Tire Sizing Effect on Time

[Paul Huryk]

We suggest you run as large a front tire as possible on a front-heavy RWD car. So if you can fit a 245 or 255 up front, go for it!

As most braking and all of the turning is done by the front tires, a larger contact patch has it's advantages on the street and track. Having a staggered tire setup can give mechanical understeer that makes driving fast pretty difficult.



If possible (like on the 3rd gen f-bodies we manufacture wheels for), we suggest as close to a "square" tire setup as possible - same size on all corners. A car will be faster (and easier to control) with 265 tires on a 4 corners than a 245/285 setup - even though the total tire width is the same.
