Unusual Tire Wear - Test
 

Just got my 86 serviced and the dealer noted with confusion that my front tires were significantly more worn than my rear. They had not been rotated. Who knows why? :)

Rear tires get changed much more frequently than the fronts ,and you have scrubbing from toe out for turn on response?

This is my final answer. Definitely am expecting increased wear from autocross usage - I know my fronts get hammered quick compared to the rears

Your alignment is off?

I suspect track or autoX use + possibly sub-optimal setup.

My car wears fronts WAY more quickly than rears at the track. But my setup is not optimal... Bottoming on cut-down front bump stops results in heavily loading the outside front in corners. Lost a ton of front bump travel due to camber plates and -1.25" ride height with springs...

I think I know why :laughabove:

PS, I am bringing the Motive Bleeder cap from my Porsche up to NHMS if you didn't get one already.

Thanks man, I got it yestiddy but haven't trial-fitted it yet...

I too fail to achieve 'slow in, fast out' far too often.

Correct! No power and understeer (no front camber adjustment), the fronts get lots of abuse and the rears get very little.



I found it kind of funny that the service techs didn't recognize why.. I mean my RE-71rs look like I put a blow torch to them they are so melted... Can't imagine I am the only 86 that comes in this way.

For what those tires cost, wouldn't a set of camber bolts be a no-brainer? Or are class regulations keeping you from modifying your suspension? :thanks:

I have a set of camber bolts in the glove box.... Doesn't seem to help :)

Cool! :thanks: I have tried camber bolts in the bottom hole, top hole, and both holes on the strut; I haven't tried them in the glove box.

How much camber do you get from them in that location? :popcorn:

The upside to swapping between DD and autox tires - every event gets a rotation.

I'm still wearing the fronts faster with -4° but that's a nut behind the wheel problem... well at least my setup changes haven't moved the needle a bunch yet.

Not to mention 55/45 weight distribution! Doesn't seem that terrible until you realize that the fronts carry ~20% more weight than the rears do :mad0259: There should be a cab-rearward 2-seat version of this car, with rear wheels shoved about 10"-12" forward for 50/50 distribution!

I only get about -0.0000000000000000000000001 due to a slightly lower ride height from the added weight.


Have noticed a strange rattling noise coming from the glove box though ever since I put them in. Super easy install though.
