Yokohama Geolandar X-MT G005 37x13.50R17 121Q E-Load Mud-Terrain Tyre

Conquer mud, rock and ruts with Yokohama’s extreme mud-terrain — the Geolandar X-MT G005 in size 37x13.50R17. Built for hardcore off-road use with reinforced sidewalls, deep shoulder blocks and a self-cleaning tread, the G005 delivers dependable traction where AT tyres give up — while remaining predictable on wet British tarmac when you need to get home.

This 37-inch flotation size suits serious builds that need extra diff clearance and a wide, stable footprint. Pair with robust 17x9 or 17x10 wheels (see guidance below) and appropriate gearing/arch clearance for the best results.

Key features

• Extreme mud-terrain pattern with high void ratio and self-cleaning lugs for traction in clay, bog and deep ruts.
• Reinforced construction with multi-ply sidewalls and full nylon cover to resist punctures and impacts.
• Optimised block pitch helps manage on-road noise for a liveable drive between lanes.
• Durable tread compound designed to balance cut resistance off-road with mileage on road.

What’s included

• 1 × tyre (37x13.50R17 Yokohama Geolandar X-MT G005).
• Wheel not included. Valve, TPMS, balancing weights and fitting are not included.

Technical specifications

FAQs

1) Is this tyre road-legal in the UK?
Many sizes are E-marked from the factory; always confirm the sidewall marking for your specific tyre and ensure load/speed ratings meet your vehicle’s requirements.

2) Will it be noisy on the road?
It’s an aggressive mud-terrain, so expect more noise than AT/H/T patterns. The G005 uses varied pitch blocks to help control noise versus older MT designs.

3) What wheels work best?
Use 17" wheels within the approved width range (8.5"–11"). 17x9 or 17x10 is common on 37x13.50R17, with a suitable offset to clear arches and suspension.

4) Do I need to re-gear?
37s significantly change effective gearing and speedometer readings. Many builds benefit from re-gearing to restore drivability.

5) What pressures should I run off-road?
Start around mid-teens PSI off-road (vehicle-dependent) and adjust for terrain; always reinflate before road use.

6) Is 7.50R16 X-MT G005 available?
Yes — also available in the UK (listed separately on ofm4x4.co.uk).
