Rear Tire wear Question

Reviewed the other posts here about rear tire wear but wanted some
additional insight.

Vehicle is a 2000 Miatia (of course!!) with 54,000 miles. Replaced all
4 tires about 17,000 miles ago. Noticed that both rear tires have
significant wear on the inside edge almost to the point of needing
replacement. Suspect this is just a rear alignment problem but wanted
to know if there may be any other cause that I should correct. Vehicle
is a daily driver and not raced (at least not Auto-X).
Thanks

You might taking corners faster--that would tend to eat the outer edges
and even out the wear pattern. :-)

A good alignment matches wheel angles with driving style. Aggressive
cornering requires aggressive camber settings. Front-to-rear rotation is
a good idea, too; I recommend every 3000 miles for summer performance
tires and every 6000 for all-seasons. Tire pressure should be about 28
psi all around in most cases.

Since you may have no clue what Lanny is talking about: you probably
have too much camber for your driving style. Take it to an alignment
place and tell them you are wearing the inside rear tires too much.
Also ask them to check toe to be as small as possible, while still
being toe *in*. Toe out rear makes the car tricky.

I assume you know about tire rotation, and like me, have other things
to do.

It could also be excessive toe, in either direction. Most likely both.
An appropriate alignment will fix both.

I bought a new 2004 in March and now have 24,000 miles on it. I had to
replace the tires last week as they had no tread left on them ( I did not
check them as often as I should have - just assumed that tires would last
longer than this and only rotated once).

Can someone help me understand if this is something that I can look forward
to forever (this is my first Miata and I love it!!). I have 205/45/16 size
tires. I would prefer to replace them next time with higher profile and
smaller size, any recommendations?? I use the car more as a fun commuter
(about 100 miles per day) but do occasionally enjoy taking 30mph corners at
70mph, and also occasionally exceed 100mph during the commute.

Thanks for your help!

Soft, sticky, performance tires don't last very long. Hard,
long-wearing, all-season tires don't stick very well. Your choice.

I went for the best performance, expecting them to last 15k miles. If
you want your soom-soom, accept that tires are a consumable, not an
investment.
