Inner Tyre Wall Cracking - MOT Failure

[anonymous-user]

I blame a lot of factors on tyre degradation.

I’d say car tyres aren’t made to last anymore mainly because the expectation is that you change them every few years or 10,000-20,000 miles, whereas say commercial vehicles like trucks cover vast mileages and can last up to 10 years.

Cars are much heavier than they used to be, tyres are wider and often lower profile. Lower profile tyres are easy to damage on poor road surfaces especially potholes. Speed cushions tend to wear the inner shoulders of the tyres and put a lot of strain on suspension components.

A lot of modern tyres are a really soft flexible compound, my new winter tyres are incredibly soft and compliant in the sidewalls, my super soft motorcycle tyres almost press onto the rim.

I'm afraid not. For example, the early-2000s Fiesta ST came on 205/40R17s

45 profile wasn't at all uncommon on "warm but not ridiculous" performance level cars of that period.

I'm not sure I would call a Fiesta ST a family hatchback but fair enough, maybe it's also my predisposition to run a slightly older car, but also if the average car age in the UK is 8years then back in 2002 a lot of people where still driving a mid 90s car.
