Thanks Nemesis, just got off the Phone with Bob @ HOW, he said 19x12 would not work right. So I ordered 19x10 & 18x9.5.

Bfg Kdw2.
I want to go with 295/35/19 & 275/35/18 but the tires or 27'' overall compared to 26.1 stock (rear), do you think I will have to recalibrate my speedo? Or have any problems with traction control?

Manual corvettes never need the speedo corrected because of the locataion of the sensor. Automatics on the other hand do need to be corrected like any other car.

Do you think i'll have any traction control probs?

You won't have any problems with those sizes. I ran them before getting new tires. I actually prefer the stance/look of those sizes, but I wanted wider tires, and had to go with 30 series on the rears, which are about 1" shorter.

Sorry to ask a rookie question; what is the driving experience like?
Do you notice a better hook-up from a dead stop? Better all around traction? Noticeable higher speed obtained in first gear?
Thanks for sharing the pics!

Ive had many different size rear tires (275/40/17, 295/35/18, 305/35/18, 315/35/18, 315/30/18, 335/30/18) on my car and referenced most on the dyno all correct without changing anythinig. The speed sensor is in the diff and takes it reading from there and actually calculates and makes the correction. If you dont believe go pay someone to change it for you.

Okay, help me understand then. You say it makes a correction?? How does it know there's a correction to be made and what's the reference point to make this correction?

the sensor reads how fast the pick-up is turning in the rear end and makes the correction. Like I said Ive been through it, I even had a different dear ratio at one point (4.10's) didnt have to change anything. I worked for a Corvette performance shop for the last 3 years so I dealt with this stuff on a daily basis.

You're saying the VSS and/or PCM are capable of detecting not only what size tires you are using, but also the differential gear ratio?
There are also people that work at NASA who are not qualified to explain how the space shuttle works. When you PROVE me wrong, I will publicly apologize for questioning you.

Why would you perpetuate this kind of misinformation?

Speedo readout is simple. The displayed result is simply due to mathematical multiplication of fixed gear sizes being turned at any speed. If the OD of the tire changes or the gear ratios are changed, the speedometer will read incorrectly.
It really cant work any other way. Without ground or satellite based reference points for speed, speedo results are calculated on board using known values such as tire circumference and known distance for a statute mile. If either of these change then your speed value will change. Since the statute mile wont ever change but tire OD or circumference can, that is the only variable related to tires which can cause speedo errors.
