Why used tyres are a bad idea

Lesotho Times - - Motoring -

WHEN money is tight, you might be tempted to buy used tyres in­stead of new ones. They can be much cheaper and might even look prac­ti­cally new.

It’s tempt­ing to go that route and giv­ing a used tyre a new lease on life even seems eco-friendly. Con­sumers are try­ing to pinch pen­nies any­where they can nowa­days, and buy­ing new re­place­ment tyres can be un­ex­pected and costly. Steeper and more fre­quent tyre price hikes, re­flect­ing the higher cost of petroleum-based raw ma­te­ri­als, will only add to the pur­chase pain. Some con­sumers might opt to look for a cheaper al­ter­na­tive by buy­ing par­tially worn used tyres. Is this a good way to save money?

But we rec­om­mend against it. Af­ter all, you don’t re­ally know the history of that used rub­ber. And be­cause tyres af­fect your car’s safety, we don’t think it’s worth the risk to save a few bucks. What could go wrong? Here are some con­cerns. Mis­use. If a tyre was driven while it was un­der­in­flated or over­loaded, which is very com­mon, it may have sus­tained in­ter­nal dam­age that’s not vis­i­ble to the naked eye.

De­fects that aren’t ob­vi­ous. Most con­sumers prob­a­bly aren’t skilled enough to de­tect prob­lems that a tyre ex­pert would spot im­me­di­ately, such as a torn mount­ing bead, prob­a­bly caused by re­mov­ing the tyre from the wheel, or bad­lydly ex­e­cuted re­pairs.

In spite of the fact that sec­ond­hand nd tyres may look ok okay, they could d be five or moree years old. Un­li­kee fine wine, tyress don’t im­prove e with age. In­stead, , they be­come wornn and sus­cep­ti­ble e to mal­func­tionn or punc­ture. Youu usu­ally can’t tell ll how much a tyree has aged just byy look­ing at it. Whilee a tyre might look fine on the out­side, the rub­ber com­pounds in­side may ox­i­dize, caus­ing the tyre to de­te­ri­o­rate from the in­side out. In some cases, used-tyre deale deal­ers paint their prod prod­ucts black in or­der to make them loo look new.

Un­like with the sa sale of new tyres, th there’s lit­tle qualit ity con­trol in the used-tyre in­dus­try. Used tyres may come from scrap heaps or salv vage yards. They may not even get a safety in­specti tion be­fore they’re so sold again. It’s al also im­por­tant to note that used tyres are not sub­ject to fed­eral stan­dards. This means that hav­ing such tyres in­stalled on your ve­hi­cle goes against RMA- and au­to­mo­bile-man­u­fac­turer-ap­proved prac­tices for the re­pair and re­place­ment of tyres. These stan­dards were es­tab­lished so that peo­ple can use public roads safely. Un­known ef­fects of ag­ing. Tyre com­pounds de­grade over time. Some au­tomak­ers rec­om­mend against in­stalling tyres that are 6 years or older. And some tyre mak­ers rec­om­mend re­plac­ing any tyre that’s 10 years or older. Be­cause you can’t see how ag­ing weak­ens the tyre’s in­ter­nal struc­ture, an older tyre, whether or not it has been used, shouldn’t be trusted.

Some used tyres for sale at the less honourable used tyre shops can be prac­ti­cally worn out with prior patch­ing, bub­bles or thin spots. Some of these tyres are al­most like seives. –– Prac­ti­cal­mo­tor­ing
