    Banned
    bought 2 michelin tyres -

    195 55 15 87v
    and
    195 55 15 91v

    guy i bought them from said this is perfectly fine to fit to the car.........is this correct?

    Isn't this the load they can take?

    Speed rating is the letter, load rating is the number.

    Personally, I think it would be fine.

    Guess it would depend on the rating the car should have, they could both be wrong for all we know.

    I'd go on one of the tyre sites where you put the reg in and it gives you the tyre required, if the load rating is above that then it should be fine.

    car came with 87v

    i wanted to keep it the same kinda tyre on it.

    speed rating may scupper this

    It will be fine, unless you drive a mini? Then its probably best if you replace all 4 tyres and front & back brakes to be safe.

    why two different tyres, are they part worns?

    greg, yea part worn. they cost over 100 quid new but have 5.5mm on them

    Basically what you have is:

    the 87V are Load rated at 545kg @ 149mph
    the 91V are Load rated at 615kg @ 149mph

    So its not a case of legality as the rolling road of the tyres makes no difference as they are the same size.

    As long as they are within the tolerances for your vehicle then there should be no issue in regards to safety.

    As far as I know you cant pass an mot with different load ratings on the same axle. I used to mot years ago but I have a peanut for a brain.

    MOT Regs on Tyre Inspections

    Only Class 5 & 7 are inspected for Load ratings it would appear.

    A Car is generally a class 4.

    The shudder could be numerous things.

    Poor Balance, warped rims or just a bad tyre, both don't have to be bad to cause a shudder it could have been one side.

    It could even have been a warped brake disc or sticky caliper.

    its legal.

    Should make no difference as the original tyres on the car are a lower load rating tread pattern and rolling road identical so in theory these would be less likely to blow out at 149mph (haha)

    I agree though its good practice to keep matching pairs per axle.

    Agreed on the part worns though never been a fan.
