Tyre Eating Problem

[paulh]

My 05 Gal goes through front tyres like they're going out of fashion. I keep them inflated at 38 psi (its a taxi so I always have different loads). Its always the edges of the tyres that go and its both edges of both tyres. I thought it could be the tracking but thats been checked by two different places and its fine. I was advised at its last test that the wishbone lower bushes were perishing, could this be the cause? Is there a way to check and adjust the camber?

Thanks

Both edges of both tyres suggests underinflation. I always use 44 psi and dont have the problem.

I agree ,more air required. I run at 45/46 psi all around for general use.

I think tyre pressures are manufacturer specific.

 

When I had Dunlops I ran at 41. I'm now running Michelin Pilot at 38 and have near perfect wear across the whole tyre.

you will find that cars that have power steering wear more on the inner/outer edges which can be more noticable the wider the tyre is, also if most of the driving is done around town. because our cars turn easier on the steering wheel we tend to over steer slightly which in turn scrubs the tyre a little hense the wear, you need to experiment a little with inflation pressure to try and balance it and consciously check your driving habits when cornering

being a taxi driver with all your running around ,cornering,U turns 3 point turns (or almost hand brake turn that i saw one do over weekend) ect ect it doesn't suprise me your wearing tyres quicker

 

 

Worn steering/suspension joints/bushes do add to the wear due to the movement it is giving so that does need addressing, also the way the tyre is made can contribute to wear some are soft compound and some are harder. obviously the softer ones wear quicker which from experience tends to be the cheaper ones (not all though). Also think about the centre point of the tyre that contacts the road as the pivot point, the wider the tyre is the more travel the outer/inner edges make thus more wear at this point.

 

The best I have experienced for wear were continentals they were a harder compound so lasted longer, the down side was you couldn't drive it too hard as it lost grip patic in the wet. the best I have had for grip were Michelin's but we are talking on a vw t4 van. that said though they were the same size as the Gal and x/load

I agree that both sides of both tyres suggests a combination of pressure and use. Certainly, you'd do well to start trying pressures in the mid-forties. Unfortunately, I can't comment on tyre brands as I use whatever is reasonably priced at the time and get 40-60K per set.

 

Personally, I try to avoid low profile tyres as being unnecessary, uncomfortable, excessively expensive and less durable but if that's what you have to fit the so be it.

 

Many drivers have developed a habit of turning the steering before starting to move. This is a sure way of trashing tyres but it is probably unavoidable if using it as a taxi.

The tyres are under inflated hence the wear, remember the recommended pressures are a minimum.

 

Also the tyre pressure is dependent upon the vehicle not the make or model of tyre, its the air pressure that the vehicle sits upon, this doesn't change if you use a different set of tyres.

 

And lastly as mentioned incorrect use of power steering ( when stationery ) will vastly reduce the life of your tyres.
