    I had the first race of the year yesterday. I put 195/60/14's on the front and 15's on the back. Since it's a small track i put 14's on the fron to get more RPS's. All of last year i only ran 15's with no problem, but when i put the 14's on i drove it around and everything seemed normal and we didnt get hot laps so my first time on the track in the heat race and i started third and after the first corner i was last. The car was washin up really bad and i had no clue why. Im pretty sure its not the setup because the two times i went there last year i was in the top five both times but i had my 15's on in the front. When i got back to the pits i took both tires off and was gonna put the 205/70/15's on and when i took the 14's off i noticed the tire was rubbin on the shock so when i go into the corner as the shocks went down in locked the tire up against it which washed me up and i couldnt turn. I dont see how a 15 would work and a 14 won't. Has anyone ever had this happen or have any suggestions of what i can do? Thanks in advance

    Yup, sounds like too tall of a sidewall. I bet they are 70 or up. It is a ration of the tire width. At 70, the sidewall is 70% the width of the treads.

    When you say rubbing on the 'Shocks", do you mean 'Struts'?
    Also, rubbing on the tread or the sidewall?

    We used to run Sumitomo's but when we switched to Hoozier's, my right front rubbed the strut on the tire's sidewall. Had to back off on the camber to maintain clearance. ( Blew out a brand new tire in 25 laps.)

    The circumference of the 205/70/15 is 82.6" and the circumference of the 195/60/14 is 72.9" or 11.7% smaller, so my guess is it's the width that's causing the rubbing. Here's a link to a tire size calculator that might be helpful in finding something that will give you more rpm without rubbing.

    I think all you guys don't realise that the 195/60R14 will be smaller in every dimension compared to the 205/70R15 that he had on it. 195 mm wide, 60 percent of 195 in height. 205mm wide amd 70 percent of 205 in height. 14" rim makes it 1" shorter already, plus it's a 195/60 to a 205/70. HUGE difference in height. The 195/60 will be both shorter and narrower than the 205/70. For this reason, I'm betting your car has bent struts. This will cause the tires to rub. My grandpa's lx had the same issue, and when he put new struts on, he could run big tires again.

    But what I can't figure out is:
    How the hell did you get 205/70R15 to fit on your car in the first place??? I can't even fit a 195/70R14 to fit on the front my car without it hitting the strut!!!

    Well I made a mistake i had 205/55/15 and the 14's were 195/70/14's so thats why it didnt make sense to you racerboy lol they were a taller tire and that would be why there rubbing. So that means the biggest tire i could have is 205/55/15? is there a way i can get a bigger tire on there without hitting? Also I dont think my strut is adjusted witht he camber so that could be a problem, but i think i figured it out now and thanks for all the help!

    camron the biggest 15 u can get on there is a 205/60/r15 u may have to massage the strut plate just a tad but, or u can go with a 195/60/r15 thats what i used to run on that car at my track and it was perfact

    i have a 95 Escort GT. dont know if this will help or not, but heres what i do. i run 2 tracks, and use 2 different tire sizes. no modifications are done to my car. i have new kyb struts, and the alignment is tweeked, but thats it.
    the first is a longer 4/10ths mile track. i run 195/75r14. beleive it or not, the are a tiny bit bigger than the 15's i use to run. i use to run 195/65r15's and would top out 3/4ths down the straight. with the 195/75r14's, i dont even hit that annoying rev limitter.
    the second track is a 3/8ths mile track. i run 175/65r14's and a perfect race day i can hit the limmiter just at the enterance of turn 3.

    The KYB GR-2 struts are a factory replacement. I am running them with 1.8" lowering springs. New struts will always be an improvement. If lowering the car, many opt for the S/R struts from the 3rd gens. You will just need the mounts from a 3rd gen to use them. My suspension is tight from the lowering and the Suspension Techniques sway bar kit. I have an additional 3/4" bar in front and a 7/8" bar in back. This thing handles and is very responsive. The KYB's have taken abuse for the last 7 years and show no signs of leaking.
