Making the jump to 35 sxs tires is one of those upgrades that completely changes how your machine looks and handles on the trail. It's a massive step up from the stock 28s or 30s that most rigs come with, and honestly, once you see a side-by-side sitting on 35s, it's hard to go back to anything smaller. But as cool as they look, there's a lot more to think about than just the "cool factor." You're moving a lot of extra weight and changing the geometry of your ride, so you've got to know what you're getting into before you drop a couple of thousand dollars on a new set of rubber.
Why Everyone is Moving to 35s
The most obvious reason people are obsessed with 35 sxs tires is the ground clearance. If you're tired of hearing that gut-wrenching "clack" every time your skid plate meets a rock, 35s are the answer. That extra inch or two of lift you get just from the tire diameter makes a world of difference when you're navigating technical rock gardens or deep ruts. It's the difference between walking a line and getting high-centered and needing a winch.
Beyond just the height, 35s give you a much larger "contact patch." Because the tire is physically bigger, there's more rubber touching the ground at any given time. This translates to better traction, especially if you're running lower air pressure. When you're trying to claw your way up a slick rock face, having that extra surface area can be the deciding factor in whether you make it up on the first try or end up sliding back down.
Plus, let's be real—they look aggressive. A Pro XP or a Maverick X3 sitting on 35-inch tires looks like a miniature monster truck. It gives the machine a presence that stock tires just can't match. But while the aesthetics are great, the performance gains in the rocks and mud are the real reason this size has become the new standard for serious trail riders.
The Hidden Costs of Going Big
I'd be doing you a disservice if I didn't mention that 35 sxs tires come with some "baggage." You can't just slap these on a stock machine and expect it to live a long, happy life without some help. These tires are heavy. Depending on the brand and the ply rating, you could be adding 15 to 20 pounds of rotating mass per corner. That's a lot of extra work for your engine, but more importantly, it's a lot of stress on your drivetrain.
First off, your belt and clutch are going to feel it. If you don't do a clutch kit, you'll probably notice your machine feels a bit "sluggish" off the line. The gear ratio is effectively taller now, so the engine has to work harder to turn those big tires. A good clutch kit will help you get that "snap" back and, more importantly, save your belt from smoking when you're trying to crawl through the slow stuff.
Then there are the axles. Stock axles are usually designed for 30-inch tires. When you jump up to 35s and start bouncing through the woods, those stock axles become the "fuse" in your drivetrain—meaning they're the first thing to snap. Many riders who move to 35 sxs tires eventually upgrade to heavy-duty aftermarket axles just for the peace of mind. It's one of those things where you might be fine for a while, but eventually, the physics of those big tires will catch up to you.
Matching the Tread to Your Riding Style
Not all 35 sxs tires are built the same. You really need to think about where you spend 80% of your time riding. If you're a desert person who loves high-speed washes and hardpack trails, you want something with a tighter tread pattern. Tires modeled after truck tires (like a BFGoodrich or a Maxxis Liberty) are great for this. They offer a smooth ride, they last a long time, and they don't wander at 60 mph.
On the flip side, if you're a "muderator" or you live for the deep woods of the Southeast, you need some lugs. A 35-inch mud tire is a beast, but keep in mind they can be rough on the ears and the spine when you're on a hard road. The vibration can be real.
Most people end up looking for a "hybrid" or an "all-terrain" style. Something with enough gap between the lugs to clean out mud, but with a flat enough profile to handle rocks and hills without feeling like you're riding on square wheels. Look for tires with good sidewall protection, too. When you're running 35s, you're often airing down to single-digit pressures, and you don't want a sharp rock poking a hole in your sidewall three miles from the trailhead.
Do You Need a Lift?
This is the big question. Can you fit 35 sxs tires without a lift? The answer is maybe. It really depends on your machine. Some of the newer wide-body turbos can fit 32s or even 33s bone stock, but 35s usually require some help. You might be able to get away with just cranking up your preload or adding some high-clearance A-arms, but a lot of guys find that 35s rub the inner fenders when the suspension is fully compressed or when the wheels are turned all the way to one side.
High-clearance A-arms are a fantastic mod to pair with 35s. They don't just give the tire more room to breathe; they also give you even more ground clearance. If you're really serious, you might look into portal gear lifts. Portals are the "gold standard" for running 35s because they provide a gear reduction right at the hub, which takes the stress off your transmission and axles while giving you a 4-inch or 6-inch lift. It's an expensive route, but it's the "right" way to do it if you want to keep your factory performance.
Wheel Choice and Offset
When you move up to 35 sxs tires, you're probably going to need 15-inch wheels. While some 35s exist for 14-inch rims, the selection is much better for 15s. Plus, a 15-inch wheel gives you more room for larger brake calipers if you ever decide to upgrade your stopping power—which isn't a bad idea, considering you're trying to stop a lot more weight now.
Pay attention to your wheel offset, too. If you go with a wheel that sticks out too far (a wide offset), you're putting even more leverage on your wheel bearings and ball joints. It'll make the machine wider and more stable, but it increases the "scrub radius," which can make the steering feel heavy or jerky in the rocks. Try to find a balance that keeps the tire centered over the hub as much as possible while still giving you the clearance you need from the shocks and tie rods.
Final Thoughts on Going Big
Switching to 35 sxs tires is a commitment. It's not just a "set it and forget it" kind of thing. You'll need to check your tie rods, ball joints, and wheel bearings more often because they're all working harder now. You might find yourself cleaning your radiator more often because the engine is running a little hotter under the extra load.
But man, once you're out there on the trail, it feels worth it. Rolling over a ledge that used to require a spotter and three tries feels like nothing. The confidence you get from that extra clearance and grip is addictive. If you're willing to do the supporting mods—the clutching, the axles, and maybe a little trimming—moving to 35s is easily one of the best ways to level up your off-road game. Just be prepared for everyone else in your group to start asking you to lead the way through the tough stuff!
