Rx-8 rims on CX-9?

[not_too_shabby]

I'm looking for some OEM wheels to put snow tires on. I have seen quite a few 18" RX-8 wheels for sale. From what I can gather they are the same offset and are 18x8. I saw somebody on edmunds say they were running RX-8 rims for winter wheels on their CX-9. Is their anything to be concerned about with running these wheels on a CX-9? Are the TPMS the same?

I would be concerned with weight. Are you sure the lightweight RX-8 wheels can handle the 4300 lbs weight of a CX-9?

[CX9 SportOwner]

I wouldn't. The RX8 has a pretty lightweight, open wheel.

you shouldn't have any problems with the RX8 wheels.. Personally I am looking to upgrade my stock 20s to some Volks in 20s as well with a wider 275 series tires on all 4 corners.

I'm pretty sure they are roughly the same size as the Mazda 6 wheels, and the 6 wheels don't fit. The brake disc is too large.

[CX9 SportOwner]

The issue isn't just size, but weight. In a CX9 you can have 1600 extra pounds just in passengers. Plus the added weight of the car.

I am concerned about the weight increase, but I have never seen a load rating on a rim, only tires....

[CX9 SportOwner]

Maybe you can ask Mazda. Again, car and passenger weight is almost 3000 pounds more. That's significant.

Here's a good article on wheels and load rating.. Should be marked on the back on the RX-8 Rims...

Well it's a mute point now. I found a set of take-off 18" CX-9 wheels, tires and tpms on ebay and I just won the auction. I'm stoked. I'll throw these on when I get them, rack up some miles on the 18" tires, then take the duelers off next winter and put on some real snow tires. Then I'l have 20's for the summer and 18's w/ snow tires for winter!

nice what did you pay for the 18s?

$445 including shipping which is a heck of a deal considering they are almost brand new take-offs with TPMS. I guess we'll see how good a deal it is if/when I get them. The seller looks reputable though. It was a no reserve auction.

Most of the people on ebay are trying to get $1000 plus for wheels and tires but aren't getting any takers. There are set of 18" CX-7 wheels, no tires, no tpms, up there last time I check for $499.

good price considering a single new wheel from Mazda without the TPM is that much.

I'm hoping to sell mine when I get new wheels. Thanks for the data

Let me know when you do and I'll buy them off you, for a reasonable price. You live in the Portland area right?

Arizona

Mine won't have TPMs or rubber, unless you really wanted the tires. Shipping is cheaper without.

[vikefan7]

Oh, I must have confused you with someone else on here. I don't care about the TPMs or the rubber. I just want the rims so I can go buy some good tires that I can put chains on.

I'm the guy that lives in Portland, ;)

[vikefan7]

Cool. I couldn't remember.

Ok, got the 18" CX-9 wheels delivered yesterday. They look good. I can't believe the deal I got. Watch ebay for some oem wheels, and you might get lucky like I did. What size socket do I need for the lug bolts? I have been driving european cars for the last 8 years and my 17mm socket won't help me much with the cx-9.

[benben01]

It's probably 21 mm

[ajmjr27]

Wanted.....CX9 Touring 20" rims. Some carwash moron sprayed something on my rims and now they're stained ! Let me know guys

[not_too_shabby]

It's probably 21 mm

You were right BTW
