I want to place Goodyear polys on my mustang...I have 15inch wheels and I was going to get f60x15 all round I believe these equate to 235/60/15 BUT I would really like to stagger them with G60x15...but my car came with RWL N/S...the F60x15 no issues but the G60x15 do not come as a N/S tire...so having size on the rear and no size on the front would look weird any suggestions, or do I just come to grips it will have to be F60x15 all round
