I'm running L60 Pro Tracs on the back of mine with but haven't driven it with them mounted yet. Looks like they will probably rub on corners w/o air shocks but luckily I do have a pair of those as well. I have seen one other car with L60 Goodyears and it looks really cool with the Goodyears. It is posted on TC forums

Don't know if Goodyear G or L 60's will rub when mounted on 8's so maybe Rusty can help you out with that. I would think G's are low enough profile so good chance those will work.
