68 Skylark tire sizes
 

Hey everyone, Im new to the site and was looking to see if anyone could help me out. I have a 68 skylark and im trying to frigure out what tires i can fit under it. Its stock ride height. I have 15x7 rims 4" backspace for the front 15x8 4.5" backspace for the back. Id like to get as much meat under the car without rubbing or issues steering. Ive heard 235/60/15 and 275/60/15 would fit without any issues but would like a few more opinions on it. Also, id prefer not to remove the inner lip on the q.p if i dont have to. Any help would be awesome!! Thanks
