Without any specific tire pliers, good luck with the mounting, unless you have the beadlock type wheels. Getting the lip of the tire over the rim which is wider will be difficult by hand for sure. Spend the little $12-15 each and get them mounted.
You could also check with Walmart. Drop them off, pick them up later several hours. Mounting is $10 each, balance, they should be able to balance up to 35" tires as they sell that size under special order. Yah, just another option.
Finally, check with others in the local clubs. They tend to purchase their tires from a reputable shop that will balance them also. Sort of a hang out shop. Most clubs have discounts at such places.
