Replaced original Dunlops on my 08 Accord LX(steel wheels). I am having a slight ride quality issue with the new ones, and have had the balance checked(not road force) 2x since I got them. I read an old post where it mentioned an occasional need to road force balance on these cars. I am having symptoms of the tires not really being in balance. Is there a reason for the need for a road force balance?

 

If the tires are new, on old wheels, I'd just as soon suggest wheels might be bent? With all the protective safety shrouds to cover up the spinning wheel (on the balance-machine) the worker might not notice a bent wheel unless you ask him to actually look for it.

OTOH, you can check yourself by jacking up each corner of the car & spinning the wheel.

Some brake problems can mimic a wheel-balance problem. Also might be the inboard CV joints on the front axle, especially if it only happens under acceleration.

 

Maybe I'm just not used to the new tread...I don't know. It's only on rough road surfaces at 60mph +. I'll let them break in and re-balance in a few thousand miles i guess. It's just weird, like the tires dont want to balance.

 

Update. Using the 10% less than maximum pressure listed on the tire(39-40lbs) theory has greatly improved, if not eliminated the issue. I guess I'm outdated, as in the past I would have considered that to be too much.

 

A better starting point would be the pressure on the car's sticker, which is probably 32psi.

 

I know right, 30psi, even pulled 8 or so pounds out after they installed them. 30 psi worked ok for the Dunlops.
