I installed Eibachs earlier this year and I had the car in the shop today so I wanted to check wear on the tires.

The fronts look fine, and when I was checking the rears I was looking at the inside edge for wear and noticed the passenger side had some wear but then upon looking closer I noticed that the whole tire is worn from edge to edge more than the driver's side.

The tech thought maybe it is due to the LSD and allowing that side to spin more than the dirver's side.

Anyone see this on theirs.

 

Only tire feathering issue was my front right wheel. All my other wheels were fine.

 

Im eating up my rears pretty fast compared to my fronts.
Been having too much fun!

 

What type of tires are you running and how many miles? It could be a bad build compound on the right rear tire, or you have more spinning with that tire, or it might indicate a issue related to the tire/suspension mods.

Will Nissan address these concerns with a Z that has suspension mods?

 

I have Toyo T1S tires. I was checking for unsual wear due to the lowering but as I said the wear is even across the whole rear passenger side tire which doesn't look odd until you compare to the driver's side and it has more tread.

Since the wear is even I don't think it is due to suspension, so that's why the LSD was suggested, not sure which wheel spins more.

I haven't had an issue for tire problems other than this but I would think that if the alignment specs are within limits and you have problems with a lowered car they would take care of it, then again I think it would depend on the dealer and how much they want to work with you.
