Tires for High-Performance SUVs – Finding the Best Fit

05/11/2020

  • Powerful SUVs need tires with special properties
  • On-road or off-road – where will you be driving your SUV?
  • M+S symbol does not mean a tire is suitable for wintry conditions

Tires for powerful SUVs and 4WD models have to master more challenges than their counterparts for “normal” cars. “When we compare the vehicle data, we see that the big, fast models ask more of their tires,” explains Continental tire development engineer Andreas Schlenke. “In terms of weight alone, an SUV tips the scales at one third heavier than a normal car, so the tires need a higher load capacity. These are XL tires (XL = Extra Load), a load range developed to offer higher load capacity than standard, not least with SUVs in mind. Then we have to allow for the vehicle’s higher center of gravity, longer suspension travel and a greater track width than in smaller cars. So when we’re developing these tires, we need to invest more time and effort to ensure safe braking and precision handling. After all, in the more powerful SUVs we’re talking about top speeds not far below those of high-end sports cars.”

According to Schlenke, “it’s a bit of luck for developers” that only a small proportion of SUVs and 4WD models are actually driven off-road. Just delivering the safety-relevant properties, low rolling resistance and good ride quality is challenging enough. “On top of that, off-road driving calls for a chunkier tread pattern with good self-cleaning properties, plus cut-and-chip protection and strongly reinforced sidewalls,” he says, describing the tires. This type of construction is less than ideal for fast highway driving because, out on the road, the chunky lugs that interlock with scree and stones on rough terrain cannot put down enough grip to handle fast cornering and braking from speed. “That’s why real off-road tires bear the M+S symbol,” says Schlenke. “That’s the hallmark of a specialist – after all, M+S stands for mud and slush.” So before buying tires, owners of SUVs and 4WD models should think carefully about where they are going to be driving their vehicles and choose their tires accordingly.

Schlenke also warns against winter driving on chunky M+S tires that do not bear the three-peak mountain snowflake symbol: “Four-wheel drive tends to suggest strong grip when moving off on wintry roads,” he says, “but with off-road tires that deliver inadequate braking distances and poor lateral guidance on snow and ice, you will only put yourself and other road users at risk.”
