通常一問到呔, 好多時都會圍住個幾個問題, 了解多啲
深紋都唔代表住仲可以用. 因為膠會老化, 咬地力大減, 特別係濕地上. 不能只睇紋去判斷是否仲可以用.
2. 幾時會老化? 可以頂到幾耐?
"唔知" 其實真係一個答案黎的.
3. 輪胎有冇保養
1. Tyre depth looks like it is still usable
2. How long will the tyre age?
"No idea" is actually a correct answer
3. Tyre Warranty
2. 幾時會老化? 可以頂到幾耐?
2年? 3年? 5年?
以5年時間為指標 [Source: Michelin website]
但差不多所有輪胎製造商都會講. "It varies" (視情況而定)

無法得知一條呔可以實際用到幾耐 [Source: Michelin website]

"唔知" 其實真係一個答案黎的.
3. 輪胎有冇保養
現時行貨保養有
Kenda (建大) - 12個月保養.
輪胎呔壁等位置(因質量問題)凸起 ("即生仔"), 可以更換全新輪胎. (需要檢察是否因質量問題). 中釘漏氣等問題不受呢個保養入面.
Dunlop - 12個月保養
冇詳細了解, 車主需要另外問問佢地.
Continental (馬牌) - 180日保養.
180日內 或 (唔記得左幾多里) 內, 若出現 "生仔"等質量問題, 可以更換全新輪胎.
"另外若中釘都可以受保" <- 呢個唔知仲有冇, 車主要自己另外再問.
Goodyear - 90日保養
90日內 或 (唔記得左幾多里) 內, 若出現 "生仔"等質量問題, 可以更換全新輪胎.
其他牌子就冇特別提及到有關保養問題, 但其實您裝左冇幾耐就 "生仔" 既話, 就需要拆條呔出黎俾佢地檢查, 發現係質量問題就會賠番條呔俾您.
不過以上所有保養既共同點係... 裝拆費用係另計的. 費用就要車主自己問番賣俾您既輪胎店.
4. 呔生仔補唔補到
因為係輪胎入面既鋼線斷裂, 特別係打氣個陣先會見到出現"生仔", 特別係呔肚位. 所以係補唔到.
但車主可唔可以, 唔好見到 "生仔" 個位就用腳踩落去睇下有冇問題呢?
至少都唔好係我面前踩. 我唔想睇住個位突然俾您整爆, 整傷您隻腳.
您未見過佢點爆, 睇左相, 仲有video 您就知點解我唔想您地咁做.
5a. 呔肚位有破損或受損(冇漏氣), 補唔補到
呢個應該係最多人問既問題. 未答補唔補到之前, 先講講一樣野.
依照交通條例說明 (暫時係我寫呢個post 都仲係, 之後仲係唔係都可以睇番運輸署), 任何車輛的輪胎都不能有切割口超過25毫米的長度.
但冇提及如果"補" 個個位, 仲算唔算係都仲係叫"切割口". 驗車都係. 因為驗車都係跟番交通條例.
咁至於呢個位係咪可以 "補".... 您俾得起錢, 係真係得既. 但大前提係要拆條呔出黎. 仲可能要超過一日既時間. 搞搞埋埋, 個費用仲可能貴過您買一條新呔.
如果您出現呢個情況, 不如唔好理佢吧. 睇完呢個post都唔好問我真係補要幾錢, 因為我唔補呢啲.
5b. 呔肚位爆呔漏氣
之前有提及到補呔唔係間間都補到, 並提及到內補既問題.
經過多次實驗後, 決定delete 左之前個post 係呢個從新寫過.
內補並不是萬能. 特別係呔肚位. 補到咪繼續玩多陣, 但基本上您都要預左買番條新呔.

基本上所有 輪胎製造商都會講, 如果您條呔係呔肚位中釘漏氣, 都不能修補並需要更換.
如果您經Tyrehood online 方式購買, 記得下載番 Tyrehood Zone 手機apps, 再whatsapp 番俾Jimmy 知, 我會update 番您個account, 先可以用到apps 入面既所有功能.

Most of the questions are related to the following, it will be good to know more about it.
Some may still talk about it. The depth of the tyre that looks still usable does not mean it really keeps your car running as the rubber will age, thus causing a drop in traction performance, especially during wet condition.
2. How long will the tyre age?
Two years? Three years? Five years?
[Source: Michelin website]
But most of the manufacturers will say, "It varies"

"Estimating the duration of a set of tyres is a much more complex affair" [Source: Pirelli website]
"No idea" is actually a correct answer
3. Tyre Warranty
Authorized Official Tyre has warranty, for the following brands:
Kenda - 12 months warranty
Tyre sidewall or other areas has a bulb or ball shape due to tyre quality issue. (require further checking if it is because of quality issue). Sole agent will deliver a new one for you. (Tyre puncture is not included in this warranty)
Dunlop - 12 months warranty
I did not check in detail. You got to ask them.
Continental - 180 days warranty
Within 180 days or a certain mileage, if the tire has a bulb due to quality issue, sole agent will deliver a new one for you.
"tire puncture is also included in the warranty" -> I am unsure if this term is still valid. You got to ask them.
Goodyear - 180 days warranty
Within 180 days or a certain mileage, if the tire has a bulb due to quality issue, sole agent will deliver a new one for you.
For other brands, there is no specific warranty being mentioned. However, you could request for checking the quality issue, especially if the tire has a bulb after you just installed. The cumbersome point is the tire is needed to deliver to their office for checking. If quality issue is found, they will deliver a new one for you.
Anyway, the sole agents will not pay for the "labor fee". You need to ask the retail store if there is any "labor fee" incurred for replacing and/or deliver to the sole agent for checking
4. Can it be fixed if the tire has a bulb
It is unable to fix the bulb as it is caused by broken lining in the inner tyre.
Anyway, could you avoid kicking the bulb?
At least, not in front of me. I do not want to witness the bulb suddenly burst and injure yourself.
If you have not seen how the bulb will burst, I can share some photos and videos.
5a. Tyre sidewall damaged (no air leaks), can it be fixed?
Most has raised up this question if this part can be fixed. But before that, something needs to be taken note that,
According to the Hong Kong Road Traffic Regulation, tire that has a cut exceed at least 25mm should not be mounted on any vehicle. (subject to changes if the ordinance is amended)
But it does not mention whether it is still consider legal if the cut is "repaired". The same rule applies to vehicle inspection.
If you can fork out money, it can be "repaired". But the tire needs to be dismounted, and it may take longer than a day to "repair". The cost may even be higher than purchasing a new tyre.
Either you ignore it, or you purchase a new tyre. Do not ask me the cost of patching it up as I do not have such service.
5b. Sidewall has a puncture
I mentioned about internal patch previously. After experimenting, I decide to delete that post and write a new one about this.
Internal patch is not a sure-fix way to patch the sidewall puncture. If it stops leaking, you could still use it but purchase a new one should be the only option that you have in mind.
[Source: Michelin website]
Basically all the tire manufacturer will tell you to purchase a new one if the sidewall is damaged.
If you have purchased at Tyrehood online, remember to install the latest Tyrehood Zone app and create a account, and let me (Jimmy) know about it. I will update your account such that you can access Tyrehood customer only functions.
