    I am a big fan of the Michelin TRX tyres and without doubt thatt is what i would want fitted if I had a Mondial. However i have recently found a listing mentioning 16" wheels on Mondial.

    Pirelli have recently made some period P7 tyres in 16" https://www.longstonetyres.co.uk/pirelli-collezione/cinturato-p7.html i wondered if they might be of interest to you?

    Also if they did fit 16" i would like to update my page https://www.longstonetyres.co.uk/classic-car-tyres/ferrari/mondial.html so any data and imagery people might have would be gratefully received

    From what I have read and been told, they went to 16" wheels midway through the 1987 model run. My car, made late in the run, has factory 16's on it.

    I'm sure there's more Owner's Manuals in addition to these.

    From what I see the 16" P7 is specified for the Mondial t, and obviously it's period correct for all Mondials using the 7J x 16" wheel.

    Hi Longstone Tyres ,

    My car is an 88 USA 3.2 cabriolet , my car still has the original spare tire ( Goodyear Eagle ) . Same as fellow member Dino 2400 . It’s a good thing your manufacturing / making the original tires for the Classic Cars .

    Those P7s look geat. I had considered the modern P7 when replacing my tires at the end of last year, but didn't care for the sidewall design. It just didn't look right to me and I went with a set of Coopers instead that matched the specs that I was looking for and also had a more period-looking sidewall.

    It's good to see that these (resissues?) are available in the original design.

    Oo. sorry i think that is wrong. The P7 is a period side wall design. The side wall design did change a bit in period but the design on the side wall is Pirelli making the tyre so it loooks as close as possible to the way it did in period.

    this is a period advert

    However i don't think the Cooper is. I think they will be totally modern

    However the difficulty is that you guys want a 225/55R16 as a rear tyre and we only have https://www.longstonetyres.co.uk/classic-car-tyres/ferrari/308/225-50yr16-pirelli-cinturato-p7-n4.html which is a shame. Sadly it is nearly an inch smaller in diameter

    Hi, Dougal
    I did put the new michelin 390 tires on this week on the original wheels. Looking good, just a note : for balancing we did need a lot of lead on each wheel ...about 120 grams, at the outside and the same on the inside. The tire man seas its not the wheel but the tire.

    hmm! that would be remarkable if that was the case all Michelin tyres are tested very thoroughly. In my mind 120g is erring towards maximum weight i would want on a wheel.

    Might i be right in guessing that the weights are almost 180 degrees apposed to each other?

    And if you found that all the tyres were dramatically out of balance, then try another balancing shop.

    No, that is just odd...it is all at the same level outside and inside...will try an other shop for verifiing.

    what i'm guessing is that on the outside of the rim you might have a load of weights at the top, then on the inside of the rim you might find a load of weights at the bottom?

    I would go to another wheel balancing place.

    I don't think that 120g per wheel is absolutely terrible. for us 120g is the border line. if we need 120 g we would spin the tyre on the wheel. if it is just 115g then its fine. It is odd to have that much with a Michelin. It also looks worse because they are zinc weights which are just bigger.

    It is worth looking at the wheel on the balancing machine as it spins. to check for trueness.

    There will always be a slightly heavy part of the wheel, and a slightly heavy part of the tyre, and they sometimes land together which is unlucky, but can be fixed by spinning the tyre round 180 degrees on the wheel.

    you can only truly test a wheel with out the tyre on and check the bead seat - the bit where the tyre sits on the rim.

    Try another garage. they might even be able to balance them without having any weights on the outer bead seat.

    I thought you might find this comment interesting

    "I took your advice and used the P7 set up suggested for the late Mondial 3.2 on my 1989 328 GTS. (same tyre dimensions). Perfect period look, ride, and handling. Thanks Dougal."

    which was just posted on this film

    I was a little concerned aboout the diameter of the rear beinmg a bit small, but as you can see in the film the P7 225/50R16 Pirelli is the smae diaameter as the 240/55R390 TRX so your gearing should be OK.

    Don't get me wrong i am still a massive fan of the TRX. and i would want TRX on a Mondial if i had one. the TRX drew incredible ride quality from such low profile tyres. But if you are on 16" wheels there is no need to sacrifice the handling by fitting inappropriate modern tyres carcasses, that are designed to be used on a different kind of car. I was very pleased to receive this comment backing up my views
