P-Metric vs. LT-Metric (What to Know)
- P 275/55R20 (SL/XL): Best ride comfort and fuel economy for daily use; many trucks specify XL for stability and load.
- LT275/55R20: Stronger casing for frequent towing/off-road; offered in Load Range C/D/E and typically requires higher PSI for rated load.
- Always match your door placard: Size, load index/Load Range, and speed rating must meet or exceed OE.
Great Fits & Use Cases
- Highway/Touring (H/T): Quiet ride, straight-line stability, and long tread life for commuters and road-trip duty.
- All-Terrain (A/T): Open shoulders and biting edges for gravel, dirt, and light mud while staying civil on pavement.
- All-Weather (3PMSF): True winter-rated traction without seasonal swaps—ideal for regular snow.
- Winter/Snow: Maximum snow/ice grip in sustained cold; swap back when temps warm.

FAQs: 275/55R20 Tires
Can I switch from SL to XL in 275/55R20?
Yes, if your door placard calls for XL or you want added load capacity/stability. Always match or exceed the placard and adjust PSI accordingly.
Should I choose P-metric or LT for towing?
Frequent/heavy towing or work use often benefits from LT275/55R20 (C/D/E). For daily comfort and efficiency with light loads, P-metric (often XL) is ideal. Follow your placard.
What tire pressure should I run?
Use the door-placard PSI as baseline. LT tires typically require higher PSI to carry the same load—ask us for vehicle-specific guidance.
Will 285/55R20 fit as an upgrade?
It’s wider and slightly shorter; clearance depends on wheel width/offset, suspension, and liners. We’ll check your exact setup before recommending.
Which tread type should I pick?
H/T for quiet highway manners, A/T for mixed on/off-road, all-weather (3PMSF) for snow without swapping, or winter for maximum cold-weather traction.
