* Specific Ram model: Is it a 1500, 2500, or 3500? The larger the truck, the more likely you are to be able to fit larger tires. Even within these categories, there were variations in wheelbase and suspension.
* Lift kit: A lift kit is almost certainly required to fit significantly larger tires than what came stock. The height of the lift dictates how much larger you can go. A small lift might only allow for slightly larger tires, while a significant lift opens up many more options.
* Wheel offset and backspacing: The wheel's offset and backspacing will determine how much clearance you have inside the wheel wells. Incorrect wheel specifications can cause rubbing, even with a lift.
* Tire size and aspect ratio: The diameter of the tire is the most obvious factor, but the aspect ratio (the sidewall height) also plays a large role. A taller sidewall will increase the overall diameter more than a tire with a low aspect ratio and the same overall diameter.
Without knowing the specifics of your 1995 Dodge Ram (model, lift kit, etc.), it's impossible to give a definitive answer. However, you can do the following to find the answer for *your* truck:
1. Check online forums: Search forums dedicated to 1995 Dodge Rams (e.g., DodgeTalk, etc.). Members there will likely have threads discussing tire size upgrades and their experiences. Search for threads related to your specific model and any modifications you've made.
2. Use a tire size calculator: Several online calculators allow you to input your current tire size and the desired increase in diameter or circumference. This can help you estimate how much larger you can go without causing interference.
3. Consult a tire shop: A reputable tire shop familiar with older Dodge Rams can offer advice based on your specific truck and desired modifications. They can also help you choose tires that are appropriate for your driving style and conditions.
In short, there's no single answer. Research your truck's specific model and modifications to determine the largest tire size you can safely and legally install. Remember to consider the effects on your speedometer and odometer accuracy as well.
