Tyres!!!
I know SBS Transit:
Bridgestone (everything except B10BLE CNGs and B9TLs) --> unsure about 1688K, 2888T.
Michelin (at least B10BLE CNGs and B9TLs) -

Yokohama got or not? -
SMRT ones are mostly Michelin, some special ones uses Bridgestone.

Sorry SBS Transit uses only Bridgestone, the Michelins are original tyres by Volvo, Volvo uses MichelinsOriginally posted by Donavan:Tyres!!!

SMRT ha, dunno who they contract their tyres to now, GT Radial was the previous one, and is the most common. Now should be Yokohama, but there are still more GT Radials now -
New Scanias also uses Michelins.Originally posted by Scania:Sorry SBS Transit uses only Bridgestone, the Michelins are original tyres by Volvo, Volvo uses Michelins

SMRT tires now should be TOYO, dunno what brand... saw it on a few habits.Originally posted by Scania:Sorry SBS Transit uses only Bridgestone, the Michelins are original tyres by Volvo, Volvo uses Michelins

TOYO good quality anot?Originally posted by XiaoTaro:SMRT tires now should be TOYO, dunno what brand... saw it on a few habits.
Seldom see cars use TOYO tyres leh. -
I think no good, but cheapOriginally posted by Scania N113CRB luver:TOYO good quality anot? Seldom see cars use TOYO tyres leh.

u mean they use car tyres? no rite?Originally posted by Scania N113CRB luver:TOYO good quality anot? Seldom see cars use TOYO tyres leh. -
the best is michelin
second is bridgestone
and third is Yokohama
Michelin tyres are a bit expensive but it's very good. SBST mostly uses new tyres on the front and re threaded tyres on the back -
The old Merc 911 3-tonners used Toyo tyres.Originally posted by Scania N113CRB luver:TOYO good quality anot? Seldom see cars use TOYO tyres leh. -
WHy is it so? Buses are rear-wheel drives. Shouldn't the rear tyres wear out more than the front ones? Why use rethreads on the rear? Is it safe?Originally posted by XTransbus:the best is michelin

Rear have 2 tyres on each side while front only 1. Superbuses have 3 rear tyres on each side. So the stress is more on the front instead of the rear.Originally posted by iveco:WHy is it so?

No. What i meant is that if car tyres also low quality, bus tyres also low quality mah.Originally posted by SBS9828X:u mean they use car tyres? no rite? -
Actually I was thinking more in the line of the fact that the front axle is used to steer and should hence be given better grip. Maybe.Originally posted by samtlk:Rear have 2 tyres on each side while front only 1. Superbuses have 3 rear tyres on each side. So the stress is more on the front instead of the rear. -
All only replying on the brand used, and none on the size.
Ok, from my old old records, the Mercedes 405 was formerly using 295 / 80R22.5 tyres, but later switched to 275 / R70 22.5 tyres, maybe to make their ground to 1st step height lower?
Other than that, the Alexandra Strider with Volvo B10M Mk 4 is also using 295 / R80 22.5, as with the DM3500, all double decks.
As for SMRT buses, the Mecedes 405 and 405G (box bendy) are using 275/R70 22.5 tyres, for the rest, sorry, lapsed in noting the information.
As for finding out what the numbers means, please google it.

No. Rethreaded tyres, sometimes when produced in large amount are of low quality. These low quality tyres tend to 'break' after sometime. If youre in malaysia, you see a bus using a rethreaded tyre on his front axel is a bad sign. If the rethreaded tyres 'break' when moving at high speed and if it's at the front, the driver would totally unable to steer his vehicle. Hence, it's safer for the driver to use brand new tyres for the front. If you put at the back, the danger is not much, because if one tyre break, the inner tyre will back it up. If the tyres break, the driver can still control his vehicle. 'broken' tyre bits can be dangerous especially on the expressway where those bits can fly and can dent a car body or break their windshield.Originally posted by SBS3625D:Actually I was thinking more in the line of the fact that the front axle is used to steer and should hence be given better grip.

But then why do you say Michelin is better than Bridgestone? Any proof to back it up?Originally posted by XTransbus:the best is michelin

i have several several friends who drive trucks in europe. The tyres should be the same. He said many prefer michelin due to their 'quiteness'. Some tyres 'roar' when moving at certain speeds.Originally posted by Donavan:But then why do you say Michelin is better than Bridgestone? Any proof to back it up? -
What you do you mean break? Tyre blowout? The tyre explode?Originally posted by XTransbus:No. Rethreaded tyres, sometimes when produced in large amount are of low quality.

Most SBST use Bridgestone R192

New tyres are usually used on the rear wheels then after the first rethread, it will be used on the front wheels.
Two rethreadings and after the third usage of a tyre, it would not be used. -
I see many discussions. Allow me to one shot clear the air.
New tyres are used in the front because of 2 main reasons. Steering & braking. When steering, the tyres are subjected to high shearing force, therefore it is impt to keep the best tyres for that. Also, when braking, all forces are thrown to the front. That's why most load is absorbed by the front suspensions and the remaining load on the tyres. We call them 70% front 30% rear.
Rethreaded tyres however are also quite good in quality. Even if they are to be used in front it will also be OK. The front tyre's lifespan and condition apart from the braking & steering capabilities of the bus, it also depend on the king pin condition. If the kingpin is slack, the wheel tend to rattle or toe in/out and causes uneven wear. So that's why you can see part of the tyre wear badly yet the other part is OK.
Comparing between michelins and Bridgestones, in SBS bus applications, the maximum speed is only 60kph. Even with severe load, the bus can only generate so much load. So grip is quite ample for any of the bus tyres found in the market today.
However, I personally support only 3 brands of tyres Pirelli, Metzeler(only produces motorcycle tyres) & michelin. Because when I play track, I am jamming brakes sometimes at speeds of 250kph. So apart from the Bitubo & Ohlins suspensions which I used before supports my demand, the tyres are also equally impt. And Only these 3 brands give me that type of confidence. I never recommend Bridgestone & dunlops for high performance uses.
