Hi Folks,

I have a GLA45 and I seem to be chewing up the outside edges of my tires. I had an alignment done just before swapping over to my brand new winter tires and noticed they were also getting chewed up. I now have a brand new set of Pilot Sports on the car and will keep an eye on them. Is this something that the GLA45 just does?

Thanks,
Ed

 

This is probably a silly question but are you keeping your tires properly inflated> Tires low on air will get chewed on the outer edges like you're describing. You can check the MB recommended tire pressures on the drivers side door sill.

 

Not a silly question at all.. The answer is yes, I check them weekly and top them off as needed.

The alignment chart the dealer gave me had all four corners green. The winter tires were on for maybe 2,000 miles max and you can absolutely see where the outer edges are getting worn away. I am about to do a 3000 mile trip to the east coast and back. I will take some before and after pictures of each wheel..

Make sure you check your tire pressures before you drive the car on a particular day. You won't get accurate readings if you check your tire pressures after the car has been driven.

 

Do point out the fact / reality that when you are reassuringly told “will carry out a Full Front and Rear Wheel Alignment” ... all that can be altered is only Front and Rear Toe (directional) adjustment:

On completion followed up by the statement (because of broad alignment parameters ) ... “is now within factory specs”. Frustrated with the need then to go from one dealer or alignment shop to the next - or continually changing tire brands.

Situation has come about through cost cutting and the ever increasing speed of auto assembly lines.

There is no longer Camber, Caster to adjust tire contact angles. Spread load more evenly.

KMAC has specialized in resolving such OEM suspension short comings since 1964 !

Front and Rear kits providing “ongoing” adjustment to cater for other then showroom height conditions.

High cambered roads, altered height through load carrying or lowering, fitting wide profile tires, curb knock damage.

Hi @K-Mac

Thanks for the promo, I might actually do that if I destroy another set of tires on this trip...
