Hey guys, just put my winter wheels on and got some bad news. When I pulled my 18"s the rear inside is worn beyond belief. Totally shot tires. Front look like new. I never noticed the wear, due to the fact the car is lowered. My bad! I'm sure the H&R springs has something to do with this. What kind of problem is this? And how can I correct? I don't want to blaze thru my all season tires! Thanks in advance.

yah well then agian...

i worn my rear tires on the Nissan Pulsar quicker then the front (FWD N13)

THe culprit.. me pulling the ebrake to slide around turns..


Until the car was sold to a new owner, in which then i got an earfull on how the ebrake cable was too tight, and the drum shoes are badly worn and tires toasted.

just thought of sharing..

Jon, I did not rotate this summer. Total of 4k miles. I really think the springs are the culprit, any thoughts?

you probably adjusted your camber when you installed your springs. Did you go get your car aligned and re-adjust after the springs were installed?

Camber is definately the culprit. When you lowered your car did you notice on the rears if the tire had any lean to it?


The wheel would have looked like a backward slash. \

Wouldn't be that extreme but any kind of lean would cause the inside tire wear.

This also might help.

Yup too much camber. It's common when a car is lowered. Also 18" tires are more sensitive due to stiffer sidewalls.

Get the car aligned and reduce front and rear camber to get inside the factory spec. or at least as close as the adjustments will allow. You can also run a touch of toe in to even the wear.

Camber in itself shouldn't cause wear that quickly; it's probably a combination of things. I run -2 degrees camber and +1 mm toe on the back of my Porsche and the tires do not wear that quickly; I'll get 5000 miles + 4 track days before I swap the tires to the other side - and I have VERY soft tires (100 treadwear rating race compound)

A proper allignment from a specialty shop is called for here - you're not dealing with factory specs any longer since the car is lowered. Look for a specialty shop that services Porsches and BMW's and other European cars - they'll likely have someone that really knows how to run their alligment rack. If you'd like, I can ask for some recommendations from PCA members - there are a bunch in SW Ohio.

This is common problem the way to check it is if you jack the car up under the shock and see is there any play top and bottom of the wheel bye pushing in and pulling out if there is play the cross stays on the rear suspension this is the top suspension bar that links the hub to the sub frame

Wow, thanks guys, that sounds like the problem. My mechanic said an alignment was not needed at the time of install (poor judgement). If you can recommend a shop in the central Ohio area, that would be great. We don't have too many Euro specialists that I know of. Would the alignment suggest the proper camber adjust and would that be included? Thanks again, now I have to purchase 2 new summer performance tires for next year.
