So, aside from ghetto-looking chrome "dubs", has anyone seen 20s on a bonneville. I'm looking at some that would seemingly be awesome.

Enjoy the harsh ride and poor handling, not to mention decreased accelleration and poor braking.

As far as accelleration and braking, why would there be a difference, as long as the overall diameter and weight are the same? I could see there being a marginal difference in centripetal force just from more wheel mass and less tire mass toward the outside of the radius, but overall, I can't see how it'd be a huge difference.

As far as ride quality is concerned, I can't argue with that one. Sidewall is sidewall.

I'm just tossing around the idea, though, mostly.


Having said all that, willwren'* got a nice-lookin' car there.


The handling'* the part that'* got me the most, though. The only two things I can foresee being negatively effected are torque steer and maybe it would react more to road imperfections. But, with the weightiness of the steering, I can't imagine that it'd be oppressively bad.

My chief concern, truth be told, is the girlfriend driving the thing on 20s...

The rotating mass is a big difference for accelleration and braking. Not insignificant at all.

Cornering will be much worse. The car will not stick the corners as well with no sidewall to flex. It will be much more difficult to keep the 'patch' in contact with the road.
As you enter a corner, the car will try to make that contact patch on each wheel 'skid'. The more the sidewall can flex, the less likely you'll slip in a turn. This will result in an overly 'tight' condition.

Uneven roads are the least of your concerns. And that'* not willwren'* car pictured. Willwren'* cars are in the post BELOW that.

for cornering purpuses, anything larger than an 18" on a bonneville will start to have a negative affect. a lighter weight 17 or 18 inch will give you the best performance.

10-4. Catchin' what everyone'* saying.

Just spitballin'

Totally agree that a difference in mass would have a negative effect.

But, if the wheel/tire combo weighed within a pound or two of stock, I figure it'd be good to go.

the lighter the rims means the more expensive they are, light weight rims get VERY pricey
