I wrote an article about this here sometime ago.

Basically higher inch the higher profit margin it is. This is also a way to support the cheap low inch prices 😜. Same analogy like business class tickets supporting cheap economy ticket price.

Thanks, Doc!

Is yokohama tire good for malaysian road?

wonder what is the rim spec for the 2022 bezza 15" ?

Coming from Primacy 4, after using them for 3 years; previously was on PS4 which only lasted me 2 years - I'm deciding between the Michelin Primacy 4ST, Continental UC7, Continental MC6 and the Kumho HS52.

The PS5 is very tempting, with the steering feel, ZR rated (I do a lot of 200kmh driving) and overall performance. What's turning me off is the road noise, rolling resistance and the relatively short longevity, not really useful when I do KL JB commutes majority of the time. I don't skimp on tires, but I value safety, quietness and longevity these days. Which one should I go for? 215/55/17 btw

Try Yokohama Advan Apex V601.

It is a UHP tire with low noise. Not sure about longevity

tahu treadwear spec ?

gotta use back primacy 4 st becos others lifespan cannot fight him

I got salesman friend using Continental UC6 drove over 80k still not reaching the wear indicator yet, he told me if not because he got family or baby to fetch the tires he felt can easily reach 100k. He travel a lot from Ipoh to Kelantan to do sales, so even with a lot of hill roads driving the tire still can take the abuse. BTW he really take good care of his ride, every 6~7k sure will go service, rotate & alignment thus why his tires can last long.

280 if I'm not mistaken

That's even lower than the PS4S, unlike to consider that

What car tho?

Just a friendly reminder that the UTQG isnt comparible between brands ya. 280 treadwear on a Michelin doesn't mean that it will wear out similar to a 280 on a Goodyear/Conti/Hankook etc.

FYI, my salesman friend ride is Subaru Xv STI version 2015. Fitted with 225/55R17 Continental UC6 previously (now latest if not mistaken is MC6).
Most people think AWD rides will make the tires wear faster, but in reality not. If you drive moderately and always rotate and check your alignment settings it can last long as normal FWD cars also.

The UTQG is tested in lab & act as reference for buyers, in reality it depends on how the owner drive it.
Even with the same tire brand with different driver also can come out different results. Just imagine both same size Michelin Primacy 4 tires, 1 always layan corners at high speed & pick up like drag race from traffic lights, while another driver drive normally.. who will think it will last long? Simple logic.

UTQG is a self certification type. This means that any manufacturer can declare whatever value they want as long as the TIRES WITHIN IT BRAND performs in line with what they have defined on a standard test track (example provided below). UTQG grading is govern by the US Department of Transport.

Example;
Let say tire manufacturer A has 4 tire lines name J, K, L & M and that, each is assigned a UTQG treadwear value of 100 200 300 and 400. As long as the results from the manufacturers' testing show thats M last 4 times longer than J (since M has 400, J is 100), L last 3 times longer than J, and K last 2 times longer than J, they grading is considered correct. All Manufacturer A has to do is to show the test results if the Department of Transport asks. Lets say tire line J achieves 40,000km in the treadwear test.

If Manufacturer B comes and does the same (and have the same rating for their tires J K L and M as A), but for thier tire J their results they got 20,000km. Their rating of 100, 200, 300 and 400 is still valid. Because between the tires within their brand their relative performance is reflective of their grade.

So in other words, you cannot compare the values of a treadwear rating between manufacturers.


Your comment about how the car is driven is still correct and will effect how long the tires will last.

Edit: just to make it clear, from the example: Manufacturer A's tire J has 100 Treadwear rating and lasts 40,000km on a standard test track, but it will perform similar to Manufacturer's B's Tire K that has 200 treadwear rating. All this because there is no standard reference in the UTQG treadwear rating, only relative performance within the respective tire manufacturer. Hence why its meaningless to compare treadwear rating between manufacturers.

Do extra load sidewalls make the ride less comfortable?

hi, how's the aquaplaning & wet grip? if compare with PS4

Primacy 4 is kinda slippery in wet, compared to my PS4, i think even my Goodyear Excellence

Looking to change my wife's car tyres..4 pieces..she drives a Honda City..15'..

What are the options that I have around PJ area and what brands..

Based on the price table here

Viking CityTech CT6 185/60R15 191
Toyo Nano Energy NE03 185/60R15 198
Dunlop SP Sport J6 185/60R15 209
Continental ComfortContact 6 CC6 185/60R15 236
Continental UC6 185/60R15 (UC6) 245
Michelin Energy XM2+ 185/60R15 245
Goodyear Assurance TripleMax 2 185/60R15 247

What are you main requirements?

Michelin XM2+ is the best choice with great balance between wet braking & mileage.
