The Cost of "Close Enough" Tire Pressure

In the RV world, being off by just 10 PSI isn't just a safety risk—it's a financial leak. When your tires are under-inflated, the rolling resistance increases significantly. Your engine has to work harder to push that heavy rig against the pavement, guzzling extra diesel or gas every mile. According to the U.S. Department of Energy, for every 1 PSI drop in all four tires, you lose roughly 0.2% in fuel economy.

For a Class A Motorhome traveling 10,000 miles a year, that "small" pressure drop can translate into hundreds of dollars wasted at the pump. Grundig TPMS ensures you stay at the manufacturer's recommended Optimal PSI, every single mile.

Tire Longevity: Stop Burning Rubber

RV tires are a major investment, often costing $400 to $800 per tire for high-end Michelin or Goodyear models. Under-inflation causes "shoulder wear," while over-inflation causes "center wear." Both drastically shorten the lifespan of your tires. By maintaining precise pressure with the Grundig S04 or RV01, you can extend your tire life by up to 25%, delaying that $3,000 replacement bill by several seasons.

Avoid the $1,500 Roadside Nightmare

Ask any seasoned RVer: a roadside tire change on an interstate is expensive. Between the emergency dispatch fee, the premium price for a "mobile" tire, and the potential damage to your RV's chassis, a single blowout can easily cost $1,500 to $2,500. A Grundig TPMS is like an insurance policy that actually works to prevent the claim from ever happening.
