Front Tyre outer edge wear - any remedy?
(OP)
Hi all
I'm having a minibus with FAW of 3Tons (with 7.5 X 16 bias ply tyres). Its having a serious wear in front tyres outer edge (tyre outer Corners wears making feather like appearance). People say that its due to taking turns at High speeds & this issue is unavoidable & harmless. What do we call this type of tyre wear & what could be the reason? is there any way to rectify it?
Cheers

increasing negitive camber or toe out will reduce wear on the outer edges of the tire. If you have acess to a tire pyrometer you can do alignmnet changes and estimate the wear patterns all the same day. the hotter areas wear faster.

I assume that camber is negative? ie top of the tyre is in at the top? 1.5 degrees is a lot either way.

A pyrometer measures the temperature, typically race teams measure the tread temp across the tread, to determine their camber and toe settings.

It's not clear whether compliance in the front end will result in a slight amount of toe-out or toe-in under driving conditions. Nor whether it's front wheel drive.
It also crosses my mind that 7.50-16 might be a little on the smallish side for 6000 lbs.

I still think the "feather" would more likely be the result of a toe condition --- reverse ackerman? Negative caster? Just guesses on my part. Any good front end shop should be able to rectify your problems.
7.50-16 8 or 10 ply bias were used on most medium trucks in the U.S. as I recall. I had them on my 77 Dodge with a 9500gvw.

Also, since it's a beam axel, check for proper king pin inclination.
Bottom line---You need to visit a reputable front end shop that services TRUCKS! Your problem is not normal and may be the result of damage to the front suspension.
