If the wider tires fit with no interference to steering or body parts, there's no harm in running them. I'm running 205/70/R14's in the front. I like a slightly wider tire in the rear, and I still get good handling with this setup. Here's what it looked like when I bought the 14" rims, and then after I painted them. The front end was a bit low in these photos, I had to crank it up about one turn on the t-bars to get more suspension travel.
