I just got a set of 18' wheels for my Accord, with 215/35R-18 Kumho Ecsta Supra 712's. The problem i'm having is that between 45 and 75 miles per hour, I get a pretty significant shake in the steering wheel, back and forth. It seems to be worst on asphalt, better on concrete, and goes away as I pass 75 mph. It also seems to be improved slightly when I'm on the throttle.

I believe it's an issue with the balancing, but I wonder why it goes away at higher speeds?

I also checked the tires when i filled up at a gas station, and despite tracking perfectly straight on the freeway, the outboard edges of the front tires feel noticibly hotter than the middle and inner sections. Inflation? Camber? Toe settings? should I take it to a different shop and have them chack the balancing and alignment?

Thanks for any advice

I have an Accord with the same problem and was told that my rims were bent. Problem is that after replacing the rims and tires, it still vibrates. I've had the new rims/tires re-balanced and rotated and the car aligned twice, still vibrates. Maybe worn suspension parts are the cause?

Take a look here. It is really too hard for me to say for certain over the phone.

Are you using correctly-sized hubcentric rings on the new wheels?
