What's better...19" or 20" wheels?

Or how bout 19" front and 20" rear. See my pics. If I had to have one wheel set, I would stick w 19s.

If the 430 is like my 360 I would stick to 19 inch. Sometimes the front wheels will grab the fender over wheel and pull it outwards. There was just a post about this problem about 2 weeks ago.

 

What width tires are running up front.

 

Bob- To run 20" wheels with somewhere near stock tire diameter, you need lower aspect ratio tires (say 30s vs 35s). This means there is less sidewall rubber between the wheel and the ground, so ride will be slightly compromised and the chances of bending a wheel on a pothole will be increased. Because of the taller rear tires (~1.65" larger in diameter), the rears can handle a lower aspect ratio tire better than the fronts. So 19" fronts with OEM F430 sizes and 20" rears with lower aspect ratio tires are a pretty good compromise. Plus you will not be subject to increased tramlining and possible fender interference with the wider, lower aspect ratio front tires.

Remember, OEM fit for the 599 was 19" F and 20" R, and for the 612 18" F and 19" R, so there is a precedent for larger rear wheel diameters.

 

Not really true and you can calculate the height of the sidewall easily by just multiplying the tire size by the aspect ratio. On OEM front wheels 225 x 0.35 gives 78.75 mm side walls. A 295/30 20 has ~ the same diameter as the 285/35 19s (26.97" vs 26.85") and 0.30 x 295 gives 88.5 mm side wall height in the rear.

So much misinformation out there. (probably some coming from me, but not this time)

 

Michael- 295/35 20s are 28.13" in diameter, which is 1.28" bigger than OEM, 4.77% larger, and getting into the area that causes ABS/ASR/CST problems. Did you mean 295/30 20s? The diameter increase is actually 10 mm x 0.35 x 2 (7 mm) x 2 plus 1" (25.4 mm) or 32.4 mm. A lot bigger in diameter.

Fronts are close to the same diameter.

 

The pics up top were a fun project for me. A forum member bought my 18" modulars for this set plus cash. They were in very bad shape and I had them refinished for fun. My favorite set of wheels are my 19" F430 OEMs finished in Scud grey.

Before you spend the money..I suggest you consider spacers and a slight lowering of suspension.

 

Those look great, some 360 owner will be very happy to buy them.

How about some OEM Scud or 16M wheels and you have no worries with them? The 458 style wheels used on the 16M are very attractive, as are the Scuderia wheels.

 

Hi Running 19" Fronts and 20" Rears. They work well on the 360 but not sure on the 430. Kind regards Gary.

Taz, hate to correct you but it's 16M style wheels that are used on 458's.

 

I agree the 16M wheels would look great, and if I am remembering correctly, they are forged (vs the stock wheels being cast). They would be lighter and stronger. And look awesome. And are also factory- I tend to like the factory look- but thats just a personal preference thing.

 

I have 20" HRE P47s.

I run 245/30/20 front | 325/25/20 rear tires.

No rubbing.

Car is lowered forgot by how much, but there isn't any finger gap all around so safe to say it's pretty darn low.

Thinking of downsizing to 19s just for sheer performance & tire options.

Ride compliance is indistinguishable between 19s and 20s imho.

 

Russell- Details, details. You are correct. If I said 16M style wheels, though, most people think Scud style wheels instead of the 5 spokers.

 

Consider the standard Scud wheels, the extended spokes make them look bigger
than 19", and the fronts are 8" wide so can run a 235 thus reducing under steer.
You can pick up a set for around $3200/3600 if you look around.

You can get close to that for your current wheels, so a very cost effective change.
Being Ferrari oem wheels makes for a easy resale if you want to change in the
future or if you sell the car.

With 20" on the front the standard front brakes look puny....

20s visually "fill up" the arches perfectly imo, even though the rolling diameter may be the same as 19s. Gives the car a more aggressive stance.

FYI 20" forged HREs are lighter than the oem Scuderia 19s.
