I would not advise doing that. At the very least buy them in pairs, regardless of the tire you buy. I know they are expensive, but you will notice a huge improvement. Maybe buy 2 of the Michelins now & two more in the near future. Just don't have 3 of the same & 1 different.....your asking for trouble that way.
yea even if i wanted to get the 2 michellins on the same side (on the front) i wouldnt be able to cuz they dont allow it. they told me it's either all 4 or nothing. so i can try getting 2 bridgestone RE950s for the front... dammit i dont know what to do.
