Default Do concave rims have to be wide?

Hi all

I really like the concave rim trend, looks wise; however I'm not really convinced that the extreme width of those concave rims do any good for performance. I do understand why wide rims become concave (extra width is added to both sides of the horizontal axis of rotation), but I don't see why concave rims have to be wide: couldn't less wide rims have the extra offset that creates the concaveness, without the extra width?

I hope I'm making myself understandable...

It is possible, but nobody does it because of the negative effect it would have on wheel bearings and steering geometry. The only time an offset such as you describe is used is on dual rear wheel applications, and only on the rear axle. The inner rear wheel negates the geometric problems associated with such a mounting.


You can get somewhat close to that look with RWD offset, which is really 0 offset. But to do that you'll need to buy an older car or truck, this offset has been phased out over the past 15 or so years.

1985 Ford F150 | 4x2 | 300ci OHV inline six | 4-speed OD manual | 310K | No power brakes | Running 100% - It hasn't driven this good in 15 years!

1984 Ford F150 | 4x2 | 300ci six | granny four | 3.55 rear end | 210K | Brakes shot. Rear drums are doing most of the work. Not fit to drive due to that.
1997 Ford Explorer XLT | 4.0L Vulcan V6 | 5-speed automatic | shift-on-the-fly 4WD | 210,000 miles | Running 95% - Needs brakes on all four corners + bald tires
1989 Ford F150 | 300cid six...again | 5-speed | 4x4 | 160K | Needs brakes done as well. Oi!

Thanks for that answer; I can now go to sleep with one less disturbing thought
