I had a Jeep many years ago that I wanted to put larger tires on. I took it to the tire dealer that I usually do business with and explained what I wanted. The manager said no problem (eager to make a sale). Those tires never left the parking lot on my Jeep. I backed it out of the bay and turned the tires hard to one side and immediately heard the scrunch/rub. I drove it straight back into the bay and ask for the manager that told me they would work. I left there with my old tires remounted and balanced and never went back. Forum readers may not have all the answers/info you need, but a tire man should know his business. Good luck.
