has anyone put bigger tires on their stock wheels? I have a 95 with the blade style stock wheels, Its about time to replace the tires so it would be nice to go up in side wall height a little to fill the fender a bit as well as wider because wider just looks better. Any help ? Thanks

You can go taller on the sidewalls thats easy say you have a tire that is 275/40/17. The number 40 is 40% of the width. So if you can find a 275/50/17 it will be a taller tire. Now your speedometer will be off you will be going faster than what it reads. Also it will show you as traveling less miles than you have traveled. I think you will need to have your speedometer recalibrated or your computer will be off. It will be adjusting for one speed when you will be going another. :eek: As far as putting a wider tire on your rims that could be a bad thing. It will cause the tread to wear uneven and can in some cases cause the sidewalls to fall. If I were you I would keep the tire on the wheel that it was designed for. If you want a taller tire and a wider tire then it would be better if you also bought the right size wheel to go with it. If you go with a bigger diameter have the speedo calibrated and you will be much better off.:cool:
