I know the stock Boss rear tire is 285-35-19
anyone look at the widest tire that'll will fit our 9.5" rim?

I started to play with this website, but could not find anything

I personally wouldn't go any wider than a 285. Go with different wheels if you want larger tires.

 

I don't see why you would need wider rear tires on the Boss. The car was designed with handling as its primary characteristic, and changing the tire sizes will change how it handles.

Additionally, with a 9.5" wheel, I don't know of a wider tire than 285mm that will be certified by the tire manufacturer to fit. All 295mm tires need 10" wheels.

Are you looking for wider for drag racing, street, or track?

 

Go with the BFG K force 295
I had them on my Vette and loved them!

 

not sure about just using 9.5's but Peteinct is running 18 9.5 285/35 front and 18 10.5 305/35 rear,....rims I think they are Enkei PFO1's. he seems to like this combo alot, specialy the smaller rims.
