Help, The installed the wrong size Tire today.

[ERicincal]

While at the tire shop, the attendent mis-heard what I said, and wound up installing a 255/45/17 tire on my car. (front size is stock 215/40/16- 80%wear)

I have read the posts at: http://www.nsxprime.com/ubb/Forum1/HTML/005742.html

and I am reading that changing the tire sizes can adversely affect the TCS. I was going around a turn today, not terribly fast, but as I accelerated out of the turn the TCS, was limiting my throttle inputs.

This may have been becuase the tires are new and were slipping, but I am wondering based on what I read, is this what happens when you increase the rear tire size? will this increased size continue to cause the TCS on during somewhat spirited driving? do you guys think I should I go get them replaced with the 245 /45 /17? and if I keep them, will the handling change? more understeer?

thanks for your help.

Keep the tires. On my stock NSX I have the same tire setup. And there is no TCS problem. You just cornered to fast. (and don't forget, 255 looks better than 245)

I also have the same setup (for the third set of tires in a row) and no problem at all...

 

[gheba_nsx]

Opps I misread the tire size: I have 255/40/17 and not 255/45/17. I do not know if that size is ok also...

255/45-17 causes problems with the TCS. 255/40-17 doesn't.

Sorry, I also misread the 255/45 for 255/40. You get indeed problems with your TCS if you use the 45's. You really need 255/40

Go back to the tire shop and try to change the tires for the right ones.

Hmm...it seems to me that the stock size for front wheels is 215/45/16 and not 215/40/16 !

You should have no problem base on the size you are telling me.

Look here for explanation: http://www.nsxprime.com/ubb/Forum1/HTML/005930.html

However, 255/45/17 is much taller than stock. It will hurt your gearing/acceleration.

TCS will not operate properly on a '94-01 with 255/45-17 rear and the stock 215/45-16 front. You'll need to get a different size rear tire (or else a different size front tire).
