Jesse had the 711 as his street tire on the mr2. Sometimes, when we were too lazy to change tires at a local event, we would autox on them. They had a reasonable amount of grip, considering the price, and handled predictably.

Yep. Lots of bad habbits to be unlearned.
I've already decided that once the kit is built, it gets a minimum of 1 full season on street tires.
Jeremy, What you'll find with the mustang is this... it doesn't turn well.
With not so sticky tires, the front end plows just a little bit and the front end slides out in a turn. Common sense says stickier tires will let you not slide so much.
So, you add sticky tires.
The front end grips more. It also plows more. The front springs compress and you get camber gain and end up riding on the outside edge of the tire. Now that you're running on 25% of the tread, the tire slips. The suspension decompresses. The tire lays flat on the pavement and grips again. You start the whole process over. It's completely unpreditcable and a bitch to drive. And you eat tires.
The only way to make it work is to put on insanely stiff springs. I was running 425lb/in coilovers which are roughly equal to 1600lb/in springs in the stock perches. That limits suspension travel during hard cornering and keeps you from eating the outside edge of the tire. It works great on smooth course, but on rough course, you chatter across the bumps.

About the 711s, I like them. I've used 712s before, and agree, they're terrible. The 711s are much cheaper, better in the wet, and handle better, IMO.
They however, are NOT a REAL performance tire, and you won't be happy if that's what you're expecting, but it's a good all around tire.
As for street mileage, I can't really tell you. MR2s EAT tires, fancy alignment or not, they eat rears. I get ~12,000 miles out of a set of rears, and ~20,000 out a set of fronts. On a mustang who doesn't drive super agreesively on the streets, and uses the 245, I think you should, at the VERY LEAST, equal your yokohamas in treadlife.

Why are the Khumo 712's "sucky" tires? I ask because those are the tires that I am currently running on the street and for the occasional autox. I will freely admit to knowing nothing (made obvious by the fact that I drive a Ford Probe), but they seem like OK tires to me. Of course I speak from ZERO experience with any other tires. The reviews I read on Tire Rack didn't say they sucked or I wouldn't have purchased them. Perhaps it is a matter of not being able to go fast enough in my 2.0L I4 non-turbo 2+2 sportscar-wannabe for the tires to be an issue. ; )
I would appreciate any information that anyone is willing to provide. Thanks.
P.S. Sorry if this is thread-jacking.

They just dont have the grip other tires have in wet or dry in my expirenece. They were realyl bad about grabbing crowns and runts in roads and pulling the car 1 way or another. They were a good tire at the time. But now that Yoko Es100s are out and they are the same price, Kumhos dont compare to them.
I honestly consider the 712s more of a touring tire anyway.

Mark, treat yourself to a known good performance tire just once and you'll understand why we say that the 712's suck.
To the average driver, they are good enough, that's why you don't see a lot of complaints in the Tire Rack reviews.
If you're still running 15's, look into the Bridgestone Potenza S-03. I think they're on sale for a decent price right now.

I've been real happy with my Yoko AVS Sports. They have been wearing fairly well (Several DE's and 7,000 miles and still plenty to go) (and Porsche typically eat tires) they are pretty sticky for a street tire - and they make plenty of noise before they let go - which is great for someone learning.
I've heard very good things from those that track on the RA-1 - I've also heard that the Kuhmo MX's are a big improvement to the 712's (which if you have them - better make sure you keep them blown up!)
I'll also Echo Loren on the recommendation that you stick with streets for awhile.

How do the Kumho MXs compare to other 225s...do they 'run wide'?
I have a pair of falken fk451s and a pair of goodyear eagle f1s, same sizes....the falkens pose no problem at all, but the goodyears rub up front. I'm way due for a new set, but I don't want to buy new tires only to find that they won't really fit on my car.
