Need help deciding on tires. Ran over an industrial sized nail and the old tires are too worn to just add another new one.

I know which ones im picking out, but what is the best set up.

I currently have 245/45/18 on a rims that is 18X8.5

Im debating between:

245/45/18
245/40/18

I have no suspension drop.

 

245/40, its a chceaper size, and you have less a chance of rubbing depending on your offsets.

or, roll ur fenders, and run 245/45 all day long and love the ride
