I just had my new Fittipaldi's mounted this past weekend and after driving a little bit I like the way the steering wheel responds to the wider tire trac. I had the puny stock 13's on the car and bumped it up to 15's with 205/50 series Bridgestone tires. The ride feels so much more solid. I also notice that the car handles about 5 times better.

 

I believe the DX came stock with 13's and LX stock with 14's. Upgrading to the 15's was a great move!

 

Happy Freakin' Birthday!
With a bigger tire, there will be more rubber that touches the road...that will allow for better handling esp in corners and it will offer a better ride quality.
I notice my car rides 5 times better with a wider tire...the ride feels more stable and the car handled nicely. To me it gave the steering wheel a new feel to it...like I was driving a mid-level car instead of an econo box.

Of course that is all subject to opinion

 

why do u have a link to someone lx protege does ur dx have cruise power windows a tach ? .Bigger tires means more contact better grip better handling but the bigger u go the more power it takes to roll those rims so i wouldnt go over 16 ...Jon
