RV Tire Pressure: The Complete 2026 Guide (PSI by Weight & Type)
RV Tire Pressure: The Complete 2026 Guide (PSI by Weight & Type) Set RV tire pressure by weight, not by the sidewall max: most RV tires run 65 to 110 PSI cold, and the correct number comes from your tire maker's load/inflation table after you weigh each axle — never just the maximum PSI stamped on the tire. A Load Range E travel-trailer tire maxes out at 80 PSI and 3,195 lbs per tire, but if each tire actually carries only 2,000 lbs, the table calls for about 55 PSI, not 80. Find your exact number in seconds with the RV Tire Pressure Calculator(/auto/rv-tire-pressure-calculator). I have weighed dozens of rigs at CAT scales, and the pattern never changes: owners inflate to whatever number is molded into the sidewall, then wonder why the center tread is bald at 12,000 miles. On my own 7,400-lb travel trailer, the four LR E tires...
How to Size a Bilge Pump for a 25-Foot Boat (2026 GPH Guide)
How to Size a Bilge Pump for a 25-Foot Boat (2026 GPH Guide) For a 25-foot recreational boat, size your primary compact centrifugal bilge pump at 2,000 GPH (rated) with a 1,000 GPH backup on a separate circuit — and remember that a "2,000 GPH" pump only delivers about 1,520 GPH once it lifts water 3 feet to the discharge fitting. That gap between the box rating and real output is where most owners get caught. Run your own breach scenario with our free Bilge Pump Calculator(/marine/bilge-pump-calculator) before you buy. I have spent more weekends than I care to admit elbow-deep in a 24-foot center console's bilge, and the lesson that stuck was numeric: my "1,100 GPH" cartridge pump measured roughly 700 GPH at the transom outlet 3 feet up, and once I added a 14-foot hose run it crept lower still. A friend's failed 3/4-inch raw-water hose on a...
What Size Windshield Wipers Do I Need? 2026 Size Chart by Vehicle
What Size Windshield Wipers Do I Need? 2026 Size Chart by Vehicle Most cars need a longer driver-side blade between 24 and 28 inches and a shorter passenger-side blade between 16 and 20 inches, because the two arms pivot from different points and clear different arcs of the windshield. Trucks more often run two equal blades around 22 inches, and many SUVs add a 12-14 inch rear wiper. Look up your exact sizes by make and model with the Windshield Wiper Size Calculator(/auto/windshield-wiper-size-calculator) before you buy a mismatched pair. A common mistake looks like this: "I bought 26-inch blades for both sides and the passenger one slaps the driver one halfway through the sweep." That happens because the two arms are almost never the same length. A typical mid-size sedan pairs a 26-inch driver blade with an 18-inch passenger blade — an 8-inch difference. Buy two 26s and the blades...
Outdoor Sports Calculator Data 2026: Archery, Avalanche Risk, and Hiking Pace in Real Sessions
Outdoor Sports Calculator Data 2026: Archery, Avalanche Risk, and Hiking Pace in Real Sessions Two real outdoor sessions on 2026-04-22 show how backcountry athletes actually use safety calculators: a skier ran five avalanche-risk computes in under a minute, watching the risk level drop from "Considerable 42%" to "Moderate 26%" as they varied recent snowfall from 12 inches to 0; and a hiker computed an 8-mile route with a 20-pound pack and got 265 minutes (4 hours 25 minutes) at a moderate-fitness pace of 1.8 mph. These are not recreational numbers. They are life-safety and trip-planning calculations, and the iteration patterns show exactly what backcountry users are negotiating: how much risk is too much, and how long will this actually take? This analysis covers five outdoor sports calculators over the 30-day window ending 2026-04-22: archery-sight-mark-calculator, bow-draw-weight-calculator, hiking-pace-calculator, avalanche-risk-calculator, and knot-strength-calculator. Use our Avalanche Risk Calculator(/tools/avalanche-risk-calculator) or Hiking Pace Calculator(/health/hiking-pace-calculator) for your...
