Another RX-8 tires thread...

[Hank3]

I'm purchasing a set of RX-8 wheels next week. A few questions:

1. Will the TPMS from the RX-8 wheels work fine with my Speed3 or should I purchase the rims without them for a cheaper price and just use my TPMS?
2. I was quoted $475 OTD to have tires mounted/balanced on the rims. They're 225/40/18 Yokohama SDrives. Do I need to be looking at the stock size of the RX-8 rims (225/45/18) or should I go with 235/40/18?

The price probably will be higher than $475 if I go with a different size since my local Discount Tire is giving me a deal on the 225/40/18 SDrives since the peron who ordered it doesn't want them any more. They want o get rid of them - supposedly.

I just bought a set of rx8 rims as well that came off a 04 rx8 and it came with tpms but no tires... And I have the same question... Will the tpms that came off 04 rx8 works with 08 ms3?

If you gonna spend that much, I would go with 235/40/18 because this is the closest to stock diam. And no rubbing issues.

The TPMS should work just fine, provided that the sensors are still functioning properly.

The ones that came on my RX8 wheels work splendidly.

I have 235/40R18 tires, and wouldn't personally use 225/40R18 because of the minscule sidewall. The 235/40R18 size already cuts it closer than I'd prefer.

The 224/45R18s of course give you more sidewall, but you run a higher chance of rubbing because of the taller overall diameter...

 

[Hank3]

Have people run into any rubbing issues with 235/40/18s?

 

[DaleNixon]

235/40/18 seem perfect to me.

The TPMS should work no problem. Mine never even tripped the light. And they were in storage for a few months before I put them on.

Just get ready to start considering springs or coilovers:

 

[Hank3]

Well that's good to know that the TPMS sensors work fine.

 

[Hank3]

What kind of Kumhos are those, Dale?

 

[DaleNixon]

Ecsta SPT

 

[Hank3]

How you like them thus far? They look nice. Were they pricey?

 

[DaleNixon]

Freaking great tire. They grip well wet and dry and work great in non-freezing temps.

I got them from treadepot.com for I believe around $450 shipped. They had a $50 off coupon code out on the net.

 

[Hank3]

Thanks for the info!

Dale,
Do the MS3 lug nuts work with the RX-8 wheels?

Yes.

Thanks!

Yeah i have Kumho SPTs on the front stock wheels and they are awesome!! The gap with 235/40 seems big on the picture and i will hate to lower my car just to get rid of the gap but I also hate to put 215/45 on a 8" width wheel. Dilemma....dilemma..

 

[Hank3]

What PSI are you guys running on the RX-8 wheels w/non-stock tires? Are you following the stock 34/32 specs?

 

[Kain]

I run 35-38 for DD.

 

[DaleNixon]

35 all around.

You will feel the extra sidewall stiffness and notice the extra inch of rubber on the road. It's nice!

 

[Hank3]

Why less in the front Kain? I figured I would still need to run more in the front due to FWD.

No, 35-38 is not F/R, it's just a range that I keep all the tires inflated at, anywhere between 35-38. I typically keep them all at the same PSI, unless I'm autocrossing.
