Are 33-Inch Tires the Right Upgrade for Your Jeep Cherokee or Renegade?

Upgrading tires is one of the most impactful modifications you can make to a Jeep Cherokee or Renegade. While a set of quality all-terrain tires can improve daily driving, stepping up to 33-inch tires is a different league. It changes not only what your vehicle can do off‑road but also how it behaves on pavement, how much fuel it burns, and what modifications are required. Before you pull the trigger on a set of 33s, it pays to understand exactly what you’re getting into.

This guide breaks down the real-world benefits, hidden costs, and necessary upgrades for fitting 33-inch tires on a Jeep Cherokee (KL generation, 2014–present) and a Jeep Renegade (BU generation, 2015–present). Whether you’re a weekend trail runner or planning a full overland build, you’ll find the information needed to decide if the upgrade is worth it for you.

What Exactly Are 33-Inch Tires?

When we talk about “33-inch tires,” we usually mean tires that measure about 33 inches in diameter when mounted and inflated. In metric sizing, that often translates to something like 285/70R17 or 255/75R17, though exact diameters vary by brand and tread pattern. For comparison, a stock Jeep Cherokee Trailhawk comes with 235/65R17 tires (roughly 29 inches tall), while a Renegade Trailhawk sits on 225/60R17s (around 28 inches).

It’s important to note that not all “33‑inch” tires are exactly 33 inches. Some brands run slightly short, and others measure closer to 33.5 inches. Always check manufacturer specifications for the actual diameter and width. The tire’s width and sidewall stiffness also matter because they affect how the tire fits inside the wheel well.

Common 33-Inch Tire Sizes for Jeeps

  • 285/70R17 – 32.7–33.0 inches, widely used on Jeep Wranglers and Cherokees with the right offset.
  • 255/75R17 – approximately 32.1 inches, a narrower “pizza cutter” that fits better without rubbing.
  • 275/60R18 – roughly 31.9 inches, often a good option for Cherokee owners with 18‑inch wheels.

The key takeaway: “33s” is a shorthand. Always verify the actual diameter when planning your build.

The Benefits of Upgrading to 33-Inch Tires

Larger tires deliver concrete performance gains in several off‑road scenarios. However, not every benefit applies to every driving style.

Increased Ground Clearance

The most obvious advantage is extra ground clearance. A 33-inch tire lifts the lowest point of your vehicle (the differential or frame crossmember) by roughly 1.5 to 2 inches compared to the stock 29- or 28-inch tires. That extra clearance lets you straddle rocks, logs, and ruts that would otherwise scrape the undercarriage. For Jeep Cherokee owners, this is especially valuable because the KL Cherokee’s independent front suspension already limits articulation – any extra clearance helps.

Better Approach, Breakover, and Departure Angles

Larger tires improve approach and departure angles because the tire’s leading edge extends further forward and backward. You can drive up steeper ledges without the front bumper hitting, and you can descend steep drops without the rear skid plate dragging. The breakover angle also improves because the vehicle’s belly sits higher relative to the tire contact patches. For a Jeep Renegade, which has a relatively short wheelbase, this effect is quite noticeable on tight trails.

Enhanced Traction on Soft or Loose Surfaces

A wider and often more aggressive tread pattern (mud‑terrain or all‑terrain) gives you more rubber in contact with the ground. That means better grip in sand, mud, snow, and gravel. On the trail, a 33‑inch mud‑terrain tire like the BFGoodrich KM3 or Toyo Open Country M/T will self‑clean more easily in thick mud. For overlanders, an all‑terrain such as the Falken Wildpeak AT3W or Cooper Discoverer AT3 XLT offers a good balance of off‑road bite and on‑road manners.

Improved Aesthetics and Stance

Let’s be honest: bigger tires look aggressive. A Cherokee or Renegade with properly fitted 33s and a modest lift has a purposeful, ready‑for‑anything stance. For many Jeep owners, the visual upgrade alone is worth the price of admission. However, good looks should never come at the expense of safety or drivability – plan your build accordingly.

Major Considerations Before You Buy 33s

The downsides of going to 33s are real, and some can be expensive to fix. Here are the factors you absolutely need to evaluate.

Cost: Tires, Wheels, and Installation

A set of four 33‑inch tires typically costs between $900 and $1,800, depending on brand and tread type. If your stock wheels have insufficient backspacing, you may need new wheels ($600–$1,200). Installation, balancing, and disposal fees add another $100–$200. If you also buy a lift kit and recalibrate the speedometer, the total easily reaches $3,000–$5,000. For a Renegade, which requires more extensive modifications to fit 33s, costs can climb even higher.

Fuel Economy Loss

Larger tires are heavier and have higher rolling resistance. Expect a hit of 1 to 4 miles per gallon in combined driving, with most drivers seeing a 2–3 mpg drop. For a daily driver covering 15,000 miles per year at $4.00 per gallon, that’s an extra $300–$600 annually in fuel costs. Hybrid or diesel models are less affected, but the Cherokee and Renegade lineup is mostly gasoline‑powered.

Speedometer and Odometer Error

When you install bigger tires, the speedometer reads slower than you’re actually going. At highway speeds, the error can be 5–8 mph. This also throws off odometer readings, shifting maintenance intervals and potentially causing issues with warranty or lease terms. You can recalibrate using a programmer like the Superchips FlashCal or a dealer flash, but that adds $200–$500. Some shops also offer custom programming via the OBD-II port.

Suspension and Clearance Modifications

Jeep Cherokee (KL): Fitting 33‑inch tires under a KL Cherokee typically requires a 2–2.5 inch lift (spacer lift or full coilover kit) and trimming of the front inner fender liners. The independent front suspension has limited articulation, so a lift is essential to prevent rubbing at full suspension compression. Aftermarket upper control arms may be needed to restore proper alignment. Even with a lift, you may need to adjust steering stops or limit turning radius slightly.

Jeep Renegade: The Renegade is even more tricky. To clear 33s, most builds use a 2–2.5 inch lift plus aftermarket bumpers that are cut higher, and heavy trimming of the front and rear lower bumper sections. The Renegade’s strut‑type front suspension has very limited clearance. Some owners also install wheel spacers or aftermarket wheels with a lower offset to push the tires away from the frame. Without meticulous work, you’ll get rubbing on the lower arms and inner fenders.

Gearing and Powertrain Stress

Larger tires effectively lower the gear ratio. On a Jeep Cherokee or Renegade with the standard 3.73 or 4.10 axle gears, 33s reduce the effective ratio by about 10–15%. That means less torque at the wheels for climbing and accelerating, and the transmission will hunt for gears on the highway. Off‑road, you’ll notice the engine struggling on steep climbs unless you regear (e.g., to 4.56 or 4.88). Regearing costs around $1,200–$2,000 per axle and requires a skilled installer. Without regearing, the transmission and differentials endure higher heat and stress, potentially shortening their life.

Modifying your Jeep beyond factory specifications can void certain parts of your warranty, especially if a failure (like a half‑shaft break or transmission problem) is linked to the tire size. Additionally, some states have laws about maximum tire diameter beyond which the vehicle is considered “non‑compliant” for road use. If you have to pass a safety inspection, check local regulations. Many owners never have issues, but it’s worth knowing the risks.

Installation and Maintenance: Doing It Right

Once you’ve committed to 33s, careful installation and ongoing maintenance are essential for safety and longevity.

Professional Installation and Alignment

Mounting and balancing 33‑inch tires requires heavy‑duty equipment. Take the wheels and tires to a reputable tire shop or off‑road specialist. After installation, a professional alignment is critical – improper alignment causes rapid wear, poor handling, and potential vibration. Expect to pay $100–$150 for a quality four‑wheel alignment.

Lift Kit Selection

For a Jeep Cherokee, a 2‑inch spacer lift is the most affordable route ($300–$500), but for best ride quality and clearance, a full coilover or strut replacement lift ($1,000–$2,000) is better. For a Renegade, spacer lifts are common, but they can stiffen the ride. Many owners also install aftermarket bump stops and extended sway‑bar links to keep components within safe range.

Trimming and Clearance Checks

Expect to do some cutting. For both vehicles, the inner fender liners in the front will need to be trimmed or removed. The Renegade’s bumper end caps often require cutting as well. After installing the tires, cycle the suspension fully – jack up each corner to simulate max compression – and check for rubbing. Use a heat gun to push back plastic parts if needed. Always run the tires at the recommended psi for load; overinflating can cause center‑tread wear and reduce traction.

Regular Tire Rotation and Pressure Monitoring

Rotate tires every 5,000–6,000 miles to promote even wear. The larger and heavier the tire, the more important rotation becomes. Buy a good tire pressure gauge and check pressures weekly – underinflation on a 33‑inch tire can lead to overheating and blowouts. If you off‑road frequently, consider a portable air compressor to adjust pressures on the trail (typically 15–20 psi for loose sand or rocks).

Inspect Suspension Components More Often

With larger tires, ball joints, tie rod ends, and wheel bearings wear faster. Plan to inspect these parts every oil change. Look for torn boots, play, and unusual sounds. Upgrading to heavy‑duty ball joints (like MOOG or OEM+ parts) can extend service life.

Alternatives to 33-Inch Tires

If 33s seem too extreme or expensive, consider these options:

  • 32‑inch tires (e.g., 265/70R17): Often fit a Jeep Cherokee or Renegade with a 1.5–2 inch lift and minimal trimming. They boost clearance and capability without the major costs of regearing or heavy trimming.
  • 31‑inch tires (e.g., 245/75R17): These fit many KL Cherokees with just a leveling kit and offer a nice balance of off‑road utility and daily drivability. No regear required.
  • Stay with stock size but upgrade tire type: A premium all‑terrain tire (like the BFGoodrich KO2 or Toyo Open Country AT3) in the factory size provides better grip and durability than the stock highway tire, without clearance issues.

Final Verdict: Are 33-Inch Tires Worth It for Your Jeep?

For a Jeep Cherokee, fitting 33‑inch tires is a significant project that requires a lift, trimming, and ideally a regear. The payoff is real: better clearance, more aggressive looks, and the ability to tackle tougher trails. If you off‑road a few times a month or more, the investment can be worthwhile. For a daily driver that rarely leaves pavement, the fuel penalty and additional wear may not justify the cost.

For a Jeep Renegade, the challenge is greater. The Renegade’s suspension and body design make it harder to clear 33s without extreme cutting. If you must have 33s and are willing to do the work, you’ll have one of the most capable small Jeeps out there. However, many owners find 31‑ or 32‑inch tires to be a more practical limit for moderate off‑roading.

Before making a decision, look at what other owners have done. Browse forums like Jeep Cherokee Club or Jeep Renegade Forum for build threads and real‑world feedback. Check out tire reviews on Tire Rack for exact measurements and user experience. And if you decide to go ahead, invest in quality parts and professional installation – your safety on and off the trail depends on it.

In the end, the 33‑inch tire upgrade is a truck‑level modification for a crossover‑based platform. Do it for the capability and the look, not for the fuel savings or easy install. When done right, it transforms your Cherokee or Renegade into a true trail‑ready machine.
