Somewhere between a trail build and a full swamp monster sits the 34 inch tire. It is tall enough to change what your side-by-side can climb over, but still realistic for a machine that also has to drive to the deer stand on Saturday morning.
The EFX MotoHammer 34×10-20 Tires on MSA M45 Portal Gloss Black Milled Wheels package includes four EFX MotoHammer tires, four MSA M45 Portal wheels, lug nuts and center caps.
Size breakdown
A 34×10-20 is roughly 34 inches tall and 10 inches wide, mounted on a 20 inch wheel. The bigger wheel diameter means a shorter sidewall than a 34 on a 14 or 15 inch rim. Riders often like that combination for steering response and a more planted feel, while still getting a big jump in ground clearance.
A wheel named for portal builds
The MSA M45 Portal is finished in gloss black with milled accents. As the name suggests, it is a wheel riders commonly pick for portal gear lift builds. Before ordering, check that the bolt pattern and offset fit your hubs, whether you run portals or not.
Planning for 34s
Most machines need real modification to run a 34 inch tire. That usually means a significant lift or a portal gear lift, plus attention to fenders, axles and clutching. Portal lifts are especially popular with tires this size because they add gear reduction, which helps the machine turn the extra diameter without overworking the belt.
Expect to rework clutching or gearing to get the most out of a 34 inch tire. Without it, the machine can feel sluggish and the belt may run hot. Planning the drivetrain along with the tires saves headaches down the trail.
What comes in the package:
- Four EFX MotoHammer 34×10-20 tires
- Four MSA M45 Portal gloss black milled wheels
- Lug nuts
- Center caps
Clearance and fit
Measure before you buy. Look at the space between the tire and your fenders, cab and suspension at full lock and with the suspension compressed. Confirm your bolt pattern and the offset that suits your hubs. If you are running portals or offset arms, that changes where the tire sits, so take it into account.
