The original tires for the DMC are Goodyear NCT 195/60HR14 (front) and Goodyear Eagle GT 245/60R15. I've been unsuccessful in trying to find exact replacements of the originals. I've been able to locate another brand of tires for the front that are H rated. However, it's been a challenge to locate replacement tires for the rear that has the same speed rating. Is having a different speed rating (front and rear) a problem? Should I go with a different size tires to have match up the speed rating on the tires? What would you guys recommend as replacements tires? I would prefer to get the originals if that was possible. Terri
