Has anyone else had any experience of a lowered bus wrecking the outside edge of their front tyres. Our bus is lowered around 4" by cut and turn beam and has a slight rake to the bus, had the tracking laser checked at pro tyre so everything is fine, camber, tracking, everything is checked fine but after 6 months the outside 50mm of tread has been worn to the casing on both tyres. I'm thinking it has something to do with the suspension being wound round into its lowered position but would like anyone else's opnion before i spend £500 on drop spindles to get the suspension back to a more normal position.
I'd get someone else to check the tracking... There are loads of lowered cut and turn buses - had one myself - and they don't do this to the tyres. If you were nearer...
Had tracking set on my mates basic set up when tyres were fitted then took it to pro tyre to get it double checked on their super fandango laser machine, they did not charge me cos nothing needed adjustment. I expected the camber to be out but was fine. When turning from lock to lock does a lowered buses wheels lean out more at full lock than a standard ride height, i dont have another standard bus to compare too, this would explain the wear on outer edges and we use the bus daily so possibly seeing effects alot quicker than someone who only cruises at weekends.
who checked the camber and what did they use ? the usual tyre monkeys haven't got the gear or know how to check camber
The set up in Pro Tyre is as good as it gets, 4 wheel laser set up camber and everything, you get a printout of the facts and figures for your vehicle so i know its not the tracking or the camber when the wheels are pointing straight. The machine does the lot so operator error is ruled out.
Gonna start hitting myself over the head with the keyboard in a moment, the tracking was set at my mates garage, i then took it to pro tyre who ended up just verifying everything was well within tolerance, all 4 wheels to each other, the printout shows factory specs for your vehicle then what your vehicle in front of them has produced, all done in front of me by the head fitter. Tracking and camber all spot on when the wheels are straight.
What are the factory specs for camber the print out says? I dont know the factory specs myself but im sure someone can clarify what they should be and you can check this against your printout
Will have to dig the sheet out the glove box for figures. My thinking was along the lines of when you turn the steering the wheels start to lean out slightly and in my extreme lowered position the wheels lean more than normal hence rubbing the outside edge more than normal. Before i had it checked i was expecting the camber to be out but was fine, is the camber adjustable on a bus anyway.
check the air pressure. Then I would start again Get checked the baljoints wheel bearings and then the tracking/camber done again
dont believe a computer ,just because its says its ok .........i can plug a obd2 into a MODERN CAR ,shows no faults but i know the head gasket is gone !....this is a example ......do what people suggest as they are correct ......tracking ,ball joints etc etc ..get em checked by a vw garage or vw friend .....dont trust computer systems,or people that sell spinner hubcaps......or fat fingered mechanics........i do believe that tracking specs on modern machines are not correct with classic cars ,if that makes sense
Just been and checked my manual, and the camber angle should be -30' (minutes) which is 0.5° (negative camber angle)
