Default Do all 4 tires have to be identical on an '08

My friend made the mistake of going to WalMart in his brand new 2008 WRX Sedan. He his a monster pot hole while avoiding a large woman backing quickly while on her cell phone. The stock Potenza (205/50/17) suffered side wall damage and has to be replaced. He put the spare on this morning and went to purchase a new tire. There are no exacts to be found, and it will take about 10 days and $250 to get one from Discount Tire.
He's thinking about buying two Falken 329s (same size and similar tread pattern) instead and putting them on the front wheels.
Will this mess up anything? On a front-wheel drive car, I would say, "Go for it," but he wants to be sure it's OK on his first WRX...Any quick help would be appreciated as he is at the counter at Discount Tire while I'm typing.

It could casue problems down the road because of different grip levels, and different wear levels. Also, the same size tires from different manufacturers are often not the same diameter. If you can afford it, get all 4 new tires.

Subaru states that all tires must be within 1/4" circumference, which is 0.040" in radius or 0.080" in diameter. Those are the specs I would observe.
those specs are to prevent damage to the center diff. i would personally buy 4 better tires and sell the remaining 3.

The 1/4" rule stands, and they protect the diffs.

However, they also state you should have all the same tires.

What a shame that the car got rocked fast. It happened to me too. But it wasn't because of a fool on a cell phone, so I feel bad.

If you can get the exact same kind, I wouldn't worry about it too much.
I did that with my tire, and it was fine. I had only a couple thousand miles on the tires.

Subaru.com's tire car care tips:
"All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equipment."

He only has about 100 miles on the brand-new car, so a brand-new tire will be the same as the brand-new one that was damaged.
Discount Tire spun the wheel and told him it seemed OK, but it was a hair off. I'm not sure what they meant. I'll ask for further clarification on that.
He is going to order the same Potenza from Big O. The whole thing will cost about $250 (new tire mounted). It's a shame because I think he could get four RE70s or something if he had time to wait (can't the run spare for more than a couple days).

You can run the spare for quite a while, but all those guidelines are there so that there will be absolutely 0 chance of Subaru getting some lawsuits.

Personally I would have waited... 250 for a single tire?! As for the hair off thing, it's most likely wheel balancing. A big pothole might muck up the mass balancing. Nothing they can't fix.

I would wait... Get a set of super mega awesome tires.

if you think that was fast, my sister bought an 08 obs and got nailed in the front left wheel and the car that hit her slid down the entire driver's side. $8000 worth of damage and 2 months later, she finally has her car back. guess how many miles on the odo...












129!

she's gonna trade it in and have the other lady's insurance pay the difference.

Sold! The guy with the bad tire will take them as long as you'll ship...he'll pay shipping. Please confirm the size 205/50/17 Potenzas from an 08 WRX? I'll PM you.

Default Similar problem

I nailed a pothole - bent a rim and damaged the sidewall of the stock RE92. Dealership service dept said tread wear was low enough that I only need to replace the one tire. I replaced the rim and tire and picked up the car but am now worried the mechanic may not have been correct. Tread depth is 8/32 (.25 inches) on the previous tires after 21,500 miles. Bridgestone site states tread depth of 10 (I assume mm) stock, which would be .39 inches. Was the tech wrong? I don't want to ruin my drivetrain.

That's good, because it's time and there's a reason to change another set of tires, the stock tires are not good and very expensive to replace. I replaced mine after 5000 miles, and have Goodyear F1 AS. I'm regret that why I didn't change since day 1. I never had different tires on the same car, you should know it sounds dangerous, unless your friend will not drive more than 50 MPH.
