I've been happy with the Costco version of your tires - Michelin Energy
MXV4's. I keep them inflated about 4 ~ 5 PSI above the pressure indicated
on the door label. I get a slightly harsher ride and longer tread life and
probably get slightly better fuel economy.
I'd not base the life of the next set of Michelins on the last set. Auto
makers are able to buy tires with less tread on them to save a few bucks per
tire. Over the millions of tires they burn through while building cars, this
few bucks adds up to a pile of money.
If you were happy with the performance and the various other benchmarks for
measuring quality -- besides life -- then buy another set of Michelins. The
tires you buy will undoubtedly last longer than the tires that Toyota
Having said that, visit www.tirerack.com and you can read what others have
to say about pretty much any tire that has ever been built.
The tires installed on new vehicles do not have less tread on them than
replacement tires. Typical tread depth on the original tires is somewhere
If a tire had less tread, then the overall diameter would be less, resulting
in poorer fuel economy, or the rest of the tire would have to have a larger
diameter to get the same overall diameter, which would weigh and cost more.
Original tires tend to have a shorter tread life because the compounds are
biased towards better traction without resorting to more expensive compounds
that offer the same traction with a longer tread life. The bias towards
better traction results in better reviews from automotive columnists, who
usually have a bias towards performance rather than long tread life.
I know the Toyos on my Corolla 1200's wore out FAST! I also partially
attribute that to the smaller Corollas being able to be knocked out
My 1980 Corolla SR5 (Trueno) hatch came with Bridgestone 406s, IIRC. They
only went 125,000 miles! What a rip off! ;)

Gimme that! "La Stinkadora"
Now you got me thinking. I think my 1501 may have been the last Toyota
model to take 'bias-ply' tires. It was the bottom of the line 79 Corolla.
Remember they were advertising it for $3748? My folks spend an extra $100
or so and got me an AM radio. I seem to remember replacing the 155 S 13's
early on. The only cars that might have taken bias plies after that would
have been the Starlet in the US.
OTOH, Dad didn't like radial tires. He worked at Monkey Wards and they got
a lot of their radials back having shed the tread. It took us a while to
work out a bias replacement for what the TE31 (1977) came with. Turns out
the nearest size was B78-13, but they looked like swamp buggy tires on the
Corolla. Surprised we didn’t have to talk him out of a pair of Firestone
Deluxe Champions in the 6.50 x 13 size. They wore out a bit fast because
the specs for alignment were for radial tires, and bias ply tires needed a
slightly different alignment.
Some years later I managed to talk him into radials on the Corolla again.
The size, if I remember, was 165 SR 13.
(Can you even buy 155 S 13's in anything more expensive than the cheap Poop
Boy specials these days? I can't hardly find 175/65R14's for my AE101.
185's all over the place for the AE102's.)
