Yokohama Advan DB is a very good tyre, very soft and less noisy. Similarly, Continental CC5 is also a very good tyre.
I have 2005 and have placed Pirelli P4; they are really good. 28k but very little treadwear.
All these Yoko/cc5/P4 are much softer and less noisy than SP 490; SP490 is a very old design tyre.
185-70-14 is bit oversize; 185-65-14 is ok w.r.t speed callibration but will make your car half inch down
For 15 inch, ideal size is 195-60-15 w.r.t speed callibration. But for road clearance, 195-65-15 is ok making car half inch higher; however, tyres (15 inch with 65 profile) will get close to your body.
BTW 195-65-15 tyre is used in Premio.
MAKE SURE that the tyres you buy are not of a very old stock. 6 months or 1 year old tyre is ok.
