philthebook Posted June 12, 2020 Share Posted June 12, 2020 GF has been told that we should change the tyres on her car at it's 40,000km service (Toyota Yaris 3 years old) In the uk we only change tyres when the tread is low, do they do things different here (TiT) due to the poor roads and the heat? 2 Link to comment Share on other sites More sharing options...
Popular Post transam Posted June 12, 2020 Popular Post Share Posted June 12, 2020 Forget it, sales talk.....T Tyres are "OK" guarantee wise for 6 years on the car (Michelin etc)... Toyota's own PDF file for a pickup states, tyres at six years old should be inspected by a professional.... 6 Link to comment Share on other sites More sharing options...
jadee Posted June 12, 2020 Share Posted June 12, 2020 It's just their advice - take it or leave it. If you don't want to change, tell them no. The legal minimum depth tread is 1.6mm, but heat, humidity, and sunlight all shorten the lifespan of tires here compared with in the UK or other more temperate climates, unless you've kept the car in a garage.

No, you just change tires when they are worn out, not by K's Typical upsell nonsense. 2 2 Link to comment Share on other sites More sharing options...
Popular Post PFMills Posted June 12, 2020 Popular Post Share Posted June 12, 2020 That is up to you and opinions vary. But I will say that after three years the rubber will be harder and tyre performance will be reduced. This is particularly noticeable in hot countries. There is a lot on the internet regarding stopping distances on new and part worn tyres, especially performance in the wet. Say your car were to stop just ten feet later on older tyres compared to what would have happened on new ones, that could mean big damage to your car or even a life changing experience for some one. I am fully aware that tyres are guaranteed for more than three years, but not against maintaining as new performance. So you need to weigh up the risk against your bank balance. When you buy tyres, it is a good idea to look at the manufacturing date, they could easily be nine months old. They don't age much on the shelf, but someone will point out to you at three years they want changing when in fact they easily have another nine months. 2 1 1 Link to comment Share on other sites More sharing options...
Bruce Aussie Chiang Mai Posted June 12, 2020 Share Posted June 12, 2020 You got wear indicators in tread, I wear them down an extra 20%. Rotate them regularly and correct tyre pressures should get you min 60k. Honda said same us at 40k service I changed at 70k. ????❤???????? 2 Link to comment Share on other sites More sharing options...

Popular Post Denim Posted June 12, 2020 Popular Post Share Posted June 12, 2020 Tyres harden in the extreme heat here after a few years. Often have plenty of tread left and ok to use but the ride becomes a bit harsher and a bit noisier. 4 Link to comment Share on other sites More sharing options...
Lacessit Posted June 12, 2020 Share Posted June 12, 2020 I got 70,000 km out of a set of Michelins on my Vios. Were not even down to the tread wear indicators, mechanic said I had cracking in the treads. Probably had another 5000 - 10,000 km in them. 40,000 km is just sales talk, 50,000 should be a minimum unless most of the travel is on dirt roads.

Yes very true Trans, Michelin do give a guarantee, and yes tyres will last years but I have a different priority wrt tyres. All MICHELIN® tires4 (both replacement and original equipment) come with a limited warranty for treadwear, as well as a limited warranty which covers defects in workmanship and materials for the life of the original usable tread, or for 6 years from date of purchase, whichever occurs first.

alacrity Posted June 12, 2020 Share Posted June 12, 2020 3 year old car if purchased new, should have 3 year old tires fitted. That may stretch to 4 years, dependent on time of completion. Check the DOT code on each tire for date of manufacture (first 2 digits are week and second 2 digits are year). So the second digits should show; 17 or 18. If you're being told that you need to change all 4 tires. They're likely to be scamming you. Lots of reasons why they may be compromised though, especially front tires nowadays (but that would be 2 tires). Listen to what they're telling you. Read up on tire specs and look for yourself before deciding what to do. Tire brands and variants thereof are a personal preference. All meet the minimum of the approved standard. Tires with over-stated 'ECO' advantages give a hard ride which will get worse over time. Wife's daily rider came with Michelin ECO's and after 2 years had all the characteristics of a Flintstone wheel. They may save on fuel, but shake your car to bits. Typical of what's marketed as environmentally friendly. Link to comment Share on other sites More sharing options...

Often have plenty of tread left and ok to use but the ride becomes a bit harsher and a bit noisier. Braking distance is increased also. Most of my sedan tires are ready to be chaned by about 40K kms as well - they still have tread but get hard and noise increases also. I have a crv now, but most owners seem to change about about 70K on that car. Probably as the tread is deeper. 1 Link to comment Share on other sites More sharing options...

Popular Post HauptmannUK Posted June 13, 2020 Popular Post Share Posted June 13, 2020 Tyres deteriorate with age because UV light and the atmosphere cause oxidation and depolymerisation of the rubber. The rubber goes hard and starts to crack. The tread becomes less compliant and therefore grip is reduced. Carbon black in the tyre acts as a sacrificial absorber of the UV to protect the rubber. Over time it is progressively used up and the tyre becomes less black and more grey. That's why tyres left in the sun everyday tend to 'rot' more quickly. I wouldn't use a tyre beyond about 6 years here in Thailand. As a young engineer I had a colleague killed by an old tyre. He took a test car out on the track and a tyre broke up at high speed. The car flipped off the track. HSE investigated etc. It turned out that the tyre was 'new old stock' - manufactured over 10 years previously but somehow only just fitted to the car. Nobody had thought to look at the date code. 4 Link to comment Share on other sites More sharing options...

Even if they say new it may well have been sitting somewhere for 1, 2 ,3 years or longer... Very important. 3 Link to comment Share on other sites More sharing options...

Proper tire rotation for equal wear then change when the indicator on threads shows or 3mm threads. Link to comment Share on other sites More sharing options...
Popular Post soi3eddie Posted June 14, 2020 Popular Post Share Posted June 14, 2020 I would change after the tyres are 3 years old regardless. After that time in the heat and on the road at 40,000K you've had good value and the safety vs replacement cost curve increases dramatically. All it takes is a downpour with low tread and hardened rubber and it's possible to be sliding and spinning everywhere. Personally I'm more concerned about other vehicles running on slicks but you need to have confidence in your own vehicle's safety. 4 Link to comment Share on other sites More sharing options...

Although they seem to be a big one-off cost, and the 18" or 20" tyres on our Fortuner won't be cheap, if you calculate the cost per week or month they are a bargain, and what price do you put on safety, Edited June 14, 2020 by Tuvoc typo 1 Link to comment Share on other sites More sharing options...

Dazinoz Posted June 14, 2020 Share Posted June 14, 2020 I used to Novated lease cars through work back in Oz. For tax purpose I had 4 years with 25,000k year. 1 lease the tyres (cant remember the brand) lasted the full 100,000k. I have a small car here and when I was told I needed to replace tyres after 4 years and only 40,000k I questioned them. He then pointed out that even though plenty tread left the rubber was starting to perish and crack. Heat, poor roads, poor quality rubber who knows but I didn't want my car letting me down driving down a Thai highway, there's a enough to contend with as it is so I changed them. 2 Link to comment Share on other sites More sharing options...
ujayujay Posted June 14, 2020 Share Posted June 14, 2020 Still have the original Set of Dunlop Tyres on my 4yrs old Mazda 2. Now 60k and still in good Shape, no cracks. I changed after 3 Years the Wheels from rear to frontaxle, what reduced the noise remarkable. I think, I go up to 100k before I change. 1 Link to comment Share on other sites More sharing options...
Popular Post natway09 Posted June 14, 2020 Popular Post Share Posted June 14, 2020 If a car is parked in the sun all the time the rubber will go very hard & can be dangerous.

katatonic Posted June 14, 2020 Share Posted June 14, 2020 Tyres do age and the performance degrades dramatically. The ride and braking performance as well as cornering grip will reduce by a significant amount after 4-5 years. Regardless of the tread depth, do not use tyres here after they're 5 years old. Change them and the difference is dramatic. My wife's car, when we met - a Honda Jazz, had a really bad ride and terrible grip. Changed to Michelin Pilot Sport 3's and the difference in comfort & grip especially in the wet, was incredible. I have bought several sets since for different cars but always go for Michelin Pilot Sport - now PS 4. Buy tires from the company that's spending the most on research, which is generally Michelin. Never scrimp on the things that attach you to the road! And this is why Thais drive so slowly in the wet. They know how <deleted> their tyres are.. 2 Link to comment Share on other sites More sharing options...

At least in LOS they are reasonably priced. Where have you seen Thais drive slowly in the wet? Only time I see Thais driving slowly are when they are looking for a food stand or restaurant in an unfamiliar neighbourhood. 2 Link to comment Share on other sites More sharing options...
