Running Square - wheels and tires

[2001ultima]

Are there any opinions on running a set of the same size wheels and tires front and rear to obtain optimum handling? Say we modified the front to fit a 305 or 315 tire and then run that same size in the rear.

Or would you still prefer to have the larger 335 in the rear?

Opinions would be appreciated.

Lee, Good to hear you opinion. Thanks. Jim

All good perspectives, thanks. The start of the thread was a proposal to run 305s or 315s front and rear, size width limited by the front space limitation. Some Ultima owners have fitted 295s. Some have fitted 19 inch as well. My idea was for a track setup to better balance the car. The car is light and I have ~450 HP and am looking for the best track setup. I was hoping someone may have had tried this track setup.

Yes, I would agree for a top speed run, a narrow front tires with lots of air pressure and the tallest rear tires would be best and for a 700+ HP Ultima than the widest rear tire would be best.

I track my car and am planning a new set of wheels so I thought I would see what people thought. It doesn't seem like anyone has run a setup like this. I am definitely going to increase the front size to 295s minimum. Maybe 295s front and 335s rear are better then 305/315s front and back. Or maybe there is no noticeable difference. I'll keep you posted.
