Yes. The GT calipers are bigger size so they don't fit anything less than 17" wheels. I just upgraded from 15 to 17 and to me it rides exactly the same IMO. Maybe even softer because the 17's I bought are only nylon side belt (no stiff steel). Honestly, I don't know how you think the 17's are too stiff unless you have them over-inflated. If they're anything over 34 PSI, I'd try lowering the air pressure first. Then, if that doesn't work, you can look at a slightly larger tire. I'm running 215/50/17 which are .25" larger diameter, but my speedo is still slightly under the actual speed I'm going. Might also be able to fit 205/55/17 (.5" larger diameter) under there with the right brand tire. I wouldn't go bigger than either of those two sizes though.

Also, if they're the stock tires that are breaking belts .... the stock Goodyears that Chrysler put on all the Cruisers (regardless of size) suck and are prone to belt breakage regardless.
