we need more info before we go recommending you a tire. i mean i can recommend you a great tire, but it might not be a great tire for you/her... see the thing about tires is there is no one that is best for everything. though there are some good all around tires, they may not be in your price range, or they may not for your application/needs. so first off we need to know the size of tire you are looking for, then we need to know what your are looking to get out of the tire, do you want a long life tire for the hwy or are you looking for a maximum traction tire for the mud/clay and sand? or do you want a all terrain tire that will kinda be a mix? -how much time/percentage of driving do you actually take it off the road and into the mud or sand? do you want a tire that will give you comfort over traction/ability? and lastly we need to know your budget. are you looking to spend under $800 or can you spend $1200 -the more you can spend the more options you will have. remember that tires are the final say in traction, weather thats just dry roads, or rainy wet roads, or mud, -you can have all the power in the world but if you cant get traction it does you no good, same with brakes and cornering, you can have the best of the best, but if you have crap tires, then none of it will matter. not saying you need to spend $1500+ on tires, you can find a good set for around $1000(installed out the door) -thats on the main land so HI might be a bit more. but yeah imo tires are one thing you dont want to cheap out on, trust me -you can have balancing issues that will shake the whole truck cause the tires are not round, or other issues with cheap tires and if you are only replacing tires once every 4-5 years, thats only $200-250 a year for tires divide that by the 4 tires and you are at $50 a tire a year. thats as cheap as an oil change almost. so just some food for thought. let us know what you are looking for in tires and we can be more helpful, again i dont want to tell you "go buy ______ tires and youll love them, they are awesome..." and you hate them because its not what you wanted or something.
