[山民進城] 換輪胎與車輪定位 (1)

(2013-06-22 06:19:42) 下一個
前幾天到 NTB 去換機油,看到  Michelin 有 manufacturer rebate。正好另一台車輪胎兩個輪胎已經磨到了林肯的頭頂,該換了。另外兩個也磨到了華盛頓的頭頂,也可以換了。

Place a penny into several tread grooves across the tire. If part of Lincoln's head is always covered by the tread, you have more than 2/32" of tread depth remaining.

Place a quarter into several tread grooves across the tire. If part of Washington's head is always covered by the tread, you have more than 4/32" of tread depth remaining.

磨得厲害的兩個是領導平行停車上了馬路牙子刮了一個,先換了。輪胎要一次換一對,當時花了700 多大洋。這回想幹脆4個一起換。問NTB OEM 輪胎的價錢,說是 4 x 250 = $1000, 包上胎(mounting),平圈(balancing), 但不包車輪定位(4-wheel alignment)。這個價錢在意料之中。因為前不久敵樂給過價:四個輪胎 $1350 + alignment $179。

等換油的時候,俺掏出聰明手機,上網查了一下找到一個最低價,總共便宜 200 大洋左右。以前俺在這個店換過輪胎,刹車等,花過好幾千大洋,是常客。跟店長商量,店長說:行,我給你這個價。於是第二天下班後把輪胎換了。不過,沒有時間做 wheel alignment。太晚了,他們要下班。換輪胎的時候,俺注意到後車輪不是想象中的 |----|  位置,而是像下圖右邊一樣。當時很納悶。於是引出另外一段故事。(待續)

Tire tips:

(1) Tire markings



(2) When were my new tires manufactured?

Since 2000, the week and year the tire was produced has been provided by the last four digits of the Tire Identification Number with the 2 digits being used to identify the week immediately preceding the 2 digits used to identify the year.

Example of a tire manufactured since 2000 with the current Tire Identification Number format:


In the example above:
DOT U2LL LMLR 5107
 
51 Manufactured during the 51st week of the year
07 Manufactured during 2007

太行兄好。車是比較常見的德國車。
巍巍太行 回複 悄悄話 山兄,你的車是CADILLAC或FERRARI?
湘西山民 回複 悄悄話 回複頤和園的評論:
周末好。俺這地方離Costco 遠不方便。700多是換兩個胎加4-wheel alignment 等等。輪胎是 Michelin energy plus MXV4 P235/65R17.
頤和園 回複 悄悄話 山民兄為啥不去Costco換輪胎?那裏也經常打折,還不是REBATE,而是直接就打。並且輪胎終身REBALANCE(記得是5千邁一次)。弱弱地問一句,啥車的輪胎700美元一個?俺也曾在馬路牙子上刮破一個新輪胎,在COSTCO換個新的,不到400美元。

Hawk兄周末好。回首壇理性不足鬥爭性有餘,讓人望而生畏啊。
tHawk 回複 悄悄話 山民兄很少出現幾曾回首了, 以為與同期"失蹤"的 Juskasked 妹妹私奔了.
