Corvette Guys Question
Corvette Guys Question Has anyone had an issue with the Active Handling when going to a wider rear tire than stock? for instance I'm switching from a 245/45/17 275/40/18 combo to a 245/45/17 295/35/18 combo.. was told that the traction Control may activate prematurely since the rear is wider than what came on it, but it's just a factory Z06 width for the rear.. I have an 04 Auto Coupe is it matters.. and if it helps the difference in the rear tire diameter is 0.68 going from a 26.7 to a 26.02
Mine does it, because the EBCM in the pre 2001's are pieces of ****. It's intermittent though. I have 295's on my 5 spokes, but it happened before the wider tires as well. The corvetteforum people think their cars are made out of gold, much more useful information on here honestly.

I've gone from, 18's to19's to now 20x12.5's.My traction control light has been coming on since 2005 no matter what size tires I've had own, I have over 156k miles on it now and just ignored the light. Good luck, L8R DFLASH

The only way I see it being an issue is you go to a shorter tire, it would make the car think it's actually spinning. Tuning should get rid of that issue I would think.
I have a 2001 z06 and ran 295 35 18's with 275 40 17's for 6 years with no problems. I was on the factory z wheels which are wider than then the coupe wheels. I also ran a 305 35 18 on the rear for a couple years. All this with no problems about active handling
Well I haven't had any issues. Even though the diameter difference is only .30 I just keep a 1 psi difference between the rears and front without being under or over inflated.. only problem I had was after the tires were on a sensor decided to wig out and not register the PSI which caused the computer to think I had a flat and cut the power down and limit it to 55mph.. temporary solution to that was to turn off the TPMS DIC until I get a new set of sensors.

Pre 2001 can't be sent in since they're not manufactured anymore. They changed the design in 2001 to where they're repairable. There's supposedly a fix for them now, but it doesn't happen enough for me to send it in. The only pre 2001 units that are repairable are the active handling ones as well, luckily mine has active handling
I ran 275s on the front (no issue and will be running them again later this year) and 305/35/18" on the rears without issues. (for op)
I wanted a C6, I really did. But I picked up my FRC with 39k miles for 16k, just couldn't pass it up. All the C6's were 05's with 100k miles for 18-19k, I'm sure there were some better priced ones, but couldn't for the life of me find any of them.
