Passenger cars are getting heavier Light trucks (SUVs) are now being driven in lieu of compact station-wagons.

Vehicle classes are also getting larger and heavier. Subcompacts that used to weigh less than 1000kg are now about 1500kg and EV variants are over 2000kg!

So is over-inflation. Always inflate to the correct pressure as per the placard. If you are driving in unusual conditions,

My little Jimny weighs bugger-all but needs Light Truck tyres. On-road pressure is a very light 26 PSI. If I am driving through Sand, Mud or Snow I will deflate to an appropriate pressure and drive slowly. If I am driving over rocky terrain, I will also deflate to an appropriate pressure for better adhesion.

As soon as I hit the Tarmac again, I will reinflate back to 26. If I am carrying more weight or towing, I will inflate the rear tyres to 29.

The three biggest things that kill a tyre are;

• shitty roads
• aggressive driving
• heavy vehicles (like EVs and oversized SUVs)

That said, cheaper tyres are typically made of cheaper compounds that age poorly.
