I am trying to figure out how/why my 2015 Corvette Stingray has 19" fronts and 20" rear wheel size. In standard equipment it says wheels are 18 front and 19 rear. I do have the 3LT package, but it doesn't say anything about the wheels being upgraded with that option. I also have the Z51 style spoiler that says it was dealer installed but the car isn't a Z51. I was expecting to see which "option" on my window sticker increased the wheel size and it isn't called out. Was this potentially something the previous owner upgraded?
Check your window sticker or RPO list (under the rear carpet, by the battery; be careful not to tear the carpet) for RPO code ZF1. This was the appearance package available for 2014 & 2015 model years and included tires, wheels and spoiler similar to the Z51.

So the window sticker doesn't say anything about wheel size except in the Standard Equipment section where it lists 18" front and 19" rear. The only thing in the "options" section that seems to be relevant is a $600 option that says "Z51 Style Spoiler, Carbon". I also checked the RPO list under the carpet and there is no "ZF1" code. Now I am further perplexed. Anyone know what else was distinct about the Z51 appearance package that I could check to see if I have? Maybe the dealer installed the spoiler and also added the larger wheels which might explain why it isn't listed in the RPO list?
NEW! ZF1 Appearance Package, includes (Q7S) 5-split spoke, Silver-painted aluminum, 19" front and 20" rear wheels, (XFJ) P245/35ZR19 front and P285/30ZR20 rear, performance summer-only tires and body-color Z51-style spoiler
What does the sticker in the driver's door say about tire size? Mine is a Z51 thou. When I was looking up the RPO codes there was a few different tire and wheel options. Looks like rpo code r87 or q7e or q7s maybe
