You don't want a larger front tire. Not only is the clearance a problem, when you get to the larger tires - you get tires that are built for big bikes weighing twice as much as the Savage.
You should pick a tire that you will wear out in 5-6 years or less, as the rubber loses grip as it ages. If you ride less then 2.000 miles a year by a less expensive tire that will wear out in 12,000 miles. If your ride 6,000 miles a year buy a more expensive tire that will go for more than 20,000 miles.
Here are the tire (pairs) that will fit the Savage.
