i have just put on a set of rims that i got today, and on the way home my dsc,brake light and the traction light all came on... now the rims i bought do NOT have tpms but that usually throws a tire pressure light, right? every time i turn the car off they go away untill about 2-3 minutes into a drive. so from research i see that most of you just clean the sender/module or whatever its called but i feel its far to big of a coincidince that it goes less then 5 minutes after i installed the new rims.. any ideas?

 

what did you put on?

 

they are xxr racing 522. 18x8.5 +30 front, and 18x9.5 +25 rear.

 

no suggestions?

 

What size tires are on the rims? If there is a variance in tire outside diameter then yes you could have an issue with the DSC.

 

your tires all dont equal up to the same radius or turning radius.
I have this problem as well.

I'm at work but if you like i can explaine the problem in more detail via my iphone
feel free to call or text me.

PM me for the number. you probably experience this error after making a few tight turns but never on a straight away. just power cycle the car and it goes away.

I ignore mine but be warned DSC and traction control arent functioning when this error occurs.

 

^^ thanks so much il pm you now! but for reference i hav 225/40/18 up front with 245/45/18 in the rear.

 

Those tires have very different circumferences...much more than the DSC will tolerate

You would have been better with 225-45-18F and 245-40-18R if you needed to go staggered

 

^^ o ok so i should buy some 225/45/18 for the front?or would 245/45/18 be best, that way its not staggered?

 

The best would be 245-40-18 on all 4 corners...

Second best would be 225-45-18 that is stock

The 245-45-18 are too tall........

 

Get 245/40-18's all around. No issues will ensue.

 

GOTCHA! thanks everyone for the help

 

If your going to do a staggard fitment do it right. here are some sizes you can use that dont mess with the dsc and work. plus look really good

front size 225/45r18 rear size 245/40r18 <---good
front size 225/40r19 rear size 255/35r19 <---funky
front size and rear size 245/30r20 <---rubber band man
you can't stage the rear wheels wider on a stock RX8 in 20's without modding the body cause it will stick way out past lines. you would need a wide body kit or something. or unless you want to look like your driving a dune buggy.
