New wheels just want to double check tire sizes

[Silverbullit99]

Hi guys,, I just picked up a set of C6 wheels for my 1999 C5.
What I had was 17/18. The new ones are 18/19. There shouldn't be a problem with these on my car right?

Corvette C5 tire size was
17 Front 245/45/17
18 Rear 275/40/18

Now on these C6 wheels I should use this size of tires.
front should be 215/45/18 or 225/45/18
rear should be 275/35/19

C6 wheels 9 1/2" Front 11" Rear wide will these fit the C5

this size of tire can also be used..
18 Front 245/40/18
19 Rear 285/35/19

I just want to double check what I dug up, any thoughts about these sizes ?
ALSO .. the TPMS from my old rims should fit on these ..??

These are the rims..

215s? Will these even fit? That sounds WAY off. That's more a mini-van size.

HI there,
I agree, stay with OEM tire sizes on those rims, 215 is WAY too thin.
Allthebest, c4c5

Looks like I should be using this size on those C6 wheels
18 Front 245/40/18
19 Rear 285/35/19

Also do you think spacers in the rear wheels will be required ??
Anyone know how thick ??
Then I'll need longer bolts too ..

And,, what happens to my original TPMS sensors ? will the old ones still work ? ... seeing that the tires are bigger ??
