We could go on and on about tyre safety, and we usually do. However, instead of just telling you what you need to do, TyreSafe and us here at Kumho have answered your frequently asked questions regarding tyre safety!

  1. How often should I check my tyres?

You should ideally be inspecting your tyres on a monthly basis or before any long journey. It is essential you keep a close eye on your tyres during the winter months. When checking, include the air pressure, tread depth and overall condition (including the spare).

  1. Where can I take my tyres?

We have plenty of Kumho dealers that will be more than happy to inspect your tyres and supply you with more (if needed of course!).

Find your local dealer here: http://kumhotyre.co.uk/dealer-locator/

  1. What is the minimum legal tread depth and why should you not exceed it?

We’d like to hope you all know this one…but we couldn’t leave it off the list! UK law requires car and van drivers to have at least 1.6mm of tread.

Those who fail to comply with regulations could face a fine of up to £2,500 and three penalty points for each tyre. Incentive enough to check them monthly!

Tread depth is also essential for good grip on slippery roads, as the tread pattern helps remove the water from between the tyre and road surface. If your tread depth is below the minimum requirement, you may face longer stopping distances, reduced grip and a higher chance of aquaplaning.

  1. Why is tyre pressure important?

If tyres are under or over inflated, handling and grip can be reduced, causing irregular or unpredictable car behaviour.  You are also more at risk of a blowout and your car may be more susceptible to damage.

Over-inflated tyres give you less contact with the road, which results in less grip and a less comfortable ride. If your tyre is correctly inflated, your tyre will not only last longer but reduce running costs. Double bonus.

  1. Where can I find the correct tyre pressure?

If you can’t be bothered to search through the manufacturers’ handbook, you’ll also find the info inside the fuel cap or drivers door. You can also ask your local tyre dealer, who will be more than happy to help!

  1. What causes irregular wear?

From scuffing your tyres against kerbs to aggressive driving, irregular wear can be caused by a number of factors. Check your tyres monthly for signs of wear.

  1. How many miles will my tyres last for?

Tyre life is very much dependent on how they are used. If your tyres are used exclusively on motorways and are well maintained, you are much more likely to return a higher mileage against tyres that are badly treated or those used largely in urban environments.

  1. Why should I have winter tyres?

When the weather drops below 7 degrees celsius, tyre tread can harden meaning less grip on the road. Winter tyres are designed to combat this and cope with the snow and ice, remaining pliant in cold temperatures, providing more grip and shorter stopping distances.

  1. Do I need all new tyres at the same time?

Ideally, we’d recommend fitting new tyres at the same time, however if this is not possible, try to fit tyres as a pair. Before you replace tyres, seek advice from a tyre retailer (we have plenty of expert dealers nearby to help!).

  1. Hi I have Khumo ecsta sport ku39 tyres on the rear of my car . 275 35 r19 and I’m suffering with vibration between 60 and 75 mph . (Only sines haveing these tyres. I’ve had the wheels re balance several times an the issue remains . I have now checked the run out on the tyres . In seeing run out of ~2.7mm over about 36 degrees , the rest of the circumference is nominally consistent.
    What are is considered to be acceptable ?

      Hi John,

      To be sure that it is the tyres that are at fault, the radial runout of the wheels should be measured first. The high spot of the wheels should be aligned with the low spot of the tyre to reduce radial runout as much as possible.

      However, if the problem only existed since fitting the tyres, it could be that the tyres are contributing to the problem. If this is the case, we would recommend that you should return the tyres to the dealer under the warranty complaints procedure.

      Please get in contact with us through http://www.kumhotyre.co.uk/get-in-touch/ and we would be able to forward on to you details regarding the warranty procedure.

      Hope this helps.

    Hi There, I am looking for tyres for my Motorhome and like the Khumo 857 – can you tell me if they carry M&S markings – Tyre size is 195 R15

      Hi Ross. The “857” pattern does not carry the ‘M+S’ marking. Any more questions, please get in touch.

    Hi,
    I have the Kumho 235/45ZR18 98Y XL fitted on my van and have found the maximum psi of 50 but not the recommended for everyday use psi, I have been sticking with 32 up until now. It is a VW T4 swb van.
    Thanks

      Hi Kevin, thanks for getting in touch. The best recommendation would be to follow the advice in your van’s user manual. This should state the pressures that are best suited for your van.

      Hope this helps. If you have any other queries, please let us know.

    I have purchased a secondhand motor caravan with Kumho 857 tyres on the rear. The size is 235/65 x 16 on a Mercedes Sprinter. I cannot find anywhere on the outside of the tyre, the standard date code for the manufacture. I suspect that these tyres – although they still have 6mm of tread, may be getting towards 5 years old, which is when I would change them, having had a blowout form older tyres before.

    Is there a different code on the tyre, or is the code on the inside of the tyre – which of course I can’t see as the vehcice is quite low ?

      Hi Mick.

      It is common practice to fit tyres with the date code facing outwards. It is not always possible to fit the Date code to the outside, for example with directional tyres, but this is not the case with the Kumho 857 pattern, it is not directional so there is no reason not to fit the date code to the outside.

      The date should be visible in the following format: XYZ C0AX YA6L 2016 (for example), with the last four digits showing the date. If this is not visible on the outside sidewall, it must be on the inside and I think wheel removal will be the only way of reading it.

      Hope this is helpful. Good luck.

    Hello,
    I wish to ask how much pressure to put into my Kumho Solus KH17 tyre that I have bought, I have put the recommended 31 psi in them but they look flat so I have put in the 44psi the tyre says however my dad is concerned that they will blow as he has never seen pressure this high in a tyre before? can you help?

    Thanks Oliver

      Hi Oliver. The vehicle manufacturers pressure recommendation should be followed. 44psi is the maximum pressure the tyre is designed for, it is merely there to prevent people dangerously overinflating their tyres. Higher pressures than those recommended by the vehicle manufacturer will result in poor, possibly dangerous, handling and accelerated wear.

    Hello. I’m driving a Land Rover 90 with Road Venture MT KL71 tyres but struggling to find the correct driving pressure for day to day driving on roads. Can you help, loosing control often which is dangerous. Also I’ve found these tyres not great for compacted snow on winter, is that normal?

    Thanks

    Mark.

    Reply
    • Hi Mark, the KL71 is a Mud Terrain tyre designed primarily for use off road. However, most of the testimonials we hear refer to it as having acceptable road manners. The advice we would give is to start with the manufacturers recommendations for tyre pressures but monitor the tread wear and make small adjustments accordingly. It may be advisable to increase your tyre pressures marginally because you are using a bigger tyre than the OE Land Rover fitment.

      There are very few tyres that will work on compacted snow, only “siped/studded” winter tyres give reasonable grip in those conditions. Hope this helps!

        Thanks for this. Can you possibly tell me what the manufacturers recommended pressure would be and should there be a difference between front and rear.

        I’ve heard and read different reports.

        Thanks.

          Hi Mark, the recommended tyre pressures for your car will be in the handbook but sometimes they are also written on a stamped plate just inside the door pillar on the drivers side. We can’t tell individual manufacturers pressures as they vary from year to year depending on the actual age, model within the range, etc. Sorry if this is not quite what your after but hope it helps!

    Hi …..my wife ran over a curb damaging a rear tyre. The local tyre shop says she cant buy 2 2nd hand tryres and have them fitted because the weight rating is 99 on the 2 ….2nd hand tyres and not a match for our 2 front tyres with a rating of 95…. is this true?

      Hi Chris. From you IP address we can see your in Auckland so suggest you go to another tyre shop and get an opinion if you’re unsure as we can only advise on UK regulations and guidance where mixing tyre loads, speeds, etc is not advised and in some cases can make vehicles fail UK annual tests under UK law. Thanks.

  9. Hi, What is the weight of KU39 Le Sport 205/45/16 tyre please? Thanks.

    • Hi. It might be possible to fit KH17 but you would need to check your tyre sizes and seek advice from your local Kumho Dealer to make sure. You should also only fit tyres in axle pairs so please ask the dealer about this too. Thanks.

    On rear drive cars (Rover 600 series) is it not better to fit new tyres on the front?

    Hi,
    Can you tell me if I align the red dot or the yellow dot with the tyre valve on a Kumho Solus KH17 tyre? I always understood that the red dot took precedence. I realise this is just the starting point in balancing a tyre.
    Many thanks

      Hi Stephen, you’re right regards the red dot – 10 points! Red Rules is the general pointer so if there is only a yellow dot it indicates the lightest point of the tyre and should be aligned with the valve. However, if there are both yellow and red dots, the red dot takes precedence and should be aligned with the valve or with the “dimple” in a steel wheel should there be one. The red dot indicates the point of highest radial runout/variation. So always align the red dot to the valve as the rule. Hope that helps. Thanks.

    Hello

    I have just had two Kumho Ecsta HS 51 tyres fitted to my four year old Mazda 3. They are 205/50 ZR17 93 W with the date stamp 1415.
    Your website describes the Ecsta HS51 as having four circumferential grooves but my tyres have only three. Have I been sold old stock and are the tyres OK for my car? I have always had excellent sevice from the garage I bought them from. I do about 8000 miles per year, about two thirds of which is motorway driving.

    Reply
    • H Paul. Kumho Ecsta HS51 do have four grooves. There’s 3 solid grooves and one detailed groove. If you are still unsure please do send us a photo of the tyres to digitalteam@kumhotyre.co.uk and we’ll take a look for you. HS51 is a great tyre so they will be perfect for your Mazda 3 and the motorway miles! Thanks.

  13. Hi there,
    Would you please advise me re your Ecowing kh27 tyre, is directional? This sort of info would be useful to consumers when considering a purchase,
    but does not appear on your website with other tyre info.

    Many thanks,
    Martin

    I have Kumho 175 x 13 C on my 1999 caravan. Can someone tell me where the date code is? I am concerned the tyres may be out of date.

    Reply
    • Hi Greg, the date code will be stamped on to your tyres and will be a three digit or four digit code – for example “176” or “3003”. If you find that code we can tell you when they were manufactured. The code will be near the tyre size letters/number but will be much smaller in size. Feel free to email us at digitalteam @ kumhotyre.co.uk with the code. Thanks.
