So the winters is almost gone and I'm gonna put on my 16s soon but till then I'm on factory steel wheels and need new tires for 2 of them, the tires on them are 195/60/14 and I'm getting a good deal at work for 195/75/14, but the guy that was selling had some concers of the tire fitting the car so would the bigger sidewall make a difference? or would it be ok to put on the steel wheels

 

That's a lot taller than the stock tire. Besides odometer accuracy, I'd be worried about rubbing the fenders.

 

If your car's lowered you're gonna tear up your fenderwells and you'll probably pop a tire as well. And like previously mentioned your speedo's gonna be way off as these tires are huge on your car.

 

stick to recommended tire sizes..

 

I'd say you could probably slide with a 195/65/14, but I wouldn't even try a 75. They are going to be really tall and will probably rub. Plus they'll look dumb compared to the other 2 60s on there. Just buy some new ones from tirerack.com, 195/60/14 size tires are pretty inexpensive, especially only 2.

 

See for yourself. I wouldn't do it.

According to that, your speedo will be off by almost 10%, not to mention the potenbtial hazards to you and your car.
