Any ideas what this vibration could be?

Right when you doing 60+mph you get a slight vibration in that car! i though it might have been the wheels. But after upgrading to new alloys its still there. There is no vibration through the steering wheel or anything. Its like the road surface is slightly bumpy (nothing to much). IT just a slight feel through the seat. Any ideas/or anyone had this problem?

Have you ever felt this vibration before? Every car has some amount of vibration. You'll never have a perfectly smooth car.

Did you use the same tires with the new wheels? If so, it might be a tire problem (out of round, out of balance, vibration-frequency mismatch with suspension, etc.). If you used new tires, were they the same kind, and what were they?

Nah not the same tyres as went from Steel wheels to alloys etc.

What frequency is it? Once per wheel revolution, or is it more matched to engine RPM?

Your tracking/toe etc could be slightly out.
I though about tires / wheels, but if that was the case then you would feel some vibration through the steering wheel, but in this case, there is no vibration through the steering wheel....

Another thought - is there any reason a rear hub might be bent (slid into a curb, etc.)? That would cause some wheel runout and a vibration at wheel revolution frequency that would not show up at the steering wheel.

Hmmm might get the car alined just to be on the safe side! Just need to get this sorted and car is 100% its one of those annoying problems. As for rear hub i havent hit the car, but i have only had it for a month.

thad.
I was just trying to get the nature of the vibration defined better. If it were at something other than wheel rpm, it might be a bad motor mount or an exhaust system vibration, etc., resonating with the chassis, and it probably wouldn't be a wheel or tire-related problem.
