Default Anybody running 345/25/20 on a Grandsport or z06 ?

Hello everyone,

I came across these wheels from a friend. I am a completely stock 2013 grand sport, no suspension mods. He has taken them off his c7 zr1 and they are a compelling deal. I would like to know if anyone is running this in the rear without problems so I can pull the trigger ? I believe these are the exact wheels and the size is 345/25/20 rear. If anyone has c7 zr1 wheels on a grandsport or z06

c6 please show some photos. My second question is has anybody ran a 345/30/20 to add more sidewall or even a 325/30/20 ? https://www.corvetteguys.com/product...=8943668822052

Thank you sir, I have been using that calculator since 2005 lol. Awesome tool. The 345/30/19 seems to be a little bit larger than the 345/25/20 according to the calculator if I am not wrong.

badass7, Just my opinion , but I just dont like the skinny short side wall (25aspect) on such
a large tire and that why I chose to use a 345/30 on my 19x12.5 Wheel.......................

I know your car your choice your wheels

It's all good my Corvette Brother.............

Chuck, a 345/30/20 is 28.15'' OD which is too tall and would most likely rub if lowered.
I'm running the same Toyos as badass and slammed with no issues besides having no traction.

Hah, werrrrrrd. Very nice Mine was slammed for several years. Just recently raised her up a tad. Either way I never rubbed either.

I think the purpose of this thread was to show the OP that he can definitely run that size wheel with no problems at all as he has an opportunity to snag that set of wheels at a great price is what I gathered from his post.

Hoped our replies helped make your decision OP. Cheers to all........😎✌️

Absolutley. I am just trying to see if the 345/25/20 will fit on rear with no issue since thats on the wheels currently. Also wanted to know if anyone had tried 345/30/20 with no lowering or rubbing...
