yes, my big *** 305/50-20's on Intro Pentia 8, 20x10's. IMO, thats alot of wheel tire to balance as well as they did.

they ain't cheap

 

But these are the GM silverado ss rims. They should be more true than most aftermarket rims. Oh by the way, on my factory 8.5" wide rim. what's the widest tire I can fit? I was hoping to be able to squeeze a 295-45-20. But looking at the mfg suggested size, it's stating the narrowest rim you can use on a 295 tire is a 9.5-11 inches. Would you agree or disagree with this statement?

 

On a 20x8.5" wheel you can fit a 305/50-20. That's a 32" tall tire.
And I beleive that's the Max. if you go by the tire mounting specs

 

I want shorter, and the 295-45-20 is the exact height I want 30.5 inches and NO TALLER. If you can squeeze a 305-50-20 on a 20x8.5 rim, you can squeeze a 295-45-20 just fine, right?

 

Nope, at least if you follow the wheel mounting specs.
The largest 30.5" tire rated for an 8.5" wheel is a 265/50-20 that I found.

 

Then it wont be as wide as as the factory tires even

 

It will be wider, section width on that tire is 10.9"

 

it'll be wider than a 275-55-20 tire even?

 

oh, my bad, 265/50-20 is the stock tire?

Those 305/50-20's would fit the wheel

 

No, section width on that is 11.1"

However the 275/55-20 is a 31.8" tire

that 305/50-20 is 32" and is wide as ****.
