Well if you can get the spindle lift you should be able to fit 305's. They're still just a 33" tire, but wider. Making the problem turning them at full lock. Mine fit perfect with no trimming, but just incase i trimmed just a wee bit from the front on each side incase i'm flexing some. And along with everyone else, i'd hold out for a better full set. For those tires thats not a bad price new, but for that particular set, pass on it.
Damn, I would have never thought a 305 would fit on a 7.5" rim. I'm running 275's on a 9" rim and they look rounded.
That's what I'm saying, your tires look pregnant. I can't imagine what a 305 on stock rims would look like. I'd be worried they'd pop off the rim.
