Default Tire placement question.

I just got a set of STi BBS wheels for my car. On the tires I bought, two of them have better tread then the other two. Should the ones with the deeper tread go in the front or back. I've got a 2000 2.5RS lowered on Prodrive springs, -1.0F/-.50R camber, and a '02 WRX rear sway bar.

My friend thinks I should put the better tires on the rear because of the combonation of the WRX rear sway and the stock rear limited slip differential my car might be a little bit more rear biased.

I think they should go on the front because my car is heavier in the front and my car naturally understeers.

What do you think??

How much of a difference is there? If it's more than a couple 32"nds, I wouldn't put them on the car at all. If they are pretty similar, I would put them in the front first. Subaru's are nose heavy and they understeer. That way the tires with more tread will wear a little faster than the tires with less tread to even it out a tiny bit.

+1

If you drive hard you will grind the fronts down first. If you don't drive hard the difference could hurt your center diff.

Running the better tyres on the rear is old school. Better traction in the rear keeps oversteer at bay. Rain could be dicey with the more waren tyres in the rear.

If you live in Spokane the RE-070's will realy Suck in the white stuff. Dont't use them! Ive gotten caught out down in Portland and they are down right dangerouse....

The tread difference is mabye 2-3/32"s. They are dunlop fm901 similar to the re070. Would a difference of tire pressure mabye help the situation. Like putting a few more pounds of air in the tires with the less tread??


By the way, I don't plan on running them in the snow, just wanted to put them on for a few weeks since I just got them. I've got the Blizzaks for the snow.

Yes and no. Different tyre pressures could help, but not a big deal.
