    replacing tyres all round and taking advice from forum am using metal valves, local garage is fitting for me asked I supply valves with tyres, when I look around I find this on tyre supplier website

    How often should I replace my rubber tyre valves?

    Once every six months, when changing your tyres.

    I shall be afraid to go out on my own soon!

    That isn't correct.

    You should replace the valves when replacing the tyres.

    You should look to replace the tyres after they are 5 years old.

    Meant to ask Does the use of metal valves apply to steel rims or just alloys?

    If you're in Louth you should go and talk to Andy at Lincolnshire Tyres, he'll put you right.

    Will do Today! (have asked at another brand of tyreshop in Louth and was advised not to bother with metal valves!!)

    I took metal valves in with me when I was getting the tyres refitted after having the alloys powder coated. There wasn't enough room to get a socket over the nut in the alloy recess, so couldn't fit them. Tyre guy fitted rubber valves and said they do get more problems with metal valves.

    Metal valves are OK for tractors and stuff. I wouldn't use them in alloys. :(

    I was told the reason for metal valves was because of the higher psi in the tyres compared with a car. I don't know how true that is though.

    Always fit metal valves if you are running at 55 psi or higher. Never run our vans on anything less the metal valves.

    I refurbish wheels for a living been doing it for nearly 20 years . So a bit of advice if you use metal valves on alloy wheels generally they will start to corrode around the valve hole . I don't know the science around it but think its some thing between ferrous and non ferrous metals reacting to each other.

    use brass valves then both the wheel and the valve stem will be nonferrous

    Just to finish this post here is the reply I received from Hankook, may help others decidewhat route to take

    re your enquiry, concerning tyre size 215/70R15


    If the tyre that you have fitted is 215/70R15c 109/107S Hankook LT Vantra (RA18), this tyre is designed for light commercial vehicle application.

    The specification of this tyre: 109 = 1030kgs per tyre Single wheel application (2 wheels per axle) at Max air pressure of 65psi

    107 =975kgs per tyre Dual wheel application (4 wheels per axle) at Max air pressure of 65psi

    S = Speed rating of 112mph


    If the tyres are to be used in a campervan/motorhome application, it is strongly recommended that a 10% safety margin reduction is applied to the tyres weight capacity.


    Given the axle weights that you have declared are deemed to be accurate that you have checked weighed the vehicle and axles at the operating weights to be used.


    Front axle weight of 1650kgs tyre pressures = 56psi

    Rear axle weight of 1750kgs tyre pressures = 60psi (2 wheels per axle)


    Thank you for contacting Hankook Tyre
