I have the 29,s on stock ecco,s they are 9.3 Inch wide so your rubbing must be pretty minimal with your tire at 9.5 wide?
My tire fitter said 235 is the widest he would fit on my TJ which is one size above factory recommended max of 225 with my wheels, cant remember what the ecco,s are but I think they are 7 inch, wish I knew about the washer fix before the new tires or I would have gone 31,s, 30" x 15 are not very common in Australia and maybe the reason the 65ths came with ecco,s which is different to the US spec?
