I have purchased several sets of aftermarket wheels for various cars. Billet Specialities for my '65 Riviera GS, Maas for my '07 Ridgeline, Centerline for my '99 GMC PU, Weld for my 2002 Denali, to name a few. I have ordered on line and ran into two problems. 1. I had a rim split (defect) and it took 3 months to get it resolved from a Calif. Co. 2. Never buy a set until you actually see them. They look different in person than in pictures.
Since my online experience, I have purchased through my local favorite tire dealer. I have found they can get almost any brand you want, even though they don't advertise it. They can tell you what tire/wheel combinations will fit so your speedo is the same. I am talking about low profile tires. I can also offer you a free web site where you can get on and play with the numbers yourself. I have developed over time a good relationship with the tire dealer and he actually enjoys helping me find the right package. He installs after I purchase through him and then I get free rotation and balance, etc. I also have him doing the negotiating with the wheel mfg if I break a rim, which I hope never happens again.
Make sense? I shop on the internet at some of the wheel websights and find wheels I am interested in. Then I talk to my tire dealer and go from there.
Tires: You will want to express 1. Low profile, 2. long wearing, 3. quiet riding, 20" in size probably due to the fact 20" are much more readily available and the tires will cost a lot less than 19" tires. My dealer has already told me that.
Our Enclave has the 19" chrome and they look just fine, but my other cars have always received the face lift. The Ridgleine has a painted center aluminum wheel with an outter stainless ring. Really looks sharp, but each vehicle and personality has it's requirements. I put those rims and Continental tires with a quiet ride and 460 wear life for about $1500. That is a long way from $3800.
My Custom Riviera received forged Billiet Specialities polished wheels (not chrome) and I gave $2800 for the wheels alone. See the difference? And they are only 17". I spent 2 hrs last night polishing them for a car show this Saturday. Pretty, oh yes, but practical for an every day driver? No way!. Talk to your tire dealer and trust him. Good luck to you, Sir.
