Understanding Tyre Load Ratings When Towing or Increasing GVM
If you’re towing a big caravan or you’ve increased your vehicle’s GVM, there’s one thing you really don’t want to overlook, your tyres.
Every tyre has a load rating, which tells you how much weight it’s designed to safely carry. You’ll find this number on the sidewall of the tyre. For example, on a Bridgestone Dueler 697 tyre with a 116 load rating, it’s rated to carry up to 1,250kg per tyre, under the conditions specified by the manufacturer.
However, ya gotta remember, the more weight you’re carrying, the more important your tyre pressures become. Heavier loads generally require higher tyre pressures to properly support the weight, control heat build-up and maintain good handling. Always follow the vehicle and tyre manufacturer’s recommendations for the appropriate pressure.
The Bridgestone Dueler 697 is a great example of a tyre built with these sorts of demands in mind. It’s tougher compound is designed to deliver increased durability and wear resistance, making it a far tougher option than many standard OEM tyres for drivers who spend plenty of time towing, touring and carrying heavy loads.
Before you head off, check your tyre ratings and pressures and make sure they’re up to the job. Your tyres are carrying everything you’ve got, so it pays to get them right.
