First of all, the Box was not designed to have the same sized tire at all 4 corners. It's designed to have a stagger, front to back. This is the info I found for stock wheels:

WHEEL SIZE FRONT16 x 6
WHEEL SIZE REAR16 x 7
TIRE SIZE FRONT205/55ZR-16
TIRE SIZE REAR225/50ZR-16

And for the "S" which is a quite common upgrade on the base:

WHEEL SIZE FRONT17 x 7
WHEEL SIZE REAR17 x 8.5
TIRE SIZE FRONT205/50ZR-17
TIRE SIZE REAR255/40ZR-17

Many upgrade the fronts on the Box to a 225/45-17 to give a little bit better balance but it stays on the 7" wide wheel/rim.

I'm sure you're rubbing up front like crazy and the handling has to be a bit out of whack and could be a bit dangerous with this set up. The balance of the chassis is all out. If I were you I would change the fronts to a proper width 19" tire.

Tire rack has this as the 19" option for the 2000:


CONTINENTAL EXTREMECONTACT DW
Max Performance Summer
Front: 225/35ZR19 88Y XL
8.5" wheel

Rear: 265/30ZR19 93Y XL
Sidewall Style: Blackwall
10" wheel


So, even in a 19" wheel size, you stick with the 225 width. The wheel size is also still staggered. You have too wide a tire and probably too wide a wheel up front.
