I have a Gold 2008 "Sweet Release" 5.0 program car with standard height springs; but it came with ground effects package.
I want to fit the largest diameter Wheel/ Tire combination that will not have any interference in the well. I do not need a fat (wide)tire. The original 55 aspect ratio or anything close is OK. Something close to 225 or 235 will give the box a little softer ride and that's OK too. What I also need is a quiet ride tire. Thanks, Lou

I currently have 20"x 8.5" with 35 series tires, but no ground effects! Ride is only slightly rougher than stock!

Quite a bit has to do with the rim width. Each manufacturer has a chart as for which each tire size. Make sure the rubber will fit the rim. The stock steelie is 6.5 inches, with a 45 offset. If you go wider, get a smaller offset.
225 and 235 are mm measurements across the road face of the rubber.
The largest is 3cm wider than the stock 205s, or 1.5cm/side.

if the box is lowered, the shape around the tire top changes (it is closer to the body).

can you elaborate on much rougher the ride is with the 20's?

I am trying to find a particular rim right now and most dealers only have the 20s in stick instead of the 19s that I would prefer. Are the 20s giving you any problems with rubbing or driving at high speeds?

no problems rubbing unless you hit a good size bump in the road, the rougher ride i was refering to is just more road noise( due to more tire on the road), and the suspension feels a little stiffer!

Reordering the above to make better clarity:

Hey BMF,
Did you lower you xb at all?

 

[JOEY G-xB]

Thanks TJ for the fix on my last post...To answer the other question, no lowering done, just got big wheels!

 

[LouZ]

Well I guess no one tried to do what I wanted. I didn't get any answers to my real question.
I wound up using Stern 17" Warp wheels model # is S-14 . went with Kumho 225/55/17 Platinum LX Tires. = Smoother, softer, very much quieter ride. Stick like crazy on 90 deg. turn AND NO RUB AT ALL .. Shifting seems good. I have not locked them up to check the Anti Lock brakes.
Now if I can find out where to get plugs for the hollow lug nuts.... Lou

 

[LouZ]

Well The Job is complete. Final Tire is Kumho, Platinum XL, 225/55/17, on Stern's wheel model ST-4 Warp, in Bronze color. The Wheel color very closely matches the car color. It really looks like it should have been a factory install. ]We use the original tire pressure sensors in the new wheels, and are running the original 35 & 32 psi. respectively.
  This combo gave an excellent smooth, quiet ride, and does not rub under loading, and hard cornering conditions.
I have not yet tried a skid pad of sorts to check the qualities of the anti-lock brakes. I also have not checked the Speedo difference in the GPS. I did check it with the original tire/wheel combo, and found it accurate to + 1 mph.

That's it I give up,
Maybe it's because I'm on dial-up. That's all that is available here except satillate.. But I spent 1 hour setting up and trying to include a 2 pictures. It did not happen I'm done, It ain't gonna happen. Bye
