i have a set of 10" CL auto drags, that i have not mounted yet. my question is with my 1/4 inch spacer my BS is 4 3/4. will this work without hitting frame with a 275/50/15 drag radial, or should i stick with the 275/60/15 street radial? (i trimmed my molding around the inside fender so that should not be an issue to the outside, just concerned with the inside clearance).
