It is annoying that these updates get installed with no owner information provided... changing this sort of stuff can be a safety issue. "Release notes" or manual addendums should be provided to owners particularly when the changes are significant.

It is not the tread pattern that makes the diff. It is the "slip angle" that the dsc senses as something wrong. Using the same tire in a different size will be ok to a point as wildcard prooves. Using a different brand of tire will toss a curve (pun intended) to the car. It will also do it to the driver. Maybe what you feel is not the dsc but the tire diff yourself. You will feel it like one end has low pressure.
In fact the more I think about it this is probably what is happening. You are more sensitive then the computer. Staggering the tire size is a long used trick with rear drive cars. I think with added power this is going to be nessasary anyhow.
The only way to know for sure is to take a bunch of tires and wheels ans two or three cars to the track.

Driving with staggered tires of different tread pattern feels like crap and extremely unsafe.
The car felt unbalanced and felt like it rolled around alot. Does that have anything to do with the different sidewall stiffness etc on the tires?

Greetings All,
Could I ask those with Nankangs where you got them from - was it a chain like Bob Jane, Jax, or one of the other big mobs ?
I'm on the NSW Central Coast and we have most or all of the major players here but it could take a while on the phone to locate tyres so any help with seller would be appreciated.
I looked on the Nankang web site but couldn't find a list of stockists anywhere.
I was told the other day by a mechanic issuing me a blue slip for the RX-8 (long story - will share soon !) that our front tyres are beginning to scrub on the inside and are only just legal (it's at 29,500kms) so I might as well change them all and Nankangs are looking like the replacement.
Thanks again,
Jeffneil

Wildcard, I am nearly ready to order my new tyres after the last track day. I am really curious about these tyres in the wet. Hows the weather been up there recently? Able to give some feedback on wet weather handing?

Not having a go, just pointing out that its not necessarily an obvious answer
Rim Size | Width | Profile | Rolling Radius
18 225 45 659mm
18 235 45 669mm
18 235 40 645mm
18 245 40 653mm
When you consider that you are allowed a 14mm margin on the Rolling Radius, it looks to me to be an even bet on 40(-14mm)/45(+10mm) in the 235s but 45's would be closer.
But for my money the 245/40's are a closer match (-6mm).
All of these are allowable on the 8" rim.

None taken Andrew, it's just those with '03 cars have done all those calcs with the first change of tyres and 235/45s is a pretty rare size in 18", if it exists at all (probably as rare as 225/45 
)
)
