Tire sizes for Boss 338 and pics

This isn't your year model but they have the rims and tires that you're looking for.

Re: Tire sizes for Boss 338 and pics

I really don't know what size tires to use with 20 inch rims. i am currently running 235-70-15 (27.95 in height) on the front and 275-60-15 (27.99 in height) on the rear.
So i am thinking of running 20x8.5 Boss 338 on 245-40-20 tires. Ii just don't know what size for the back if I ran the 20x10 Boss 338. I want a little bigger tire just for a slight rake or close to even ride.

295/40/22 rear

you can get 295/40/20 for rear if you go 20's all around....i went with coys to avoid the hub problem or running spacers.

Here's the thread that started in 2009.
Thru that time Boss modified the wheel to make them fit,... but they still didin't get it right.
All you have to do is grind the "nose" of the 1-1/4" wide rotors and they will go right on.
1" Light Duty rotors were a bolt on from the very beginning.
Look here:

Re: Tire sizes for Boss 338 and pics

This seems like more work than a little bit. I like the wheels but I am not trying to buy them for my truck and they never fit. I am confused right now on what I want to do. Are there any nice 20 inch wheels that directly bolt on with out any modifications.

5 minutes with a grinder (on each side) is all we are talking about.
