All 4 tyres have this cracking, but only on the outside edge, worst tyre shown.    They are Bridgestone 195/50x15 tyres on a MX5, they don't lose air and seem fine on the road, even when “pushing” on a bit. What caused this and should I panic and hit the credit card for new tyres on a car that isn't used much? Thanks |

The delights of low annual mileage is the tyres will need replaced because of things like this sadly. I'm no expert, but i start to do more regular checks on tyres when the small cracks start, and will never get to the stage that these are at.
All the very best,
Geoff.

Yep look for a date code. beware of 2nd hand tyres that are very old but are either new old stock or have loads of tread on. I bought a few off ebay and one was 17 years old, so look for date codes.

Thanks, 02/12 is the date, so time for Christmas tyre shopping.
All I've got to do now is convince the girlfiend that she wants tyres for Christmas!

Tyres have a SHELF life of about 4 years. Tyre date stamps are very useful. The tyres on a new car can be older than four years if it's been sat around.

The tyres that failed the mot on my Sister's car weren't very old (the year 2012 sticks in my head), and they looked just like the tyres the OP posted.
The guy in the tyre shop said it was the composition of the tyres these days, as modern tyres are silicate based, which deteriorates quite quickly, especially with little use. He might have been talking rubbish to sell tyres, but it sounded plausible.

Advise only (unless its changed fairly recently), to fail there has to be cords showing in the cracks. Anyway, big smokey burnout until they pop then change them? |

The tyres on our garage track day mx5 are the same if not worse than those and it gets a proper pasting on track , unless you drive flat out for long periods I wouldn't be too concerned about those cracks causing any issues as the tyres aren't that old

Personally I'd be thinking of changing them for the sake of £200-£300 and your safety.

If they were mine, TBH I'd replace them. I scrapped some (otherwise good condition) part-worns that were similar to that, last week.
Re Welshpug's dismissal of the Toyos, they are not a bad tyre to be fair, they are cheap-ish and reasonable value but not the upper echelon. I used them on the hillclimb car for its first year in my championship and they were ok. At the start of the following season I changed to some part-worn Michelin Pilot Sport 3s that I got from a mate for a song, and the difference there was amazing :-) I'm now racing on Advan AD08Rs, but use the Toyos to go to-from in order not to ruin the Advans on the potholes sorry public road.
It sounds as if you aren't looking for the ultimate sporty tyres, so the Michelin Energy Savers would be a good "safe" buy, the Toyos are cheap and cheerful and not a BAD tyre.

Yep look for a date code. beware of 2nd hand tyres that are very old but are either new old stock or have loads of tread on. I bought a few off ebay and one was 17 years old, so look for date codes. For this reason I am always skeptical on buying part worns. I almost did for my M3 but two things made me think otherwise; -The front tyres on mine haven't worn right due to previous alignment issues with the car. I've previously bought tyres like this. That may be OK on a car used in town (questionable with people who love stepping out into the road while Tindering, Instragramming, Pokemon Go!ing but not checking the road) but on a quick car it can make it mega nervous On a few cars I've just changed the strangely worn tyres for new ones and transformed the handling of the car. I am surprised at that age. PandaSelecta may have a point but IMO it's probably down to a lack of heat buildup in the tyre which is also meant to do this as well as underinflation. The amount of good cars I have bought with low pressures all round once checked is surprising. The tyres on our garage track day mx5 are the same if not worse than those and it gets a proper pasting on track , unless you drive flat out for long periods I wouldn't be too concerned about those cracks causing any issues as the tyres aren't that old I wouldn't agree entirely with that after my experience but given the age I may be tempted to drive on those tyres the OP put up, but on the front if a FWD car. If they were mine, TBH I'd replace them. I scrapped some (otherwise good condition) part-worns that were similar to that, last week. Re Welshpug's dismissal of the Toyos, they are not a bad tyre to be fair, they are cheap-ish and reasonable value but not the upper echelon.

It sounds as if you aren't looking for the ultimate sporty tyres, so the Michelin Energy Savers would be a good "safe" buy, the Toyos are cheap and cheerful and not a BAD tyre. They're OK are T1-Rs but they can be a little unpredictable in the wet. For the money they are fine ; I'd have them over any Avon which is like a ditchfinder in comparison. I've preferred the Toyos over the Kumhos to be fair. |

ChasR,
I'm always wary of part-worns but the PS3s were from a reliable source so I was happy to take them. Otherwise you don't know if they have spent their lives smacking into kerbs, being repeatedly thrashed or what.
It's interesting looking at cars in the roadgoing class on rounds of my championship. Previously we were restricted to the MSA List 1A which is essentially "normal" road tyres, the most sporty tyres were the Michelins or older Advan AD08s (NOT the AD08R which is softer compound) and these were mostly what you would see. This year we went over to list 1B which is essentially road-legal competition tyres and includes the AD08R, and Toyo's R888 which is very popular.
The T1-R is OK (you are right that they are a bit more suspect in the wet) but has very thin sidewalls so they are quite sensitive to tyre pressure. On my road car (Skoda Fabia) I have Avon ZV5s and they aren't great (not really terrible, though). For normal road use I'd be happy going to T1-Rs next time round (if the car lasts that long!).

I guess tyres can be a very personal thing as different people like differing feedback. One person likes a snappier car, others want something softer and more forgiving  . I also found the T1-Rs were suspect to pressure. In my GTi-6 I had to overinflate them ; the sidewalls were too soft and the edges of the tyres wore alarmingly! My only gripe with them really is that they don't last. OK on a weekend car, but on a daily it can become expensive in the long run. With the Avons, it was more the wet weather experience. Now and again I will go with part worns but they will generally be from myself or as you say a source known to you, but many are meant to be sold illegally due to not being stamped Part-Worn The price some people want for them though can be surprising once you account for delivery or collection/time and fitting. I guess I love a bargain as much as anyone. As for people saying "You get Part Worns on a used car, so big deal" there is a quite a difference  . You get the test the car beforehand, and see how it pulls etc. If I wasn't so tight I'd have changed the fronts on my M3 as even the better worn rears being replaced has made the car far less nervous, but 2 tyres on the are the same as 4 good tyres on most cars out there... Stupid I know. That and on a few cars I've had lethal tyres. Below is one example of that, but in hindsight I should have just left that car in Scotland The drive back on the tyres was bad enough ;I got outdragged by a lorry on the M6 in cold Scotland!: retrorides.proboards.com/thread/113427/1998-peugeot-106-tatty-daily?page=1 |

I've got no argument with any of that :-)
A mate and I have recently acquired a tyre changing machine so we can strip tyres off and refit relatively easily (so far only used it for rally tyres, my recent tyre purchases for the road car have been new and fitted at the dealer's). It won't make me keener to put part-worns on either car, TBH, as quite simply you don't know what you are buying (notwithstanding your comment about part-worns on a S/H car).
I shop around quite happily and have had good deals via TyreShopper, with the tyre fitted by the local National dealership. Fairly hassle-free too.
Interesting in your linked article about the out-of-shape tyres - had that on the back of an Astra estate and it felt positively dangerous. <shudders at memory>
I used to rally 205GTis (1.6s) and they were like a mental turbo nutter rollerskate. I also did a few rallies in AXs and they were a hoot, I loved how light they were, could skate over the rough stuff.
