one tire with different tread depth than others, problem?
Ok so I was on the way to work this morning and driving through a bunch of snow in Denver with my Blizzak Revo 1's. Some plastic piece came flying off a car and across the Highway with perfect timimg to be ran over by my car. I couldn't avoid it and shortly after I had an exploded tire.
So I had to get a replacement Blizzak. Problem was Bridgestone doesn't make the Revo 1's anymore so I had to replace it with a WS-60.
Now comes my question. I have about 7,000 miles on my Revo's and the tread remaining is about 8 to 9/32" and the new WS-60 tread depth is
11/32" So should I worry about my 2 rear tires having different tread depth because the newer tire will be spinning slightly slower than the older tire and maybe mess up the differential? Or is the 2 to 3/32" not enough of a difference to worry about? I guesstimated the difference in circumfrence between the three Revo's and the one WS-60 tire to be around 5 to 6 tenths of an inch (Diameter being .1875 inches shorter on the revo's). Let me know your thoughts.
Hopefully it won't make a difference. I will have to be cautious that having one different tire than the others may give me some interesting traction. But looking at the two types, they are pretty similar.
On a side note, after having to change my tire on the side of the highway in 6 plus inches of snow and slush I came to discover a few things that may be nice for others to know. One thing is that the jack that comes with the WRX in the trunk worked very well. I was doubtful at first but it worked better than some cheaper garage jacks that i have used in the past.
Another thing to note is that the tire iron that comes with the car is short. So if you use it on lugnuts that are tight than you could be in some trouble trying to loosen them. I would recommend getting a longer tire iron to store in the trunk for better leverage in case you have to change a tire.
