We have a 2009 Volvo XC60 T6 and are considering fitting all terrain tyres. However whilst I know the load rating and speed rating of the current tyres I cannot find what the recommended load and speed ratings are.

I am considering fitting Hankook Dynapro RF10 ATM 235/60R18 102T.

Are you able to help with the recommended speed and load ratings.

Many thanks.

Hi there,
I found the specs here:http://www.hankooktire.com/au/passenger-cars/hankook-dynapro-at-m-rf10.html

Many thanks for your help. However, I was aware of the specification of my potential replacement tyre (102 load rated and T speed rated, as listed in the tyre description).

My issue is that I cannot find what Volvo suggests as a minimum tyre load rating and minimum tyre speed rating for my car and I cannot find a way to contact Volvo online to ask this.

If this is not available:
Load Rating:
Is it reasonable to check the maximum suggested axle loads (which are on a sticker on the car) and divide this by 2 to give the potential load on each wheel (per axle), and then check this against potential tyre load ratings, to give a minimum tyre load rating to use?

e.g.
Listed front axle max load. 1290kg / 2 = 645kg
Listed rear axle max load. 1200kg / 2 = 600kg
I have found that load Index 93 = max.650kg
Am I therefore OK as long as my replacement tyre has a load index of over 93?

Speed Rating:
The T speed rating for my potential replacement tyre will allow speeds of up to 190km/h. This is obviously faster than I would ever drive. Will this therefore be acceptable to my insurance company even though the car came with higher speed rated tyres from new?

Many thanks

Hi there,
Ah now I understand.
I can't speak for the insurance company, but for a wof the tyre speed rating must not be lower than the max legal speed limit of the vehicle (100km for NZ). 190km/h should pose no problem for NZ roads.
102 load = 850kg which would be well inside the vehicle max permissible load rating. The method of dividing the axle loads to achieve tyre load reference points would seem to be the right way of obtaining this information. Do you know what the ratings are of the tyres you are taking off and were they fitted from factory?

They are currently 103, but they are replacements added by a previous owner.

This chart shows that some of the versions with 19inch wheels had 101 load rated tyres whilst others had 105 load rated (although this is in the US and Canada). However I do not know the
