So I have an 05 coupe, completely stock. But the front tires are wearing on the inside a LOT. I mean literally the rears are at 70%, the front outside edge is at 80%+, but the front inside edge of the tires is probably <10%. I tried searching, and this doesnt seem to be a common problem. I am running Toyo T1r's on stock oem sizes. Because there is no camber adjustment for the front, what could the issue be?

 

The issue is toe and tire rotations. These cars, especially the lower coupe and Z, have very aggressive alignment (caster, toe, camber) settings. With these cars, you need to do the following:

1) Only buy asymetrical tires. Directional tires have a tendency to exhibit higher wear on the inner shoulders, especially in the front because of the toe. Asymetrical tires will allow you to cross rotate correctly.

2) Cross rotate the front and rear tires every 2000-2500 miles.

3) Set front toe to maximum toe-in (0.16" total) to combat the inner wear, feathering and noise.

4) Did I mention rotating the tires every 2000-2500 miles?

 

He's got a coupe... should have staggered wheels, how would he cross rotate? Great suggestions for a non staggered wheel setup tho

 

i had the same problem with mine and the only way i found to correct that was to get a camber kit cause the g's don't have any camber adjustments at all

 

the nominal spec for front toe is .05 degrees. toe out. that much toe in will make for a sluggish steering feel.

 

If performance tires last 1-2 years that means 60-30 sets of tires and 60-120 paid alignments during your driving life....................that's about $60,000 in expenses.

One should become educated and very knowledgable in tires and alignments.

One will spend $600,000++ in vehicle expenses, insurance and gasoline during that period.

The point is a few hours per week or 10 per month or 100 hours per year in transport education should be very cost beneficial!
