One of YouTube's most popular motoring experts has given drivers some advice that can help them find the best tyres for their car.

Scotty Kilmer has been a mechanic for more than 55 years and has gained a following on YouTube for his videos in which he shares tips that can help motorists save money and avoid causing expensive damage.

In one of his most recent videos, Scotty suggests that drivers should pay attention to a small code found on tyres which can tell how well they perform under certain driving conditions.

He explained: "Tyres have various ratings depending on how fast you want to drive. For example, if you have a car that goes more than 186mph, you have to buy ZR-rated tyres.

"Now, these Michelins are R rated tyres, they can go up to 106mph. We're old, we don't drive that fast, so it's perfectly fine."

All tyres sold in the UK feature a speed rating, ranging from A1 to Y, which signifies a legally approved limit that must not be exceeded.

Typically, most tyres fitted to standard cars in the UK feature an S or T rating, which allows for a top speed of 112 and 118mph respectively.

Drivers who exceed these speed limits run the risk of losing control of the vehicle and overheating the tyres, which may cause a blow-out.

Scotty also recommended that motorists who travel longer distances invest more money into their next set of tyres, with premium brands typically lasting longer than budget alternatives.

He advised: "Now, granted some tyres are just expensive. My grandson bought two front tyres for his Toyota Tundra. They cost $800 (£630), for just two of them!

"So, if you're cheap like me and don't drive all that much, just buy the third cheapest tyre you can get and put them on your car. They'll probably dry rot (crack) before you can use all the tread on them anyway."
