Bigger Isn't Always Bad: Should You Upsize Your Wheels and Tires in Arizona?

Heat, rocks, desert, sand, and high-speed highways – driving conditions in Arizona are far from ideal. It's no surprise that many drivers are considering swapping out their stock wheels and tires for something more aggressive and durable.

What Does "Upsizing" Really Mean?

Typically, it involves:

Larger wheels — for example, going from 16″ to 17″ or even 20″
Tires with a bigger profile and width — like switching from 265/70R16 to 285/75R17
Lift kits — to make space for those larger tires

These upgrades give your ride a tougher, more rugged look, improve off-road capability, and offer better protection from rocks and rough terrain. And let's be honest — they look cooler than a morning cup of coffee in Mesa.

Why Upsizing Makes Sense in Arizona

Drivers from Arizona on Reddit and local forums point out several reasons:

Heat + Asphalt — A taller tire profile can handle thermal stress and pressure better
Sand and Off-Road Trails — A wider contact patch = better traction
Gravel and Rocky Terrain — Wider, thicker tires mean less risk of sidewall damage
Style Factor — Some just want their truck to "look like a tank." No judgment

Downsides to Consider

Upsizing isn't just "plug and play." Here's what experienced drivers warn about:

Decreased Performance & Fuel Economy — More weight and rolling resistance = lower acceleration and more fuel stops
Suspension and Steering Wear — Especially if you don't upgrade other components to handle the extra stress
Tire Availability — Not all sizes are easy to find — especially if you're going 35″–37″
Will You Need a Lift? — Without one, your tires may rub against the fenders or suspension

When Is It a Good Idea?

Go for it if:

You frequently drive off-road, in the desert, or up into the mountains
You care about aesthetics and stance
You're ready to invest in quality parts — lift kit, suspension, and brakes

Skip it if:

You drive mostly in town or on highways
You're not comfortable increasing fuel use or modifying suspension
You're new to tire/wheel mods and want to keep it simple

Alternatives That Still Work

Slightly larger tires (one size up) — noticeable improvement without major changes
All-Terrain (AT) or Rugged Terrain (RT) tires — aggressive look, road-friendly performance
Reinforced sidewalls (C or D load-rated) — extra durability without new wheels

Wrapping It Up

Upsizing to larger tires and wheels is a smart move for Arizona drivers — if you know your goals and understand the added costs. It's a balance of functionality and style, but not always about everyday comfort. If it's your first time making these upgrades, talk to a mechanic or tire expert before jumping in.
