Well If you really need to change them, then go with the PS3's. If they are still at 3mm or better they would probably be ok until the Primacy3 arrives. What I would say if the rears were too worn you'd have failed the MOT On the Fuel efficiency, it comes down more to testing differences between standard and extra load tyres, the actual difference in service wouldn't be significant. Are the rear tyres on the wear bars? If you don't do big mileage, then you could wait for the Primacy3 if they aren't

Neville How worn are the tyres on the car at present? In what way do you think the XL (97) load tyre will have a better mileage? It's fairly irrelevant..

Hi The Latitude Tour HP is a good all season type of tyre Whilst it doesn't have the deep snow/heavy winter capability of the Alpin range, it's good on light occasional snow, and copes well with temperatures down to around -20. So for UK winters it's more than capable It also gives a good level of wet performance, which to fair is what we experience for the majority of the winter Also has a better performance if you go occasionally off road, so anything from wet grass, to sand and light mud. I've recommended it to many consumers over the years, and never had one come back saying they hadn't found it to be a good tyre for their needs.

Neville Thanks for your post I'd actually advise you to wait a couple of weeks if you can. We are launching the Primacy 3 in 245/40-18 at the start of June (product code..199410), as it gives you the best of both worlds. It's a good step forward over the Primacy HP and has a great level of grip wet and dry. Unless you drive the car "hard" I'd go with this one over the Pilot Sport 3 any further queries, or if you struggle for availability, let me know

Ashar we say when you start seeing 7 celcius or lower on the dash (or if you hear it on the news if your car doesn't display a temp..) That doesn't mean the tyres only work below 7, it's just a fair representation of the temps you tend to see October through to March/April time.. You don't need to wait for it just to snow.. they work particularly well on a winter road that's cold and damp

Ian tram-lining is basically the tyre following the grooves worn in the road by trucks or other heavy vehicles. The wider the tyre then the wider the contact patch, therefore increasing the likelihood statistically of finding a groove Equally the shorter the sidewall height (aspect ratio) the more direct the movement from the tyre back up to the wheel. Hence a wide low tyre will always be worse than a tall narrow one. Always bear in mind that due to road camber and UK road layouts, the most common form of wear is the outer shoulder of the NSF tyre. (you only go round roundabouts in one direction for example...)

Running a winter tyre in the summer will lose you a little in braking distance @ 50mph, on a dry summer road you will lose about 4m braking, and the tyres will feel slightly lighter during the braking, but the car will stop in a well controlled manner still. Similar figures on a wet summer road. So if you never drive hard, you may never feel the difference, beyond that a touch more noise, but only slight Best is always right tyre for the season, but the losses in winter with a summer tyre are vast.. so running a winter tyre in summer isn't perfect, but it's never a vast difference

Ashar labelling is complex, but let me answer your questions. Labelling testing is self certifying. E.g. we test our tyres, other brands test theirs. However, we will test other brands too, simply to cross reference and verify. However, the European regulatory bodies have now started testing people tyres against the published results and in a few cases have penalised manufacturers for not meeting the labelling results in testing. Michelin follow the regulations for the testing completely, but we also go further, for example we aim to test summer tyres as close as possible to 20 celcius, and winter tyres at 5 celcius. The regulations allow wider temperature windows, but the results can vary dependant on temps, so a manufacturer could decide to test when the temp best suits. Which is why we test at temps where the tyres actually run. Otherwise you develop products that are "false" for their use.. At Michelin, we have a philosophy of Total Performance, so we consider a lot of other performance areas other than the labelling results, so we never make a tyre just for the label. It's easier to attain a good wet grip rating than the Rolling resistance figure. However, you can compromise a tyre a lot, just to get one result. For example a hard hard compound or a light thin tyre can achieve good rolling resistance. This isn't something Michelin would do. We aim to be good in every area. we aim to be in the green zone for all our key ranges (e.g. C or better) A wider larger tyre is always going to be worse in rolling resistance than a thinner smaller tyre. It's simple physics. Wet grip is quite simple. Each band e.g. A->B in wet grip is approximately a car length of wet braking from 50mph. So from the best to the worst you can get 15-18m worse. So the length of a 40ft Truck and Trailer. That's worth the extra money for a good Premium tyre. Michelin own the mid range BF Goodrich brand, and Kleber, and in budget Kormoran/Tigar & Riken

On a 4wd our advice is simple. Same brand and pattern. and no more than 4mm of difference between axles. All tyre brands have to adhere to the ETRTO regulations on sizing (European Tyre & Rim Technical Organisation). There are levels of tolerance. Hence one manufacturer may make to the minimum one to the maximum. Hence that's why I'd recommend not mixing them. In some instances if your 4wd is heavy on one axle, it may be worth occasionally moving them from one axle to another, evening out the wear. Yes, you'll end up probably needing four tyres at once, but if the pattern and tyre type has been replaced (we tend to change specs every 5-7 years), you can end up trying to by 2 and not being able to get them.

Ian I couldn't agree more. Yes, in general gone are the days of "my michelin's/goodyear's etc.. used to last 80,000 miles.." Why, because, cars performance and drivers expectations have increased significantly over the last 30 years. If we look at an average family hatchback like a Ford Focus, the on average have a minimum of around 120hp, 16" or 17" wheels as standard, with complex suspension systems and powerful brakes. Compare that to a 1985 Ford Escort, with 75-90hp and 13" or 14" wheels. Are cars performance has improved, tyres needed to improve to cope with the performance improvements. So with Premium tyres, yes, the extra grip has in general been needed, as the cars have so much more potential. Therefore, with the increase in grip there has been some differences with mileage attained, but it's not all down to the tyres. That 1985 Ford Escort, will never work it's tyres like the 2014 Ford Focus. So really you can't compare, as they aren't the same. I often say to drivers and consumers, that the only reference you have for the mileage you attain, is your car, on the roads you drive on with you driving it. So the only mileage comparisons are with the car you have, and even then it changes as the car ages (suspension and component wear and tear..) Lastly, you always may find some options, for example on the 17" sizes for the IS's we will offer Pilot Sport 3 and Primacy 3. So the Primacy may give you a better compromise if less sporty... And the final word is.. really for people trying to save money on tyres.. The one time you need the car to stop or steer or grip.. you want the absolute maximum amount of grip. £20-40 a tyre extra vs. the costs of an accident and your health.. really can't be summed up easily.

Dan, apologies for the delay in getting a reply back. This is a tough one to answer without being critical of competitors, or sounding pompous but I will give it a go... Why are we different? We've lead a lot of developments over the years, and continue to spend more on R&D than any other tyre company. So if you have a Michelin on the car, it's a fairly high probability it's at the forefront of current tyre technology We have a philosophy of Michelin Total Performance. what does that mean? Quite simply that we want our tyres to bring together lots of different areas of performance, including safety, fuel efficiency, wet and dry grip, longevity etc etc. So while Tyre X may perform slightly better in Test Y with Magazine Z, we develop our tyres to give more overall performance to more consumers and manufacturers. We make tyres that work for more people more of the time, for longer We build a lot of our own factory machinery. Sounds simple, but it means we aren't constrained by the machines. If a designer needs a tyre built a certain way and there isn't a machine to make it, we make the machine. It gives us scope where others are constrained by the ability of the machinery. We actually use motorsport for product development, not just as a marketing exercise. So what you cry... i don't drive a sports endurance or rally car.. well the lessons we learn developing tyres are applied to our road tyre range, very often by the same designers. So again visible with our Pilot Sport ranges, where we use motorsport compounds and materials in road tyres. Apart from that we have the friendliest and most knowledgeable staff :D

Sadly (well understandably I suppose), the budget winter tyres never do quite well in the tests compared to the Premium or Mid line tyres. As with summer tyres, Premium manufacturer's do have the best technology, materials and R&D so their advantage over the budget brands is the same really. And the advances in winter compounds and pattern and sipe technology, aren't easy to replicate. Michelin, as with most of the Premium brands to have their own ranges in 2nd line, which quite often can be based upon the premium tyre of one/two generations back. So that would be a good compromise. I would personally avoid the budget ones, especially on a quiet well engineered car, like a Lexus..

James I'd always say minimum axle pair. Whilst you may never lean on your tyres hard enough, i think having a "balanced" set up, e.g. one where you have the same potential across the axle, means you won't have different behavior in different turns. So if you steer left or right, it's the same. Plus removes any element of "pull" under traction or braking. Some European countries actually have same tyres on an axle as law..
