    Honestly, ET Streets are WWWAAAYYYY more tire than your car needs and you'll have to find the sweet spot for them to come out hard.

    Are they ET streets or the radials? You say radials in your title but gave a bias ply size. If they are streets (bias ply), not radials, that is why your MPH is down. They eat up more HP because of rolling resistance.

    OK, they are bias ply tires. If those are the tires they look like they are not even a matched set, which will hurt performance. What you need to do is figure out what each ones circumfrence (sp) is. Make a strait line on flat pavement and mark each tire wear it touches it when directly on top of the line, roll it 1 revolution and make another line. Measure it for both tires, it should be within a half inch. Or you can get a fabric type of tape measure (from a craft store) and measure around the center of the tire. If they are not close to the same the car will be fighting it's self down the track. If one tire is an inch or so off you can put high air psi in it and let it sit in the sun for a day and it should grow enough. But, just looking at the picture they are several inches off from one another, unless it is a wierd optical illusion. The one on the right just looks f'ed up though.

    Just looks like one is flat and the other isn't, maybe they aren't race-ready in that pic.

    could be the one on the right is flat in the pic, but even if it is it will probably be off from the other one with equal PSI in them. Just trying to give idas as to why his car went slower. Besides the fact that a bias ply will always MPH less than a radial, if they are not matched the car will want to go twards the side that has the smaller tire and then you have to steer to keep strait. Every little thing makes a difference.

    I'm curious what he had for front tires, I've always been told that you never ever mix bias and radial tires on the track, my uncle swears by that statement. But he runs his Ranger in the low 8's, almost 7's, can't imagine that his rules would be as crucial to us veesixx guys.

    Another thing I guess to look at is the age of the tire, the rubber goes hard on them after a few years.

    I ran bias ply rears with street radials up front for the good part of a year. Felt no ill effects in a car going 14.50s.

    Then my thought was right, not something that most of us need to worry about. Good to know.

    that picture was taken at the guys house who I bought them off of...could be just uneven surface, but I'll double check them

    I was running my street radials (hankook ventus HR II 245/50R16) up front....

    tires arent more then a year or so old...they're pretty soft still...
