Like others have said above, the Forte is marketed to sell in the economy class so it competes with cars like the Civic and Mazda3. If you read the forums of those other cars, you'll find the same complaints about road noise. As a subjective comparison, I have driven in Civic's and Corolla's and the road noise in those cars over rough roads are pretty horrible. I used to owned a Corolla before the Forte and there is one stretch of road on my commute to work that was quite bad before they recently repaved it. With the Forte, I immediately noticed a marked decrease in road noise on the same street. The Corolla rode on 15 inch tires as well, compared to the 16s on my Forte. Less road noise than the Civic and Corolla? I would say yes but compared to my Honda Accord, I would say it's no contest. Never really had the chance to test the Mazda3 over rough roads but when I was taking it for a test drive, I can tell you that the OEM tires on it were extremely lousy and noisy... Goodyears I think?
