Hi everyone,

I would like to update OEM wheels to something with bigger lips.
I found these wheels and per website these fit Acura RL 2006 (not POX model)

http://www.atlantawheels.net/brands.php?act=wg&id=841
Look for Advanti Costola A9 (second in first row) or may be Afoso A8 (first in the row). Click to get large image.
I was planning to go with 18' (I am in NY and the roads here are way from being good )
So please speak up.
1. How is ride on 18'?
2. Could I go with 255/45/18? or should I stick to 245/45/18?

Link to main site is here: http://advantiwheel.com/wheel.cfm?id=28
Per RL spec Hub Bore is 64.1, but wheels are 72.6. Thats means what? Some king of center ring. Right?
3. How safe is riding having center rings on such heavy car as RL? Did you know anyone who has these rings? Share what you know please.

Thanks for all inputs

What do you think about these?
OR these:

 

Whereas 18x8 is a good size, you have no idea what the offset is, or what the so called "x" factor is behind the spokes to the mounting surface. You need to speak to the manufacturer and the retailer and get a fitment guarantee so that you may return the wheels after a test fit should the front calipers rub...The large front brake calipers on the the RL have frustrated more than a few.

245/45-18 is the proper size, and 255/45-18 is a little larger diameter, but would probably work. Not sure of anyone that has used that size on this board. Usually, though not always, you go to an alternate size because the exact plus size is not available. Case in point is when you go to 19" wheels. Two or three years ago, 245/40-19 was not a commonly available size, and there was more choice in 255/40-19. So people accepted the larger diameter in order to get the 19" wheels.

You definitely need centering rings.

Make sure the wheels are TPMS compatible, and those units are fitted to the wheels before the tires are.

 

Chas2:
The offset on these wheels is 42. Somewhere on this forum I saw info that offset from 35-55 will fit, so I assumed that 42 will be just good. What did I miss?
"x" factor. Hmm... If that in not big a deal could you briefly tell what "x" factor is? and how it may effect selection of the wheels for our RLs?

Per wiki:
X-factor
Caliper Clearance (X-factor): The amount of clearance built into the wheel to allow for the vehicle’s brake rotor and caliper assembly.
But there is no x-factor data/info for any wheels. (not only Advanti per say). Wheels specs look like this data below:

Advanti Part # Size Offset PCD 1 Bore Cap Color 1 Load
A98851235SF 18x8.0 FR 35mm 5x112 66.6 CAP2MC FSFP 1,700
A98851245SF 18x8.0 FR 45mm 5x112 66.6 CAP2MC FSFP 1,700



Thanks

 

those wheels are horrendous. but I'd go for the second one, if I had to pick one.

 

horrendous... Odd. Could you please point me to better wheels for RLs (say per your taste).

 

The so called "x" factor is the unmeasured clearance behind the spokes from the mounting surface. I have colored this "x" factor area in yellow in the illustration below. You can have plenty of offset, and still not have enough room behind the spokes. Factory spec wheels have a high +55mm offset. Your 42 will move the outer edge of the wheel 13 mm toward the fenderwell and the inner edge 13 mm away from the suspension, but may still not have enough clearance behind the spokes.

This is why you need a fitment guarantee, in my opinion.

 

Got it. I will be calling the Advanti main office to find out.

Any words on the center rings? (please refer to original post and 3rd question in it). Thanks

 

You need centering rings. this car is designed with a hubcentric fit. Talk to your manufacturer or retailer to verify the size needed. The web site would seem to say the wheels are 72.6 mm, and you will need to go to 64.1 mm. They should be able to help you. If not, I would call other wheel retailers for a start...Tire Rack, Discount Tire, etc, and see if you can get a lead on them. Let us all know what you find.
