Try not to use 60 series tires on 6 inch rims. I've got 235-60-14's on the back and there is little sideways stability. I can push on the car at the back and it moves easily back and forth. The 70's in the front don't do that. When I first put them on I noticed a weird sensation when going around corners. I can't wait to replace them when I have some extra cash. Luckily I got them cheap from a friend.

I think the best size for 14X6 wheels is 215-70-14 if you can find them. The 205-70-14's on the front are a little small looking but are actually close to the stock size. I put 225-70-14's on my 69 goat which are readily available in TA's. They might look a little big on a bird.

My 2 cents...
