I went with the popular choice Thanks Anubis. 235'sThe bodies on most of our G's are not centered perfectly on the frame. Some people have done 255's but have frame rub. I chose 245's because the overall diameter is only slightly taller than the factory spec 215/65/15 tire. 235/60/15's are a popular choice because they are the same diameter as the 215's. Jump up to a 255 and they will likely rub, especially when cornering and will create that tractor tire look. They have a 27.1" overall diameter....Too big in my opinion but give it a try if you're OK with that look.
