standerd bolts are long enough but they slip straight through the cossie holes... get your ass to fords and order 16 escort cossie wheel studs and bolts...

drill out your hubs through original holes to the size of the studs and bash them in .... hey presto you now have studs and bolts that fit..

and ive just fitted 195's to mine think they look rude bit wont be doin any agressive corners lol
