what if I got 1.2 in wheel adapters?
It wouldn't matter. Its the
width of the rim that is giving you trouble. a 9 inch rim is generaly considered too wide the stock sized wheel wells on a 65-6 mustang. The most popular larger size I have seen on the front of mustangs is 17x8 with 4.75 bs and a 225 45 17 tire....this tire is exacly 9 inches wide, and generally goes in without rubbing. Some people have then stepped up to the next size (myself included) and put on a 235 45 17...which is about 9.5 wide. Some people have had to roll to fenders and some people have no and that is due to 1. flactuations in actual tire width from manu to manu and fluctuations in sheet metal and
suspension setups from car to car. While the 235 can be forced onto a 9 inch rim, even then, the wider rim, will square out the sidewalls making it more prone to hit the fender and or rub the inners. On a 9 inch rim, you generally talk about mounting a 255 or wider tire which is downright impossible to mount in the front without fender flares.
On the rear, again the most popular size I have seen is 235-245 45 17 on the 17x8 rim. Now since I run a 255 40 17 on the rear of my mustang and only had to roll the fenders, I have no doubts that you 'could' use a 9 inch rim in the rear with the proper spacers but it becomes a hassle trying to match the front and rear rims. Furthermore, adding a large
bolt on spacer holds the wheel further away from the drums and/or disc leaving the spacer eacily seen and producing a less than attractive look in my opinion.
What price are you looking at for these wheels? I bought my 17 rims at a car show/swap meet for $800 total and that was with valve stems, lugs, and locking lugs. I often see late model wheels for very similar pricing so I saw little need to even consider them.
