Average life tires should get on a G35 Coupe?
Seems like I've only had mine for 10k miles and they're balding pretty bad.
Oddly enough, they're not balding evenly.
Right rear tire is balding in the middle, while left rear isn't that bad.
Suggestions? Am I looking at a problem?
Solution before I purchase 20 inch Asanti's and new tires?

 

quit doing burnouts!!! or donuts!! haha jk..i have no idea what to tell you

 

Camber kit and then do a 4-wheel alignment. specs specs should be at 0 to -1. The factory is at -4 and varies from there. Get your wheels balanced and hope for the best.

Try Nitto NeoGenz tires. there are made for car with horrible camber issues. And helps the tire wear out evenly.

 

^^^Hopefully my next tire when my SportMaxx wear out. Maybe by then they'll have 20's. With my current drop, I'm -2.x camber. Interesting...usually they wear on the insides from oem negative camber.
Wear in the middle usually indicates over inflation of tire.
Tire Rack good place to research tires. Gives wear rating numbers. Higher the number, longer they last.
KDW2's have a rating of 300 I think. Highest I've seen for ultimate high performance ZR tires, but my set of KDW2's were noiser than my Dunlops currently.
When you decide and get, highly recommend a 4 wheel alignment same day or soon afterwards.

 

The life of tread [where the wear index number comes from] is a on the road test where the wear get extrapolated from 7,200 miles.

Testing for this category is performed on a 400 mile test course near San
Angelo, TX , USA. A group of not more than four test vehicles travel the
course in a convoy so that all tires experience the same conditions. Tread
depths are measured every 800 miles. The same procedure is done for a set of control tires. After 7,200 miles results are compared and the test tires are
assigned a rating.

Unfortunately these tire test convoys are driven in a slow and non accelerative manner so they always over estimate the life if you drive faster than speed limits or accelerate faster than a snail or brake without the egg under the pedal.

Streets and road rough have a serious impact on tread life especailly in warm summer conditions.

Ultra high performance tires are stressed to achieve these levels of enhanced performance and as such they should be replaced at 20,000 miles to avoid the exponential increases in failures that occur ofter 2 years.

 

Factory camber is NOT -4... yur crazy, -4 camber is a ridiculous amount. A stock height G35 has camber ranging from -.8 to -1.2 in the front and -.8 to -1.6 in the rear.

Neo Gen tires help with negative camber, but they are also asymmetrical which means they can NOT be flipped. You can get the same life out of a tire by flipping it from one side to another when the first inside wears out.

Alright, what is a camber kit, and where may I purchase one?
Thank you

 

One problem many non engineers overlook is that while a camber kit can fix the camber sitting still so the alignment APPEARS CORRECT............lowering even with camber kits changes the point on the camber gain curve.

A bump steer kit is needed to avoid serious toe problems as the body rolls and changes position in a lowered vehicle.

Invariably lowering even with kits causes many serious problems that degrade tire life!

 

i think the one that that decreases tire life the most after we lower our cars is the fact that we know the car is lower and on stiffer springs so we turn harder during our daily drives.
