I currently run a 295/30/20 on factory Z51 wheels. It’s .2” larger overall diameter when you size up from a 285 to a 295, 26.8” to 27”. I know some have run a 305. That will increased the diameter to 27.2”. I believe you could go wider with aftermarket wheels. For the track I stick with the stock sizes.

I run 295/30/20’s rear, 255/35/19 front. I would have tried 305/30/20’s & 265/35/19’s if they were an option for the tires I went with. I’m running firehawk Indy 500’s and have been very happy with them. I prefer them over the OEM tires and the price could not be beat at under $800 for the set installed.
