Was told to post this question here. Traction Control issues
I was told this forum would be the best place for a technical question like this. Has anyone had issues with traction control kicking in after going up in wheel size? Old setup was 19’s in the back and 18s up front running 305/30/19 and 265/35/18. New wheels are 20’s/19’s running 295/30/20 and 255/35/19. On the old setup I had the car up to 165 with zero issues on a couple occasions. With the new setup it seems like every time I get to around 110-120mph the traction control wants to kick in. I still have yet to have the new TPMS sensors paired, is it as simple a fix as that? Anyone dealt with this issue before when bumping up to 20’s in the rear and what’s the fix? Besides turning TC off. Driving an ‘08 Z51 M6. When searching other threads on this topic I found a few that said it all depends on keeping your front to rear wheel diameter ratio in a certain range. General consensus of 1.04-1.06% seems to be the sweet spot. My rear diameter is 27” and front is 26” which makes my ratio 1.038%. Any one have any ideas?
