Yes, they are the same. I went with a slightly smaller front tire because it did rub on the inner fender a touch. The only thing close on the front are the brake lines at full lock. I wrapped those with wiring loom just in case but no issues.
The wheels are the Rambler U111 if that helps. Link below....scroll down a bit and click on the 18" tab
