Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Has anyone actually purchased a set of these so called "direct bolt on" Boss 338s yet?

I was about to say this! Mine would have directly bolted on to my 1991 with the right tire sizes.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
anybody running 305/35/20 tires in the rear? I just bought a used set of Pirelli and I am going to try it. Granted i have my fenderwells and bed floor out so I am not worried about rubbing there. I am worried a little stretching that wide of a tire on a 10in rim. We will see. I hope they work because it should look pretty cool.
Now i just need to buy some rims.

The wheels will fit fine. The tires are what hits. That doesn't mean the wheel company is at fault because we pick tires bigger than what we should! My wheels had only a small issue. That was fixed in about 10 minutes. The center cap would go on but I was affaid it may pop off during the ride home so we shaved just enough off each spindale to satisfy me they wouldn't and they didn't.
The wheels fit fine. Why everyone is making this into something it isn't I don't understand. If you don't want the tires to scrub buy orignal wheels and narrow tires issue solved. ![]()

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
The earlier versions of the these wheels WILL NOT work the 1.250" wide rotor without modifying the nose of the rotor. The center cap still wouldn't fit on some even after making the wheels fit. They do fit the light duty 1" wide rotor/spindle combination. Also the backspacing is an issue on the rear.

You must have 1" rotors...not 1 1/4" like most have...they don't fit the standard rotors...

Measure the thickness across the diameter.

OK,
thanks. I had to put a 1/4" spacer on the back but that was because of the tire I chose not the wheel it self. I like the wheels. In the picture you can see where the hub was grinded just enough to fit. ![]() ![]()

Ha. The fact is,... these wheels were designed for the 88-98 Chevy/GMC trucks. We as consumers tried to make them fit on our 60-87 designed suspensions/trucks. Boss Wheels was so close to hitting a "home run",... and they didn't even know it. At least Coys Wheels added a few more backspacing choices to their wheels. It's a shame an AMERICAN made wheel company (like AE/Boss) can't listen to the consumer.

41 pages in my view. Probably depends on how many posts per page you have set in your preferences.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
I got a set too, 20x8.5s all around with 255/45/20. I ground the front rotor nose and used 1" spacers in the back. I may not have needed the spacers in the back, but with the narrower track width of the rear compared to the front, it looks better with the spacers anyways.
