I'm running 215/50R17 BFGoodrich Traction T/A
Very good in the wet stuff, even better in the dry.
Very stiff sidewalls compared to the crap it had when I bought my car.
Rougher ride but I like the sporty feel of them and they have much better wear than the ones i had before (Cooper Lifeliner GLS)

Are you basing those numbers on ACTUAL tire specs (which vary and are not precisely what the sidewall says)?[/b]
Dunlop states that the Direzza DZ101 in the 215/45R17 suze requires 842 revolutions to cover one mile.
Michelin states that the Pilot HX MXM4 215/50R17 in the 93V configuration require 819 revolutions to cover one mile.
The sidewall specs suffer from granularity. A section width must be specified as a number ending in -5, so a 210.1 mm wide tire is a 215, and a 209.9 mm wide tire is a 205. Aspect ratios are also stated as multiples of five, so a tire that has a sidewall height that is 47.4 percent of its section width is a 45, and a tire that has a sidewall height that is 47.6 percent of its sidewall height is a 50.

but based ONLY upon stated (sidewall) tire size comparisons at Miata.net's Tire Calculator, the error is a 'mere' -3.3%, not -9.7%.[/b]
The Miata.net calculator assumes that a 215/45 tire has a section width of exactly 215.000 mm and an aspect ratio exactly 45.000 percent. Neither of those conditions actually obtains in the real world.

Sounds like you're assuming (or can you confirm?) a uhge inaccuracy in the Dunlop/s stated size! Or am I missing something?[/b]
Clickable links:
For the Dunlop Direzza DZ101 215/45R17 (842 revolutions per mile);
for the Michelin Pilot HX MXM4 215/50R17 93V (819 revolutions per mile).
819 divided by 842 equals 0.972624 -- that's a 2.7316 percent difference; 842 divided by 819 equals 1.0280083 -- that's a 2.8083 percent difference. Round either to three percent. Did I write 9.7 percent above? (I did.) Sorry, my bad.

I just put a set of Goodyear GT's on the car. I replaced a set of Perilli's M&S that lasted 24K miles. The Goodyears feel good in the rain and on the diffrent types of road I encounter on my way to work. The tread depth seems more than the Perilli's when they were new, and they are quiet.

Sumitomo HTRZ III 225-40-18. Daily driving and autocrossing, they work very well, a bit more grip than the stock RE050A's but just as noisy. They lose their grip when they get over 170 degrees. Highly recommend if you want a tire with good road manners, but enough grip for those autocross sundays. Oh did I mention how cheap they are? They go for $111 at tirerack!

Just bought Fuzion ZRi(s) for $91 each at tirerack.com. So far the difference is night and day compared to those HORRIBLE stock Michelins. Better braking, no squalling, VERY grippy, less understeer, strong sidewalls (very little "bulge" and no rolling even at a 35psi inflation rate--max pressure is 55psi!). Going to the race track this Saturday to give them a *real* test. WOO HOO!!![/b]
I have heard very good reviews about this tire and plan to get them. How have they held up?

Mazda MX-5.
Bridgestone Potenza RE050A run flats.
205/45R17 84W.
They suck.[/b]
2008 Mazda Miata:
Bridgestone Potenza RE050 (not A) run-flats.
225/50R16 92V.
They suck less.

Ok , after reading countless pages of tire posts I am tired and still undecided on what tires I want. I just bought a set of Michelin Pilot Alpin PA3 snow tires for the stock 17s (review thread coming soon) and want to replace the annoying Toyo Proxes 4s on the RX8 wheels this winter. My requirements are: non-directional, quite road noise, good wet and dry traction,
and prefer a W/Z speed rating. Tire size is 235/40/18. Any recommendations appreciated.

Summer or all-season?

Also, why non-directional?

Wow, I've been gone a long time. But it's finally time to replace my OEM Michelins and have NO idea what to switch to.
I'm thinking maybe the YokohamaAVID W4S

Just ordered a set of Dunlop SP Sport Signatures to replace the orignal Pirelli Zero Neros. I'll repost after I get a thousand or so miles on them...
