Only 2 new tires

So the other day I hit an aluminum step ladder on the highway going 80. It put a small gash on the inner sidewall of both front tires and last night I found one of them flat. the tires it had on were 205/55/16 Bridgestone TA Traction. Which I must admit is a pretty decent tire in all conditions. I went to Goodyear (cause thats where I have a credit account) and I picked out some Goodyear Assurance Triple treads. I have put those tires on 2 cars of mine before and figured I'd try them on my REX cause I don't visit the racetrack or street race. So here's the question. Will this harm my tranny? The Bridgestones only have 10K on them and the tread depth of the new tires looks and feels deeper. Will my car give me warning of a problem by an idiot light coming on or is that just on an auto 4 speed tranny?

For AWD systems, all 4 of the tires need to be the same tread, brand, etc. The front tires will wear differently then the back tires. Just replace with all 4 of the tires with new ones. It will mess up your differentials too

Yes, this will #### up your car.

Unless you can get the 2 new tires (same size, brand & model) shaved to equal radius/size of the other 2 existing tires don't replace only 2 tires. As stated above it will cause damage to your center diff.

I talked to a mechanic at the dealership and she said that it can only have a difference of 1/4 inch in tire size of tires to not F-it up. So tomorrow I'll be searching for a place that has a caliper big enough to measure my tires and if there is a greater than 1/4 hopefully find a place to shave them down so I don't have to drop another $300.

It's not just the diameter. Different tires bend in different ways. Over enough miles, you can brake things.

I went ahead and got all 4 tires Goodyear triple tread, (thanks to your advice) and noticed something huge, something unexpected but hoped would happen. My car handles better now! I've put these tires on a V8 Mercury Cougar and a Grand Prix GTP and got great results but was skeptical about them measured up to TA Traction. I spent a good 15 min in a parking lot turning tight circles and doing evasive maneuvering and those bastards stuck like velcro. I guess these tires are not recommended for for WRX's by the manufacturer cause they carry an H speed rating and the WRX requires a V. I cant say I frequently go over 130 MPH so they will be okay for me. I'm gonna go tear up some windy lake roads now, thanks.

Good move man, trying to replace 2 out of 4 tires is almost always more trouble than it's worth. Hopefully your improved handling helps you forget about the extra money you had to spend. Glad to hear it worked out.
