How Big can I go

How big of a tire can i put on a stock TA Hurricane rim right now only got 245's on would like to go to a 265 or 275 will it fit?

The problem isn't "what will fit" on the stock 16x8" wheel, its "what is available"? The largest "high performance" street tires I'm aware of are the 255/50-16's. Anything else is going to be a track only tire (Hoosier DOT Radial), or a lower line tire like the BFG Radial TA all-season. And most of the BFG's are a huge diameter that you probably wouldn't want on the car. Even the Hoosier 275/45-16's require at least an 8.5" wide wheel.

The largest and widest tire I found for my 16x8 rims
was the BFG Sport. 255-50-16. Approx 9.5 wide and
26.1 diameter for the rear.
245-50-16 BFG KDWs for the front as the 255s have been
known to rub, especially on a lowered car.:(
The 245s are about 8.7" wide and 25.7 in diameter.
Dunlop also makes a similar 255-50-16 tire.

HTH;)
