Wheel size TCS

[Spacecar]

hello, I just bought a 1991 NSX which had 17 wheels at the rear and 16 at the front and which I don't like
I received with the car the original rims on which I mounted Yokohama in original size
with the big wheels no problem
but with the origins my tcs turns on and the car loses power
Could one of you have an explanation?
I thank you in advance

Please state the EXACT front and rear tire sizes (for example, 205/45-16) you are using on each set of wheels.

On the big ones :front 215/45/16
Rear 245/40/17
On the originals :front 205/50/15
Rear 225/50/16

Well, those are the standard sizes (sorry for checking, but some folks end up with very odd tire sizes).

If the TCS and power drop only happens under strong acceleration, maybe the new tires still have their mold release on- new tires are actually pretty slippery at first.

If it happens all the time, Maybe a wheel speed sensor was damaged or disconnected while they had the wheels on and off.

Other than that, I'm out of ideas, sorry!

The 16-17 setup is stock pre-facelift NA2 or NA1 type R sizes. Maybe the TCS computer was changed ?

I found the reason……
I made a mistake
The tire shop put 60’s on the front….
I didn’t double check
Thanks again

I checked on my paper……
And this morning i decided to measure the outer diameter of the tire
and I calculated that there was a difference of 1.2 percent between the front and the rear..... it was not possible...
