Paul H Posted August 31, 2020 Report Share Posted August 31, 2020 Here’s a pic of the offside front tyre on my Vitesse . The near side tyre has no apparent wear. Mileage approx 4K Is this wear on the outer edge due to excessive Toe In or Toe Out ? Thanks in advance Paul Link to comment Share on other sites More sharing options...
johny Posted August 31, 2020 Report Share Posted August 31, 2020 If it was tracking alignment I would expect both tyres to have worn as to go in a straight line both wheels have to have the same angle even though it might be the wrong angle. To have wear on one tyre only sounds like heavy cornering on that side or another type of misalignment on that wheel only.... 1 Link to comment Share on other sites More sharing options...
Clive Posted August 31, 2020 Report Share Posted August 31, 2020 I wonder if it is affected by rear wheel alignment? But easy enough to check. The gunsons trackrite or bits of wood and a tape measure. And string. String is good.. 1 Link to comment Share on other sites More sharing options...
Nick Jones Posted August 31, 2020 Report Share Posted August 31, 2020 Wear like that on the outside edge would be caused by excessive toe-in, but as Johnny says, normally affects both front tyres fairly equally Nick 1 Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 31, 2020 Report Share Posted August 31, 2020 the effect of road camber makes the side slip wear one tyre more than the other its not uncommon it is affected by how square the rear toe is reacting ,which changes the forces along the centre line of the car you do also need to check the rack backstop to TRE centre is equal on the n/s and o/s rods or toe out on turns is very affected trakrite makes a economical and simple one man check of toe/sideslip ( about £45 amazon) search toe in the simple way on here , for the two planks and a tape measure and to get the rear toe square just place 6ft of straight timber against the rear tyre and sight its run to the cars sill , both sides should be visually similar | | not | / respect the spec which calls for 150 lbs on each seat to set the staic ride height or you waste your time , so get rent a crowd to sit in Pete 1 Link to comment Share on other sites More sharing options...

Pete Lewis Posted September 1, 2020 Report Share Posted September 1, 2020 well yes the toe spec in the vitesse WSM is static loaded this just sets the wishbones and god nows what in its average running position , the toe changes as the load and ride undulations happen so static is the midpoint .of all the ups downs and rolling get some bags of compost so the mrs can use it afterwards ha ! i could bring my kit to duxford and do checks but rent a crowd 6ft apart may be difficult ... needs a roof rack ???? edit the GT6 WSM gives some unladen specs , need to print these out as theres around 2-3 mm difference , which is exactly why setting to a static spec when unladen just gives you tyre wear , just what you will get from any tyre place who dont have the correct specification you pay to have it reset then return in a year as youve scrubbed the tyre out diy and get it right its easy Pete Link to comment Share on other sites More sharing options...
Paul H Posted September 22, 2020 Author Report Share Posted September 22, 2020 Purchased the Gunson Tracrite From previous comments I was expecting excessive Toe In This turned out to be correct Jack up the wheel loosen the track rod with 3/4 AF holding the track rod in place with a 5/8 AF . Add tape to show how much movement you have made . Slacken off steering rack gaiter 2.5 turns and tighten up , settle and retest Now within tolerance Thanks for input Paul 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted September 22, 2020 Report Share Posted September 22, 2020 no need to jack her up but its best if you have a passenger in at the time back to the olde 150lbs on each seat mode so stick a passenger in and see if it needs a small change if you drop the trakrite all the plastic rollers popout and the needle becomes un hitched , but a bit of head scratch and a cuppa and it all springs back together if it gets over stroked the needle will disengage , you will see its a shaped washer that needs to be slid in place on the tyre board it might take a few goes to win but a cheap and easy bit of kit will save you £££s of tyre wear # whats the back like ???? rear toe errors will make it bunny hope on pot holes etc Pete 1 Link to comment Share on other sites More sharing options...

Mjit Posted September 22, 2020 Report Share Posted September 22, 2020 I have to say my Trakrite sits on the same dusty shelf as my Clickadjust. Buggered if I could get it to tell me anything but maybe I should give it another go some time. Link to comment Share on other sites More sharing options...
