Can someone please throw some light on this issue of the heat and how it effects tyres out here please ?

I have a Toyota Vigo hi-lux , had it 3 years now and never changed the tyres. i rotated them periodically. Loads of tread on them, they are the same as the original brand supplied on the vehicle, Bridgestone duellist if I remember. The vehicle has covered 125k km.

I dont see any reason to change the tyres but I have read somewhere about how the heat in thailand can make tyres hard ? and even though the tread is fine they may not be safe because of this, has anyone heard this or know about this ?

Please enlighten me, should they be changed or not ?

Thanks for any advice.

No, 35 degrees outside is most likely much lower than the heat they generate through normal driving

Inspect the tires for little hairline cracks in the rubber... if you see them, it's probably time for some fresh rubber.

Most tyres in Thailand will last many years but a good idea to keep them out of direct sunlight as much as possible.

The silicon tyre shine applied to side walls regularly will keep them in good condition.

Along as your side walls are still smooth and as said already there is no cracking, there OK IMO.

My Vigo tyres same as yours, were worn out by 3 years, bald in places, surprised your tyres have done that amount of Km.

The vehicles has covered the Km's, the tyres are a mystery I doubt they are the original tyres although they are original brand supplied.

I bought the car some 3 years ago with 60k on it and the tyres at that time did look like new, assuming they were a recent change would mean currently around 70k which is good going I think.

i happen to work in the hottest area of western Australia and believe me it gets f#*king hot, the tyres we use are the same as the tyres over here, they are black, rubbery and roundish, the brand does not really matter for everyday usage.

unless the car sits at rest for long periods and i am talking like a year not a month, there should be no problem with them, as long as you

' rotate " them to even out the wear pattern the tyres will be fine until the tread wear out.

i recently bought a car from a friend here in LOS and he originally tried to trade it in on a new chevy, the dealer told him that " the tyres are expired" , this is a straight out con.

my basis for these wild assumption is that i grew up in new/second hand car yards, my father was a car and later on a truck dealer in Australia for over 40 years, i have heard every con in the book regarding cars.

so don't panic about your tyres just drive and enjoy.

Heat is not necessarily the enemy, but UV light is. It causes hardening and cracking. Modern tyres of decent quality seem more resilient to it than cheaper or older ones.

Keep your pressures correct and check the sidewalls (inner and outer) for cracking every once in a while.

Bridgestone are a good brand. I have Duellers (????) on my pick-up.

Tyres here are made of a far harder rubber than back in UK, my Pajero ran for over 110000 kms on the original set, they had to be replaced as they had started to fall apart, stll over 5mm tread but the carcass failed and went oval, all Michelin, have now fitted Bridgestones as were 5000 each rather than 8300 for the michelins, I would rather they wear out, sooner than failing.
