 1.6 to 3.2mm. The toe in measurements on your car do sound excessive, were the old tyres wearing unevenly? With so much toe in the outside edges would probably wear faster than the rest of the tyre.

Pete Lewis Posted July 8, 2020 Report Share Posted July 8, 2020 at 16mm you would scrub the tread very quickly toe dimensions in inches or mm is rarely backed up by at what diameter the rim or the tyre periphery ie 3 mm at the rim is more than 6mm at the tyre setting parallel eliminates this conundrum , you do need the car at static heights to use the triumph specifications , some GT6 manuals give the unladen figures i would get 150 lbs on the seats (or rent a crowd) and use the twiddle day bars and tape set to 0 to under 3mm toe in for radials at the tyre wall !!!! the trackrite eg https://www.amazon.co.uk/Gunson-G4008-Trakrite-Wheel-Alignment/dp/B0012M9KEC/ref=sr_1_2?dchild=1&keywords=trackrite&qid=1594229152&s=kids&sr=1-2-catcorr and set for zero side slip tyre pro had no spec to work to and probably have not had the equipment calibrated , this sells tyres you been to twiddle day ...get your tape measure out search toe in the simple way on here with 16mm toe your tyres would be bald on one edge in a season Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted July 9, 2020 Report Share Posted July 9, 2020 go back to school and get yout trig book out and dream triangles if you know the toe in and at what diameter its at you can work out you have the hypotenuse and adjacent the opposite is the distance the toe scrub drags the tyres sideways 3mm toe gives around 20' angle at a diameter of tyre wall 24"or more project your toe to 5280 ft. (a mile )or a KM and you can see and you see 3mm toe actually drags the tyre sideways a horrific distance thats why its the most aggressive tread remover over any other geometry errors that do not cause serious wear anything like toe problems do.

Mad4classics Posted July 9, 2020 Report Share Posted July 9, 2020 Has anyone tried one of the Track Ace wheel alignment tools?; bit more than trackrite, but sounds pretty good for a tempting price. David Track Ace Link to comment Share on other sites More sharing options...

Pete Lewis Posted July 9, 2020 Report Share Posted July 9, 2020 i have a track ace ,, its simple concept but a nightmare of the bars keep falling over the projected red spot is never easy to get in the mirror and bounce back to the screen youre on youre hands and knees more than youre sanity will survive so its up in the shelf dust , track rite is just so simple flat floor drive over get the reading I often take mine to the pub and shock many with their scrub I did have a old Humber experimental dept optical set which again is complicated to set up I gave it to Kevin dont know if he fired it up Trakrite Trackright so simple so right and less than a price of a tyre , if you drop it all the rollers pop out and the needle disengages but its easy to re assemble if you have a clumsy epi Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted July 9, 2020 Report Share Posted July 9, 2020 i got mine in a trial before it was fully released , i have years of experience with all manner of gear and initial with little else around i gave it thumbs up side slip plates have been around for years I had a Weaver one weight was just about portable , but more aimed at truck so brick sh1thouse design the trackrite is a light weight but ideal for DIY yes it only slides on nylon straw rollers but it works so simple and lightweight one handed job someone in the past thought you need two one for each wheel that would not work one tyre has to be on the deck to find the slip reaction if you get fussy the slip could be halved but set to zero they are parallel and takes 30 seconds to do a test , not 30 mins of faffing about you still need the load static ride heights specs unless you have a unladen figure , but as you best to drive over you just need a passenger Pete Link to comment Share on other sites More sharing options...
